RE: balcony solar (aka plug in solar) interview on Living on Earth

Great interview, covers all the bases. This is another in a long list of "No Brainer" ideas that should be encouraged and accelerated into new construction. We hear of the grid falling behind energy demand--if enough of these 5 or 10% augmentations to household electrical systems were in place, perhaps ...

Thanks David! Yes, it was clear about PV-direct-to-the home electric system, and that's awesome. I've interviewed several groups that have put together kits for kinds of family "nano-grids" with PV to a box with an induction cooker, small battery, and USB ports. Promoting primarily in Africa. Sounds ...

David Power - Utah leads the way :) In the meantime, there are solar thermal cookers that can be secured to any balcony with an equator-facing sun catchment area. My favorite is a design by Milind Kulkarni, from India, an inventor who responded to friends' laments about not being able to solar cook in ...

RE: Should ASES be educating more about efficiency-first building strategies?

Trick question? LOL Answers: Yes, Yes, Yes. The recently posted NAEBRS conference would be a good place for gathering the best education components about efficiency-first solar strategies for buildings. As a maniac for solar thermal cooking, it would be great if ASES members could post their experience, ...

I had 6kw installed on my roof in Minneapolis in 2016, and our bluetooth monitoring showed it would generate just shy of 6.2kw.... 9 years later, it's still cranking out 5.5kw regularly under full sun at solar noon, though it may spike at a bit under 6kw... I think a smidge of that lower output of late ...

One of my latest solar cooking visits was to Sebastopol California to visit Tor Allen's Solar Schoolhouse. As with anything related to solar energy, a top priority is to educate our youngest community members. Tor has put together an inviting textbook and has put many solar cookers to work with solar ...

There are many examples of cookers that can be inserted into a window or an equator facing-wall for those who have sunlight shining on their homes: The Barbara Kerr/Sherry Cole "Through-The-Wall" solar oven is celebrated by many in the solar cooking community, likely it is rare that it is actually ...

I had a pleasant forward-looking interview about solar cooking on Nate Hagen's "Great Simplification" podcast series last week. Nate focuses on energy issues, with a bead on the eventual decline in fossil fuels and the challenges facing the world due to an overdependence on same. I dropped a lot of names ...

Agreed on having a presence in cities, we need more solar cooks to bring the more manageable sized cookers to community events (such as I've displayed at Minneapolis' Open Streets fairs) and green gatherings. Which brings me to the middle of my trio about the Villager, with Mark Shook detailing how he ...

The window is roughly 4' square, as are the larger reflectors. The gaps between the 4 large reflectors are filled by 4 trapezoidal reflectors, 3.5' tall by perhaps 2' at the top and not quite a foot at the bottom. They lean out and grab at least another 2'x4' of sunlight each, to bounce into the cookbox. ...

RE: Solar Oven Sun Tracker Question

I'm aware of at least one dual-axis tracker, i.e., he set up a platform with two gears run by mini-solar-panels (recycled from toys, solar lights etc.), to tilt a cooker to face the sun and turn wheels to follow it through the day. Stan Wells is the designer, I interviewed him in my first solar cooking ...

My rare two cents to this forum re: PV. "If you are frugal and sensible about what you use and when (like using your electric dryer only between 11 and 3 when the sun is out,) you can live on 40KWH. (I live off grid, and I can confirm this is possible)." Frugality is relative :) I have 6kw on my roof, ...
