The Circulus concept design by Santosh Chawla

Did you marvel at the impressive cornering and maneuverability of the Dyson Ball when it first raced around the floor in TV ads? If such a ball design can take a vacuum cleaner to places no others would dare to go, what could such a thing could do for a car? Graphic designer Santosh Chawla has incorporated a similar principle into his hydrogen powered Circulus concept car design.  Read More

'A Doctor Examining Urine' by Trophime Bigot - 16th Century...  we've been looking for som...

No-one should ever drink and drive, but there may soon be a good reason to drink a lot before you fill up your car – researchers at Ohio University have worked out a way to efficiently extract hydrogen from urine. It could provide a cheap, renewable fuel source for vehicles and, finally, a good use for the most abundant waste on Earth.  Read More

The hydrogen-powered Riversimple prototype makes its debut

The Riversimple Urban Car, a hydrogen-powered two-seater capable of speeds up to 50mph and of traveling more than 200 miles without refueling, was unveiled in London this week. While the prototype car is itself a welcome development in sustainable travel, the aim of the company behind it is even more ambitious: to completely eliminate the environmental impact of personal transport.  Read More

An environmentally friendly step in the right direction - Sony's mercury-free batteries.

It’s no secret that mercury is a dirty word in environmental circles, and more of the big guns of electronics are starting to take note. Apple's MacBook Pro now features a mercury-free backlight display, and Fuji has released its eco-friendly EnviroMax batteries. This week Sony has strengthened its enviro-credibility by announcing a line of mercury-free alkaline button batteries.  Read More

Aeropak fuel cell provides four times the power of advanced lithium batteries

Horizon Fuel Cell Technologies latest hydrogen fuel cell release is designed as a drop-in replacement for battery packs used in small electric Unmanned Aerial Systems (UAS). Weighing 4.4lbs (2kg) and storing 900Wh of usable electric energy, the Aeropak can to increase flight endurance by up to 300% over lithium batteries, meaning longer range missions and more energy to run on-board cameras and sensors.  Read More

Mercedes-Benz F-CELL Roadster

When studio shots emerged of the Mercedes-Benz F-CELL Roadster design study last month, it wasn't something we were necessarily expecting to see out-and-about. The curious mixture of early automotive design elements and 21st Century technology stretched its legs (at a top speed of 25kmh) by covering a section of the historic route taken by Bertha Benz more than 120 years ago in a Benz Patent Motor Wagon.  Read More

Mazda's Premacy Hydrogen RE Hybrid

Mazda is providing another green option in Japan by commencing commercial leasing of their Premacy Hydrogen RE Hybrid, a hydrogen hybrid vehicle that combines Mazda’s hydrogen rotary engine with an electric motor. The Premacy Hydrogen RE Hybrid improves on the RX-8 Hydrogen RE – the first model to be commercialized - with the hydrogen fuel range of the doubled to 200 kilometers and the maximum output increased by approximately 40 percent to 110 kilowatts.  Read More

Showing effects of damage to hair by regular bleach.

March 30, 2009 It's not the first area that springs to mind when you think "green research", but a natural alternative to regular hair bleach may have been discovered. For everyone who consistently bleaches their hair with hydrogen peroxide, risking the healthy sheen of the hair is just part and parcel. However, Japanese scientists have come up with a possible alternative that could achieve the same result without the damage.  Read More

New Holland's prototype NH2 hydrogen powered tractor

Tractors may not be the sexiest of vehicles, and they probably aren’t the first ones that come to mind when thinking about environmental friendliness, but agricultural equipment manufacturer New Holland is looking to change that with the production of a prototype tractor that is powered by a hydrogen fuel-cell.  Read More

People are becoming more and more reliant on the portable gadgets they carry every day and at no time is that reliance more pronounced as when those gadgets’ batteries run out of juice. While we’ve seen some fuel cell technologies appear in recent years that offer the future prospect of powering portable devices, none are quite as small as this new working fuel cell created by US chemical engineers and featured recently in New Scientist that measures just 3 millimeters across.  Read More
