Comments Off on The E-Fan X jet heralds an electric passenger plane revolution

The E-Fan X is a hybrid-electric jet plane that may herald a new era of electric power in transportation . Designed by a consortium that includes Airbus, Rolls-Royce and Siemens, the E-Fan X will offer partially electric powered flights that are cheaper, quieter, and more sustainable. “Aviation has been the last frontier in the electrification of transport, and slow to catch up,” said Rolls-Royce chief technology officer Paul Stein, according to the Guardian.  “This will be a new era of aviation.” This breakthrough in energy-transportation technology, which may encourage the growth of short-distance, small-to-medium passenger capacity aircraft, could change how airports are structured and incorporated into urban design . While the E-Fan X will be a major step forward for electric planes , it will fly on a hybrid engine because purely electric passenger flight is beyond current technological limits. “Aviation has always eluded electrification largely because of the size and weight of components involved,” said Stein, according to the Guardian . “But technology has moved on apace. Electrification is now poised to make a significant impact.” In light of these advances in the field, there is likely to be growth in three kinds of electric planes.

These would most likely be used to avoid urban congestion on the ground if one needs to cross a city . The second group includes regional jets, such as the E-Fan X. “Our target end game is a fixed wing, regional hybrid design,” said Stein. The third group includes long-distance commercial jets, which are much less developed under current technology. However, battery technology has made great leaps and bounds in recent years, so perhaps it may not be as faraway as we think. Via the Guardian Images via Airbus

New 1 km solar road opens in Jinan, China

Comments Off on New 1 km solar road opens in Jinan, China

China is getting in on the solar road -building action. A one-kilometer stretch of solar highway developed by Qilu Transportation Development Group just opened for testing near Jinan, the capital city of China’s Shandong Province. According to Quartz the expressway has three layers: the solar panels rest in the middle, with insulation below and transparent concrete on top. Solar panels sprawl across 5,875 square meters, or around 63,238 square feet, covering two lanes and one emergency lane in China’s new solar road now open for traffic. These panels can generate one million kilowatt-hours of clean power every year – that’s enough to meet the daily needs of roughly 800 households, according to Xinhua . Project designer Zhang Hongchao, in an interview with CCTV cited by Quartz, said the road can handle 10 times more pressure than normal asphalt roads. Related: France officially opens world’s first solar panel road Qilu Transportation Development Group chairman Xu Chunfu told Xinhua, “The project will save the space for building solar farms and shorten the transmission distance.” The electricity generated by the solar road could go towards powering street lights, a snow-melting system, surveillance cameras, signboards, and toll gate facilities, with excess energy sent to the state grid. The plan is for the clean power to one day also charge electric vehicles . Xu did not disclose the project’s cost to Xinhua, but did claim it was half of similar projects in other countries, saying, “With the development of solar power in China, the cost can be further reduced.” Zhang said the road cost about 3,000 yuan, or $458, per square meter, and as that is more than regular streets, it may take some time for the project to expand. The Qilu Transportation Development Group described the road as the “world’s first freeway photovoltaic pavement experiment section.” There are other solar roadways throughout the world – around a year ago France opened a one kilometer-long solar panel road in Tourouvre-au-Perche.
