    So a decade or two based on your estimate, will still put it within this lifetime.

    We cannot pre-empt technological breakthroughs. They once said that 1 ton of pure metal cannot possibly fly in the air, right?

    Hyrdrogen will be viable if the dependence on traditional power sources will decrease.

    Right now, the use of Nuclear power is the only solution to make Hyrdogen fuel fly.

    The problem with a hydrogen economy is that it's a false economy... it's based on the premise of hydrogen being available in fuel form already... the amount of processing required to create hydrogen is comparable to us having to actually create synthetic oil (though not as expensive). Like mbt says, hydrogen production will still rely on other sources of energy.

    Biofuels, on the other hand, require less processing and benefit from greenhouse gas conservation... in other words, the amount of CO2 that burning biofuels produces is reabsorbed in the creation of these biofuels.

    And hydrogen storage is not impossible, it's just very expensive. And it depends on materials development, as current hydrogen storage matrices are either toxic or exotic materials. I'm not hoping for much. Look at superconductors. Over two decades and we still aren't any closer to a commercially viable room temperature superconductor. How about solar cells? In development for over three or four decades, and economically feasible large scale solar arrays are still many years away.

    Ang pagbalik ng comeback...

    palagay ko tatagal pa ang paggamit ng petroleum based fuels. The trend in engine design is to make engines more fuel efficient, remember na hindi na-mamaximize yung potential energy ng petro fuel in our existing engines, 30% or 40% effieciency lang yata for diesel engines, less for gasoline. alternative fuels may get in the picture but it's not going to substitute petroleum based fuels totally. masyado labor intensive ang pag-ani ng vegetable crops and turn around time for crops is not that fast. depende na lang siguro kung maka imbento sila ng ibang engine design na hindi masyado nag-rerely sa fuel combustion (e.g., anti gravity, or ion propulsion. medyso scifi masyado hehehe pero who knows, think-out-of-box kumbaga). a hundred years ago, man never imagined a flying vehicle that can break the speed of sound, or a land-based vehicle that can run more than 100 mph. it's really up to man's inventive genius. ;)

    interesting. sana it's not too late to have feasible alternative fuel.

    or gagawa na lang ako ng minovsky reactor from gundam or a fusion reactor from battletech. hahahaha.

    meron daw nadiscover ang china/japan na malaking reserve ng oil &/or gas sa east china sea. china have begun drilling and pumping at that location to the strong protest of japan. both countries claim that the area belongs to their Exclusive Economic Zone. some chinese newspapers say that the oil or gas reserves in that area ay mas malaki pa daw kesa sa reserves ng saudi arabia.

    problema yan... pag puro hanap ng hanap ng bagong oil deposits, paurong ng paurong yung paghanap ng makabagong fuel kasi nawawala yung urgency

Is oil nearing its end or is it here to stay?
