I know that's a wind-up press release but liquid natural gas engines already exist, and i remember watching an episode of Top Gear a few years ago where they tested a standard petrol car, a car running on LNG from cow pats, and one running on LNG made from human waste in a drag race (well it is top gear).
Petrol creamed the gas ones, but cow beat human, probably a youtube clip of it somewhere.

This hp2g bull****, doesn't america have a department that investigates false or misleading advertising?
If this guy tried to sell it in the UK the advertising standards agency and the office of fair trading would be on his ass.
