These genes allow Pichia to use methanol as a carbon and energy source.

Every race from 1965 forward has been run using methanol or ethanol based fuels.

Alpha-carbonic acid was prepared by the same technique using methanol rather than water as a solvent.

And some forms of racing, like Indy cars, use methanol, which comes from plant matter.

The company is also making new fuel cells that use methanol to run laptop computers far longer than conventional batteries do.

However, for fuel cells it shows only emissions from using hydrogen gas, natural gas and methanol.

This is harder and less efficient than using methanol, but gasoline is universally available.

Catalytic Converters Some cars will achieve the standards by using natural gas or methanol.

Champ Cars use methanol for fuel rather than gasoline, and refuelling has always been permitted during the race.

Some, like Ford, are sticking with hydrogen gas in tanks, while others use liquid methanol.
