NZ based man developing a modern pulse jet with some original ideas. Bruce is a competent engineer and has had substantial success in other areas of endeavour. A must see site for anyone with any sort of interest in pulse jets or amateur built aero engines of any sort. http://www.aardvark.co.nz/pjet/ IMHO his attention to personal safety appears inadequate for systems with this level of danger. An example engine has 100 pounds thrust in an easily man-portable unit that looks something like a fattish Bazooka. He has used it to power a Go-Kart. ___________ Site ref from David L -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
