    Solar in Las Vegas 

    I was in Las Vegas for a while and decided to upload some pictures of my home renovation solar experiments. This is a 500 feet black hose that is connected to an old water heater. The hot water should circulate using D5 Solar circulation pump. My goal eventually is to concentrate solar energy with computer controlled mirrors or by pointing an old C-Band satellite towards the sun.

    It would be cool if one can find funding for organizing green development camps. For example a group of enthusiasts can get together once a year and dedicate 7 days to get their ideas into a working prototype. A demo session at the end should show the final  result. The funding is necessary for materials, travel and accommodation. Videos and pictures can be published so that the joy is shared :)

      I think that it will be more efficient if the sun reaches the water directly, through a glass or transparent pipes. Rubber is not very good temperature conductor, it is actually very good isolator. Hristo (from Kozarevec), who has some experience, is using combination of sun heated water with gas burner or just regular wood-fire heater.

        It would be cool if Hristo can share his prototypes on the blog… Unfortunately we are blocked by the language barrier and until we get this blog to be multilingual. Its quite challenging to get oneself to write in its own language already… About the solar prototypes, i think CSP http://en.wikipedia.org/wiki/Concentrating_solar_power looks very promising.

      I like the idea about the camps!
      It will be really cool. Somewhere in the mountins or even in Hroisto’s backyard, about noon everyone is already drunk and generates hundreds of new ideas. :D

      PS: Don’t bring any females though, they will spoil it all.
      PPS: So, may be in the cold mountins is better idea, women don’t like to go there anyways, so no need to convince them. ;)

        I’m glad you like the camps… I think Bertrand is also exited about it. We may even be able to raise funds for it, assuming there are projects themes, goals and people willing to share their thoughts ahead of time in order to do some preparations. Lets go for it.

    Easy Low Cost No Radiation Fusion 

    Guys, this is huge.

    Easy Low Cost No Radiation Fusion

    Somewhere else, I’ve also read the US Navy approved $10B research spending for next 5 years on this project (don’t ask me why exactly US Navy)

    I want to bring back to our attention (after more than 20 years!) Carl Sagan and his TV Series Cosmos, which has inspired tons of discussions and brainstorming between me and Yonel back then. The great news is that all 13 episodes are available on Hulu and I don’t know about you, but I’m gonna watch them again!

      That’s great. I grew up with this stuff. Actually, several months ago I was looking for these movies and searched through some torrents but was not able to find the entire collection at good quality.
      It looks like they are on Hulu with (cc) license, interesting.

      …opss: For now, Hulu is a U.S. service only.

      According to EzTV.it, the series are being ripped and distributed in higher quality than old releases as they get released on Hulu.
