Drawing inspiration from Mother Nature in designing an ‘artifical leaf’

By - March 26, 2010 2 Pictures
Producing an artificial leaf capable of harnessing Mother Nature’s ability to produce energy from sunlight and water via photosynthesis has been a long-sought goal for researchers aspiring to provide an environmentally-friendly way to free to world of its dependence on coal, oil, and other carbon-producing fuel sources. Now a group of Chinese scientists has presented a design strategy based on the chemistry and biology of natural leaves that could lead to working prototypes of an artificial leaf that captures solar energy and uses it efficiently to change water into hydrogen fuel.

World record 1 megajoule laser shot hits target

By - February 2, 2010 2 Pictures
In their quest to be the first to trigger a nuclear fusion reaction using lasers scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) have delivered more than one megajoule of laser energy to a target. The peak power of the laser light, which was delivered within a few billionths of a second, was about 500 times that used by the United States at any given time and demonstrates the target drive conditions required to achieve fusion ignition.

Honda's next gen solar-powered hydrogen fuel cell station for home use

By - February 1, 2010 2 Pictures
Honda has begun work on a smaller solar hydrogen station prototype intended for use as a home refueling appliance. Capable of an overnight refill of fuel cell electric vehicles it is designed to be a single, integrated unit that will fit in the user's garage. Honda's next generation Solar Hydrogen Station, though not as big as the previous systems, will still produce enough hydrogen (0.5kg) via an eight-hour overnight fill for daily commuting (10,000 miles per year) for a fuel cell electric vehicle.

HH2 hydrogen technology purports to turn any gas-guzzler into a hybrid

By - December 2, 2009 2 Pictures
When the promoters of the HH2 Hydrogen Generator Clean Air Combustion System made an appearance at last year’s LA Auto Show they attracted their fair share of skepticism. Hardly surprising given their claims of boosting the horsepower, performance, and mileage of existing vehicles through the addition of an aftermarket device that mixes hydrogen and oxygen extracted from water with existing fuel. But the naysayers haven’t discouraged the system’s developers as they are fronting up to the LA Auto Show again this year with even loftier claims thanks to improvements to their system. Read More

Ion Tiger sets endurance record for a hydrogen fuel cell powered UAV

By - November 30, 2009 1 Picture
The benefits of using hydrogen fuel cells to power UAVs have been shown by the Naval Research Laboratory (NRL) with its Ion Tiger UAV setting an unofficial flight endurance record of 26 hours and 1 minute while carrying a 5-pound payload. While taking advantage of hydrogen as a high-energy fuel, the electric fuel cell propulsion system onboard the Ion Tiger also boasts the low noise and signature of a battery-powered UAV. Read More

Nissan leases first fuel cell vehicle in North America

By - November 24, 2009 1 Picture
Following on from the successful use of its Fuel Cell Vehicles (FCVs) in demonstration fleets in Japan and California, Nissan has announced its first commercial FCV lease in North America to Sacramento Coca-Cola Bottling Co., Inc. In an advantageous brand tie-in the zero emissions X-TRAIL FCV will be used by the bottler for sales calls and public events in the Sacramento area in promotion of its Coca-Cola Zero soft drink.

Hydrogen fuel cell buses trial set for China's streets

By - November 10, 2009 1 Picture
A team of researchers aims to educate people about the possibilities of hydrogen as a fuel by demonstrating the efficiency of fuel cells in two public transport buses that will operate in China’s North East. The University of Sunderland, UK, has joined forces with Shanghai’s Shen Li High Technology and local experts ComeSys Europe and AVID sustainable vehicles from Cramlington (Northumberland, England) to create ECO2Trans - the region’s first petrol-free passenger buses that will run on a fuel cell, battery and capacitor combination.
