Ford’s experimental hydrogen-powered shuttle bus is powered by H2ICE, “Hydrogen Internal Combustion Engine”:
A Hydrogen Internal Combustion Engine (H2ICE) is a traditional internal combustion engine that is modified to run on hydrogen, rather than gasoline. Compared with today’s gasoline engines, H2ICE delivers up to a 99.7 percent reduction in CO2 and includes many of the benefits of a hydrogen fuel cell, but at a fraction of the cost.
High-school physics instructor Cory Waxman of Phoenix, Arizona, led a team of students in building a solar-powered H2ICE truck. It requires no external source of hydrogen; an electrolysis unit in the bed extracts hydrogen from tap water. More info: 1, 2, and videos. [Thanks to Joe Stump for the tip.]
Pegasus is a 3000 horsepower Land Speed Record vehicle:
The Pegasus Team’s main focus is designing, building and developing the world’s fastest environmentally friendly car. Our aim is to be the first team to reach 500mph with a wheel-driven car powered by a low-emission hybrid-electric propulsion system. The Pegasus Car will run on clean fuels including Natural Gas and unleaded fuels and features an innovative gas turbine engine / high-speed electrical generator system.
And, it would look great in my driveway. [Thanks to Bim for the tip.]
