Previous A123 cells have all been cylindrical but this new unit follows the packaging path used by other GM hybrid battery packs. The prismatic design should allow a higher density of cells within a given pack volume but may cause issues with thermal management. While A123 has their own monitoring software and electronics available, GM currently plans use in-house developed code to determine the state of charge of the battery pack.

In the Question and Answer session following the Speak Up Europe conference, Italy’s decision to phase out nuclear energy came under attack:

PowerHouse Enterprises has developed a modular home that incorporates green elements into its design, including a solar butterfly roof that collects rainwater. There are also solar panels for electricity and hot water.

metal roof served to heat the house during winter by absorbing heat and generating electricity

EU plans to build an 'energy community' to deal with the challenge of climate change, security of supply and competitiveness are "as full of risks as […] hopes" given the "violent conflicts of interest and prejudices" involved, according to Philippe Herzog,

12 minute interview with Roberto Zangrandi, Head of European Affairs at Enel, during the lead-up to the first “Speak Up Europe” energy debate

Attach 400 pounds of batteries to this mammoth mill, and the resulting ecotank offers no improvement in highway fuel economy and slightly less towing capacity over the old-fashioned dino burner

Like any typical consumer, the participants in SmartPower’s study want to know what is in it for them. They yearn to be inspired. They do not want to be preached to. They want to feel that they are a part of a “we” approach. They want to understand and feel the real world ramifications of their actions. They’re busy. They’re over worked. They want simple, quick tasks they can do which will make a difference. They want to feel smart and cool. They want to feel empowered and knowledgeable about saving money and saving energy. One of the participants responded, “When I save energy it’s like a light bulb has gone off in my head that I’m getting it.”

Development of the first hybrid battery suitable for storing electricity from renewable energy sources such as solar and wind is now a step closer.

If you have only one hamster, the treadmill is either turning or it isn't, so the power's either on or off. With two hamsters, the odds are better that one will be on a treadmill at any given point in time and your chances of running, say, your blender, go up. Get enough hamsters together and the odds are pretty good that at least a few will always be on the treadmill, cranking out the kilowatts.

just using hamsters as an analogy for wind turbines!

Remember the hippie movement of 1967? Those naive, young but well-meaning guys and boys who believed in “making love, not war” at a time when the US was fighting one of its dirtiest wars in Asia? Well, I guess a lot of these guys and boys now are running big businesses (or advising them) and still seem to have the same vision of humanity than in those times.

The scheme would make the use of renewable energy, particularly wind power, so reliable and cheap that it would replace fossil fuels on an unprecedented scale, serving 1.1 billion people in 50 countries.

Czisch didn't comment on superconducting transmission, previous post, for some of the main lines, which are higher efficiency and more importantly can conduct up to 10 times the amount of power of today’s conventional copper cables of the same size.

Can one write something new about the latest synthesis report from the United Nations Intergovernmental Panel on Climate Change? Not really

Not only is it just repeating what was in the three earlier reports this year (although maybe with a bit more political courage), but what it confirms is already known for years (although some still need convincing because they have so much to lose):

o the politicians have finished arguing over the use of "very likely" versus "likely" and the final IPCC report is out

But for me the most exciting thing is that we can do something about it

he first hybrid car is a 100-year-old Porsche! The car had in-wheel electric motors and an onboard gas engine to recharge the batteries.

"This process produces 288 percent more energy in hydrogen than the electrical energy that is added to the process," says Logan.

Water hydrolysis, a standard method for producing hydrogen, is only 50 to 70 percent efficient. Even if the microbial electrolysis cell process is set up to bleed off some of the hydrogen to produce the added energy boost needed to sustain hydrogen production, the process still creates 144 percent more available energy than the electrical energy used to produce it.

7th November 2007 the mainstream 10:30pm ITV news in the UK discusses the "peak oil" documentary Crude Awakening, hears the IEA warning of much higher oil prices, shows how many countries have already peaked

Are we already talking about a new generation of renewable energy sources, or at least a new generation of capturing energy sources?
