Their web site proclaims, “HyPoint, Inc. is developing the next generation hydrogen fuel cell system with zero CO2 emissions and game-changing energy performance for the air transportation and urban air mobility market.”  Pointing out a “fundamental barrier at a chemistry level” for lithium-ion batteries, the fuel cell maker launches some seemingly outrageous claims. HyPoint states, “Our patented technology increases operational time and utilization rate while decreasing TCO (total cost of operation) of any flying platform.”  They claim “5X operational time, 10X utilization rate, 20X faster charge,” and a TCO 90 percent of equivalent battery-powered systems. As we have reported here, demonstrated outputs for lithium-ion cells are around 350 Watt-hours per kilogram, and about 260 Whr/kg at the pack level.  HyPoint says it can already demonstrate a system-level …

Electric Beaver Flies in Vancouver, B. C.

Residents of Vancouver, B. C. were not awakened by the overhead passage of a DeHavilland Beaver Tuesday morning.  The electrically-powered floatplane lifted off at around 8:30 a. m. and zipped by quietly, its Magnix motor humming and only its four-bladed propeller disturbing the air.  The full-flight video below has the airplane “taxiing” for the first four minutes. Harbour Air took the daring step of publicly test flying an old but spiffily refurbished airplane with a new motor, the paint scheme revealing the location of all major electrical components.  Even more daring, Greg McDougall, founder and CEO of Harbour Air piloted the flight.  Talk about faith in your product. Engine/Motor Swap The Beaver’s original Pratt & Whitney R-985 engine produced 450 …
