Bridges in the United States are getting older and in desperate need of repair. Some of those bridges, like the Hernando de Soto Bridge across the Mississippi River that needed to be shut down for three months last year for emergency repairs after a large crack was found in a steel support beam, are huge structures on major interstate highways critical to the nation’s commerce. Other bridges, such as the Forbes Avenue Bridge in Pittsburgh, which collapsed in January, are not quite of national significance, but are important to the region. Still others, such as, say, the bridge on Edgewood Drive in Lenox, Massachusetts that collapsed in heavy rains last summer, matter a great deal to the people living in the seven homes on the dead end side of Edgewood Drive, but otherwise don’t have tremendous economic impact.
While it is no secret that a concerning number of American bridges are “structurally deficient”—a Federal Highway Administration definition that means “at least one major weight-bearing component of these structures has serious problems and is in need of repair or replacement”—few if any studies have tried to find out if there are any patterns to the structurally deficient bridges in terms of who lives near them and which ones tend to be most neglected.
Sign up for Motherboard’s daily newsletter for a regular dose of our original reporting, plus behind-the-scenes content about our biggest stories.
But a recent study from the Massachusetts Budget and Policy Center did just that for the bridges in the state. Using a database of some 8,000 bridges by the state’s Department of Transportation, it found there are 644 structurally deficient bridges and another 218 with “unknown” condition, meaning one in 12 are structurally deficient. And Massachusetts residents of color—designated as any race other than non-Hispanic white—are more likely to live closer to a structurally deficient bridge than white Massachusettians. Residents with limited English are even more likely to live near a deficient bridge.
“To our knowledge, there have not been previous studies of disparities between different groups’ proximity to structurally deficient bridges,” the authors wrote in a footnote.
Moreover, the authors found the disparities are not just a function of minority populations being more likely to live in urban areas and therefore more likely to live closer to bridges. In fact, people of color were not more likely to live closer to bridges in general, regardless of condition; they were only more likely to live closer to deficient bridges. “Thus,” the researchers wrote, “the disparity appears in part to be specifically linked to the disrepair of infrastructure.”
While the study covers only Massachusetts, it echoes recent findings from a Government Accountability Office which found neighborhoods with high rates of family poverty, concentrated minority populations, and urban areas are more likely to be near highways in bad condition.
It is not exactly clear how structural racism manifests in Massachusetts bridge repair. But the concept of structural racism leading to unequal infrastructure quality has been well-documented by researchers for decades, whether it is where highways are built, who has access to green spaces, quality public transportation, or any of countless other metrics. But the study authors did reference another recent academic study which showed communities with higher proportions of people of color pay higher interest rates when they borrow money than whiter communities, a dynamic “unexplained by credit risk.”
The study also warns that the state’s bridge condition is only likely to get worse as its already old bridges get even older and extreme weather more likely due to climate change damages bridges at a faster pace.

