Human Powered Airship

- Adam Clare

Airships are really neat, and so is going places under human energy (like bikes!). Combining two neat things can equal something awesome – a human powered airship!

airship or airHIP

Setting the bar pretty high for airship design is this one from Christopher Ottersbach: Called the Aeolus Airship (named after Aeolus, the Greek wind god) it is designed to be aerodynamic than conventional airship designs, and stay aloft for up to two weeks on a supply of helium and, furthermore, is pedal-powered by the crew of 2-4 people. That’s about all the tech detail I’ve come across; it’s certainly made the rounds in the past couple of days but no specific website or contact info seems forthcoming. Christopher, I’d love to talk to you if you come across this.

Algae Airplane Fuel Packs Power

- Adam Clare 1 Comment

A recent test flight of a unmodified airliner that used an algae-based biofuel was a great success! This is good news for air travelers as it will mean that their carbon footprint will be greatly reduced when airliners switch to the more efficient biofuel.

The test by Houston-based Continental, the fourth-largest U.S. airline, is a step toward the International Air Transport Association’s goal of having member carriers use 10 percent alternative fuels by 2017 to reduce global warming. The European Union will cap airline carbon-dioxide emissions beginning in 2012.

“We’re watching as different countries set carbon-reduction targets,” Leah Raney, Continental’s managing director of global environmental affairs, said in an interview. “We have been working very diligently to reduce our carbon footprint over the last 10 years.”

Aviation accounts for about 2 percent of global CO2 emissions, IATA estimates. More-fuel-efficient planes have helped Continental trim its output of heat-trapping gases 35 percent, Raney said.

Fuel of Future

U.S. carriers are testing alternative fuels after prices for traditional jet kerosene, which is derived from crude oil, surged to a record $4.36 a gallon in July. Jet-fuel prices have since collapsed about 60 percent amid a deepening recession.

“This demonstration flight represents another step in Continental’s ongoing commitment to fuel efficiency and environmental responsibility,” Chief Executive Officer Larry Kellner said in a statement. “The technical knowledge we gain today will contribute to a wider understanding of the future for transportation fuels.”

Coconut Husks as Car Parts

- Adam Clare 2 Comments

Coconuts have a very hard shell that can be used in many different ways, a new suggestion by a team of researchers says that the really good part of the shell is the coconut’s husk which can be turned into car parts.

The approach has potential because coconuts are an abundant, renewable resource in all countries near the equator, including the Philippines, Indonesia and India. The husks are burned or thrown away, generating garbage. This is the first time that coconut fibers have been used to make these automotive products, said Walter Bradley, an engineering professor who is leading the project.

In Ghana, as one of Bradley’s students told him, the discarded husks pile up in mounds, creating a health hazard because they collect water where malaria-causing mosquitoes can breed.

“We are trying to turn trash into cash to help poor coconut farmers,” Bradley said, adding that the long-term goal is to increase demand for coconuts to millions of pounds, and thereby raise their market price.

Currently, there are about 11 million coconut farmers in the world making an average annual income of $500, he said.

San Francisco Airport to Sell Carbon Offsets

- Adam Clare 1 Comment

San Francisco airport is trying out a neat idea- selling carbon offsets in the airport. It’s one way that you can make flying a little greener.

“We’d like people to stop and consider the impacts of flying,” said Steve McDougal, executive vice president for 3Degrees, a San Francisco firm that sells renewable-energy and carbon-reduction investments and is teaming up with the airport and the city on the project. “Obviously, people need to fly sometimes. No one expects them to stop, but they should consider taking steps to reduce their impacts.”

San Francisco’s Airport Commission has authorized the program, which will involve a $163,000 investment from SFO, but is still working out the details with 3Degrees. Because of that, McDougal said, he can’t yet discuss specifics, such as the cost to purchase carbon offsets and what programs would benefit from travelers’ purchases.

Top Ten Green Transportation Trends for 08

Inhabitat has a breakdown of what they see being the most significant trends in transportation in 2008.

3) IT’S NOT JUST ABOUT FUEL EFFICIENCY
Everyone is looking at emissions as the greatest contributor to global warming, but there is so much more that we can do to improve our methods of transportation. This past year Mazda showcased the Kiyora, a car that cleans water, while BMW showed a car that not only ran on hydrogen but also cleaned the air as it moved through the city. But none was as exciting to us as the super-environmentally friendly Eco-Elise, which was revealed by Lotus in July of this year. The vehicle was not just an energy-efficient vehicle, but was created with the greenest materials that the company could find. It’s like they read our minds!
