Water-propelled jetpack hits the market for $99,500 (w/ video)

(PhysOrg.com) -- A water-propelled jetpack called Jetlev R200 is possibly the most fun-looking water activity yet. The Florida-based company Jetlev Technologies, Inc., working with German company MS Watersports GmbH, has recently started limited production in a phased roll-out program. At a cost of $99,500 per jetpack, the target market for the recreational device is holiday resorts.

The Jetlev is lighter (30 pounds [14 kg] when dry) and less bulky than other jetpack designs because its four-stroke, 250-hp engine and fuel are located on a small boat that is tethered to the jetpack by a 33-ft (10-m) hose. As the pilot steers the device, the boat follows along in the water. The boat delivers water to the jetpack through the hose, and thrust is generated by forcing the water downward through the nozzles located on each side of the jetpack.

Jetlev Technologies says that this design greatly improves the thrust-to-weight ratio compared to other jetpacks, allowing the Jetlev to propel a 150-lb (68-kg) pilot to speeds of up to 22 mph (35 km/h) at heights of up to 28 ft (8.5 m). The Jetlev can accommodate pilots who are 4.9-6.5 ft (1.5-2 m) tall and weigh 88-330 lb (40-150 kg). With a 26-gallon (100-liter) tank, the Jetlev can operate for about one hour at full throttle or up to three hours at cruising speeds.

The company also says that most people can learn how to fly the Jetlev after a few minutes of in-water instruction. Thrust is controlled through grip twist, while lifting the control arms up and down can move the pilot forward or backward by changing the angle of the nozzles. Differential nozzle angles allow the jetpack to be turned left and right. The Jetlev also has several safety features, including a 5-point quick-release harness, protective backrest, head support, and inherent flotation.

The ride is not uncomfortable, since the pilot’s weight is supported by the padded unicycle-style saddle and leg trapeze. Although pilots must be at least 18 years old, the company says that “if you are 82, healthy and in good physical condition, there is no reason why you could not fly.”

Designed for both fresh and salt water, the Jetlev’s exposed metal pieces are made of either stainless steel or hard coat anodized aluminum with Teflon coating to protect against corrosion and abrasion.

You, Too, Could Own a Working Jetpack for $90,000

From: http://www.gearlog.com/

Near the top of the list of "unfulfilled science fiction concepts," you'll find the jetpack, a staple of future transportation that somehow hasn't arrived yet. (Well, we did get the Segway.)

Nonetheless, Martin Aircraft Company wants to change that with the Martin Jetpack, a $90,000 carbon fiber model that can generate 600 pounds of thrust. Wired reports that the jetpack is self-righting; you can let go of the controls and just hover.

The Martin Jetpack runs on gasoline, and burns through its five-gallon tank in about half an hour. It's classified as an ultralight aircraft, so you don't need a pilot's license, although the company enforces its own training program.

Anyone who wants one faces a 12-month wait; to get on the list, you'll need to put 10 percent down ($9,000).

Strap-on mini helicopters the latest way to travel

By Tamara McLean

FORGET bungy jumping and black river rafting: New Zealand's tourists will soon be able to whiz around in a strap-on mini helicopter to get their thrills.

A Kiwi inventor will launch public flights in the latest jetpack flying technology early next year, with plans to expand to Australia soon after.

The Martin Jetpack – literally a personal strap-on aircraft – is a two-litre jet-powered engine designed to soar across the skies at 100km/h at heights of up to 50 metres.

Inventor Glenn Martin dreams of the day commuters will hop into the contraption to fly to work, missing rush hour traffic.

But for now, the first public flight program will be limited to low and slow flying in a controlled area while the Christchurch-based company road tests the safety and limits of the engine.

Set to thrill ... the Martin Jetpack is a personal strap-on flying engine.

"Just because we have to stay under 10 metres high and under 10km/h doesn't mean it won't be an incredibly exciting experience," Martin Aircraft Company chief executive Richard Lauder said.

"It will still be flying as it's never been done before, just in the confines of a rugby field-type space."

Exhibit A

The flights are expected to cost about the same as a bungy jump or a tandem skydive, and will require just a few minutes training before a person can strap in and take a solo flight.

"It makes sense to start this up at our Christchurch base but ultimately we want to take to Australia, the US and the rest of the globe too," Lauder said.

The public flights have been decades in the making for Martin who first developed the jetpack design in 1981. The invention didn't grab world headlines until a streamlined version was launched at the United States annual show in Oshkosh, Wisconsin a year ago.

Since then, orders have been rolling in for the first $US100,000 ($158,503) packs, with at least two wealthy Australian businessmen among those most keen to own one.

But Lauder says the company has had to halt personal orders until a big commercial operation like a military agency, border control or rescue organisation has trialled the packs.

"We had to rethink our plan to release it to make it very safe," he said.

"As much as we wanted to sell to very keen Australians, we need to see it used successfully by a corporation with strict protocols and structures in place before we just start giving them out for members of the public to fly around in."
