OT but cool: New Fuel Cell coming out in 2014

From: Rod-Lists 
New 25 Kw fuel cell tech that is claiming 80% efficiency in a co-generation setup.
They claim they dropped the temperature down to 300 degrees and it is the size of a dishwasher.

Currently runs on methane but could do hydrogen.

=============================================================== From: Stephen Kraus ------------------------------------------------------ I don't know, I don't want anything generating hydrogen in that amount near my house. Diesel and biodiesel for me thanks. 80% efficiency seems a bit on the high side too, and theres been setups claiming efficiency like this that were found to be overstated in the past.

=============================================================== From: Rod-Lists ------------------------------------------------------ It doesn't generate H or methane, it breaks it down. ----- Original Message -----

=============================================================== From: Stephen Kraus ------------------------------------------------------ Breaking it down implies Hydrogen, either way 80% is either impressive or bullshit as far as the law of thermodynamics

If I understand fuel cells correctly, they output water. So they're generating H2O. Dan

=============================================================== From: Rod-Lists ------------------------------------------------------ Stephen that is only in a co-generation configuration in which they are capturing the heat of the system and putting it to work. I think every generating system should be co-generation but doesn't always happen. I also wondered about coupling geothermal to thermoelectric systems or stirling engines to generate electricity thus getting co-gerneration from the other direction. ----- Original Message -----

=============================================================== From: Stephen Kraus ------------------------------------------------------ Stirling engines are incredibly weak as far as actual torque generated and work done, most of the actual uses of stirling engines are as heat pumps where it obviously makes sense to use them. Either way, I remaining skeptical of this for now, mainly because 80% efficiency seems incredibly high...especially for power generation.

=============================================================== From: Aaron Welch ------------------------------------------------------ Industrial scale cogeneration on manufacturing exhaust would be awesome. If you take waste heat from a process and use it to create or offset the need for power on the input side a business could save millions per year not to mention lowering their carbon footprint. -AW

=============================================================== From: Stephen Kraus ------------------------------------------------------ That seems incredibly valid and useful.
