New method traps CO2, rends clean hydrogen and might de-acidify world’s oceans

Hydrogen fuel has been eyeballed by scientists, as well as governments and energy corporations, for many years now as a potential alternative fuel source because of its incredibly high energy. It’s hard to imagine any other non-carbon fuel source capable of driving rockets or high velocity vehicles, like formula 1 sports cars. Besides it being unstable and difficult to extract,

Liquid air could be used to store renewable energy

Renewable energy sources, like wind and solar, are gaining ground fast against fossil fuels in terms of energy production, but unfortunately not that fast as we’d hoped for. One big obstacle in the way of renewable energy is storage. A refined look at an older idea that dates back from the XIX century seeks to address this issue. Namely, engineers

Nuclear energy saves lives – NASA report concludes

Especially after the Fukushima events, nuclear energy has been painted black by most of the media, with everybody suddenly realizing just how dangerous and not really desirable it is. But a recent report conducted by NASA showed that as a matter of fact, nuclear energy leads to substantially fewer pollution-related deaths and greenhouse gas emissions compared with fossil-fuel sources. Even

Quantum dots with nanowires yield greater solar cell efficiency

For some years now, scientists have been exploring the use of quantum dots as the basis for a novel type of solar cell. The advantages over conventional solar photovoltaic cells are numerous, minus one aspect: efficiency, which is actually the most important one. A new technique developed at MIT labs that uses quantum dots in conjunction with nanowires has lead

Nanowires break solar cell cell theoretical maximum efficiency and usher in a new era of solar power

One of the biggest hurdles the solar energy industry currently faces is efficiently transforming the incoming energy from the sun’s rays. Vast fields of solar panels are a common sight, but truth of the matter is their energy output is quite low, which puts them at a technical and economic disadvantage from other renewable solutions and, most important to consider,

Petroleum expert: Our Current Oil Use is “Suicidal Within 1 Generation” – eye opening video

You often hear discussions about how much oil there is still left in the world’s underground. Listen to oil companies they’ll tell you there’s plenty to go around, absolutely no need to worry; listen to fanatic environmentalists and they’ll tell you that in two decades, we’re pretty much screwed. So why not listen to someone not involved in either parties,

Laying a roadmap for future artificial leafs

MIT researchers have published a detailed analysis of all the factors that could limit the efficiency of such a system, basically laying a roadmap for a research program to improve the efficiency of so-called artificial leafs. An artificial leaf has to produce a storable fuel, such as hydrogen, instead of electricity for immediate use; the fuel could then be used

Carbon negative: removing CO2 altogether from the atmosphere

As climate change and global warming become ever pressing issues on the desks of the world’s governments, so do the much awaited measures become more prevailing, albeit not nearly as thoughtfully as they should be addressed. Today, renewable energy sources like solar and wind have actually ceased to become regarded as “alternative”, since actually more capacity of renewable energy was

In Australia, wind power is already cheaper than Fossil fuels; solar is right behind

Australia seems poised to become one of the global leaders in terms of renewable energy; after a study showed that the country could realistically go 100% renewable energy in just 10 years, now, a different study concluded that wind energy is already cheaper than fossil fuels. The research was led by Bloomberg New Energy Finance, and it showed that electricity

Do the math on PV efficiency

I recently came across a great article discussing solar photovoltaic (PV) efficiency. You can read it in its entirety on this website – here’s the gist. When people hear that the typical efficiency for solar power is somewhere around 15%, or even as low as 12% for organic photvoltaics, they scoff and start to mumble that this is much to low

Australia could realistically go 100% renewable energy in 10 years

The only thing that stands between Australia and a future led entirely by renewable energy is the political will to make the change, a new report claims. Australia could be powered entirely by renewable energy in no more than 10 years, using solar and wind energy – two resources which Australia has a lot of. The report was released by

U.S. centered climate change report acknowledges human influence and tells of grim future

A draft released by the U.S. National Climate Assessment reports how human-induced climate change has caused far reaching consequences far dire than previously estimated, affecting all regions of the U.S. “Corn producers in Iowa, oyster growers in Washington State, and maple syrup producers in Vermont have observed changes in their local climate that are outside of their experience,” the report said.

Princeton nanomesh greatly increases the efficiency of organic solar cells

While we all have to recognize the huge potential that solar energy brings us, we also have to say that sadly, so far, we’re not very effective at harnessing this energy. The best modern silicon and indium-tin-oxide-based solar cells are approaching the theoretical limit of 33.7% efficiency. A big breakthrough The team led by Stephen Chou made two dramatic improvements:

Wikileaks reveals US bribes and cyber-espionage stop climate change action

Negotiating an official climate change pact is an extremely high-stake game, not only due to the threats posed to our entire civilization, but also because re-engineering the global economy to a low-carbon model will redirect a massive, multi billion dollar sum towards different sources. Of course, behind all the “save the planet” rhetoric lies the mucky realpolitik: money and threats

Wave-powered swimming robots completes epic 9,000 journey at sea

After it was first cast out to sea less than a year ago from San Francisco’s bay, the PacX Wave Glider, also known as Papa Mau, finally reached the end of its epic journey after it reached Queensland, Australia setting a new world record for the longest distance traveled by an autonomous vehicle. PacX swam over 9,000 miles. Designed for data

Exclusively solar-powered plane will circumnavigate globe in a non-stop flight, even at night

Solar Impulse, the now famous 100 percent solar-powered aircraft, made the headlines after it proved it could fly for 26 hours straight, be it day or night. Now the projects’ initiators want to take the plane and solar power to new dazzling heights – they want to circumnavigate the globe in 20 days and 20 night flight all powered by

Nanoparticle-tech converts solar energy into steam with extreme efficiency

While current solar energy conversion technology is preoccupied with generating electricity with as much efficiency as possible, researchers at Rice University have invented a new technological set-up consisting of nanoparticles smaller than the the wavelength of light that can transform solar energy into steam almost instantly. Their findings show a registered efficiency of 24%, while current solar panel standards range at

World Bank worries about global warming

When the first major talks about global warming began, a top margin of 2 degrees was set for 2100, people slowly understood the globe is warming up much faster than previously expected, so the limit was pushed – first to 3 degrees, now to 4 degrees – and even this isn’t certain.   So heat waves and droughts should be

First wooden wind turbine installed in Germany is a lot more eco-friendly

As of 2010 wind power amounted to 2.5% of the world’s energy production with an estimated 25% increase in quota each year. Yes, eolian  power is one of the cleanest forms of energy production, but like any other renewable sources, its no entirely all green. During a wind power turbine’s manufacturing hundreds of tons of steel are used, which translates

Transparent solar cells could be used onto entire buildings, screens, and more

This has the potential to be the holy graal of solar energy – UCLA researchers have developed a new organic polymer that produces electricity, is nearly transparent and much more resistant than silicone. If you think about solar cells, usually, the blacker the better – the blacker they are, the less energy is lost. But what if we could make
