Catastrophic Inequality in a Climate-changed Future

Turning Commercial Jets into Hybrids


A company called WheelTug has devised a way for commercial airplanes to run on electricity at slow speeds, much like a hybrid vehicle does.

The WheelTug system includes a pair of electric motors embedded in an airplane's nose wheel which provide power for backing the plane away from the gate and for taxiing up to 28 mph. The electricity for the motors is provided by the auxiliary power unit of the plane, a small engine located at the back of the aircraft used for running lights and the ventilation system when the main engines are off.

The auxiliary power unit uses only about half a gallon of fuel per minute compared to two gallons per minute for each of the main engines. The WheelTug allows a plane to taxi without use of the main engines and to back from the gate without the help of a diesel-fueled tug, cutting down significantly on fuel use while a plane is on the ground.

Another advantage to creating hybrid jets is that planes will spend less time on the ground since they won't have to wait for a tug. Also, by running the main engines less, engines will sustain less damage.

The company has just signed a deal to outfit 20 El Al jets with the system and hopes to get certification from European and American aviation regulators by early 2013.

California Hits 1 Gigawatt of Rooftop Solar


According to a new report by Environment California, a major solar power milestone has been reached in the state: it is now home to 1 gigawatt's-worth of rooftop solar power. To put that into perspective, only five countries have hit the 1 GW mark in solar power so far: Germany, Spain, Japan, Italy and the Czech Republic.

The electricity produced by rooftop solar power installations in California now equals two coal-fired power plants and could power 750,000 homes.

The solar installations include new and existing homes and commercial buildings, and panels connected to the grid by both large utilities and smaller municipal utilities.

The report gives most of the credit to a statewide rooftop solar incentive program called the California Solar Initiative. The initiative is responsible for 600 MW of installed solar power in the state.

Facebook Adding Solar Power to New Headquarters


Facebook, a company that so far hasn't done much in the "green" arena, is incorporating a nice-sized solar power system into their new headquarters.

The cogeneration system, which is being built by Cogenra Solar, will include both solar PV and solar hot water heating and have far greater efficiency than just a solar PV system alone. The 24-module system will reside on the roof of a 10,000 square foot fitness center, providing electricity for the fitness machines and hot water for the showers. The system will have a capacity of 10 kW of electricity and about 50 kW of thermal energy.

Facebook sees this as their initial investment in solar power and hopes to expand the system later on to include powering and heating other parts of the campus, like the cafes.
