Seth Kettleman's custom-built jet-powered go-kart

Seth Kettleman is no stranger to high-powered vehicles. The surplus aircraft parts dealer provided the Boeing engine and technical support for the building of a jet-powered Batmobile replica, and more recently attempted to sell his own similarly-outfitted Datsun 280ZX on eBay. Now, you have the chance to buy another one of his monstrosities – a custom-built jet-powered go-kart.  Read More

Auto restorer and designer Casey Putsch has built a replica Batmobile, that is powered by ...

Last October, we told you about the full-scale working Batmobile replica built by movie prop-maker Bob Dullam. The version of the iconic superhero vehicle that Dullam chose to recreate was the rugged, Hummer-esque beauty from Batman Begins and The Dark Knight, known as the Tumbler. Well, that car now has some company on the road, in the form of a street-legal copy of the smoother, slinkier Batmobile that first appeared in 1989’s Batman. Built by Ohio auto restorer and designer Casey Putsch in just five months out of race car and military surplus parts, the vehicle is incredibly faithful to the original ... to the point that it’s powered by an actual jet engine.  Read More

The H2O Power radio generates its own operating power via the force of the running water f...

For all the people out there who like listening to the radio while they’re in the shower, various companies offer waterproof battery-operated “shower radios.” There’s nothing particularly wrong with these radios, but ... why change or recharge the batteries if you don’t have to? No, we’re not suggesting running a power cord into the shower. Instead, you might be interested in getting an H2O Power water-powered radio.  Read More

The Strait Power turbine inspired by the basking shark

Studying the bumpy protrusions on the fins of humpback whales has already led to more efficient wind and tidal power turbines and now nature is once again the source of inspiration for a new and more efficient hydroelectric turbine. The latest source of biomimicry is the basking shark, which industrial design student Anthony Reale has borrowed from to create "strait power," a water-powered turbine generator that tests have shown is 40 percent more efficient than current designs.  Read More

Atlantis Resources Corporation's tidal power turbine before installation on the sea floor

Even with its potential for providing predictable and sustainable electricity generation with no visual impact, tidal power still accounts for only a fraction of a percent of the world’s total electricity generation. That is slowly changing though, with numerous tidal power plants being constructed or planned for coastlines around the world. India is the latest country to wade into the tidal power waters with the announcement of its first commercial scale tidal current power plant to be constructed in the Indian State of Gujarat.  Read More

The modified blades

The bumpy protrusions, known as tubercles, on the leading edge of humpback whale flippers have already inspired more efficient wind turbine blades that are able to produce more power at lower speeds. Now, in a seemingly obvious move, researchers have found that that same principle can be applied to underwater turbine blades to more efficiently convert low velocity ocean tidal flow energy into electricity.  Read More

Gas turbine model train looks (and sounds) incredible

Developed by Hidepon Works, this train is about as bad-ass as model trains can possibly get. It's powered by a gas turbine engine, thus giving it a very noisy and very sexy jet-like sound as it prepares to "take off" on its run. We took a closer look at Make Fair in Tokyo.  Read More

Atlantis Resources Corporation has just unveiled its recently completed AK1000 tidal turbi...

The oil and gas fields of the North Sea have been meeting the power needs of the UK population for a number of years but such things have a finite lifespan and there are different ways to get power from the sea. The world's largest and most powerful tidal power turbine has just been unveiled by Atlantis Resources Corporation ahead of installation at a special berth at the European Marine Energy Center (EMEC) in Orkney, Scotland. The AK1000 will shortly be secured to the seabed off the choppy waters of Orkney and connected to the grid at EMEC. The company claims that the turbine is capable of generating enough electricity for 1,000 homes and is the first of a series of turbines to be deployed.  Read More

A low pass of the BonusJet (Image: Bill Pearson)

Gliders that have engines which can be used for take-off to remove the need for catching a tow to altitude by an airplane or a winch are quite common now. Such engines are usually of the electric or small-piston motor variety, but New Mexico-based company, Desert Aerospace, has gone a step further by fitting a glider with a retractable jet engine.  Read More

Risoe DTU's wind turbine blade section being tested in a wind tunnel

If you’ve ever seen a commercial-scale wind turbine in real life, then you’ll know that they’re huge – a single blade can be as long as 60 meters (197 feet). Researchers from Denmark’s Risoe DTU National Laboratory for Sustainable Energy tell us that such blades can flex by up to six meters (20 feet) when subjected to strong wind gusts. Worse yet, the gust load is often not evenly distributed along the length of the blade, so it doesn’t flex evenly. Fortunately, the researchers are working on addressing this problem, by attaching flexible flaps to the trailing edges of the blades. These flaps come in the form of silicone rubber strips, which run the length of the blade. The result, we’re told, will be quieter, higher-output turbines.  Read More
