MIT creates solar cell from grass clippings

MrSeb (471333) writes | more than 2 years ago

Power 1

MrSeb writes "A researcher at MIT, Andreas Mershin, has created solar panels from agricultural waste such as cut grass and dead leaves. In a few years, Mershin says it’ll be possible to stir some grass clippings into a bag of cheap chemicals, paint the mixture on your roof, and immediately start producing electricity. If you remember high school biology classes, you will hopefully remember a process called photosynthesis, whereby plants turn sunlight into energy. Mershin has found a process which extracts the photosynthesizing molecules, called photosystem I, from plant matter. Photosystem I contains chlorophyll, the protein that actually converts photons into a flow of electrons. These molecules are then stabilized, sloshed onto a piece of treated glass, and voila: solar power from grass clippings."

Nothing to see here -- keep moving.

Seriously, the costs of the "specially treated glass" will probably exceed the costs of most of the alternatives. And what kind of a usable life can we hope to get from this? Will we have to clean it and recoat it every month?

An interesting academic exercise, but not much more. Let's try news on something practical.
