We must go for cleaner energy solutions that make economic sense

David W. Titley’s “Climate Change Threatens National Security” (July 6 Forum) is especially convincing because he has a Ph.D. in meteorology and because he was “something of a skeptic about climate change” and because he is a retired rear admiral. He is also a realist when he advocates “cleaner sources of energy in ways that make economic sense.” 

Unfortunately, today’s cleaner sources of energy do not make economic sense. Windmills and solar panels, for example, are uneconomical when the cost of storing electricity is included, which is necessary to stop climate change.

Only concentrated solar power can store heat economically and produce electricity 24/​7. But today’s CSP has been uneconomical because the cost of concentrating sunlight has been too high. There are untried CSP solutions in the patent office that appear to be economical (U.S. patents 7,380,549 and 5,787,878 — which I hold — and 4,365,618). Where are the venture capitalists when you need them?
