Biological solar electric

Some clever sorts have made a working solar panel, using moss to do all the hard work.

Its extremely early days. They've tapped 0.1% of the electricity that is generated as a by-product of photosynthesis, but it worked.

I get excited by things like this. This is working with nature to meet our modern day technology needs. It will be nothing more than a gimmick for a good few years yet, but then when I went to school 'conventional' photovoltaic solar power was no good for anything beyond powering a pocket calculator, and now look where we're at.

Wont it be great if we end up with green roofs that insulate well, muffle noise, trap particulates from the air, hold rainwater, produce oxygen, heal themselves, and generate power all at the same time

 

Now that is green power.

 

They say in the article that almost any plants could be used.
Admittedly I didn't read the whole article in great detail so don't know if it was mentioned, but this brings up the possibility of using grassed sports fields to generate electricity.
