Marine Corps Plan to Deploy Through Space

After three years of being laughed out of meetings, the US Marine Corps’ futuristic plans to deploy through space may finally be getting some traction. The Marine Corps calls the concept the Small Unit Space Transport and Insertion Capability (Sustain). This plan, a growing group of Marine supporters say, is the natural evolution of the service’s proclivity for expeditionary warfare that began decades ago with amphibious landings. The concept is to deliver strategic equipment or a small squad of soldiers to any point on the globe — even the most hard-to-reach location — within hours of need. Once on the ground, those soldiers can carry out strategically critical missions like reconnaissance or destroying a specific target. At least, that’s their pitch — via Defense Tech

Microreactors Change Propane into Hydrogen

Microreactors have already been used for on-site reforming of fuels, such as methanol or propane, to produce hydrogen to be used in fuel cells. Now, researchers at the University of Illinois at Urbana-Champaign have designed very efficient ceramic microreactors to do this task. The scientists say that their microreactors are much better than other fuel reformer systems. They are now trying to reform gasoline and diesel, which are more widely distributed than propane — via Slashdot

100% of Scottish Power Green by 2050

All Scotland’s electricity needs could be met from renewable energy sources by 2050 under a bold vision for a greener future unveiled yesterday by Nicol Stephen, the deputy first minister. In an hugely ambitious pledge, the leader of the Scottish Liberal Democrats vowed to go further than the Executive’s existing commitment to meet 40 per cent of the country’s electricity requirements through renewable sources by 2020

‘Laser Chips’ Could Replace Wires in Your PC

Researchers from Intel and the University of California at Santa Barbara have found a way to build low-cost laser chips that could eventually shuttle data around PCs at much higher speeds than today’s copper wire interconnects. The researchers combined the properties of a compound semiconductor material called indium phosphide, which emits light constantly, and silicon, which can be used to amplify and direct that light. They sandwiched the materials together to create a single device that can be manufactured using standard chip-making techniques

Plastic Batteries Coming Soon?

Engineers at Brown University have built a prototype of a hybrid plastic battery that uses a conductive polymer. The system, which marries the power of a capacitor with the storage capacity of a battery, can store and deliver power efficiently. For example, during performance testing, it delivered more than 100 times the power of a standard alkaline battery. Still, it’s unlikely that such a device can appear on the market before several years

How Many Lightbulbs Does it Take to Change the World?

In the next 12 months, starting with a major push this month, Wal-Mart wants to sell every one of its regular customers — 100 million in all — one swirl bulb. In the process, Wal-Mart wants to change energy consumption in the United States, and energy consciousness, too. It also aims to change its own reputation, to use swirls to make clear how seriously Wal-Mart takes its new positioning as an environmental activist — via meta-roj blog

Tumour-Suppressing Gene Contributes to Ageing

Scientists have discovered a tumour suppressing gene which also leads to ageing in stem cells. The gene also known as p16INK4a when removed from knockout mice resulted in older mice having organs as healthy as younger ones. However they didn’t live any longer than normal mice. The new study was confirmed by three independent researchers from Harvard, UNC Chapel Hill and University of Michigan

Vaporising Garbage to Create Electricity

Geoplasma is planning to build a power plant in St Lucie County, Florida that will generate electricity by vaporising landfill trash and sewage treatment plant sludge with plasma arcs. It will be the first plant of its kind in the USA and the largest in the world. The power plant is expected to destroy 3000 tons of garbage, generating about 120 megawatts of electricity per day. The plant will also supply steam to a nearby Tropicana juice plant. The landfill is expected to be depleted in about 18 years. In addition, up to 600 tons of melted, hardened sludge will be produced each day and will be sold for road construction
