Submission + - New Internal Combusion Engine to use Shockwaves (

lorenlal writes: It appears that the Mechanical Engineering department at Michigan State University has come up with a design for a new type of hybrid engine. FTA:

The engine has a rotor that's equipped with wave-like channels that trap and mix oxygen and fuel as the rotor spins. These central inlets are blocked off, building pressure within the chamber, causing a shock wave that ignites the compressed air and fuel to transmit energy.

I just upgraded an app we've been developing in 3.0.0.rc2 and it went smoothly. Looking forward to actually having the docs in place.

We are truly stupid if we turn backwards right when we figure out how to do high efficiency fusion, store energy as extra mass, and other off the wall things we've cooked up in sci-fi but haven't gotten around to figuring out in the basic physics departments.
That quote is simply stunning. Clearly, us as a people and civilization is retarded if we are so dumb as to let "science" be the limiting step in progress and not just the imaginations of our sci-fi writers.

Not that much of the rest of the post isn't worth considering, but that statement surely needed comment. Clearly we're not even CLOSE to figuring out how to do all those things.
