Here's what our readers and staff are buzzing about from around the world this week: | An Australian company’s alternative wind-turbine design has 30 blades instead of the traditional three – but, ironically, it’s much quieter than the typical noisy rotors. At least, that’s the claim made by Renewable Energy Solutions Australia, the manufacturer of the Eco Whisper turbine. The company said the turbine is “virtually silent,” thanks to its unique design, in which the 30 blades are angled outward from the hub, and surrounded at their ends by a ring. This ring, the company says, “prevents air ‘spilling’ off the tip of the blades,” the source of much of the noise that traditional turbines produce. The company also lists greater efficiency and lower start-up speeds as advantages compared to competitors.
| The MPG Marathon is the UK’s best known and longest running economy driving event. Now in its eleventh year, the MPG Marathon is where drivers team with automakers to squeeze every drop of fuel economy out of their cars, and is also seen as a proving ground where automaker’s mileage claims are either bolstered or seriously questioned. Organized by Fleet World magazine, the Marathon also recognizes those drivers and their cars which record the greatest percentage improvement over the manufacturers’ published fuel consumption ratings. The event took place earlier this month, with participants putting their economy driving skills to the test around a 370-mile route that included steep hills, twisting country lanes and inclement weather in southern England.
| Jay Godsall, founder and chief executive of Toronto-based Solar Ship had what he, and just about everyone agreed, was a crazy idea. A hybrid airship with helium filled wings and topped with solar cells that power its battery-assisted motors. The ship combines the static lift of a blimp and the aerodynamic lift of a conventional plane. Crazy alright. So crazy that it makes perfect sense.
The Solar Ships require only short take off and landing strips and therefore can go where other aircraft can’t. Combined with the ability to carry heavy payloads over extremely long distances mean that the Solar Ship h as a number of new applications including disaster relief, exploration and field research, remote cargo delivery, linking remote communities, and military applications.
| With a annual utility bill of more than $15 million, it’s no wonder Edwards Air Force Base is looking to solar energy as a way to save money. (It also doesn’t hurt that Edwards is in California’s Antelope Valley, a hot-spot for solar development.) The base has begun work on the installation of three 1-megawatt (MW) solar farms at its flight test center. The move comes after nearly three years of planning and coordination with Southern California Edison ( SCE), the California Public Utilities Commission ( CPUC) and environmental agencies.
The systems will be owned and maintained by Borrego Solar, a commercial solar developer based in El Cajon, Calif. The base will buy the power produced at the facility under a power purchase agreement. The flight test center will also purchase power from SCE under its net metering program, which allows it to seamlessly switch from solar power to grid power when the sun goes down. The project is expected to be completed around the end of the year. | | | | | | | | |  | |
