In most fuel cells it is the hydrogen that the oxygen is looking for not the carbon, which is not to say that carbon dioxide is not created but to question how the electrons are obtained in this reaction
I was amazed with the news that I?ve heard last night about Bloom Energy. Bloom energy is on of the new form of alternative energy. They are proponents of fuel cell technology, and thus far they have established energy servers at eBay and Google campuses, and they are capable of producing energy at a cost of only 8 to 9 cents per kilowatt hour. One energy server is certainly out of the scope of payday loans, or most bank loans for that matter ? each server costs up to $900,000 a piece, and produces up to 100 KWe, enough to power a small office building or about 100 homes, but that doesn't include fuel.
Did you not read that this technology is 2x as efficient? Meaning that for each gram of CO2 produced by this technology, 2 grams of CO2 are taken out of the air which are presently produced by current technology, which would be replaced? Most current technology electricity generation employs generators, powered by oil, gas, coal etc., producing CO2. We would be cutting CO2 production by 50%!
The next step would be all electric cars using fuel cells. The efficiency improvement on those would be substancially more than 2X!
Yes, we are on the right track!
Is this really the whole story? What is happening the the H? Natural gas is mostly Methane CH4. I thought that the usual fuel cell implementations use the H and end up with H2O as the byproduct. Surely they are not wasting the Hydrogen.
Well that is terrific - ONLY ONE LITTLE CATCH.. if you call this thing Green Technology... ISN'T CO2 the thing we are trying to eliminate and yet this box emits CO2 ...Hmmm how about telling me 2x efficiency with either pure O or H2O as a waste product. although that CO2 in the Atmosphere - oh that is right we are going to bury it in the sand.. Brilliant - transfer the problem from one place to another..
NOT GREEN, except maybe the trees will love it...
So Bloom Energy has made some prototypes of a really, really expensive power generator. They claim they will reduce the cost by orders of magnitude in 5-10 years.
I don't think anybody knows what breakthroughs in a new technology will be made in 5-10 years, so this all sounds like speculation to me.
We are just going to have to wait 5-10 years and see what they come up with.
