Shocking USGS Image Shows How Much Potable Water We Actually Have Available

Posted by Ovidiu Sandru in Green News on May 14, 2012

The USGS (United States Geological Survey) has published a post on their water-related website that shows an amazing 3D rendering of actually how much water exists on Earth and how much of that water is potable. You can see the results on the left – they shocked me. The blue sphere floating above the Earth [...]

Asteroids Could Be Future Source of Water and Precious Materials

Posted by Mihai Sandru in Green News on April 27, 2012

Some would say it’s a long shot, some that it’s pure science fiction, but the challenge is on: mining asteroids for water, platinum, nickel and iron has never seemed more real than now! The initiative belongs to Google founders Larry Page and Eric Schmidt and X-Prize creator Peter Diamandis. With the hovering threat of resource [...]

“Oil, not Alternative Energy, is the Future…”

Posted by Ovidiu Sandru in Green News on April 25, 2012

Usually I look for and read stuff related to alternative energy, electric cars, things that aren’t that obtrusive to the environment and that don’t harm our children and our planet’s future health. I have never thought for one second that in the 21st century someone can say: “Oil, not Alternative Energy, is the Future” For [...]

African Underground Contains Enough Water for 9 Billion People

Posted by Boniface Ndirangu in Green News on April 24, 2012

Reuters reported on Friday that there are huge underground water reserves in some of the driest parts of Africa. This could provide a buffer against climatic change challenges for years to come. There are large aquifers, or underground water sources, that the researchers mapped. This was a pioneering project by the British Geological Survey and University [...]

Jadav Payeng – The Heroic Man Who Grew a Forest

Posted by Mihai Sandru in Green News on April 5, 2012

Who needs Superman when we have our own, daily heroes? It’s true, they don’t have as much power, but the efforts they undertake every day makes them worth mentioning… Or writing about, as it’s the case: meet Jadav Payeng – the man of the hour now in India. He has no X-ray vision and he’s not [...]

New Cerium Oxide CO2-Adsorbing Material Created by Hitachi 13 Times More Efficient

Posted by Ovidiu Sandru in Green News on April 3, 2012

A new CO2-adsorbing material based on cerium oxide has been created by Hitachi. It has been designed to capture the CO2 produced by coal-fired plants and the company says it’s 13 times more efficient than old zeolitic solid adsorbents. Because old materials adsorb moisture existing in the gas, they’re not very good at separating CO2 [...]

New Way of Recycling Plastic Discovered by ORNL Scientists

Posted by Mihai Sandru in Green News on March 31, 2012

For the recycling fans but not only, there’s a new way of recycling plastic. Actually, just the plastic bags, but it’s a start! Researchers at the Oak Ridge National Laboratory have come a long way – they now take the polyethylene out and turn it into carbon fibers, universally useful. According to the researchers, the [...]

MIT Finds How Carbon Dioxide Could Be Sunk Into the Ground Forever

Posted by Ovidiu Sandru in Green News on March 21, 2012

Deep saline aquifers in the U.S. could be the solution for storing the CO2 outputted from coal power plants in the long run, thus making them cleaner and the energy cheaper. It’s not that I turned into preaching people how to get along with coal (again), but the solution really sounds simple and, if it’s [...]

Bill Gates’ Fecal Recycling Technology Studied by UK Universities

Posted by Mihai Sandru in Green News on March 16, 2012

Now don’t be grossed out, but it seems human fecal waste will actually be useful to something – obtaining hydrogen and even water to drink out of it! The bold initiative belongs to a team of researchers from Imperial College London, the University of Manchester and Durham University, who received the funds from the Bill [...]

New Discovery Shows That Spider Silk Conducts 800 Times More Heat

Posted by Mihai Sandru in Green News on March 8, 2012

Are you afraid of spiders? Disgusted when running into spider webs? Well, you shouldn’t – they actually have great applications, among the latest being an outstanding heat conductor. This strange discovery has been made by the Iowa State University researchers, who found that spider silk conducts heat a whopping 800 times better than any other [...]

Future Aircraft to Become More Fuel-Efficient Thanks to Regenerative Braking

Posted by Mihai Sandru in Green News on March 2, 2012

If you fly pretty often, you’re going to like this a lot. Again, if you’re living near an airport, you’re going to dig this even more. I’m talking about planes powering themselves and thus making for a cheaper ticket or a less noisy airport. How is that possible? Well, maybe few of us knew that [...]

Bacteria Living in Stratosphere Could Make for Better Microbial Fuel Cells

Posted by Ovidiu Sandru in Green News on February 28, 2012

Newcastle University researchers have discovered that Bacillus stratosphericus, a bacterium that usually lives in the stratosphere (as its name suggests) could be used to generate electricity in microbial fuel cells. It’s not that microbes hadn’t been used before this discovery – it’s the fact that this particular type of bacteria can double the output of a [...]

16 Hydrogen Fuel Cell Vehicles Acquired by U.S. Military

Posted by Mihai Sandru in Green News, Hydrogen Power on February 25, 2012

There’s all this talk about hydrogen fuel cell cars, but maybe nobody thought it would go that far: now the US military has them! It’s the first army in the world to include a fleet of 16 such vehicles and test them in a Hawaiian environment of real-life conditions. These tests will make the vehicles [...]

Cincinnati One Step Closer to Be Powered Entirely by Renewable Energy

Posted by Mihai Sandru in Green News on February 20, 2012

We’ve gone over from baby steps – supplementing the electrical grid – to powering an entire 300,000 people with renewable energy. It’s not happening yet but it’s in the works: by summer, the people of Cincinnati could be having this type of energy coming into their homes without paying extra. It’s a big change, since [...]

How EcoTricity's Sea Raiser Project Harvests Seawater Energy

Posted by Mihai Sandru in Green News on January 27, 2012

Electricity obtained from sea water is one of the most reliable clean sources of energy and now it’s set to become one of the most affordable ones. The proof lies in the SeaRaser project, belonging to the UK alternative energy company Ecotricity – more low-cost even than fossil fuels. Devon Energy engineer Alvin Smith is [...]
