In the 1950s, Russian and American scientists knew there was no limit to the power of thermonuclear hydrogen bombs.

Since different sorts of living tissue contain different amounts of hydrogen, the application of sufficient computing power to the signal can turn it into a clear image of the body's interior.
In terms of producing hydrogen to power a car, the unit can make enough gas overnight to provide fuel for 25 miles.
In August, Bush signed an energy bill laden with special business-tax breaks for new nuclear power facilities, "clean coal" technology, coal mined from Native American lands, refinery expansion, fuel-cell power plants, hydrogen refueling stations and for producers of energy-efficient appliances, commercial buildings and homes.
The power output is small, orders of magnitude lower than from hydrogen or methanol fuel cells, but the supply and handling of these flammable fuels is avoided.
Heartening news rang forth from the renewable energy sector this week as a UN-backed study reported that the building of new renewable energy plants has officially overtaken fossil fuel plants in Europe and the US. We also took a look at two brand new types of power plants -- the world's first hydrogen-driven power plant in Italy and the first hybrid coal-solar power plant in Colorado.

Intelligent Energy is a global clean power systems company, with a range of leading fuel cell and hydrogen generation technologies.

Some even dream of using natural gas to make hydrogen which would power fuel-cell cars, though advocates admit that these are still a long way off.

Also, since the necessarily erratic nature of wind power necessitates the development of energy-storage technologies to guarantee continuous supply, wind power can also act as a spur to the development of a hydrogen economy in which cars no longer require petroleum fuel.
It is these types of massive political and social upheavals, more than the eventual greening of global energy production, that will ensure that hydrogen power would indeed change the world.
Though it appears to all intents and purposes like a state-of-the-art power station, FutureGen is actually a huge hydrogen production facility in disguise.
Wrightbus is working with the ISE Corporation of California to deliver the new buses in which hydrogen is used to power an electric drive system.
The newspapers were full of articles on solar power, fusion and converting the economy to run on fuel cells and hydrogen.
ECONOMIST: A fundamental change is coming sooner than you might think
From the beginning, the cloud hanging over the whole hydrogen enterprise has not been the power source as such, but the intractable difficulty of distributing and storing the stuff.
Nuclear plant operators are battling to prevent meltdowns at three reactors, and Chief Cabinet Secretary Yukio Edano warned Sunday that a hydrogen explosion could occur at Unit 3 of the Fukushima No.1 nuclear power station.

Proponents of a hydrogen economy want to produce the hydrogen with excess electricity from renewables such as wind power and solar energy.
The basic idea, as is done here, of using sunlight through solar PV to electrolyse water, store the hydrogen then, when the power is required, reverse the process.
Unlike the batteries in traditional arms, which die quickly, a small canister of hydrogen peroxide concealed in the arm can last up to 18 hours, and provides about the same power and functionality of a human arm.
