SOHH: Solar human hybrid transport for the whole family (and the dog)

By Paul Ridden

02:36 June 19, 2009 PDT

If the words "human hybrid" conjure terrifying images of Christian Bale battling it out against Skynet and a league of Terminators then the Solar Human Hybrid Project (SOHH for short) might come as a bit of light relief. It's a one of a kind, great-looking 4-wheeler where the power comes courtesy of the harmonization of solar energy and a good old-fashioned lower body workout. There's an iPod dock, a GPS navigation system, a cargo area and even a platform especially for the dog. It's definitely a worthy contender for the crown of coolest green transportation around. Oh, and it's also a school project. Read More

Plastic and fuel that grows on trees

By Darren Quick

18:19 May 20, 2009 PDT

Biofuels continue to steal the spotlight when it comes to the search for a renewable, environmentally friendly replacement for crude oil. While that’s understandable when considering the transport industry, but crude oil is also used in the production of conventional plastics and chemical products such as fertilizers and solvents. Now chemists have learned how to convert plant biomass directly into a chemical building block that can not only be used to produce fuel, but also plastics, polyester and industrial chemicals cheaply and efficiently.

Smarter wind technology looks to improve turbine workrate

By Karen Sprey

18:20 May 10, 2009 PDT

Clean, renewable energy is freely available – in the form of wind, sun and water. However, harnessing it reliably and cost-effectively remains a barrier. Wind power is one of the fastest growing alternative energy markets and researchers at Purdue University and Sandia National Laboratories in West Lafayette, Indiana, are working to make wind turbines more efficient, reliable and resilient.

Febot uses wind power to recharge batteries

By Karen Sprey

15:08 February 23, 2009 PST

We're always on the lookout for new, ‘greener’ ways of saving or renewing energy. South Korean designers Ji-yun Kim, Soon-young Yang and Hwan-ju Jeon have developed the Febot, a small, easily-assembled portable battery charger concept that harnesses the power of the wind rather than using electricity. Place a rechargeable battery inside the Febot and stick it on the outside of a window or wall, or any other outdoor surface, using the suction cap at the base of the unit. Read More

Smart Lite CFL replaces the bulbs not the ballast

By Karen Sprey

21:42 February 17, 2009 PST

Compact fluorescent lights (CFL) are a smaller version of their long established big brothers which, despite some drawbacks such as a small amount of mercury content, have gained serious ground in recent years as an energy-efficient alternative to conventional incandescent globes. CFLs reduce carbon emissions because they convert electricity into light more efficiently and also last up to ten times longer, but the globe still reaches its used by date long before the base (ballast) section that connects it to the power socket. 3E Technologies has identified this as another wasteful aspect of the process that could be eliminated and its solution is the Smart Lite - a two-piece CFL which allows the bulb to be removed from the ballast and replaced with a simple ‘insert and twist’ operation.

EBDI ethanol engines surpass gasoline engine efficiency

By Mike Hanlon

18:30 February 6, 2009 PST

Automotive technology specialist Ricardo has revealed the development of technology that optimizes ethanol-fuelled engines to a level of performance that exceeds gasoline engine efficiency and approaches levels previously reached only by diesel engines. The technology, called Ethanol Boosted Direct Injection (EBDI), takes full advantage of ethanol’s best properties – higher octane and higher heat of vaporization – to create a renewable fuel scenario that is independent of the cost of oil.

Making waves work: the Searaser hydro-power system

By Noel McKeegan

22:48 November 26, 2008 PST

Our second ingenious example of bringing new approaches to hydro-power generation for the week, SEARASER works on the conventional principle of using water pressure to drive turbines but achieves this in a unique way. The system consists of a tethered wave energy converter which uses the rolling motion of waves to pump water to higher ground on-shore from where it can then be stored and used to create electricity on demand.

Light powered motor utilizes shape-shifting plastic

By Darren Quick

04:34 July 28, 2008 PDT

A research team at the Tokyo Institute of Technology has developed a plastic motor that is powered solely and directly by light. Unlike solar-powered motors, which use photovoltaic cells to convert light to electric power and therefore require wires and batteries to deliver and store the power, the light activated motor converts light directly into mechanical energy. The first of its kind motor achieves this by using a belt made from a special elastomer whose molecular structure expands or contracts when illuminated, depending on the wavelength of light. An 0.08-millimeter thick belt coated with the shape-shifting plastic is able to turn a pair of wheels measuring 10 millimeters and 3 millimeters in diameter at 1 rpm, and although the device is still quite inefficient in terms of converting light into energy at this stage, the idea throws up an amazing number potential applications.

Falx Air unveils multi-purpose hybrid aircraft design

By Noel McKeegan

16:21 June 25, 2008 PDT

It's safe to say that there is a transport revolution underway. Driven by the need for cleaner, more efficient and more versatile vehicles, it's delivering an unprecedented number of radical and innovative designs for the road, sea, and for the air. The latest airborne example to come to our attention is this Hybrid Transport Aircraft design from Falx Air. In addition to being used as a standard light cargo platform, mid-air light re-fueling or surveillance aircraft, the Very Light Hybrid Transport (VLHT) can be adapted to carry six passengers, or four stretchers and two medical staff. Like the company's hybrid-electric tilt-rotor aircraft platform unveiled earlier this year, the design combines automotive hybrid electric technology with a fast charge battery system and solar cells to deliver exceptional fuel economy.

London's famous coal power station about to get new, green lease on life

By Loz Blain

22:51 June 24, 2008 PDT

June 25, 2008 A controversial development proposal now under consideration aims to turn London's iconic but defunct Battersea Power Station into a carbon-neutral biofuel power plant. The proposal also includes a 300 meter-tall residential tower featuring solar powered climate control and a glass 'eco-dome' that would allow residents to grow tropical roof gardens even in London's distinctly non-tropical weather. But is it a revolutionary plan to revitalize an old collapsing fossil fuel plant with a new green lease of life, or simply a grandstanding attempt by a property developer to build an ultramodern skyscaper in old London town?

Two-mile high termite nest proposed to counter the population challenge

By Loz Blain

18:01 May 4, 2008 PDT

May 5, 2008 Forward-thinking architects are looking upwards in an effort to control a global population that is growing by around 2.2 per cent every year and becoming ever more concentrated in crowded cities. Eugene Tsui is taking nature as the inspiration for his 2-mile high, one-mile wide Ultima Tower, capable of housing up to a million people. Designed to be virtually impervious to wind, water and earthquakes, the massive tower is conceived less as an architecture project but as a series of mini-ecosystems within which other architectural projects can be developed. And it offers some ingenious ideas on energy production, water use and intra-colony transport. At US$150 billion a pop, you wouldn't expect to see the Ultima being built any time soon, but as population pressure increases, it's pioneering ideas like these that will form the inspiration for real-world solutions.
