All the clean energy you need
Future tense: How a solar-hydrogen economy could provide us with all the energy we need

What one energy source has the ability to – in the long term – supply the people of the world with all of the energy they need in an reliable and renewable manner? According to Derek Abbott, professor of electrical engineering at the University of Adelaide in Australia, there is only one possible answer: solar-hydrogen.
Solar-hydrogen means using solar power to generate electricity and then using the electricity to electrolyze water to generate hydrogen when necessary – for example, to run automobiles on hydrogen power. Abbott believes that solar-hydrogen could one day produce about 70 percent of the world's energy requirements, and he's done some math over on PhysOrg that he says proves him right. The short version: the solar energy that hits the earth (and is not reflected or absorbed by clouds) is "more than 5,000 times our present global energy consumption."
Aside from the sustainability angle, solar-hydrogen beats all other energy sources on economic grounds, Abott believes. His preferred method of capturing the energy of the sun is solar thermal collectors. Here's how he thinks it'll work in the coming decades:
Governments should begin by setting up sizable solar farms that supplement existing grid electricity and provide enough hydrogen to power buses. Enthusiasts will then buy hydrogen cars, retrofit existing cars, and refuel at bus depots. Then things will grow from there. You gotta start somewhere.
Abbott's other reasons for choosing H2 over battery-powered electrics include: fewer chemicals and toxic waste due to lack of batteries and that "gasoline combustion engines can be retrofitted to run on hydrogen, and the car manufacturing industry has infrastructure tailored to combustion technology." Hmm, maybe he should read Greenlings.

This would be a huge step in the right direction. Actually using technology for the betterment of mankind might not make as much money as indentured servitude under black gold, but it'll leave a better place for the grandkids to come up in.

Speaking of Aussies revolutionizing the way we harness energy..... here's something we should all keep our eyes on too.....
...Perhaps someone ought to send this video above to Obama and tell him to stop being a fuking dumbass and pretending like we're all idiots, and to realize that we have multiple different technologies already available. In turn, instead of wasting so much god damn money over seas, we should be using tax payer dollars towards producing likewise technology instead of lying to the world about 'man made' global warming... and while there's no actual scientific consensus.... you have the media screaming, "oh lets everyone pay our carbon tax's!" .... oh and then I love this one... Al Gore (fraud)... were you aware that Al Gore wants us to buy our carbon indulgences FROM HIS COMPANY!? So not only is he holding seminars teaching certain CEO's of certain company's on how to persuade the American public (and the world) into accepting the MYTH that man created global warming, but he's also on the board of directors for a company who will be buying cap and trade interests...not to mention the $6 million he's invested in a software company that stands to make billions of dollars from cap-and-trade regulation.
