Methane

A team of researchers from MIT may have found new evidence to shed light on the cause of the most devastating mass extinction in the history of our planet. The event, estimated to have taken place around 252 million years ago, was responsible for the extinction of roughly 90 percent of all life on Earth.  Read More

Harvard's soft-bodied robot jumps up to 30 times its own height using internal gas explosi...

Most robots are built out of rigid materials, but a DARPA initiative to build soft-bodied robots that can squeeze into hard-to-reach places has led to the development of new types of the mechanical marvels. Harvard's Whitesides Research Group is working on a soft-bodied solution and has produced a squishy three-legged bot that can jump 30 times its height using the power of internal explosions.  Read More

Artist's concept of SpaceX Mars landing (Image: SpaceX)

Elon Musk, founder and CEO of SpaceX, says that the missions to Mars by his company will use rockets powered by methane, which can be manufactured on the Red Planet. The announcement came last as the South-African born entrepreneur was giving a lecture in November to the Royal Aeronautical Society in London, where he was presented with the Gold Medal – the society’s highest award.  Read More

The pilot plant in Stuttgart that makes biogas out of waste from wholesale markets (Photo:...

Some readers might remember the Mr. Fusion unit in Back to the Future that Doc Brown fills with household garbage, including a banana peel and some beer, to power the iconic time-traveling DeLorean. While we're still some way from such direct means of running our cars on table scraps, researchers at Fraunhofer have developed a pilot plant that ferments the waste from wholesale fruit and veg markets, cafeterias and canteens to make methane, which can be used to power vehicles.  Read More

The Philips bio-light is 'powered' by glowing bioluminescent bacteria

The search for greener, more power-efficient lighting systems won't stop with compact fluorescents and LED systems if Dutch electronics giant Philips has anything to say about it. In an effort to embrace a truly natural approach to lighting, the company took a cue from fireflies and deep-sea creatures to create a (literally) green light powered not by electricity or sunlight, but by glowing bioluminescent bacteria.  Read More

In many parts of the world the absence of sanitary waste disposal is not just inconvenient...

Whatever you call it - lavatory, privy, latrine, crapper, loo or dunny - most of us take the humble toilet for granted. But in many parts of the world the absence of sanitary waste disposal is not just inconvenient, it can cause deadly diseases such as hepatitis, dysentery, trachoma, typhoid and cholera. Enter Marc Deshusses, a Duke University environmental engineer who has envisioned an innovative yet simple waste disposal system designed specifically for Third World countries that can be constructed from everyday items. Now, as part of a broad ranging project funded by the Bill and Melinda Gates Foundation, Deshusses has received $100,000 to perfect and test the system in the laboratory before producing a prototype to field-test in 18 months time.  Read More

A recent study suggests that the methane gas generated by biodegrading alternatives to tra...

As tons of plastic items continue to take up space in landfills, and the floating Great Pacific Garbage Patch continues to grow, environmentally-conscious consumers are understandably becoming more interested in biodegradable alternatives to traditional plastic. Whether it's because they share these concerns, or are just trying to cash in on an "eco-fad," many companies have responded by producing biodegradable versions of formerly near-eternal plastic products. While biodegradable products are designed to reduce the amount of trash clogging up our waterways and spoiling our parks, at least one scientist believes they may ultimately be doing more harm than good.  Read More

The new biogas plant, sited next to the Didcot sewage works in Oxfordshire, has been offic...

The biomethane project that turns human waste into green gas that we featured in May has now gone live. The project is now converting the treated sewage of 14 million Thames Water customers into clean, green gas and is pumping that gas into people's homes.  Read More

Dry water has been found to have several potential environmentally-friendly uses

You know, I’m pretty sure I remember a Far Side cartoon or something, where someone was selling powdered water – “Just add water!” Well, dry water isn’t quite the same thing. It’s 95 percent liquid water, but that water takes the form of tiny droplets each encased in a tiny globe of silica. The resultant substance is dry and granular. It first came to light in 1968, and was used in cosmetics. More recently, a University of Liverpool research team has been looking into other potential uses for the substance. They have found several, but most interesting is its ability to store gases such as carbon dioxide.  Read More

A novel process uses rocket thrusters to clean up waste water and power treatment plants (...

Rocket engines are generally not thought of as being environmentally-friendly, but thanks to a newly-developed process, we may someday see them neutralizing the emissions from wastewater treatment plants. The same process would also see those plants generating their own power, thus meaning they would be both energy-neutral and emissions-free. Developed by two engineers at Stanford University, the system starts with the formation of nitrous oxide (N2O) and methane gas - something that treatment plants traditionally try to avoid.  Read More
