Comments on: Bacteria Discovered To Convert Sugar Directly Into Electricity http://www.sciscoop.com/2003-9-8-64458-19223.html Scooping up science news and dropping it on your desk Wed, 10 Mar 2010 05:31:43 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: InelRum http://www.sciscoop.com/2003-9-8-64458-19223.html/comment-page-1#comment-3435 InelRum Fri, 24 Oct 2003 19:39:00 +0000 http://localhost/~arielschwartz/wordpress/sciscoop/?p=1592#comment-3435 Sure, the current method is more economical, but what will we do in 2046, the estimated time when ALL the earth's petroleum will run out. Why do you think so many companies are investing in an alternate source of energy, that's simply easy to understand, EVENTUALLY WE'RE GOING TO RUN OUT OF THE ONLY SOURCE OF ENERGY WE ACTUALLY HAVE!!! So lets start looking for another one now, while there's still time. Think About It.

These are also present in organic waste as sugar-like compounds. The idea is to use fuels that are essentially free where cost is important. Alternatively, special applications like cell phones or remote military stuff could use a special fuel where cost is secondary. The microbe uses the carbon, oxygen and hydrogen for its process.

Your comment sure got me thinking though I apologise for the Horrid grammar and spelling. English is not my favorite language.

sugar to produce 1Kwh: 1 cup = .47lb
price of sugar (US, retail) = $.43
   (EU about 1.5X this)
sugar cost of 1Kwh bio-electricity = $.20
‘current’ price of 1Kwh (US, retail, nominal)
    = $.084

So this is 2.4X as expensive as commercially produced power.

NB: In Cuba, the low cost of sugar would make this form of energy competative.
