I saw this prototype and my first thought is it should be an outboard powerhead! OK maybe not, it's got a bit of power for that, but...

It's made by Angel Labs at http://www.angellabsllc.com/index.html

Some basic facts I would like to point out: The MYT engine weighs 150 pounds, measures 14 inches in diameter & 14 inches tall. It's internal geometry when operated for two revolutions will displace 848 cubic inches. In normally aspirated setup it makes 850 horsepower. Every two revolutions will generate 32 exhaust pulses, should really scream! The engine is air & oil cooled, with no water-cooling needed. It can be run in CCW or CW rotation with apparently no major changes made. If turbo-charged, this engine can make 3000 Horsepower

Unfortunately, the site doesn't seem to say anything about how many rpm's this engine is running. Just that future development will see unusually high numbers.

The tricky parts are only explained in the patent, which Angel Labs has made available: http://www.angellabsllc.com/docs/6739307.pdf - this file is 1.34 Megs

I know this might never happen, but lets contemplate installing one of these things into a boat.
