Second: The Fuel. Especially military flight fuel is bloody near kerosene.

Third: There are so many. It may be a myth but after 911 when so many planes were grounded the tempeture dropped a degree.

So this is kinda cool. Maybe we should call them personal air taxi’s or something. Yes they will be expensive. So what.

Harbour Air wants to become the world’s first all-electric airline and start flying passengers by 2022.

It’s becoming increasingly difficult to ignore the fact that air travel is a massive and growing problem for the global climate.

In the US, transportation is now the largest source of greenhouse gas emissions, and aircraft account for 12 percent of transportation emissions. US air travel reached a record high last year, pushing up overall emissions even while the power sector saw a decline.

To make matters worse, demand for flights is growing. Emissions from air travel are poised to spike up to sevenfold globally by 2050 if nothing else changes.

That’s why it’s so urgent to decarbonize air travel. Yet the technical challenges are immense. Alternatives like carbon-neutral biofuels remain far too costly. And the stodgy rules in the heavily regulated, risk-averse aviation sector lag far behind advances in electric drivetrains.

Lighter-than-air craft rise again

f you like the idea of cruising on a ship in laid-back luxury, but prefer the speed and convenience of air travel, there may soon be a solution. Drawing their inspiration from the airships of yesteryear, a new generation of airship-like vehicles could soon be making their way across our skies.

In a hangar outside Tustin in California, engineers are preparing one of the most radical designs for testing.  The Aeroscraft, as it is known, is the brainchild of Igor Pasternak and has been made possible by advances in materials and computer control systems.

“We are resurrecting [the airship] with new composite fabric structures, that are stronger, lighter, more versatile” says Fred Edworthy, of Aeros, the company building the lighter-than-air vehicle.

The airship in the hangar is being built to test various key components of a design that could one day contain a hotel, casino or spa. However, the company believes one of its biggest markets could be transporting freight from hard-to-reach locations or, for example, carrying wind turbine blades. Currently blades are as large as they can be to be transported on a truck.

It’s an Airplane, It’s a Jet Ski, It’s the Electric FlyNano

The newest electric airplane to make its first flight is squarely aimed at recreational fliers, even those without a pilot’s license. The FlyNano turned some heads at last year’s Aero Friedrichshafen aviation trade show in Germany thanks to its interesting design. The FlyNano is a miniature electric flying boat, making it essentially an airborne jet ski.

The original airplane was going to have a gas engine powerplant, but the Finnish company says the ever-improving electric motors and batteries means FlyNano will be an all-electric airplane moving forward.

The first flight was a very short one, just a handful of seconds. And the airplane didn’t really get out of ground effect. The wing area looks rather small for an electric airplane compared to other models we’ve seen, which tend to have the efficient, higher-aspect-ratio wings typical of sailplanes.

The designer claims a 10,000-foot ceiling for the airplane, but that might be a bit optimistic with the current setup. FlyNano says it will continue flight testing throughout the summer. We’re looking forward to seeing longer and higher flights, though the FlyNano could be fun as an aircraft designed to fly in ground effect.

The Real Reason the Military is Going Green

Retired Brig. Gen. Steven Anderson calls himself  “an accidental environmentalist.”

His epiphany about climate change started with a tactical problem. In 2006 and 2007, when he served as the military’s chief logistician in Iraq, he coordinated the transport of millions of gallons of fuel across the country to power everything from vehicles to the large compressors used to cool individual tents—or, as Anderson puts it, for “air conditioning the desert.” He was taking one casualty for every 24 fuel convoys, and he was doing 18 convoys a day. That’s one casualty every other day. He needed to get the trucks off the road. He needed to find a way to reduce the military’s fuel use.

“There’s a direct relationship between energy and the military. The more energy consumed, the less effective you are militarily because you’re more vulnerable,” said Anderson, who reported to General David Petraeus. “They love to take out our field trucks. They make a big boom when they do.”

