Coal enters rehab

(Dec. 7, 2007) Coal, chock-full of substances of known toxicity, epitomizes dirty fuel. The perils in coal burning – and this is an abbreviated list – include fly ash and heavy metals such as arsenic, lead, mercury, sulphur., vanadium, beryllium, cadmium, barium, chromium, molybdenum, zinc, selenium, radium, uranium and thorium. If these substances and their byproducts are not controlled in coal burning, to keep emissions within safe levels, human health and the environment can suffer. Continue reading

Hydrogen: Running energy policy on hype

Californian Sam Leach knew that hydrogen was a winner. Near the time of the first Middle East Oil crisis in the early 1970s, Leach convinced gullible American investors to give him US$1-million on the strength of his claim that he had built a car that used ordinary water as a fuel. His "invention" used electrolysis assisted by his secret catalyst. He claimed to be able to decompose water into oxygen and hydrogen, and then use the hydrogen as a fuel to run the engine and generate more electricity than he started with. The claims turned out to be false, but by then Leach and the money had moved on. Continue reading

LEDs signal energy revolution

While governments have diddled for decades in the energy marketplace, subsidizing a 500-megawatt nuclear plant here, a 5,000-kilometre Arctic pipeline there, the big energy gains have come via pint-sized innovations in conservation and energy-efficiency. This decade, the biggest little gainers on the planet are LEDs, or light-emitting diodes, those gizmos that first entered the public consciousness in the 1970s through calculators and digital watches.

Blown over

(February 22, 2007) Last month, the Conservative government joined the long line of governments around the world subsidizing the production of wind power. Meanwhile, new information about wind power from Europe raises the spectre of unexpected blackout risks, high costs, unreliable production and even questionable environmental benefits.