Real Estate, Construction, Roads, Aviation, Marine Transport, Power and Energy, Gas Grids
Infrastructures projects not only contribute to the country’s GDP but also create job opportunities for the residents thereby pushing the government’ vision of employment.
Apart from this with PPP (Public Private Partnership) and FDI (Foreign Direct Investment) grooming in the infrastructure segments has led to a strong bonding of government agencies and private sector giants leading to improved serviceability standards for the common man.
The above paras highlight the importance of infrastructure projects from the view point of revenue generation, employment and economic growth of the country.
The infrastructure segment is broadly divides in the following segments
- Transportation – Highways, Railways, Ports and Airports
- Energy – Power Generation (Thermal, Hydro, Solar, Wind power), Power Distribution Petroleum, Coal mining
- Urban Development – Affordable Housings, Smart City Infrastructure
- Telecommunications – Broadband, FTTH, Mobile Connectivity, Managed Services, Hosting
- Engineering – Steel, Fertilizers, Heavy Electric, Mining
Each of the mentioned infrastructure segments have evolved over the years to provide better services to the users and trends for each of them are different when we talk of technicalities and design aspect.
But some trends are common for all of the above mentioned infrastructure segments which they need to follow and adapt as the same will ensure investment protection, upgradability and scalability on the infrastructure that is being built. These considerations would ensure that the infrastructure would offer compatibility and adaptability to the new technologies. The details of these trends are mentioned
- Use of available data with sophisticated analytical tools will help decision makers to enhance the reliability of the projections which are used to divert the funds for infrastructure projects
- Designs should be flexible and planned with a vision that will facilitate investment protection and new technology interface
- Apart from Flexibility designs should be sustainable in terms of the investment being made and also the design should facilitate social sustainability so that the infrastructure benefits can be reaped by all sections of the society making it a win-win situation for the investor and the user.
- Designers should take speedy and prompt decisions for infrastructure projects considering disruptive technologies and technology obsolensce as the most critical parameters. This should be kept in mind while planning, designing and deploying infrastructure projects as delay in decision making may lead to non-usage of the infrastructure due to obsolete technology which in turn will result into financial losses.
- Automation and use of technology to optimize productivity and performance can make the infrastructure fragile and the risk of control going to the wrong hands is very high. In this scenario where infrastructure is data driven cyber and physical security should be planned, designed and implemented in way such that data is protected and it will make the infrastructure full proof with minimal chances of cyber attacks.
- With the use of data analytics etc. the concept of dynamic pricing is likely to rise where in infrastructure owners will charge the users in real time scenarios rather than using the concept of flexi pricing which is time based.
- In a data driven design concept of infrastructure with multiple data owners the concept of data sharing to bettering decision making and serviceability is bound to groom in the forth- coming infrastructure projects.
Having analysed the trends let us have a look at the technologies which are bound to impact the infrastructure vertical
- Augmented Reality – will give the customer the feel of the real world using camera lenses and help them to strengthen the decision making which for the developer is an advantage as it will lead to better conversions.
- MIS (Management Information Systems) – Integrating multi departments and multi-disciplinary individuals on the same platform and allowing them access of data from other departments for decision making and project planning will enhance productivity, optimize operational costs due to precision in defining timelines and also the analysis of collected data will lead to betterment of future project planning.
- Drones – With the innovations in Drone technology enhancing its precision and accuracy it is becoming a very important armour for the infrastructure projects which help in Arial surveys, site monitoring etc.
- Robotics – With manpower constraints the uncertainty on time lines to complete infrastructure projects looms large. This results in huge monetary losses for the developers. Process automation thru robots is the solutions and as the usage penetrates and adaption increases the same will lead to decrease in the cost.
- Cloud Hosting – Majority of the work force in infra projects is spread and working in remote areas. Project data accessibility for on field decision making is remote mobile office is equally important and to cater to this type of requirements usage of public or private cloud is the answer. Also since it supports scale out architecture CAPEX investments are almost nil and enhancement based on the project requirements can be done in hours which give the infra owner the flexibility to scale as and when required saving the CAPEX costs associated with owned systems.
- GPS Systems – This satellite based systems which have grown in precision and accuracy in real time monitoring and other task like survey facilitates project managers for managing the vehicle fleets, doings surveys and facilitating vigil of equipment’s fitted with GPS sensors.
- Wearables – For enhancing the worker safety.
- IOT’s – For Engineering segment where productions are related for getting real time information from various stages
The revolutionary technologies will not work unless and until the same is supported by properly laid infrastructure with supporting tools and accessories. We at Telecom and Management consultants recommend the following designs guidelines to ensure that the above mentioned technologies works well. The guidelines are:
- Green and clean energy is one of the most impacting factors in the infrastructure segment for reducing the carbon foot prints and creating an eco-balance. For the same we recommend use of solar panels or Windmills based on the availability of spaces in the infrastructure segment and apart from this one use POE enabled lightings with optimum usage of day light.
- The above mentioned technologies will generate huge data that has to travel to and fro from the data center in an unblocking manners and all the applications will use a single backbone as there will be convergence of ICT and MIS (Management Information systems). To cater to this and futuristic traffic requirements that is bound to generate lot of video traffic we should have robust scalable and upgradable converged networking backbone that would ensure seamless flow of traffic in a non-blocking mode.
- Wearables, Robots etc. need access of the network in real time for which high speed Wireless networks using secured high speed Wi-Fi or Li-Fi should be built along the site office and area of operation to ensures seamless connectivity for the Wearables, BYOD’s, Scanners and other telemetry and IOT devices which will transmit data over the IP back bone.
- Since MIS and MES will converge the foundation in the DC should be strong enough to provide processing capabilities capable of delivering data in line with the network speeds. For these we need to deploy high speed virtualized servers with SANs that SSD’s/Flash with high IOPS and enough storage capacities as per the application requirements.
- Create efficient and compliant intercommunication tools within the infrastructure project site and the main office.
- Support remote site offices with high speed WAN backbones using Service provider networks like MPLS or VPN over leased lines.
- Create mobile apps co linked to the master site for facilitating communication and real time data access related to inventory stocks etc. on mobile devices for the field and mobile staff.
This is just a brief of the setup we are recommending in general for more details contact us on firstname.lastname@example.org


