• Any alternative fuel must have nutrients to feed whatever organic source of oil is being used.
  
  However, on a large scale, I%26#039;ll guarantee that the preferred nutrition for biodiesel will be sewage in the future and with that biodiesel will be the only fuel used.
  
  The effluent, after solids are removed from the wastewater, is full of nutrition and by pulling it off the treatment process the need for purifying the stream is reduced, the oil from the algae or bacteria removes the nutrients and also binds the heavy metals and pollutants.
  
  The oil will be sold at a profit and the effluent from the biofuel farm can be treated cheaply to become drinking water again, also worth a lot of money yet more than that it will conserve billions of gallons of daily water demand from fresh water sources.
  
  Keep in mind that North Lake Tahoe has been using a completely recycled water system since the 1970%26#039;s. Their system uses expensive processes to remove suspended solids and chemicals from the wastewater, flocculates are used to precipitate out the heavy metals and pollutants.
  
  If every wasterwater treatment plant in the world did this, the volume of production can handle the demand. The resource grows with population, is considered useless and for sure isn%26#039;t a food at your grocery store.
  
  No fertilizer, no pesticides, no petroleum required, just people and animals producing tons of waste daily being put to use instead of %26quot;treated%26quot; and released back into the world.
  
  Right now every major power resource wastes twice as much energy to heat loss as is delivered as power, so a 1,000 megawatt nuclear power plant puts 2,000 megawatts into heating up the world when it has to cool the water from 800-deg steam back to a fluid.

• Right now one might wish one could get a TDI rabbit or one of the other turbo diesels from Europe or China for current use. But Volkswagen has a new 2 seater (one before the other) that can deliver 235 mpg on diesel fuel, due for introduction in 2010, likely just in Europe.
  
  I think that electric with EESU power storage and solar charging may be our next step.
  EESU will allow us to have recharges in minutes and range as much as 100 km being economical, with very low weight.
  
  Carbon fibre body is also a likely direction. 0% 0 Votes
• Well, I drive cars that run on natural gas (methane) right now - I couldn%26#039;t wait for other technologies to catch on or be developed. Ford made mine back in 1999 and 2000, so they%26#039;ve been around for a while, but most people don%26#039;t know about them. It costs me $10 to fill up, and they run way cleaner than any other vehicle out there that actually exists. Plus, the USA has lots of its own supply of natural gas, so the money stays in our own economy. Lots of upside to this. Check out my sources to learn more about these cars, and find out if there are filling stations near you. Good luck! www.NGVamerica.org

• What I think is going to happen is that in about 8 or so years, hybrids will be all people have and the amount of hybrid cars there are now, will be the amount of electric cars there are then. Electric cars will be the most energy efficient and I think it will help a lot for our environment. 0% 0 Votes
• Ethanol and hydrogen(via ammonia).
  I say hydrogen via ammonia because
  - ammonia can refuel a practical hydrogen station.
  - ammonia from WIND can be really cheap... 0% 0 Votes
• If I was you, I%26#039;d just buy a Brown%26#039;s gas generator and the cheapest car you can stand for now.
  
  That way you%26#039;ll be getting semi-okay (depending on your car) mileage until the real stuff comes out... 0% 0 Votes
• They are all wrong for the environmentalist nuts, as they all produce the same CO2 .. The energy comes from burning C and it will produce the same energy regardless of what U burn... 0% 0 Votes
• What difference does it make, there will be no oil for us.