Since then, Anderson, like many military leaders, has realized that guzzling oil makes the United States vulnerable in other ways. “I’m a soldier,” Anderson said. “Why should I be concerned about climate change? Climate change brings about global instability. That makes the world more vulnerable and it’s more likely that soldiers like myself will have to fight and die somewhere.”

Never mind D.C. conservatives who claim to be tough on defense and suspicious of climate science: The Department of Defense isn’t denying that climate change is a major national security threat. “The change is happening. It’s just a reality,” said retired Marine Col. Mark Mykleby, a former strategy assistant to the Joint Chiefs of Staff. “Science tells us it’s coming our way.”

Energy, politics, and more

U.S. military kicks more ass by using less fossil-fuel energy

By David Roberts

This is my contribution to a dialogue on the military and clean energy being hosted by National Journal.

To understand the promise of renewable energy for the U.S. military, it helps to start as far from Washington, D.C., as possible. (This is true for most forms of understanding.) Start far from the politicians, even from the military brass, far from the rooms where big-money decisions are made, far out on the leading edge of the conflict, with a small company of Marines in Afghanistan’s Sangin River Valley

Not long ago, for a three-day mission out of a forward operating base in Afghanistan, each Marine would have humped between 20 and 35 pounds of batteries. One of the reasons Marines are so lethal in such small numbers today is that they are constantly connected by radios and computers. But radios and computers require a constant supply of batteries, brought by convoy over some of the deadliest roads on earth and then piled on the backs of Marines in highly kinetic environments.

In late 2010, India Company, from the 3rd Battalion, 5th Marine Regiment, tried something new. They packed Solar Portable Alternative Communications Energy Systems, or SPACES — flexible solar panels, 64 square inches, that weigh about 2.5 pounds each. One 1st Lieutenant from India 3/5 later boasted that his patrol shed 700 pounds.

U.S. Army Launches Plan to Make All Military Bases Net Zero

Posted by Ggw Admin on Apr 19, 2011 in Blog | 0 comments

Over the past couple of years, the U.S. Army has announced several initiatives ranging from solar-powered tents for troops to hydrogen-powered tanks, however this is their most ambitious program yet. With the help of the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), the U.S. Army is aiming to have all Army installations across the country be net zero.

With funds from the DOE’s Federal Energy Management Program (FEMP), the “Army Vision for Net Zero” program will aim to meet mandates to reduce energy as a result of Executive Order 13514. The order calls for all new buildings to be net zero energy by 2030, and it dictates a 30 percent reduction in water use and a 50 percent reduction in waste that goes to landfills. On top of that, the National Defense Authorization Act also mandates that the Army produce or acquire 25 percent of its energy from renewables by 2025.

“The first priority is less,” Assistant Secretary of the Army for Installations, Energy Environment Katherine Hammack said. “If you use less energy, you don’t have to buy as much – or you don’t have to make as much from alternative energy sources or renewable energy sources. So if you look at energy, that is a focus on energy efficiency. If you’re talking about water, then that’s water conservation. Or even if you’re talking about waste, that’s reducing the amount of waste we have in the steam.”

The program already has a poster child in the form of Fort Bliss. The military base boasts solar daylighting in the dining facility, warehouse and gym, energy-efficient windows, utility monitoring and control for heating and air-conditioning systems in approximately 70 buildings, and plans to increase the on-site hybrid waste-to-energy/concentrating solar power plant from 90 to 140 megawatts. The City of El Paso has committed to provide 1 million tons per year of municipal solid waste, which will be transformed into energy by the base.

“The Army’s net zero vision is a holistic approach to addressing energy, water, and waste at Army installations,” Kingery said. “We look at net zero as a force multiplier for the Army that will help us steward our resources and manage our costs.”

Considering that defense is a massive cause of national debt, the plan serves two purposes – reduced spending and “greening” national security. If the military can get on board with renewable energy, it makes you wonder why other areas of government are having such trouble.