Constructing a space or a home can be a pain. Before you actually see the results, you need to go through a number of construction woes, including managing the design and building of the space. However, building and construction experts suggest some methods that can make home construction a bit easier.
Modular construction is considered as one of the newest way of building a space. Using prefabricated materials, builders simply install the components and pieces to construct a space. But some people still prefer to go for the conventional way of building spaces. Modular building companies provided some reasons why you need to go for modular spaces:
For some people, modular construction might seem expensive at first glance, since the materials are a bit costly than your conventional materials. But if you look at it on another perspective, you will realize how cost-effective this method is. Since modular spaces can be installed in a timely fashion, you can easily use the space, especially if you use it for business. You can easily achieve your ROI in no time and lessen space vacancy. You can even do retrofit at a very reasonable rate.
- Time-friendly construction
As mentioned, this method can reduce construction time since the builders will simply install the components once the prefabricated materials are already assembled in the factory. This method can help, especially if you are crunching in terms of timeline. And if you want to finish your space faster, this is the way to go.
- Sustainable and eco-friendly
One of the key benefits of modular construction and space is that you can go for sustainable and eco-friendly homes. Modular spaces are built with the environment in mind. Since the construction is done mostly in the factories, there will be less digging and it will leave less environmental footprint.
- Flexible and scalable
Renovating a space can be time consuming and demanding. When you have a conventional home, you need to take some time planning how the remodeling would go. But with modular spaces, you can do some quick remodeling without tearing down the house. Since most of the components are retrofitted, you can easily make changes on the space like removing and moving wall, changing your interiors and adding space. You just need to contact your modular construction company to help you add some of these companies.

Offshore Windfarm Desk Study
Geo-4D have produced an integrated engineering geological and geohazard ground model for a proposed offshore wind farm development in the Irish Sea. An assortment of geotechnical, geophysical, and geological data was used to characterise geological and geotechnical variations across the site, and to present a set of geotechnical provinces and associated geotechnical profiles for front-end engineering design. The available data were also used to identify key natural and anthropogenic hazards and constraints to the proposed development.
Site-specific and publicly available data were used to document the evolution of geological processes and geological formations that have formed and shaped the present-day site, with focus on the shallow geology to 100 m below seafloor. The geological model forms the framework on which seismic interpretations, geotechnical model and hazard/constraint assessments are made.
The available 2D UHR seismic and sub-bottom profiler (Innomar) data were reviewed and interpreted to define five key seismostratigraphic units, interpreted to reflect the main geological units, each with distinct geotechnical characteristics.
The seismic horizons were depth-converted and exported as gridded surfaces that could be further interrogated in ArcGIS software.
A 3D geotechnical model was developed, based on the integration of the geological model, seismostratigraphic model, and available geotechnical data. The geotechnical model was used to predict geotechnical conditions across site, identify data gaps and areas of geotechnical uncertainty, and define geotechnical parameter bounds for use in engineering analyses.
The ground model was developed in ArcGIS software, and comprised an iterative integrated approach, split over five key tasks:
A high-level assessment of various natural and anthropogenic constraints (static features) and hazards (dynamic features/processes) was conducted, using available site-specific and public datasets.
Sediment mobility, shallow gas, anchor strike and trawling were highlighted as the main dynamic hazards that require further assessment prior to engineering, site investigation and development of the site.
Subsurface boulders, shallow bedrock, geotechnical variability, unexploded ordnance, existing infrastructure and wrecks were highlighted as the main static constraints hazards that may influence layout planning and site investigation.

