The first solar video I produced was for the Urban Solar Energy Association [USEA] back in the early 1980s. One of the 10 second public service announcements was “A south-facing window is already a solar collector. Learn how to use it.” with the contact information for USEA. Another was “A south-facing porch can become a solar greenhouse. Learn how to build one.” We got a few hundred dollars in a grant from a group that was refusing to pay war taxes to make 3 inch tape copies and I took them around to the TV stations. Even saw the spot, once, late at night, I think on Channel Five.
The next round of solar videos was a set of 30 second spots I did with a graphic designer, Ed Hill, for the successor organization, Boston Area Sustainable Energy Association in the 1990s when I was doing a lot of public access TV, including videotaping and cablecasting the monthly talks that BASEA hosted. There is still a lot of information to be mined from that archive but it is just gathering dust in a storage area in my house in the form of VHS and 3/4 inch tape.
My favorite of that second series was the one on solar history which showed photographs of local solar buildings since the 1940s and back a few thousand years to the solar techniques of Greek houses (https://www.youtube.com/watch?v=BIGS5LSjlnk).
Unfortunately, when I took these solar PSAs to the local TV stations they had no time available. Only one local UHF station (remember UHF?), Channel 56, took a copy but I’m not sure that it ever made air.
Since then I’ve made some of my own short Youtube videos on simple solar principles as I have always believed that you can teach the basics of practical solar energy, at least for emergency/survival electricity and heat, in a half hour or less.
Recently, I compiled a playlist on Youtube of all my simple solar stuff at https://www.youtube.com/watch?v=6_NN__fS5pM&list=PLkauPyDTdD2A9t4w-ZVMytJS8MpE2dB7N
Some of the products mentioned are no longer available but I believe the basic solar information is still good.
