The green movement has misled the world about the dangers of radiation. By George Monbiot. Published in the Guardian 5th April 2011 Over the past fortnight I’ve made a deeply troubling discovery. The anti-nuclear movement to which I once belonged has misled the world about the impacts of radiation on human health.
Hydrogen as a fuel has an excellent energy density per mass, roughly 33.3kWH/kg.
Super-efficient solar-energy technology: ‘Solar steam’ so effective it can make steam from icy cold waterNov. 19, 2012 — Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's Laboratory for Nanophotonics is so effective it can even produce steam from icy cold water.
In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine. Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today's announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.
Still happy on hydrogen
Confined chamber for the plasma.
(PhysOrg.com) -- A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth.
Photovoltaic cells are best known for turning sunlight into electrical power--and they're big business. But did you know that there's a type of PV cell that eats heat instead of light to make power? It could replace the Li-ion battery in your cell phone, and it may also be used to scavenge waste heat from almost anything that normally dumps it into the environment, from your TV's electronics to your car's engine (even an electrical one ).
There have been rumblings for some time about a mysterious little box that could change the energy world forever.
The world can be powered by alternative energy, using today's technology, in 20-40 years, says Stanford researcher Mark Z. Jacobson | Stanford News ReleaseJanuary 26, 2011 A new study – co-authored by Stanford researcher Mark Z. Jacobson and UC-Davis researcher Mark A. Delucchi – analyzing what is needed to convert the world's energy supplies to clean and sustainable sources says that it can be done with today's technology at costs roughly comparable to conventional energy. But converting will be a massive undertaking on the scale of the moon landings.
Understandably anxious to explain persistent controversy over climate change, the media have discovered a new culprit: the public.
One of the unfortunate memes that has made repeated appearances in the climate debate is that money isn't just influencing the public debate about science, but it's also influencing the science itself. The government, the argument goes, is paying scientists specifically to demonstrate that carbon dioxide is the major culprit in recent climate change, and the money available to do so is exploding. Although the argument displays a profound misunderstanding of how science and science funding work, it's just not going away.