in an ideal world, all outside concrete work projects could wait until the warmer months. But sometimes the construction schedule doesn't match up with Mother Nature and you have to start laying concrete when the temperatures are dipping well below freezing. There are a few tips and tricks you need to keep in mind before beginning the project to ensure that the concrete comes out stable, smooth and suitable for your project.
Use the Right Concrete Mix
Your concrete mix should include instructions for using hot water during the mixing process for a cold weather project. Make sure you follow the directions closely and ensure that both the water and the resulting concrete mix are at the specified temperatures. This process makes sure that the interior of the concrete doesn't freeze and weaken during the setting process.
Ask your concrete supplier to provide an accelerator that can also be mixed into the concrete so that it sets up faster in the cold weather. Note that if you plan to implant any steel beams or posts in the concrete, you want to make sure that the accelerator doesn't contain calcium chloride. This cheap material works well as an accelerator but will eventually eat through and weaken the steel.
Keep the Setting Concrete Warm
You need to keep the concrete warm during the setting process to prevent freezing and allow the mix to actually set up properly. Invest in some concrete warming blankets that cover the entire surface of the concrete to keep the mix warm enough to do its job. Resources like Powerblanket would have the necessary equipment.
Make sure that you put extra layers of blankets around the exterior of the concrete where it meets with the ground. This prevents the contraction and expansions of the ground from perverting the integrity of the concrete in those areas. You also want to wrap up any posts or beams sticking out of the concrete to prevent the same problem.
The warming blankets might need to be kept on the concrete for several days depending on the temperature of the air and surrounding ground. Keep checking the concrete underneath to see how the setting is progressing. You can also use a thermometer to ensure that the concrete is staying warm enough under the blankets.
Use a Wet Vacuum to Remove Bleed Water
Bleed water is essentially some of the concrete mix water that gets pushed to the surface when the concrete sets. The bleeding process tends to happen slower in colder temperatures but it makes it more important for you to remove the water as it appears so it doesn't freeze. A wet/dry vacuum is often enough power to remove the bleed water as it appears. Work quickly but carefully so that you can return the concrete back under the protection of the blankets to finish setting.Share

When I was in college, I lived in an old house just south of the university campus with five other girls. When we came back from Christmas break, the heater was broken. The beginning of January was the coldest time of the year, and because it was the weekend, the heating company couldn't come fix it for a few days. My roommates and I pulled our mattresses into the front room and slept all together to keep warm. Two weeks later, our heater broke again! That time we ended up getting a completely new furnace. Needless to say, we got to be good friends with the heating contractor that month, and it was a good experience that led to the creation of this blog.


Friday 7th November 2014 marked a significant day in the life of our school community. After many years of smells from the local waste site the final trucks were allowed to dump landfill. The site is now full. Over the coming six months the landfill site will be remediated but the smells from exposed food waste will hopefully be a thing of the past.
Thank you to our school community for your patience and choosing Covenant in spite of the smells. The site has been in operation for 49 years but apparently was only approved two months after Covenant was granted permission to operate a school on the Forest Way site. The closure of the landfill site has been promised for many years but delayed. An Expression of Interest for developing a Mountain Biking facility on the site will be available shortly. A Development Application and Environmental Impact study have been lodged.
Trucks will continue to access the enclosed Waste Transfer Station now owned by SITA. The waste from Pittwater, Warringah, Manly and Mosman will then be transferred to other landfill sites around Sydney. The plan is for Kimbriki Tip at Ingleside / Terrey Hills to take the waste in the future.


It took quite some time for the high-speed train connections to come to the Basque Country since the project was approved back in 1989, but finally the last details have been settled and in 2019 everything will be ready.
While the trains will link the Basque Country’s three capitals, Bilbao, Vitoria and San Sebastián, there will be also a national high-speed connection to Madrid and Barcelona.
San Sebastian will be then also linked to French high-speed train TGV, making travels from France much easier and faster. San Sebastian and Bilbao will both have a new and modern train station, located in the city centre of each city. Here is an image of the recently approved remodeling of the San Sebastian train station

The Hamburg Wheel Tracking Test is used to evaluate the resistance to rutting and the moisture susceptibility of bituminous mixtures. A small loaded wheel device repeatedly rolls across a prepared asphalt mix specimen. The test terminates at either 12.5 mm of rutting per set, or at 20,000 total passes.
AQUA PATCH was tested in 50°C water under a moving 158 lb wheel load at 50 passes per minute. The above result shows that the rut depth after 10,000 cycles is -2.18, and -2.68 after 20,000 cycles. Both depths are lower than the maximum allowance that is defined by AASHTO (American Association of State Highway and Transportation Officials). The AQUA PATCH material performed well in the test.
Test Method: AASHTO T324
Tested by the National Center for Asphalt Technology (ASSHTO accredited laboratory)


