Don't eat your spinach. Put it on your solar panel instead.
OK, that's not actually advisable. However, it is true that the latest attempt to put photosynthesis to work to produce electricity finds researchers at Vanderbilt University reporting big gains with a new concept that uses a protein found in spinach in combination with carefully formatted silicon.
The research at Vanderbilt uses a specific protein involved in photosynthesis called photosystem 1, which was discovered 40 years ago and apparently quickly seduced solar researchers with its ability to convert sunlight into electrical energy with nearly 100 percent efficiency, according to Vanderbilt.
That the stuff is cheap and plentiful – it can be extracted from the rapidly growing kudzu vine, not just 99-cents-a-bunch spinach – compared to common microelectronic materials only increased the lure, according to Vanderbilt.
