Towerman April 20, 2015 06:37 AM The revolution has begun :D Mzungu_Mkubwa April 20, 2015 09:16 AM Surely this tech would allow the scaling of R/C multicopter drone designs to be able to carry people? Next they need to apply the same weight savings innovations to a generator (should be a short leap, right?) so that there can be a single central power unit (micro turbine?) for multiple remote engines. Preferably in a configuration similar to this: www.youtube.com/watch?v=fOJ8TWYUedA Larry English April 20, 2015 12:56 PM for once - this thing looks pretty good unlike bikes that hang you from a hammock, or doohickeys that re-invent old problems wle Jay Finke April 20, 2015 01:34 PM looks like it's water cooled, so much for the 150lbs ? email@example.com April 20, 2015 01:36 PM This has great potential if the load carrying can be scaled up and the electric power boosted with wing mounted solar panels to achieve higher speeds above the clouds. the.other.will April 20, 2015 02:19 PM At 260 kw, there's no need to talk about scaling up multi-rotor drones, there's enough to power existing small helicopters like the MD 500. Although the motor only weighs 50 kg, the aircraft will also need a fuel-burning powerplant of some sort. The Bishop of D April 20, 2015 03:00 PM Siemens may be killing two birds with one stone. A light yet powerful electric motor is far more important to the hybrid/electric car industry than to the aircraft industry, grtbluyonder April 20, 2015 06:01 PM What about the batteries, their energy capacity and their weight. How do these compare to avgas or diesel engines. So far batteries are a poor excuse for the energy density needs of transportation in cold climates. Andrej Radoš April 20, 2015 06:15 PM At Hobby-King: Turnigy RotoMax 150cc equivalent, at 2,5 kg, and 450$ almost 4kW per kilo. So do you get one of these Siemens for less than 12000$. .? Batteries and/or solar-cells weigh much more than the motor. cucotx April 20, 2015 07:55 PM I want this for use in Powered Parachuting. No more noisy gas engines. And how about this technology incorporated into a hybrid Jeep Wrangler. Electric motors providing the Jeep with maximum torque at 0 rpm. Sign me up.
