As you might have guessed, a standard front engine avoids the afterburner setting cars on fire when the Frictionator hits the streets. [Frictionator via Jalopnik]

John Carnett modded brand new Polaris RZR 2-seater ATV with a grey market, 40-year-old turbine. The result is a 114db joystick-driven vehicle that spews out 1300°F exhaust to achieve around 60MPH. And it sounds glorious.

Our only regret is that Carnett was too sane to take his jet ATV over any sweet jumps. Give him time, though. A guy who builds stuff like this has to be slipping a bit. [PopSci]

Ever since we started putting high-powered engines into jets, there has been a long line of skilled but misguided lunatics eager to rip them out to use in their stupid and dangerous contraptions. Simply put, we are fascinated by speed—whether it is the latest military super aircraft or a flaming toilet blazing down the road at 70 mph. A jet engine attached to anything is sure-fire entertainment—as the following ten gadgets will demonstrate.

Jet-Powered Toilet: Powered by a Boeing Jet engine, this outhouse can reach speeds in excess of 70 mph—giving it the distinction of being the "fastest toilet in the world." The way I see it, that puts inventor Paul Stender on the same level as Chuck Yeager. [Link]

Jet-Powered Bicycle: Robert Maddox has a unique hobby—he builds and sells pulse jet engines. He is also a man that understands the value of a little viral marketing. That's why he decided to strap one of his kerosene-powered pulse jet engines onto an old-timey bicycle and ride it down uneven country roads at speeds up to 75mph. [Link]

Jet-Powered Kayak: A race between a jet-powered Kayak and a souped up off-road vehicle? Man, I love Top Gear. [Link]

Jet-Powered Grocery Cart: Using pulse jet engine instructions he found on the internet, a microlight instructor named Andy Tyler fashioned a grocery cart deathtrap that can reach speeds of around 50 mph. [The Sun]

Jet-Powered Wheelchair: A grocery cart that can hit 50 mph is impressive, but it doesn't compare to a wheelchair that can do 60. Next up—attaching a jet engine to a Rascal to help Grandma retain her independence. [Link]

Jet-Powered Rollerskates: An Aston Martin V8 Vantage vs a guy on rollerskates with a 300 horsepower jet engine strapped to his back? Yeah, Top Gear again.

Jet-Powered School Bus: Apparently, this heavily modified school bus is packing a 40-50's era Westinghouse J-34 Turbojet under that bright yellow exterior. These engines were capable of producing at least 3000 pounds of thrust—but since the bus never moves it's hard to tell how fast you could get to school riding in this thing.

Jet-Powered Scooter: I've been seeing a lot more scooters on the road in the States since gas prices became an issue—usually lumbering down the road in front of me when I'm trying to get somewhere in a hurry. That woudn't be a problem with this modified version however. The addition of two JFS 100 jet engines should get this little guy going over 40 mph no problem. [Ron Patrick Stuff]

Jet-Powered Road Luge: Using a small 90,000-rpm jet engine, luge rider Joel King was able to hit a world record top speed of 112 mph. [Link]

Jet-Powered Minivan: Traditionally, getting a minivan is a sign that your youth and freedom has given way to a fully suburbanized/domesticated lifestyle filled with PTA meetings, landscaping issues and grocery store coupons. At least one man, Chris Krug, decided to fight back by installing a Rolls-Royce Nimbus helicopter jet turbine engine with 1,000 shaft horsepower at 2,100 RPM into his Dodge Caravan. [Link]

Bonus: The previous ten gadgets dealt with jet engines being misused as a mode of transportation. Truth be told, it's probably not a good idea to use one to start a bonfire either. Although you can't argue with the results. [Link]

But have you ever heard one of those radio controlled jets whining away at full tilt? It's a shrill scream that stays with you for a while, making you feel like you just sat through a couple of Grand Funk Railroad concerts in a row (for all you youngsters, that group is called "the loudest rock and roll band in the world"). A server cooled with one of those pocket rockets will have to be buried deep underground. Better get some nice long cables. – Charlie White
