"Capturing sunlight to make enough hydrogen fuel to power cars and buildings has been brought a step closer by a British research company.
Hydrogen Solar says it has managed to convert more than 8% of sunlight directly into hydrogen with fuel cell technology it has specially developed. For an energy source to be commercially viable, it must reach an efficiency of 10%, which is an industry standard.
Hydrogen power, a renewable energy, has the potential to replace fossil fuels...The Tandem Cell technology developed by Hydrogen Solar uses two photocatalytic cells in series which are coated with a nano-crystalline - extremely thin - metal oxide film. The key to the process has been the advances in novel coatings brought about by recent developments in nanotechnology."
Although its potential has been discussed for decades, advances in nanotechnology are helping to make the promise of hydrogen power more feasible.
......
Last year, General Motors (GM) said it planned to be the first to sell a million fuel cell vehicles in the next decade.
Other automotive giants have also championed hydrogen fuel.
DaimlerChrysler, Ford and GM have spent about $2bn on fuel cell cars, trucks and buses. The first products came out last year, and many UK cities have deployed hydrogen buses.
Ford's Chairman William Clay Ford Jr went so far as predicting fuel cells would end the reign of the internal combustion engine.
But there have been a number of technical and financial stumbling blocks - including taxation - which have prevented its large scale adoption, and Dr Auty thinks there need to be more political will to push the technology forward.
"There is a chicken and egg issue here," he said.
"Who is going to build a car before they have filling stations, and who is going to build stations before we have the cars. "It has to be strategically thought out and driven by government. There is a political will in US, but I think the UK is a bit behind the pace."
Crude oil, which rose above $US46 a barrel on the weekend, may fall to $US30 a barrel next year as concerns about supply disruptions in Iraq, Russia and Venezuela ease and the Organisation of Petroleum Exporting Countries boosts output.
Speaking in Jakarta, OPEC president Purnomo Yusgiantoro said: "There is a psychological premium in the market of $US16 a barrel because of Yukos, Iraq and Venezuela. If the premium disappears, the crude oil price will stay at about $US30 a barrel next year."
.....
Venezuela, Iraq and Russia supply about 17 per cent of the world's crude oil.
OPEC was pumping 30 million barrels of crude oil a day to stem the rally in prices, Mr Purnomo said. The increase had nothing to do with a shortage of oil.
"The world is already oversupplied by between 1.5 and 2 million barrels a day but the price is still high," he said.
Source: SMH - http://www.smh.com.au/articles/2004/08/20/1092972754647.htmlThe first three oil shocks were supply shocks initiated by the OPEC export cartel and prompted by revolutions and wars (the Yom Kippur war in 1973, the Iranian revolution and the Iraq-Iran war of 1979-80, and the first Gulf War of 1990).
The fourth, this one, is primarily a demand shock led by China. As an example: in the Yangtze River Delta there are three to four power cuts a week because the electricity industry is unable to cope with the explosion in manufacturing. More and more factories are therefore running on diesel generators instead; as a result demand for fuel is exploding.
All this makes the current oil shock different in character, but perhaps not in effect.
The first three oil shocks each helped cause global recession. The 2004 version might not do that because oil is a smaller proportion of the world economy and because China's explosive demand for energy and other raw materials is based on high consumer demand for cheap Chinese manufactures.
China thus demonstrates the truism that labour is a far greater proportion of the end price of a manufactured product than the raw material, so that cheap labour outweighs the impact of the commodity price shock.
As a result, end prices are not rising and central banks will not have to create recessions to retrench demand and control inflation as before. Then again, rates are rising and the US economy looks more vulnerable than it ever has to any kind of shock, given the lack of savings, and the record current account deficit and federal budget deficit.

Hearing prices of $1 per litre makes me envious, even though I know that`s quite expensive for Oz.... it`s a hell of alot cheaper than here.

Whinge. Whinge. Whinge.
This may come as a shock to some of you, but there are people in this wide brown land of ours who have been paying well over $1 per litre of fuel for years.
Such as at Menindee where I am reliably informed that the going rate is currently $1.15 per litre.
Are we really a forum of city slickers who have never been west of the divide?
