london engineers recently converted the old Blackfriar bridge into a solar bridge. They predict the the bridge could produce about ... "The 4,400 photovoltaic panels cover the roof of the station and produce enough energy to make almost 80,000 cups of tea a day. In fact, London’s longest array provides up to half of the station’s energy, reducing its CO2 emissions by an estimated 511 tonnes per year – equivalent approximately to 89,000 (average) car journeys."
In regard to the project itself, I enjoyed the idea of converting old architecture into new, creative projects. Not only is it a energy effiecent product, it
In the globalized world, many countries still relay on coal, gas and oil as sources of energy. While these countries are still developing, and green alternatives becoming more economically viable, they are beginning to switch to green. In the long run, countries such as china will be able to become energy independent. Not only will they save money, but they will prevent themselves from relying on other countries, like we did in the middle east. Lastly, they will help better the environment!
The problem today with solar energy is it's unreliableness. When in full sun, they are great at producing clean, green power. However, in the shade or at night, they fail to contribute to the grid. This lack of consistency provides a poor cost effective method. "To store 50 hours of energy from a 1-megawatt power capacity wind turbine (50 megawatt-hours), for example, a possible solution would be to buy traditional batteries with 50 megawatt-hours of energy storage, but they'd come with 50 megawatts of power capacity. Paying for 50 megawatts of power capacity when only 1 megawatt is necessary makes little economic sense." Furthermore, the batteries are typically made from rare earth metals that leave the land destroyed.
A team of students from Harvard have begin designing a new type of battery derived from quinone, a product of rhubarb. The technology stores electricity in quinones, a metal-free organic (carbon-based) molecule similar to the chemicals used by plants and animals to store energy in biological systems. The quinones remain dissolved in water which reduces the flammability risk.
One advantage of this new battery is its ability to save precious earth metals. If the quinone is derived from rhubarb, then it is basically derived from solar energy. This gets around the issue of mining for rare elements that is a typical argument against chemical batteries. Also, rhubarb grows on very marginal land and is very hardy.
Shipping Containers are easy to move, hence the name. They can be sent to rural locals quickly and efficiently. A company by the name plans to install rollable solar panels within the containers. I could imagine a helicopter dropping these off in post storm places in order to provide immediate electricity. They believe the chief benefits to be
