whisper tech, page-3

Its a combustion engine not a fuel cell, no comparison in the technologies. Maybe I'm reading it wrong , but I don't see how they are comparing the Combustion engine product with ceres power , who are developing fuel cells. Maybe Ceres Power are developing CHP Combustion engines aswell???
Either way different technology to CFU and I am sure alot less efficient.
If I recall an article a bit more than 12 months ago, VW were thinking of manufacturing the same thing but on a larger scale.
