sciencekommittee/tech collective -- DO SCIENCE!

Forums:

i refrained from making a group on facebook for a list of reasons longer than my arm -- a list which grew even longer with the recent ipo -- but i am sitting on, still, a small collection of incomplete laptop and desktop computers and also looking to hold workshops on computing and on building solar ovens for dirt cheap. i've also got some halfcooked projects i haven't gotten around to finishing (living in a collective house where everyone had different ideas of what we'd do with the space makes it kind of hard to stick to a plan) -- solar-heated stirling engines from old soup cans, diy hydroponics.

anyone who's down to take part, do let me know. and if you've got more ideas, let's get together and imagine shit. at the moment, physical meetings might be difficult for some of us, however this forum is a perfect place to link information and share thoughts until we have a more permanent physical space.

I'm 100% down for this, I would like to get started/help finish some of these projects you are working on. Now that education committee is back in full force we can certainly do some workshops and help people build their own cardboard solar ovens, pumps, etc.

Has anyone tried this site out? Seems pretty legit.

I've posted this before. I've built cardboard solar ovens since the early 90's. It works GREAT for some things...others..not so much.

Like I posted in FB. I've searched all over for an inexpensive way to "do" solar. Although I have looked at many sites. I can't find a cheap way to do it. The storage problem alone...UGH!

HELP! LOL

there's a link in the

there's a link in the previous post, tammy! diodes are light-sensitive and convert light to electricity. there are a number of other ways to generate electricity from sunlight as well, such as using heat to drive water through a turbine, or focusing heat onto a stirling engine through a fresnel lens or a reflective dish. there are also designs floating around for solar refrigerators, water heater heaters and other such devices.

UGH

I have to look to my settings in here...I never got an email that you had replied. The "Problem" cost wise I'm seeing for panels is the storage of electricity generated. (I'd like to be off grid) It's very expensive to get all the deep cell batteries to store enough to run one place. I'm looking more for cool storage for food. As far as lighting...there are other ways to deal with that...nothing else..you get up when it's light and sleep when it's not! HA! I've looked at the solar refrigerators...but the capacity is not good right now...LG units...small storage. Have you seen different?
