Carmack's Throatless Rocket Engine

Baldrson writes "John Carmack is working a potentially disruptive technology: A throatless rocket engine. Its made from plain aluminum pipes with few machined fittings. Carmack says: "The great thing about these engines is that it only takes me two nights to machine the parts, so we can test two engines a week if necessary." It scales too: "If this line of tube engine development works out, we can make a 5,000 lbf engine with very little more effort than the test engine." This is what makes disruptive technology development work: Cheap, fast turnaround on on redesign producing technologies that scale. If this works, the NASCAR guys may really start entering space competitions like the X-Cup."

Yeah, I have no idea about NASCAR and just preying on stereotypes...so sue me.

You're saying that America has more roads than Europe? I very much doubt that, most of America is open wasteland.

Get a sense of humor, asshole.
