The electrical inlet
By Darren Quick
22:13 March 18, 2009 PDT
It wasn’t surprising to see that power conservation was a prevalent theme for entries in this year’s core77 Greener Gadgets Design Competition – the first two places were taken by variations on household power meters. One of the entries that made it to the semi final stage that we thought warranted some kudos was the Inlet ‘Outlet’ - a concept that would see household electrical outlets accompanied by an electrical ‘inlet’ that would make it easy for householders to feed power back into the power grid.

World's first all-electric 24-hour endurance motocross race to be held in California
By Loz Blain
20:36 March 18, 2009 PDT
When the flag drops, the bullsh*t stops, as they say in racing, and few sectors in the auto market have as much to prove as electric motorcycles. The performance potential of electric bikes is almost unbounded, with massive advantages over petrol bikes in so many areas - and battery technology is starting to catch up with the market's needs - but until recently, there's been no international competitive showcase for the top level of electric motorcycles. Just this week, the FIM announced a zero-emissions TT Grand Prix on the Isle of Man in June - and paved the way for electric bikes to compete in the future against top-level petrol bikes. Now, off-road specialists Zero Motorcycles are gearing up for the world's first all-electric 24-hour endurance motocross race in California on April 4. The flag has dropped on electric racing. Time to see who's got the goods, and who's been telling porkies. Read More
Movito: modular, hubless electric scooter design
By David Greig
19:03 March 18, 2009 PDT
March 19, 2009 We live in a world where the need for lighter, more efficient vehicles is glaringly apparent, and in recent times designers and automotive manufacturers have ramped up their efforts to meet this challenge. Given this climate it's not surprising to see the enviro-conscious "Movito" scooter design receive accolades in the Create the Future Design Contest. Engineer/Designer Tiam Chiem's Movito is a 2-modular design consisting of an upper scooter chassis and the base which provides the drive via an in-wheel electric motor and hubless front wheel. The modular design allows a range of possible morphs, including multiple bodies to be connected to the base or two bases to be connected in parallel to form a two-seater. Read More
Don't be a pig with your power usage
By Jude Garvey
00:27 March 18, 2009 PDT
Educating children about power usage can be a difficult task. It’s not easy explaining the concept of electricity to a five year old, let alone the fact that we have to pay for it. This cute little pig might help to solve this problem and monitor television and game usage at the same time. Power Hog is a power-consumption meter design concept in the form of a green and silver piggy-bank. You simply plug the tail into the power outlet and the snout into the electric device, feed in some coins and this little piggy does the rest. When the Power Hog is connected the dollar sign glows green, it fades when there is sufficient credit and alerts you that money is running low by blinking red. Read More
Koenigsegg Quant: 512 bhp 275 km/h, solar-electric 4-seater
By David Greig
20:25 March 5, 2009 PST
Swedish supercar manufacturer Koenigsegg, in conjunction with NLV Solar of Switzerland, is showing its full scale four-seater NLV Quant at the 2009 Geneva Salon.

Magenn floating wind generators take advantage of high altitude winds
By Loz Blain
16:15 February 26, 2009 PST
Wind power is notoriously flighty, particularly at ground level. Most turbine-on-a-post wind powered generators operate at around 20-40% of their rated generation capacity, simply because wind is intermittent and changes direction. But a generator situated 500-1000 feet above ground level would enjoy much more consistent strong wind - which is why the Magenn MARS system makes so much sense. It's a helium-filled rotating airship that spins in the wind on the end of a variable-length tether that also acts as a power transmitter, and it's expected to operate at more like 50% of its rated capacity. Each MARS system will be cheap and portable, which will make them extremely useful in rural, camping and emergency situations. A prototype has successfully been flown in North Carolina. A great idea that makes economic sense. Read More
World’s first electric hybrid sports boat
00:41 February 26, 2009 PST
The low-emissions, fuel-saving benefits of hybrid technology aren't limited to the freeway and systems incorporating electric propulsion are popping up in all areas of transport. On the water we've seen hybrid tugboats and solar hybrid motor-yachts, but this is the first time we've seen hybrid technology in a speedboat. Billed as a world's first electric hybrid sport boat, EPIC Wakeboats EPIC 23E relies entirely on a silent, emissions-free electric motor for propulsion and uses half the fuel and produces half the emissions of its combustion-powered equivalent.

