One of the world’s most iconic and well known monuments – the Eiffel Tower – just got even better: the French authorities have installed two vertical axis wind turbines to power, at least partially, the tower’s electrical requirements.
One of the prime arguments climate change skeptics throw about is how surface temperatures have remained more or less constant for the past 15 years, hence there is no man-made global warming – it’s all a sham, a conspiracy to keep scientists busy with gratuitous grants and fill Al Gore’s pockets. I’ve written previously about models and observations that explain
Building vertical farms is innovative and can have significant advantages, done properly; but building a vertical farm in the middle of a city… that’s just awesome! In downtown Jackson, Wyoming, developers are working on a vertical veggie farm which just might revolutionize urban food growing.
Forget potato clocks – this is the real deal. Plant-e, a start-up company in the Netherlands created promising new technology which harvest electricity from plants. So far this month, more than 300 LED lights were illuminated by the Dutch company, in a promising proof-of-concept. They also demonstrated that they could power up cell phones and Wi-Fis. Generating electricity from thin air
Researchers at Stanford University coated flexible textile fibers with metallic nanowires to form a cohesive network that acts as a fantastic thermal insulator. The flexible material, made of silver nanowires and carbon nanotubes, is knitted together so closely that the space between individual strands is smaller than the wavelength of infrared radiation. As such, the radiation emitted by our bodies bounces between the skin and cloth.
If the leaf really works as the hype would have us believe, than it’s really a fantastic display of ingenuity. However there’s no paper, no data on tests that might tell us how efficient the leaf is at photosynthesis (if such tests even exist) and no solid scientific grounds that would suggest the leaf would actually work as intended. For the moment, it seems like this artificial leaf in question is more conceptual than it is practical.
An inspired entrepreneur, Shigeharu Shimamura, took an old semiconductor factory that was abandoned following the 2011 Japan disaster and turned it into the largest indoor farm in the world. Using state of the art growing technology, his company manages to make some 10,000 heads of lettuce per day out of the 25,000 square feet facility. This makes it 100 times more productive per square foot than traditional agriculture, all with 40% less power, 80% less food waste and 99% less water usage than outdoor fields.
More than 2.5 billion people around the world lack access to clean water, making them vulnerable to diseases. To help address this delicate world problem, the Bill & Melinda Gates Foundation has funded Janicki Bioenergy to build the Omniprocessor – a self-contained system that processes nasty sludge and turns it into electricity, pathogen free ash and pure water. And to demonstrate how safe
An open letter authored by more than 65 biologists calls for conservation groups and efforts to take a step back and rethink their agenda concerning nuclear power, heavily criticized in the past few years following the Fukushima incident. With all its risks and shortcomings, the authors argue, nuclear power is still the most cost-effective “green” solution to toppling fossil fuel and
New York state officials have chosen to ban fracking also known as hydraulic fracturing after a two-year period of review where numerous ‘red flags’ were raised concerning public health. The decision was made recently at a cabinet meeting in Albany. No fracking in New York For the past five years, the state had fracking under moratorium, while 120 towns had
