Wave disk engine…
Michigan State University associate professor of mechanical engineering Norbert Mueller describes his Wave Disk Generator, for which he has received a $2.5 million grant from the U.S. Department of Energy to build a prototype new engine and generator technology that can dramatically improve efficiencies and reduce costs of electric hybrid vehicles.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Sorry, the comment form is closed at this time.
I read a little more into this and it essentially looks to me like a clever turbine engine design. I noticed he mentioned a relatively low output power of 25KW, which I assume helps explain the high gas mileage. I’d be interested to know more about the design details when it comes out
Here’s a link to a detailed technical paper describing the wave disk engine concept in detail for those interested:

Umm… I can make one of those on the CNC mill in my garage… perhaps one of these days I’ll give it a shot, see what happens…