By Darren Quick
16:19 February 25, 2009 PST
Toyota is taking the concept of green cars literally with the development of a hybrid concept car made from seaweed which will to be shown at the Melbourne International Motor Show in Australia this week. The 1/X (pronounced one-Xth) gets its name because it envisages a hybrid-powered car of the future with a fraction of the environmental footprint of today's cleanest cars. Read More
Green Wheel - 3 in 1 wireless electric bicycle hub motor
By Paul Evans
21:01 February 23, 2009 PST
A fully self contained bicycle hub motor known as the GreenWheel has been developed by students at MIT that contains the motor, batteries and motor controller all within the hub enclosure. Very similar in concept to the E+ we reported on earlier this week, but taken one step further by combining the batteries together with the motor in a single hub instead of putting the batteries in the front hub and motor/controller in the rear hub as on the E+.

E+ Electric Bike - the world's most advanced electric bicycle?
By Paul Evans
18:42 February 22, 2009 PST
With the increasing popularity of the electrically assisted pushbike we are starting to see some innovative designs hit the market. While hub motors are the number one solution for mounting the electric motor within a bike frame, either in the front or rear wheel, mounting the battery pack and motor drive electronics has remained a challenge when taking into consideration practically and aesthetics. The folks at Electric Motion Systems think they have the answer with a combination of a 750 watt rear wheel mounted hub motor with built-in motor drive electronics paired with a battery pack mounted in the front wheel hub.

Chevy Volt to get energy efficient Bose sound system
By Darren Quick
19:20 February 11, 2009 PST
It’s obvious that car manufacturers working to provide consumers with environmentally friendly vehicles must deal with power, weight, and space constraints to make the next generation of automobiles a reality. What isn’t so obvious is that manufacturers of in car systems will also need to address these constraints, which is the reason Bose has been working on a new sound system that utilizes a proprietary design to produce a system that is 30% smaller, 40% lighter, and uses 50% less energy than conventional Bose sound systems, while still delivering premium, high-quality audio. Bose will debut its Energy Efficient Series sound system in the Chevy Volt, which is set to hit showrooms in 2011. Read More
Foiljet MR1 hydrofoil: the motocross bike for water
By Paul Evans
00:55 February 10, 2009 PST
The Foiljet MR1 is a new personal watercraft concept that takes the best features of a motocross bike and jetski, throws in two hydrofoils plus a silent, energy efficient electric motor to create what would have to be a surefire recipe for outrageous fun. The design looks something like a motocross bike, but instead of wheels there are beams with small hydrofoil wings mounted at the ends that can be raised or lowered. The concept would use a 15 kW (20 hp) electric motor housed at the end of the rear beam with its instant electric torque lifting the craft out of the water to become "foil borne". Read More
Thermoelectrics to replace car alternators and improve MPG
By Paul Evans
16:06 February 8, 2009 PST
Thermoelectrics - the phenomena in which a temperature difference creates an electric potential - have been known about for almost 200 years, but practical applications have not been widespread due to their low energy efficiency. That may all now be about to change as Germany automakers Volkswagen and BMW have developed thermoelectric generators (TEG) that recover waste heat from a combustion engine. Read More
Electric garbage truck is powered by garbage
By Loz Blain
01:08 February 5, 2009 PST
Mr. Fusion it ain't, but in what is believed to be a world first, a small town in the UK has debuted an electric municipal garbage truck that's powered by the garbage it collects. Kirklees council has deployed a modified Ford Transit with a 40kWh lithium-ion battery pack as its first silent garbage truck - and the trash it collects is burned back at the Energy from Waste center, generating enough energy to recharge the truck's batteries and pump another ten megawatts back into the power grid.

US$3 LED light bulb lasts 60 years, could end battle of the bulbs
By Paul Evans
17:44 February 1, 2009 PST
Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost just GBP2 (USD2.80) and last up to 60 years. The gallium nitride based bulbs are 12 times more efficient than conventional tungsten incandescent bulbs and three times more efficient than compact fluorescent low-energy bulbs. As well as lasting 100,000 hours, ten times as long as today's eco-bulbs, the LED bulbs do not contain mercury, so disposal is less damaging to the environment, they do not flicker and fully illuminate instantly, unlike the current generation of eco-bulbs.

Roofus robot scours rooftops for snow
By Kyle Sherer
17:10 February 1, 2009 PST
Here's an interesting idea for those readers out there facing bleak winter conditions to ponder. The Roofus robot concept will diligently wipe snow from rooftops, carting loads of up to 250kg to the edge and dumping it over the side. And though the concept designed by Michal Glogowski is primarily intended for work on icy surfaces, it can also be fitted with lawn mowing blades and sweeping attachments, making it a useful design throughout the whole year.
