why not ditch hybrid / hydrogen hybrid and just go electrical?
again, watch "who killed the electric car" available from all good P2P sites

my view from the very start. its only carbon neutral if there was no refining no chemical fertilization i think someone also did the math on the land area that would be required........... sorry, formula does not balance. from someone that has made just 15L of ethanol i can tell you that it useds about 4kg of propane to do.............then there was the CO2 released by fermentation....................... and my starting components were refined sugar.............. |

heh my view exactly. on a large scale it's not quite so bad, but it's still terrible. bio diesels aren't much better either. why even bother with the combustion engine. focus energies on electric cars. superior to combustion in everyway except distance, which i'd like to see solved by super capacitors. drive through recharge and no need to dispose of them once a year like batteries. less weight as well |

I think this, and other reports like it, suffer from myopia. The point is really not to have one new technology that is a magic bullet to replace cheap hydrocarbons. Secure energy supplies can only be obtained from a diversity of sources, so there is no single point of failure. So biofuels, wind, geothermal, solar, the new nano-antannae currently being hyped, hydro, others I'm forgetting/don't know of, and even classical gas and hydrocarbon production all have a part to play in the future. With that said, it has always been my view that the strength of bio fuels is the waste products of other processes. Almost any product that was once a plant or an animals can be converted into some kind of bio fuel. |

The best way to produce biofuel is with sea phytoplankton. Up to 60-80% of pure oil per kilo on a 1/50th of the land surface. And useable in factory chimneys to extract CO² from the outgoing gases. The thing is to have low consumption equipement more than finding a way to continue the wastes by excess that we do now, when we can divide by ten the energy input needed for anythnig with the technologies that we already have. Spacecrafts are the most efficient things made by men, except the carb they need to take off. |
