Douglas (or Doug) Malewicki is an American aerospace engineer and inventor. Many of his inventions concern flying vehicles, but the range is quite diverse.〔(www.canosoarus.com — Douglas Malewicki's invention Web site )〕 He is also the concept creator and inventor of Skytran PRT (Personal Rapid Transit). 〔(Biography page at CarbonAngel. )〕 == Green vehicles == Douglas spent the past 25 years advancing the Skytran concept: ultra-light computer-controlled cars hanging below aluminum Maglev (magnetic levitation) tracks that could be supported above roads just by utility poles or the sides of buildings. Skytran basically combines maglev (which allows high speeds) and a hanging design (more stable; smaller tracks) with the 1960's idea of Personal Rapid Transit (PRT) -- cars individual commuters take directly to their destination (hence "Personal"), but computer-driven and available to others after they exit (hence "Transit"). Another key PRT idea Skytran follows is exiting the main track for boarding; so the cars behind don't need to wait as they do with mass transit vehicles. 〔(About Doug Malewicki and the Skytran concept ) at BigThink.com including a video interview with him〕 His ideas have inspired other variations on PRT, and speculation about the social effects of high-speed computer-controlled transport. 〔See (Malewicki's bio ) on the original Skytran website Skytran.net. 〕 〔(maglevprt.org ) contains speculation about social and economic effects of transporting people and goods much more freely.〕 Douglas developed the 157 and 156-miles-per-gallon "California Commuter" cars that hold the Guinness fuel economy records for street-legal vehicles driven at freeway speeds—an example of green vehicles.〔(The California Commuter ), canosoarus.com, accessed March 21, 2011.〕 He studied and developed various engineering solutions for Highly-aerodynamic Human-powered vehicles such as Recumbent bicycles.〔Gross, AC, Kyle CR, and Malewicki DJ.
