Scientists Create Solar Energy That Recharges Itself

Scientists have discovered a way to harness solar power for indefinite use. This technology not only is able to be used with a minimum amount of sun exposure but also can recharge itself! If developed, it could be a game changer and allow for a limitless amount of energy for homes. So what is this magical system, and how does it work?

Photoswitching is a process in which a compound can be manipulated, and change forms via light exposure. In the case of this project, molecules would absorb sunlight in one form and then switch to another to store that energy indefinitely until its use. Using a substance called azobenzene and nanotubes, MIT and Harvard researchers were able to create a structure capable of producing a heat that generated over 200% efficiency. While a finished product is still very far off, a finding such as this has many practical uses.

With a small amount of energy, it could replace the grill in your backyard. A clear tank would allow the molecules to absorb energy from the sun and the energy would then be released through the metal coils of your grill with zero greenhouse gases. This would be handy for third world countries, which are plagued by air pollution from wood or dung burning in their homes. A device for this has already been designed by the scientists, who explain the process below…

On a larger scale, this technology could be used to heat buildings. As one would imagine, this would save people tons of money, and in the long run, have a profound effect on electric energy companies. Many uses are still being theorized and developed, but skeptics are worried about a key component of the process that might bring work to a stand still.

Benzene can be a nasty substance with bad effects on the human body. You may know it best as one of the carcinogens present in Tobacco smoke. In addition to its potential to cause cancer, Benzene can also disrupt blood cell counts, cause Leukemia and is highly flammable. That being said, the human body is exposed to low levels of benzene every day at gas stations, as well as through glue, paint, furniture wax, and laundry detergent. Don’t worry just yet though, as the tech is still 10-20 years off in making this process a commercial option. Hopefully by then, all that nastiness will be worked out.
