[DML] Re: Alternate Fuels..



A major reason any other fuel looks better pricewise is because it is not as heavily taxed as gasoline (or diesel). While you can consider some fuels "free" the conversion is not. It has to be amortized over the life of the vehicle. Depending on the amount of miles driven that can take a while. In some cases more than the life of any single vehicle. This does not consider most conversions will still also use gasoline (dual fuel) or you have a severely reduced operating range. Yes, the sun and wind are free, the catch is in collecting, storing, and transferring sufficient quantities to power a vehicle. Very difficult to compete against mature technologies with a large infrastructure. To be successful you must have a competitor vehicle with at least similar operating characteristics. That means a range of at least 250 miles, fast and plentiful stations to refill/recharge (minutes not hours) and enough performance to drive on the highway. Other secondary issues include availability of service, and at least close in cost. My guess is you will see cars with "reformers" onboard to convert gasoline into Methane or Hydrogen. At first that will run the IC motor in hybrids. Eventually it will run a fuel cell. We will still be using gasoline, just a LOT more efficiently for the near future.
