Miraculous aerocraft may fly 5 continuous years

Miraculous aerocraft may fly 5 continuous years

aerocraft_01

The aerocraft, with its 150-meter-long Z-type wing, can adjust its posture to absorb as much solar energy as possible. When flying in darkness, it will adjust the wing into a more aerodynamic position driving the plane with energy stored in the solar panels.

With the designed flight altitude of about 60,000 to 90,000 feet, the aerocraft can play a special role in military reconnaissance, communication and environmental monitoring while dealing with upper-atmosphere observation without pollution.

The unpiloted aerocarft was developed in the “vulture” plan by Aurora Flight Sciences, an American company. The plan was supported by BAE Systems, CS Draper Laboratory and the Sierra Nevada Corporation.

Currently, they have exhibited the first scale sized sample; and they would like to make a half sized sample before finishing the whole plane in 5 years.

Teenager invents solar panel that could be solution to developing world's energy needs..made from human hair

Teenager invents solar panel that could be solution to developing world's energy needs..made from human hair

A new type of solar panel using human hair could provide the world with cheap, green electricity, believes its teenage inventor.

Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world's energy needs.

The young inventor says hair is easy to use as a conductor in solar panels and could revolutionise renewable energy.

In a first step toward turning highways into energy-generating solar panels, the Sagle, Idaho-based startup Solar Roadways has recently received a $100,000 grant from the US Department of Transportation (DOT). The company will use the money to build a prototype of its Solar Road Panel, made from solar cells and glass, that is meant to replace petroleum-based asphalt on roads and in parking lots.

The 12- x 12-foot panels, which each cost $6,900, are designed to be embedded into roads. When shined upon, each panel generates an estimated 7.6 kilowatt hours of power each day. If this electricity could be pumped into the grid, the company predicts that a four-lane, one-mile stretch of road with panels could generate enough power for 500 homes. Although it would be expensive, covering the entire US interstate highway system with the panels could theoretically fulfill the country's total energy needs. The company estimates that this would take 5 billion panels, but could "produce three times more power than we've ever used as a nation - almost enough to power the entire world."

Algae-coated buildings touted as climate fix | Green Tech - CNET News

Engineers envision that long plastic tubes, called photobioreactors, be integrated into building designs or retrofitted onto existing skyscrapers.

Algae would grow from pumped-in carbon dioxide and sunlight and be harvested for use either as a liquid fuel to run in a combined heat-and-power unit or turned into biochar, or charcoal used as a soil conditioner that also sequesters carbon from the air.

‘Air shower’ set to cut water use by 30 per cent (Media Release)

‘Air shower’ set to cut water use by 30 per cent
As Australians become increasingly alert to the importance of using water wisely in the home, CSIRO researchers have found a way to use a third less water when you shower – by adding air.
9 November 2006

The scientists have developed a simple ‘air shower’ device which, when fitted into existing showerheads, fills the water droplets with a tiny bubble of air. The result is the shower feels just as wet and just as strong as before, but now uses much less water.

The researchers, from CSIRO Manufacturing Materials Technology in Melbourne, say the device increases the volume of the shower stream while reducing the amount of water used by about 30 per cent.

Given the average Australian household uses about 200,000 litres of water a year, and showers account for nearly a third of this, the ‘air shower’ could help the average household save about 15,000-20,000 litres a year. If you extend this across the population, that is an annual saving of more than 45,000 Olympic-sized swimming pools.

House Passes 'Cash for Clunkers' Bill




The House passed a plan to boost auto sales by providing vouchers of up to $4,500 for consumers who turn in their gas-guzzling cars and trucks for more fuel-efficient vehicles.

Under the House bill, car owners could get a voucher worth $3,500 if they traded in a vehicle getting 18 miles per gallon or less for one getting at least 22 miles per gallon. The value of the voucher would grow to $4,500 if the mileage of the new car is 10 mpg higher than the old vehicle. The miles per gallon figures are listed on the window sticker.

Owners of sport-utility vehicles, pickup trucks or minivans that get 18 mpg or less could receive a voucher for $3,500 if their new truck or SUV is at least 2 mpg higher than their old vehicle. The voucher would increase to $4,500 if the mileage of the new truck or SUV is at least 5 mpg higher than the older vehicle. Consumers could also receive vouchers for leased vehicles.
