Jack Nicholson's 1978 Hydrogen Powered Car

"The Great Global Warming Swindle" is a Swindle

The film's key contention was that the increase in atmospheric temperatures observed since the 1970s was not primarily caused by emissions of greenhouse gases from burning fossil fuels.

First aired by Channel 4 in March 2007, the documentary has since reportedly been sold to 21 countries and distributed on DVD.

Dr Wunsch, from the Massachussetts Institute of Technology, said he believed he was being asked to take part in a programme that would "discuss in a balanced way the complicated elements of understanding of climate change", but "what we now have is an out-and-out propaganda piece, in which there is not even a gesture toward balance".

The Broadcasting Code requires Channel 4 to show "due impartiality" on "matters of major political and industrial controversy and major matters relating to current public policy".

The last segment of the programme, dealing with the politics of climate change, broke this obligation, Ofcom judged, and did not reflect a range of views, as required under the code.

Dyeing to Boost Solar Efficiency by 50%

MIT has perfected a dye technology that could change the solar world as we know it.

The most efficient form of solar technology today is (arguably) extreme concentrated photovoltaics, essentially solar panels placed under a magnifying glass. But the problem with these systems is heat.

Concentrated sunlight can melt silicon solar panels unless you include specialized cooling systems. Cooling technology costs money, and the panels require expensive tracking mechanisms to follow the sun through the day. MIT’s new solar system bypasses the heat and tracking problems all together.

Thin coatings of organic dyes absorb sunlight and redirect favored wavelengths into a pane of glass. The light is aimed and concentrated towards the edge of the pane where small solar panels are located. The concentrated light allows the panels to produce the maximum possible amount of energy all day, every day without cooling systems or complex tracking mechanisms.

“In addition, the focused light increases the electrical power obtained from each solar cell “by a factor of over 40.”" According to Marc A Baldo, an associate professor at MIT who helped lead the project. For more technical details, you may need an AAAS membership to read the Science article.
Three Reasons Why This Could Rock the Solar World:

1) It’s Easy: The technology is neither complex or difficult to manufacture.
2) Upgrade Existing Solar
3) It’s Coming Soon: MIT claims this technology could be ready for commercial production within three years.

200mph electric car able to zip along a monorail

This working prototype was built for a mere $2500, and spends most of its life as an ultralight 3-wheeled electric runabout. But if its inventors Jay Andress and Andy Webster can raise $10 million, they’re going to create a one-mile test monorail that hooks up to those wheels on the car’s roof.

While riding the electric rails, the car can accelerate to 200mph, and charge its batteries as it goes. All the while, the driver can relax and leave the driving to the computers and rails. Then, once the monorail section of the trip gets the car close to its destination, it can drive the rest of the way under its own freshly charged electric power.

The biggest catch is building the $500 billion worth of rails to accommodate a country full of such vehicles riding along the corridors of Interstate highways. But its developers say the system could pay for itself in energy savings in a year.

Japanese sailor first to cross Pacific in wave-powered boat

Japanese sailor and environmentalist Kenichi Horie has completed a 110-day solo voyage across the Pacific Ocean in a boat propelled by wave power to claim another world first.
Weak waves and opposing ocean currents delayed his arrival, which was originally set for late May.

"When waves were weak, the boat slowed down. That's the problem to be solved," the adventurer told reporters Saturday from aboard his catamaran Suntory Mermaid II off the Kii Peninsula in western Japan.

The 9.5 metre (31-foot) boat is equipped with two special fins at the front which can move like a dolphin's tail each time the vessel rises or falls with the rhythm of the waves.

Horie, who will turn 70 in September, reached his destination in the channel between the main Japanese islands of Honshu and Shikoku just before midnight (1500 GMT Friday) after covering some 7,000 kilometres (3,780 nautical miles) from Hawaii without a port call.

National speed limit pushed as gas saver

An influential Republican senator suggested Thursday that Congress might want to consider reimposing a national speed limit to save gasoline and possibly ease fuel prices.

Sen. John Warner, R-Virginia, asked Energy Secretary Samuel Bodman to look into what speed limit would provide optimum gasoline efficiency given current technology. He said he wants to know if the administration might support efforts in Congress to require a lower speed limit.

Congress in 1974 set a national 55 mph speed limit because of energy shortages caused by the Arab oil embargo. The speed limit was repealed in 1995 when crude oil dipped to $17 a barrel and gasoline cost $1.10 a gallon.

As motorists headed on trips for this Fourth of July weekend, gasoline averaged $4.10 a gallon nationwide, with oil hovering around $145 a barrel.

Warner cited studies that showed the 55 mph speed limit saved 167,000 barrels of oil a day, or 2 percent of the country's highway fuel consumption, while avoiding up to 4,000 traffic deaths a year.

"Given the significant increase in the number of vehicles on America's highway system from 1974 to 2008, one could assume that the amount of fuel that could be conserved today is far greater," Warner wrote Bodman.

Warner asked the department to determine at what speeds vehicles would be most fuel efficient, how much fuel savings would be achieved, and whether it would be reasonable to assume there would be a reduction in prices at the pump if the speed limit were lowered.

Toyota to add solar panels to Prius hybrid

Toyota Motor Corp plans to install solar panels on its next-generation Prius hybrid cars, becoming the first major automaker to use solar power for a vehicle, the Nikkei business daily reported on Monday.

The paper said Toyota would equip solar panels on the roof of the high-end version of the Prius when it redesigns the gasoline-electric hybrid car early next year, and the power generated by the system would be used for the air conditioning.

Toyota plans to use solar panels made by Kyocera Corp (6971.T: Quote, Profile, Research, Stock Buzz), the Nikkei said.
