You’ve heard of the Wonder Bra? Well, this is the wonder bag. Wonderbag,
to be specific. It’s a slow cooking bag, a new invention with old
roots, one that is bringing tasty dishes and energy savings to us in the
western world, while doing the same for poor, rural African
communities.
It is not as simple as that, but close. A new study has introduced the concept of "metamaterial analog computing", where metamaterial blocks that can perform mathematical operations (such as spatial differentiation, integration, or convolution) by propagating light waves into them. This discovery is important as it can provide new computing systems much thinner than the conventional lens-based optical signal and data processors.
Nissan and FedEx are keeping their tests of the new e-NV200 van and the next stage is Brazil. e-NV200 is 100% electric and will be delivering FedEx packages for a month. The obtained results will then be analyzed by the two companies and used to perfect e-NV200 plans, which production will start latter this year in Spain.
We use massive amounts of batteries these days to power everything from flashlights to cars. The used batteries are toxic and end up dumped into landfills daily. The time is long overdue to come up with a biodegradable battery that would work in most devices. That time finally seems to be on its way as scientists work to bring a battery powered by sugar to the public.
Geothermal heat pumps are a cost- and energy-efficient way to stay warm during the long, cold months of winter. They have been around since the late 1940s, but as the technology gets better and the prices continue to fall, they have recently become more popular for home use. Today, about 80,000 geothermal heat pumps are installed per year in the United States. Here’s how geothermal heat pumps work — and how you can get one for your home.
In what will be the largest gathering on sustainability ever to be held in the Middle East, innovators from many sectors will gather in Abu Dhabi on January 18 – 25. Abu Dabai Sustainability Week features the World Future Energy Summit and brings together leaders from the worlds of politics, science, business, and academia to discuss and address the energy challenges of the future. Read on to learn more about the event.
Today’s society is turning more and more to renewable sources of energy, due to an improved awareness about the environmental problems surrounding the other energy sources. Also, we try to utilize and not waste as much energy as possible. Following this line of thought, the Australian city of Cockburn has installed a system of windpods in order to generate power from wind – that is the biggest system in the Southern Hemisphere.
Global warming, a consequence of the Greenhouse Effect, is one of the biggest challenges humanity has ever faced. It may provoke massive changes to our planet, such as the melting of glaciers and the consequent raise of sea levels, which will flood many regions. Scientists thought that carbon dioxide (CO2) was the most dangerous Greenhouse gas, but turns out there is a bigger bully in town.
Man and animal exhibit various signs of being in tune with
the universe, but recently a team of zoologists from University of
Duisburg-Essen in Germany made a new finding, one which provides yet
another example of Franz Mesmer’s theory of animal magnetism: Under stable conditions in the Earth’s magnetic field, dogs will tend to urinate and defecate in line with its magnetic field.
There are plenty of electric cars on the market today, but most of us are still driving the traditional gas-guzzlers. Why? Lack of recharging infastructure and so-called "range-anxiety" are two primary reasons for dismal electric car usage right now, but the future is coming. A new battery for electric cars may solve both problems and usher in a new age of worry-free transportation.
