Zenith Solar is certainly more advanced. Thanks for pointing it out.

The difference between the two projects though is open source vs proprietary. Zenith looks very impressive but Solar Fire is meant to put solar power cheaply and easily into anyone's hands. They are both worth following IMO

-----


Yes I agree, I really like the way Solar Fire's mirrors can be bent.

Have any idea how much a ZenithSolar unit costs? Apparently they've given an Israeli community of 1100 people a surplus of electricity with only 16 units.

-----


Their website says nothing, but they link (http://green-energy-reviews.com/zenith-turns-an-israeli-kibb...) to a video that shows a presentation with a slide of their technology with the text:

5 kWh PV + Thermal -- 30,000 Euros

... and they claim their products will last 20 years.

-----


There will certainly be maintenance costs during that 20 years though.

I do like the idea that as PV efficiencies improve you only have to swap out one cell per dish

No, I don't know, but could investigate. It'd be interesting to see a device that was placed in a location over the course of a year and measured different facets of sun and wind for that location and enabled simulation of various technologies.

Each ZenithSolar Z20 unit generates 5 KWh Electricity plus an additional 11 KWh hot water (up to 100 degrees C). 18 units at Kibbutz Yavne are now providing all the hot water needs for 400 people, the electricity is all be sold into the electric grid. ZenithSolar is now installing new fields in Australia and China...paul.linden@zenithsolar.com

They have a TED Talk which is exciting to watch as well

I was fortunate enough to meet Marcin a number of years ago at a conference in Vienna. He was even then working on developing his Open Source Ecology ideas & hardware.

-----


Yeah, I watched it later the night. Kept me up way to long. I'm still very excited about this!

-----


Doesn't work for Chromium 10 on Linux unfortunately

-----


I'll look into this, maybe I can fix it.

-----


Does it apply to amazon.ca?

edit: just read the FAQ. Hope to see support soon.

-----


There is no way to close the "Currently available cities". You should add an X or allow it to disappear when the user presses Esc or clicks outside

Really great site though!

-----


Yeah.. we need to fix that part up. We'll make it a lot better esp. when we have more cities. Thanks for the feedback though!
