Could we harness electricity from chloroplasts?
« on: 21/05/2015 12:50:02 »
Parikshit asked the Naked Scientists:
   
Could we harness electricity the power of chloroplasts and photo systems 1 & 2?

What do you think?

Saw this in "Stanford news"...

Stanford engineers have generated electrical current by tapping into the electron activity in individual algae cells. Photosynthesis excites electrons, which can then be turned into an electrical current using a specially designed gold electrode. This study could be the first step toward carbon-free electricity directly from plants.

I volunteer not to be the person inserting gold electrodes into chloroplasts!

You can light a LED for several days using a boiled potato.

See it done here...


It comes out of the Nernst equation which is discussed here (but the last time I used the Nernst eq., I had a slide rule)

How many potato batteries would it take to boil a potato?
