Ady Gil, formerly Earthrace, joins Sea Shepherd fleet

Thanks to a $1 million donation from its namesake, US multi-millionaire Ady Gil, formerly known as Earthrace, the Ady Gil has become the latest addition to the Sea Shepherd Conservation Society's protest fleet. The Ady Gil will bear down on whalers at 40 knots, blaring Maori-inspired war cries through a 9000W speaker system. "They're going to think 'what the f..k have we got here?' " laughed Ady Gil's skipper Pete Bethune.

"It deflects radar signals, so it's very hard for radar systems to pick us up. It's effectively a stealth boat. Made of carbon, with carbon flecks in the paint you can have a big boat with a 20kW radar 400m away and they won't see you. In the past, the Steve Irwin has only been fast enough to keep up with the processing ship, the Nissan Maru, but not the harpooners. We can keep up with the harpoon vessels.” "The point of conflict will shift to include the harpoon vessels now, so it gives us a chance to stop the whales being harpooned." The boat holds the world record for the fastest circumnavigation of the globe.  read more »

The leading cars in this year’s Global Green Challenge solar car race have passed the halfway point in their epic 1,864-mile (3,000-kilometre) race across some of Australia's harshest terrain from Darwin to Adelaide.

The Global Green Challenge - an evolution of the acclaimed World Solar Challenge - is the world's leading, cross-continental showcase of the latest advances in hybrid, electric, solar, low emission, and alternative energy vehicles. The race, which is now in its tenth year, was pioneered by the South Australian Tourism Commission and aims to highlight the latest advances in hybrid, electric, solar and alternative energy vehicles.  read more »

"Tourist Trophy eXtreme Grand Prix". TTXGP is not a motorcycle race but the motorcycle race: the first, the most famous, and by far the deadliest. So it's all the more surprising that in the week before the race, a dark horse emerges, freaking out all the factory teams. The fastest bike in the TTXGP prelims - two qualifying runs around the island - turns out to be from Team Agni, a total unknown, a mere privateer. Millions of American research-and-development dollars find themselves chasing the tail of a no-money ratbike engineered in India. Cedric Lynch’s first electrical motor was made from flattened soup cans. His latest powered the Team AGNI machine to a historic TTXGP victory around the famous Isle of Man Mountain Course. Born in December 1955, Cedric Lynch developed a fascination with anything electrical or mechanical which turned into a life obsession.

Brazil is the third largest renewable energy generator
In addition to clean energy, Brazil stands out for its biofuel production. Influenced mainly by ethanol, Brazil is the second largest biofuel producer in the world.

Ethanol Biofuel

The largest national use of ethanol biofuel exists in Brazil (gasoline sold in Brazil contains at least 20% ethanol and hydrous ethanol is also used as fuel). In order for ethanol (ethyl alcohol) to be suitable for use as a replacement to petrol in its pure form, it must be distilled to at least 70-80% purity by volume before use.

Today almost 50% of Brazilian cars are able to use 100% ethanol biofuel, that includes ethanol only engines and flex fuel engines. Flex fuel engines are able to work with all ethanol, all gasoline or any mixture of both, giving the buyer a choice between price and performance.

MIT's Solar Electric Vehicle Team, the oldest such student team in the country, has just finished construction of its latest high-tech car and unveiled it to the public this Friday. "It drives beautifully," said George Hansel, a freshman physics major at the Massachusetts Institute of Technology and a member of the team. "It's fun to drive and quite a spectacle." With six square meters of monocrystalline silicon solar cells and improved electronic systems and design, the car can run all day on a sunny day at a steady cruising speed of 55 mph. The car will be competing in October in the World Solar Challenge race across Australia, and in preparation for that the team plans to drive the car across the United States over the summer. About a dozen team members are expected to go to Australia for the race, although only four will drive the solar car in the competition.
