Join Windy Schor and Solar Sierra for the grand opening of the Sustainable Energy Science Lab, an endeavor of EnergyTeachers.org to study and to demonstrate renewable energy and energy efficiency using dynamic objects and other Second Life (a virtual reality) tools. Come ride an elevator to the top ...

I checked out Omar's suggestion. The site does aggregate news about hydrogen and fuel cells, including a gem about a DOE grant for energy ed in South Carolina. Turns out the US DOE is giving these SC hydrogen stakeholders money to lobby for hydrogen in the state legislature, though the headline make...

Read this forum for some numbers and interesting interpretations from computer users on the power (and VA) usage of their desktops and laptops:

True, James, that the little generators you put on the frame to run your lights are 1-5W; but, with this 10 kg generator, students have been able to output 75W into three lights or 100W into a battery.

Solar Sierra will be giving two tours of demostration-sites using solar technologies, mostly photovoltaic, but also solar hot water and solar cooking, in Second Life. Saturday, June 7, 7:30AM SLT (Pacific Standard Time). Wednesday, June 18, 11:30AM SLT (PST). Both tours will leave from Etopia Prime ...

Second Life is an online, virtual reality with tens of thousands of users online at any time, from around the world. I've created an "avatar" there, named Solar Sierra, who discusses solar technologies and sells virtual solar cookers. You can learn more about Second Life at their web site:...

Our own Windy Schor, a Second Life avatar, met Szavanna Anatra, another avatar, and the discussion led to solar cooking. Szavanna gave us a link to her blog, including items on solar cooking:

Check out the blog, see entries on solar cooking.

Later in the same day I posted the first post in this topic, yesterday, I sold two solar cookers for about US 4 cents each. I wonder how much people would be willing to pay for a such simple solar cooker kit in real life. You can start to answer this question at Solar Cookers International: http://s...

For the past two weeks, I have been exploring Second Life (SL), an online world full of tens of thousands of people, some just visiting, some spending most their waking hours there. http://secondlife.com I recently set up a booth there with EnergyTeachers.org labels, selling a box-type solar cooker,...

Appropedia is an excellent site for technological innovations, mostly on the scale of an individual's work: http://www.appropedia.org/ One example is the Solar Charged Lawnmower, a car-battery powered lawnmower. http://www.appropedia.org/Solar_Charged_Lawnmower It seems like such a good idea, since ...

I'd like to start a forum discussing interesting projects in that teach about renewable energy as a technological centerpiece. Please reply if you know about any good projects.

You can take a nice mouse-click tour of New Hampshire homes at

Charges do not necessarily take the physically shortest path, but are forced to move away from other like charges. Imagine anthropomorphized electrons, as they are forced in 120th of a second to get from your left foot to your right: Electron 1: I'm going to go through the groin. Electron 2: Well, I...

It's AC, so it charges and discharges you at 60Hz. You're toast. Why would the charge not go wherever it can? There isn't much more resistance to go through your shoulders to get to your left foot from your right, than there is to go through your groin.
