From Guest Blogger Paula: Liquid Air Energy Storage System
Today liquefaction of air offers us a great solution to one of the biggest issues that world energy science faces – electricity storage. According to the Institution of Mechanical Engineers this type of energy storage is just as effective as the traditional batteries and the hydrogen. It can be used to store excess energy, generated from renewable sources like wind turbines. This energy can be frozen to cryogenic air in some isolated place. When it is necessary, this air can be warmed up and it will return to its previous state, in order to be used. (more…)
I’ve mentioned a few times that even Shell Oil believes the market for oil (gasoline and diesel – liquid hydrocarbons) is going away, and will be very small by the year 2060 – almost entirely replaced by electric vehicles – both battery and fuel cell. Here’s an article that analyzes this

Well my nickel-iron batteries have finally arrived from China on Friday afternoon. I have unpacked them and set them up and attached them to my system for their first charging. They are bigger than I imagined they would be — taller actually than I thought.
Everyone on Earth who knows anything about our environment challenges would like to see the elimination of coal-fired power plants at the maximum feasible rate. Yet few (myself included) have a rock-solid understanding of the

There is a large and growing trend in which seniors living in the colder parts of the United States go into assisted living in the fall – only to come out and move back into their homes in the spring. This, of course, is due to the rising cost of energy: people living on modest fixed income sources simply cannot afford to heat their homes. 
It’s the birthday of Geoffrey Chaucer, who gave us the rip-roaring stories comprising the Canterbury Tales. Though I read them all senior year in high school in a marvelous English course called “Chaucer and Cummings,” (taught by my favorite teacher of all time, 
A gentleman from New Zealand contacted me recently about a terrific idea in the integration of solar thermal water heating in residential, commercial, and industrial buildings . I’m off to Los Angeles for a meeting with him in which we’ll discuss a number of different possibilities by which I can help drive sales in the Americas.
If I had another couple of good reasons to be in London, I’d love to check out this