SA Needs To Curb Water Wastage
South Africans have less than 100 cubic metres of accessible fresh water per person, making the country the 30th most water scarce in the world. This is according to a report by the World Resources Institute.
In the past two decades, urbanisation in South Africa has increased by 68%, and this is projected to continue. “As people move into more densely populated areas, the demand for water increases,” explains Adronicca Masemola, head of public sector for KPMG in South Africa. “The resultant additional pressure on water infrastructure necessitates increased levels of maintenance, which places significant pressure on the budgets of cities and provinces.”
Inadequate water resources
The average annual rainfall for South Africa is 500mm/year, while the global average is a much higher 860mm/year. Not only are the natural water sources low, but the rainfall South Africa experiences is uneven and poorly dispersed. The wettest areas in the country are far removed from the industrial, urban and agricultural hubs in South Africa, causing even more headaches for water infrastructure.
In 2012, Financial Mail reported that Water affairs minister Edna Molewa said her department would need R668 billion during the next 10 years in order to manage the growing backlog in infrastructure.
Non-revenue water loss
Not only is the country faced with severe water shortages but it must also contend with water loss or non-revenue water which amounts to 36% or 480.9 gigalitres. Water loss is a direct result of broken or leaky pipes for which municipalities are unable to charge.
“To reduce the levels of non-revenue water, a number of key challenges must be addressed. These include monitoring, billing and maintenance,” says Masemola. “The implementation of effective systems to monitor water use at municipal level is crucial. Many municipalities do not monitor their use of water. Introducing monitoring is the first step that will enable comprehensive measurement of the extent of non-revenue water.”
Currently, rural municipalities have a non-revenue water rate of 72.5%, while metropolitan municipalities are averaging around 34.3% water loss. Rural municipalities have such a high water loss, despite servicing less citizens, due to poorer infrastructure. The simple fact is that they have less resources to be able to recover costs.
How to fix the water problem
Masemola says to reduce water loss, South Africa must implement effective management and maintenance strategies. If a better billing system is put in place then municipalities will be able to recoup more costs, and in turn improve infrastructures. Masemola emphasises that the water infrastructure needs to be improved as the first step towards eradicating future non-revenue water losses.
Masemola encourages municipalities to start thinking outside the box when it comes to redressing the water shortage and loss in the country. Once that mindset is achieved, then the country can start working towards reducing the scarcity of its fresh available water. “We believe that these challenges are most effectively addressed by combining technical, commercial and management skills, together with an understanding of the industry,” says Masemola.

solar thermal - solar hot water + electricity
Solar Thermal - harnessing the suns heat energy
Solar thermal technology comprises three different methods to convert solar energy for use. The first method collects the energy of the sun to heat water or air for direct use in solar home heating. The second method is used by large power utilities to indirectly create electricity through concentrated solar heat energy. The third method, known as passive solar, leverages energy efficiency and the design of a building to regulate the amount of solar energy it receives in order to regulate it's temperature.
Utility Scale Solar Thermal - Farming Solar Electricity
How is solar thermal energy converted into electricity?
Solar Power Plants or Thermal Solar Farms indirectly generate electricity when heat from solar thermal collectors turns water or molten salt to steam. As in fossil-fueled power plants, this steam turns turbines that power electric generators.
How do solar thermal power plants collect heat to produce electricity?
1) Solar tower: When surrounded by heliostats, which are special mirrors that track the sun, a solar tower collects the sun’s energy. The central receiver at the top of the tower collects and stores heat in special liquid salts that are transported from the tower to a steam generator.
2) Parabolic troughs: This kind of system uses the shape of a parabola to intensify heat and collect it from the sun no matter what time of day. Tubes filled with a special fluid run through this system. As the special fluid travels by, it warms up and essentially “collects” the heat. The fluid carries its heat to the water, which converts to steam and powers a generator.
3) Fresnal reflector: Instead of heating fluid, this mechanism heats water directly. It does this efficiently by increasing the atmospheric pressure. Steam is created to power turbines.
4) Solar dish: These move with the sun to collect heat all day. Using mirrors, dishes reflect sunlight onto a focal point. They convert this heat to mechanical power by heating a compressed fluid. The hot compressed fluid expands and powers a piston to create electricity.

