Electric

Rechargeable lithium-ion batteries are the preferred power storage technology for the vast majority of portable devices, such as cell phones, laptop computers and MP3 players. They have also made their way into electric cars, but even with recent developments making them more effective, storage capacity continues to remain a problem. Now researchers at the University of St Andrews, with associates at Strathclyde and Newcastle, have developed a new type of air-fueled battery that could provide up to 10 times the energy storage of existing designs, paving the way for a new generation of electric cars and portable devices.

Nobody likes staring at a screen while they wait for their computer to boot up. Sure, you can spend those few minutes making a cup of coffee or ferreting the dirt out from under your fingernails, but if you’re raring to go those few minutes can be a frustrating waste of time. This could soon be a thing of the past however, thanks to a clever materials science technique that may allow a new class of electronic devices that remember their last state, even after power is turned off.

As you read this, 66-year-old Briton Eddie Sedgemore is powering his way all over the UK mainland, a 1,655-mile journey on a Powabyke X-byke electric bicycle to raise money for the British Heart Foundation. The Powabyke is a regular looking bike that has a 250 watt motor which slots into the water bottle holder and weighs only 2.5kg, allowing riders to coast along at a steady 15mph (add another 10mph in pedal assist mode).

Airports are windy places and it seems logical to harness this power to reduce operating costs and boost green credentials. In line with this, the environmentally minded Metropolitan Airports Commission (MAC) at Minneapolis-St. Paul International Airport (MSP) has recently installed 10 wind-powered electricity generators and purchased an electric-powered utility vehicle for use at the airport.

Military-funded projects often pave the way for a much better consumer product, and although the original DARPA funding of the development of the Tactical Electric No Signature (TENS) Mountain bike for Marines and paratroopers is now over a decade old, hold onto your hats folks, because the design has been upgraded and will be sold in limited quantities with a 1000 watt propulsion system. The TidalForce M-750 x2.0 is based around the commercially available (and ingenious) Montague Paratrooper folding bike but has a top speed of over 30 mph and range on a single charge is 25 - 28 miles, using the electric power only. The E+ advanced propulsion system features nine forward power modes, nine resistance (exercise) modes, cruise control and anti-theft. It folds to 3 x 3 ft, so it fits in the boot, and the componentry is first class with RockShox Tora 302 Forks, Shimano XTR brakes, FSA Gossamer 30/38/52 tooth crank set, Crane Creek Thudbuster ST seat suspension and a WTB Speed-V Seat. Like we said - highly-desirable. Read More

The Electric Vehicle Symposium (EVS) opens in Norway today and will see the official unveiling of a novel multi-speed electric vehicle gearbox by transmission specialist Vocis. Simulations show that a two-speed configuration could reduce the battery energy consumed by 5-10 percent over the industry-standard New European Drive Cycle, without any significant increase in overall cost or packaging volume, as well as extending battery life and providing the potential to substantially downsize the powertrain and battery pack.

There’s a few reasons why cycling has remained a popular form of transport for over a century. It’s cheap, keeps you fit, is environmentally friendly and it’s fun - usually. Unfortunately it can get a little less fun when you hit a steep hill or have neglected your fitness for a while. This is where electric assist devices such as the Gruber Assist can come in handy. It still lets you do most of the work, but helps to make the job that little bit easier. Whereas electric bikes such as the E+, the eneloop and the Gocycle require the purchase of a complete bike to get some electric assistance, the Gruber Assist can be retrofitted to practically any bicycle provided it has a seat tube with an inner diameter of 31.6mm.

Made up of more than 1200 mirrored heliostats surrounding a huge 54 story high tower, the world's largest solar power tower plant is now on-line near Seville in Spain. Developed by Spanish engineering company Abengoa, the PS20 plant generates 20 megawatts of electricity, enough to supply 10,000 homes. Concentrating solar thermal technology has been used in desert areas in Spain and the southwest U.S. for decades and is seeing a resurgence as utilities seek to reduce reliance on fossil fuels.

It's rare that you see a whole new segment open up in personal mobility - and this one looks like an absolute cracker. The Scarpar Powerboard is an off-road powered skateboard capable of taking on pretty much any terrain other than water. An electric or 4-stroke petrol engine powers two articulated tank-style tracks up to a terrifying 60kmh, using a hand control for acceleration and braking. Mud, grass, sand, snow - the Scarpar is capable of driving over just about anything, including rock piles and even fallen logs. Calling venture capitalists - get this thing to market! Read More
