Oil, gas, and coal provide us with most of the energy needed to power our technologies, heat our homes, and produce the wide range of chemicals and materials that support everyday life. Ultimately the quantities of fossil fuels available to us today will dwindle, and then what?

Photochemical Conversion of Solar Energy
ChemSusChem, 2008AbstractEnergy is the most important issue of the 21st century. About 85 % of our energy comes from fossil fuels, a finite resource unevenly distributed beneath the Earth’s surface. Reserves of fossil fuels are progressively decreasing, and their continued use produces harmful effects such as pollution that threatens human health and greenhouse gases ...

Abstract Solar energy applications are examined from the point of view of their profit-making potential. The study is based on a consideration of the availability and characteristics of solar energy, the sources of profit in conventional energy sources, and the type of industry which could participate in the commercialization of solar energy.

1979. This aircraft was developed by Paul MacCready and his team to cross the English Channel from England to France. The 96-ft-wingspan aircraft weighed just 55 lbs. The use of synthetic, high-strength, lightweight material played a major role in creating this remarkable design. (Photo: Don Monroe. Courtesy Paul MacCready.) Fig. 3.

While I have wandered from the main subject of the sun, to consider the source of stellar energy, the two topics are so intimately related that their solutions are identical. I consider that I have demonstrated the reasonableness of Jeans's theory by the manner in which it seems to fit the observed facts.

POR1 recently described the interesting discovery of a “solar lake” on the shores of the Gulf of Aqaba, Red Sea, 20 km south of Elat. Such a solar lake is characterized by a very sharp increase of salinity, and, consequently, of density with depth, with the result that a layer of high static stability is produced near the bottom.
