Future cars: Auto bodywork composite doubles as a battery

By Tannith Cattermole

18:41 February 7, 2010 PST

The problem is clear. Hybrid cars and EVs rely on batteries for power, but batteries are bulky and heavy, causing the car to use up more energy. But what if a car's bodywork was made of a strong, lightweight material that could store and discharge electrical energy just as a conventional battery does? In pursuing this goal, researchers at the Imperial College London are developing a key building block for the hybrid car of the future, and the implications go way beyond automobiles - think wafer thin mobile phones and laptops that don't need a separate battery because they draw power from their casing.

Biosensor paper strip test for safe drinking water

By Jack Martin

16:19 January 18, 2010 PST

Engineers at the University of Michigan have developed a strip of paper infused with carbon nanotubes that can quickly and inexpensively detect a toxin produced by algae in drinking water. The paper strips perform 28 times faster than the complicated method most commonly used today to detect microcystin-LR, a chemical compound produced by the blue-green algae (cyanobacteria) commonly found on nutrient-rich waters. Microcystin-LR is among the leading causes of biological water pollution and is believed to be the culprit of many mass poisonings going back to early human history. Read More

This bacteria will self destruct (and improve renewable biofuel production)

By Darren Quick

23:18 December 7, 2009 PST

A key factor is determining the eco-friendliness of any biofuel is how much energy is required to produce it. If the energy expended in producing it, which more often than not comes from fossil fuels, is too high then the environmental benefits of the fuel can be questionable. Researchers have now developed a process that removes a key obstacle to producing lower-cost, renewable biofuels by programming a photosynthetic microbe to self-destruct. Read More

Marine census reveals 17,500 species and counting living in the murky depths

By Sandra Arcaro

23:39 November 30, 2009 PST

“The deep sea is the Earth’s largest continuous ecosystem and largest habitat for life. It is also the least studied,” says Dr. Chris German, who along with hundreds of other Marine Life scientists from around the globe is shedding light on these mysterious depths through an unprecedented census of deep-sea marine inhabitants. Their recordings have yielded astonishing findings of more than 17,500 species of often bizarre marine creatures - from oil-eating tubeworms to elephant-eared octopods - inhabiting the blackest depths between 200 meters and up to 5, 000 meters (~3 miles) below ocean surface. Even more remarkable is the ability of these deep-sea creatures to live and thrive in topographically challenging environments where food availability is marginal, at best. Read More

Thermeleon roof tiles make saving energy as clear as black and white

By Jeff Salton

23:11 November 29, 2009 PST

Simpler, cheaper, biodegradable plastic without using fossil fuels

By Darren Quick

22:32 November 22, 2009 PST

In recent years, polylactic acid (PLA) has attracted attention as a replacement for petroleum-based plastics. It is made from corn-starch, or other starch-rich substances like maize, sugar or wheat, and is biodegradable – reverting in less than 60 days in ideal conditions. PLA is already used as a material for compost bags, food packaging, and disposable tableware, and also for a number of biomedical applications, such as sutures, stents, dialysis media and drug delivery devices. Although its price has been falling, PLA is still more expensive than most petroleum-derived commodity plastics, but now a team of researchers has succeeded in simplifying the production of PLA and making the process much cheaper, meaning we could soon see PLA used in a much wider variety of applications.

New inexpensive method to clean oil from water

By Darren Quick

19:46 November 17, 2009 PST

The rainbow effect caused by varying thicknesses of oil film on water’s surface might be pretty to look at but is indicative of polluted water. This “oil sheen” proves especially difficult to remove, even when the water is aerated with ozone or filtered through sand. But now a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters.

‘Smart Trash’ cash for recycling concept

By Darren Quick

21:52 November 2, 2009 PST

If the benefit to our environment isn’t enough to get some people to recycle, Georgia Tech’s Valerie Thomas has come up with the concept of offering a cash incentive enabled by “Smart Trash”. The concept involves a scanner integrated into a trash receptacle that automatically records what is being disposed of using Universal Product Codes (UPC) or radio frequency identification (RFID) tags attached to the trash. This would not only allow recyclers to better sort the waste but could also provide a cash back channel to consumers recycling goods of value. Read More

By Darren Quick

22:52 October 7, 2009 PDT

Automobiles aren’t the only vehicles turning to more environmentally friendly fuel sources. As we reported recently, NASA are testing a new type of rocket propellant made of a mixture of water and “nanoscale aluminum” powder they claim could provide a cleaner way to launch rockets, power long-distance space missions and generate hydrogen for fuel cells. A number of readers wondered, not unreasonably, what qualifies a rocket fuel as eco-friendly. We now have a few more answers. Read More

Breathing easier could be as simple as crossing the street

By Darren Quick

20:01 October 7, 2009 PDT

Low emission vehicles, such as the Toyota Prius, promise to dramatically cut levels of noxious fumes on city streets. But, until such vehicles start to dominate the roads, people still have to cope with what spews forth from the tailpipes of their fossil fuel-powered cousins. However, researchers have recently found that pedestrians may be able to reduce the amount of traffic pollution they breathe in simply by crossing the street. Read More
