Featuring the incredible power of nature, this intense clip from Oceans, a French documentary film by Jacques Perrin (released in the US by Disneynature), shows dramatic footage of several kinds of ships (and a lighthouse) handling some seriously rough seas.
Turning light into heat 24 hours a day, Concentrated Solar Power plus molten salt storage technology (CSP+) works like a typical steam turbine/electrical power generator system on the inside, but on the outside, it is a phenomenal scene of massive mirrors and a brightly-lit tower right out of a sci-fi novel! There are a few different concentration systems, and new mirror designs continue to break ground.
Spain currently leads the way on operating stations and projects under construction, but solar thermal power stations are becoming a more popular energy solution in the United States, too, with over two dozen new plants announced! Take a tour:
Russell Beard of Earthrise goes on a tour of Gemasolar, near Seville, Spain - the first Concentrated Solar Thermal Power plus molten salt storage (CSP+) plant to produce energy 24 hours per day. This power tower plant produces 20MW, enough to power 25,000 homes but much bigger CSP+ plants are now being in the Middle East and the US that will produce 100MW and 150MW. Even larger CSP+ plants are possible.
24/7 solar! The kid should see this.
