Simple Solar Education

Back in the early 1980s I made some 15 second PSAs for the Urban Solar Energy Association [USEA] that were actually shown a couple of times late at night on the local TV stations.

In the early 1990s, I made another set of 30 second PSAs for the Boston Area Solar Energy Association, the successor organization to USEA, but none of them were broadcast as local TV stations all had their own approved non-profits to soak up public interest broadcast time requirements by then.  Or so I was told.  At the same time, I was producing the monthly lectures of the Solar Association and putting them on local cable access.

In the last decade or two I’ve put my share of solar video online at Youtube.  You can see them at

So I’ve been dabbling in solar video for a long time.   But not for a long time.  These are relics of what I’ve thought and done with simple solar throughout my life.

The presentation may be amateurish at best but I believe the majority of the information and ideas is accurate although I may have made some mistakes in the details here and there.

May these be of use.

One Square Foot of Sunlight 
come from the early 1990s and were the 30 second PSAs I was trying to get local TV to broadcast.

Simple Solar Principles

Solar Is Civil Defense
Cell Phone Solar
Minimum Solar Light
Homefront Advantage - WWII posters
A South-facing Window Is Already a Solar Collector
Solar Windowbox Air Heater
Insulating Roller Shade
Old Solar:  1980 Barnraised Aolar Air Heater
Old Solar:  1990 Boston Area Solar House Tour

I believe you can provide people with the essential concepts of practical solar energy within a very short period of time and can even present it as a series of short segments like these Youtube videos

Simple Solar parts 1 - 8
is my one attempt at trying to assemble a curriculum that leads from one possibility to another.
At a skill share.  Whatever happened to those?

Providential Experimentation
Worms, worms, worms
expands the concept beyond direct solar energy into secondary sources and regenerative systems leading to full geotherapy.

Simply Questions
is an attempt to visualize that system in terms of basic logistics
