A day after Playstation announced that their players are finally getting an update
which will allow them to quickly switch from Rest Mode to powered-up, a feature already available on Xbox, the Natural Resources Defense Council announced that Xbox players are killing Gaia
The solar eclipse due to cover much of Europe on March 20 will be the continent’s first for 16 years.
Back in 1999, as people stopped staring at the sun and got back on with their day they caused a power surge which still stands as a UK record – greater than anything after a football match or royal wedding.
Planning permission has been given for what could become the world’s largest offshore wind farm on the Dogger Bank, off England’s east coast.
If fully constructed, the project will have up to 400 turbines with a total generation capacity of 2.4 GW. That’s enough to power 1.9 million households – more than Manchester and Birmingham combined.
The search for alternative energy sources in the age of climate change has overlooked tidal energy: a vast and unexploited worldwide resource.
For three decades now, tidal lagoon schemes have been recommended as an economically and environmentally attractive alternative to tidal barrages. More recently, two proposals for tidal lagoons in Swansea Bay, Wales have emerged and there have been several reports documenting how such a project there could have the potential to harness significant energy resources.
Walmart, Costco and other 'big box stores' or facilities like hospitals could use a fuel cell that runs off the natural gas that already flows in pipelines below city streets and eliminate the electricity 'middle man', which is good for the environment.
Instead of drawing electricity from the power grid, that often ends up being converted from coal, natural gas or nuclear power, facilities could instead go direct and use natural gas-powered solid oxide fuel cells. It would lower their electric costs, increase power reliability and reduce greenhouse gas emissions, according to a cost-benefit analysis.
From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets' versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome. In the journal ACS Nano, scientists report the first durable, flexible cloth that harnesses human motion to generate energy.
It can also self-charge batteries or supercapacitors without an external power source and make new commercial and medical applications possible.
Sewage sludge, green waste, even animal excrement can be utilized for energy recovery with the biobattery modular concept.
Biogas plants are an important element for decentralized energy supply. They produce electricity from renewable resources and can compensate for highly fluctuating wind and solar energy. There are already 8,000 plants in operation in Germany with an electrical output of 3.75 gigawatts in total, that is the equivalent to roughly three nuclear power plants. However, the plants have several disadvantages too: they only process a limited range of organic substances and are in competition with the cultivation of food plants.
Stockholm is considered the world's most sunlight-deprived capital - in November of 2014 the Swedes living there had just a few hours of the stuff and in winter months, it will get dark at 3 PM anyway, so if the sun is hidden by clouds, it can be a real downer.
Yet not everywhere in Sweden is so bleak. Because there are so few solar laboratories in the world, KTH Royal Institute of Technology reasoned that Stockholm was the perfect place to build one and in there, the future is bright 24 hours a day.
Harvesting sunlight is old technology for plants but it's a level of efficiency in solar energy we would love to be within a billion years of - artificial photosynthesis is needed if we want to go beyond the energy density of things like combustion engines.