Solar thermal for your home
Solar thermal is the most common form of solar energy used. The simple process of heating water with the sun is used throughout the warmer, sunnier climates of the world. Most homes have some type of water storage tank, painted black to absorb the suns heat. The water is used for showering, laundry and other household uses. It's not sophisticated, but it works. And it's free. The U.S. was a big user of solar water heating until gas water heating became popular. Solar thermal water heating is now making a big comeback because of environmental concerns and very favorable cost comparisons.
Solar thermal hot water heating
The most cost efficient way to implement solar thermal is through a solar water heater. Because most household energy is used to heat water for showers or laundry or dishwashing, having the sun heat your water for free is a great way to save money. Solar water heaters don't create electricity - they simply collect the heat from the sun and store it in a tank for later use. Solar heating works the same way the hose in your backyard works when it's exposed to a few hours of sunlight. The water gets very hot - typically rising 10 degrees per hour of sunlight. These systems are also fairly simple mechanically. The solar installer who implements these types of solar thermal energy systems has a background in plumbing.
Solar thermal water heating is also a great way to heat your pool and spa.
Solar thermal energy - hot air
Another extremely simple use of solar thermal for your home is a solar hot air collector. A solar collector made out of thin metal and painted black is fastened to the side of the home and air is circulated through it with a fan. Check out the video of the professionally manufactured solar hot air collector made out of used soda cans on the DIY solar page.

Using ecological materials and developing sustainable ways of building low-tech are important goals for many of the Nordic teams. Some of the teams also extend beyond the conventional role of architects by constructing the projects themselves.
The self-build method enhances a collective approach to work, where students as well as local builders and civic society are involved. Carried out right, both architects and local communities can be strengthened.
However, this work also raises questions of architectural and cultural prejudice. Ideas of desirability and modernity sometimes differ between a local community and a foreign architect. While construction of natural materials can be both beautiful, cheap and energy-efficient, it might require more maintenance on the part of the users. Finding suitable solutions requires strong local involvement and focus to project-specific circumstances. Collaborative building with gradual experimentation is one possible way of getting there.
Think bioclimatics on several levels
Turning a technical aspect into a central piece of the architectural aesthetics
“The aim of the project is to reduce the center’s dependency on private donations and eventually reach a self sufficient standing. As a strategic part of this objective, the new center must be sustainable and to a large extent maintenance free. Natural ventilation is integrated in the design and the center will produce its own electricity through solar panels.
The construction site is located on a remote area suffering from periodical drought. We have focused on studying the most suitable rainwater harvesting system to guarantee an adequate water supply. Inspired by the African Baobab tree, we made a point of designing the ferrocement water tanks as an integral part of the building’s aesthetical expression. The system is currently under evaluation and will probably be adapted for the next construction phase to meet the needs of the new Children’s Center. “

Benefit from local resources
Getting construction materials locally donated for the women’s center in Senegal
“Originally we wanted to use rammed earth for the building but it turned out that the local clay was not suitable for construction. Concrete was not our first choice because of its environmental impact. At the same time it came to be the most local and ecological solution since the largest cement factory in Western Africa was situated in Rufisque. We got the cement as a donation from the factory that was located only 1 km away from the site. The reinforcing bars that were also donated from a local factory were of recycled metal which added on the plus side. The window and door frames were welded in a workshop 50 m from the site. It ́s a challenge to optimize all parts of a project, and compromises always have to be made.”

Reduce, reuse, recycle
Adding earthbags and reused bottles to locally known building techniques
“In Situ cast concrete beams is standard for building loadbearing structures in this area, but using sandbags as fill-in was alien to the community. We knew it was a risk to suggest this, but felt we needed an alternative material with better thermal qualities than the concrete blocks that were normally used. The bags where bought cheap in the village centre, and sand was found next to the site.
Reusing bottle-bricks was a technique some of us had picked up in a previous course and wanted to try out. With no glass-cutter we had to split the bottles in two by using a thread dipped in gasoline, tying it on the middle of the bottle, lighting it on fire, and quickly putting it in a cold bucket of water. This caused the bottles to crack in two, so that they could be used in the walls for lightning.“
