First Hybrid-Electric Plane Takes Flight Over Maui

Hybrid-Electric-Plane

The Honolulu Star-Advertiser – In a demonstration flight, the Electric EEL flew from Maui’s airport to Hana and back entirely on a single hybrid-electric charge. The company says the plane is like a Prius in the sky, and it’s the first of its kind. For the first time, a hybrid-electric plane has taken to the skies above Maui.

Ampaire Inc., a Los Angeles-based company focused on electric aviation, conducted its first, 20-minute demonstration flight in its Electric EEL—a hybrid-electric plane — from Maui’s Kahului Airport to Hana and back on Nov. 22 on a single charge.

Ampaire said it is the first to complete a demonstration flight of a hybrid-electric aircraft along an actual airline route. Ampaire is now flying the route regularly as part of a one-month demonstration program in partnership with Mokulele Airlines. Mokulele is one of 15 airlines around the world that signed a letter of interest with the company.

“We’re following the successful path of hybrid-electric automobiles in transforming ground transportation by taking that model to the sky, ” said Ampaire CEO Kevin Noertker in a news release. “By upgrading current aircraft with hybrid-electric propulsion we can enter the market quickly and take advantage of existing infrastructure for fixed-wing aviation.”

‘Air-Gen’ Device Generates Electric Power from Ambient Humidity (by Sci-News)

science-news

(Sci-News) A thin-film device made from nanometer-scale protein wires harvested from the microbe Geobacter sulfurreducens can generate continuous electric power in the ambient environment, according to a new study published in the journal Nature.

“We are literally making electricity out of thin air. The Air-gen generates clean energy 24/7,” said Dr. Jun Yao, an electrical engineer at the University of Massachusetts Amherst.

“It’s the most amazing and exciting application of protein nanowires yet,” added Professor Derek Lovley, a microbiologist at the University of Massachusetts Amherst.

The Air-gen device can generate power even in areas with extremely low humidity such as the Sahara Desert.

“It has significant advantages over other forms of renewable energy including solar and wind, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and it even works indoors,” Professor Lovley said.

The device requires only a thin film of protein nanowires less than 10 microns thick.

Indoor climate plays a key role in health protection, as pathogens remain in rooms for hours at typical air exchange rates in residential and office buildings. An increase in fresh air supply is recommended. To monitor and control the air quality, innovative CO2 sensors like the new XENSIV™ PAS CO  from Infineon provide precise, cost-effective, and space-saving solutions.EE Times
