Comments Off on Electric airplane prototype breaks world speed records in test flight

An electric airplane build by Siemens recently set two new world records for battery-powered aircraft by reaching a top speed of about 210 miles per hour. It also became the first electric plane to tow a glider into the sky. The Siemens Extra 330LE prototype plane overcomes one of the key barriers to electricity-powered flight, the weight of the batteries and associated energy density. According to Electrek , Siemens has put a lot of work into the energy density of electric motors, and as a result the 330LE delivers a power output of 260 kilowatts with a weight of just 110 pounds. The end goal of Siemens’ work on this prototype is to produce airlines for regional travel that are powered by a hybrid-electric propulsion system—a project it’s working on in concert with Airbus, which is working on its own E-Fan electric plane concept. Check out the cool video below. As Clean Technica notes, the two records the plane set on March 23, 2017 at Germany’s Dinslaken Schwarze Heide Airfield include a top speed record of 337.50 kilometers per hour (over a distance of 3 kilometers, for an electric aircraft with a takeoff weight of less than 1,000 kilograms); and a top speed record of 342.86 kilometers per hour for an electric aircraft with a takeoff weight of over 1,000 kilograms. The latter record was achieved by tweaking the craft so it was a bit heavier. Pilot, Walter Extra broke the previous record – set by the American pilot William M. Yates in 2013 – by one minute and 10 seconds.

17 states challenge Trump’s climate policy in court

Comments Off on 17 states challenge Trump’s climate policy in court

17 American states are pushing back after President Donald Trump ‘s executive order targeting the environment last week. The New York -led coalition is legally challenging the Trump administration after the president’s attempts to undo Barack Obama’s Clean Power Plan . They say it’s the administration’s legal duty to regulate climate change -causing emissions . Trump’s executive order called on the Environmental Protection Agency (EPA) to suspend, rescind, or revise the Clean Power Plan, a law that would have required states to cut carbon dioxide emissions at power plants but which was challenged by 26 states led by Republicans. After the recent executive order, the EPA asked the United States court of appeals for the District of Columbia to delay proceedings over the law to give them time to review it. The 17 states say this move could delay litigation for years – time we need to spend acting on climate change. They asked the court to toss out the EPA’s request. Related: 75 American mayors affirm climate goals even after Trump executive order New York Attorney General Eric Schneiderman said in a statement: “The law is clear: the EPA must limit carbon pollution from power plants. In order to repeal Obama-era protections, the Trump administration must replace those protections, as well – and we know how well repeal-and-replace went the first time around. My office will continue to defend the Clean Power Plan and aggressively oppose any effort to stand down from our shared responsibility to protect our environment and our climate.” The 17 states – New York, California, Connecticut, Virginia, Delaware, Vermont, Hawaii, Rhode Island, Illinois, Oregon, Iowa, New Mexico, Maine, Minnesota, Maryland, Massachusetts, and Washington – were also joined by seven localities: the District of Columbia; New York City; Boulder, Colorado; Chicago, Illinois; South Miami, Florida; Broward County, Florida; and Philadelphia, Pennsylvania. According to New York’s press release, the Clean Power Plan could eliminate as much pollution as more than 160 million cars – 70 percent of America’s passenger cars – yearly could emit.

Comments Off on All-Electric SportStar EPOS Plane Takes First Flight

As electric vehicles claim an increasing share of the road, their counterparts in the air are just starting to take off. On March 28, the SportStar EPOS two-seater electric plane made its first 30-minute flight. Czech company Evektor-Aerotechnik designed the aircraft with a single 50-kW Rotex electric motor and a trapezoidal wing span of 10.46 meters. Powered by a 40-Ah battery from Kokam, the SportsStar EPOS can reach up to 260km/h with a cruising speed of 150km/hr.

Comments Off on Edison2?s New Very Light Car 4.0 Weighs Less than 1,100 Pounds

Edison2 just unveiled the latest version of its Very Light Car (VLC) at The Henry Ford Museum in Dearborn, Michigan. An earlier version of the vehicle won the $5 million Automotive X Prize back in 2010, and the new Very Light Car 4.0 incorporates safety innovations developed for long-distance racing cars and uses batteries and motors similar to those in standard EV’s. The new vehicle weighs less than 1,100 pounds, and the makers expect that their final production version will weigh under 1,400 pounds while still meeting federal safety requirements.
