Divesting in firms that extract fossil fuels makes powerful
statements but does not reduce responsibility for keeping fossil carbon deep
underground. Corporation profit when we buy fuels and power to
drive, fly, heat our homes, and warm our showers.
Solar power charges electric cars, cools homes and runs lights and appliances. But available solar thermal systems are small and
expensive. We need larger inexpensive high performance solar collectors for heating homes, making
alternative fuels and powering industry. I’ve been working to perfect solar
dishes for over 40 years enabling them to perform well in winter. We need simple,
high performance solar collectors that:
1.
Intensify sunlight 1,000 times to power tiny receivers that deliver heat and
power;
2.
Harvest more than 80% of available sunlight;
3.
Are made with home shop tools without welding or expensive equipment;
4.
Can be installed using hand tools and then operate without expert attention;
5.
Replace in less than six months the energy invested in making it;
6.
Operate for 30 years: all parts easily repaired or replaced;
7.
Utilize only materials that can be readily reused or recycled;
8.
Power both themselves and connected systems so they work after storms;
9.
Provide year-round hot water, air conditioning and space heating; and
10. Pay
for themselves in fewer than ten years, without subsidies.

Working alone, progress is slow. Anyone interested in helping make solar tools that enable life without burning fossil carbon?
