    And how do humans get their energy? From local farms, at the best. No, these people would have done a lot more good for the environment by using a diesel generator and soy oil biodiesel fuel. Yeah, the solar panels are maybe as energy efficient as biodiesel, but as they mention they produce very little energy, in this case only 85 Watts or so.

    25 comments, and everybody besides the valuable mirror people (thx!) is trying to be funny... I cannot refrain from the idea this must have to do with the /. community perception of these people as just being wierd treehuggers, but a) how is this less hackish or nerdish than other fringe hardware hacking, like setting up overclocked boards in fridges or similar stuff which always gets applauded here, and b) this in fact isn't useless, not because it actually solves energy problems, but it rather points to environmental issues someone needs to address...

    Maybe its too bad for their /. appreciation that its called the Big Green Gathering and not HAL or Chaos Communication Camp.. Nonetheless they have done a nice and valuable hack, and a green one too...

      What's the proportion of energy used to *make* all the comms gear they have vs. the energy it actually takes to power it? 100:1?

      In other words, what's the total energy cost of the product (production, distribution, use) and what percentage are you actually saving? Is it the equivilent of not running the A/C in your 400-cubic-inch-V8-powered SUV because it gives you a tiny payback in gas mileage?

    Generators are banned by the powers that be at the "Green Gathering" whatever they are running on, this may not be correct, but this is how it is.

    So a biodiesel powered generator that burns soy oil and creates carbon dioxide is banned, but a human powered generator that burns soybeans and creates carbon dioxide as well, but does so at a lower efficiency isn't.

    Just goes to show the short-sightedness of these Greens.
