| This an operational solar power plant in Seville, Spain, where the sun's heat is focused on a solar tower's top and converted to electricity. Watch a BBC clip |  |

| Another technology is to capture the sun's rays in a dish and focus them on one end of a Stirling engine, that operates on temperature differences.
Here's
a clip showing the principle.
A plant will be built in California based on this principle. |

| Nanotechnology is becoming very important in the utilization of solar power, as shown in this clip, where photovoltaic foil is produced. |  |
||
| A solar tower, surrounded by a 'greenhouse', that, heated by the sun, creates an updraft in the central tower, thus generating electricity. This video shows a succesful '80s pilot project in Spain. |  |

| The sun also heats the surface of our oceans, so by pumping up cold water from down below, a temperature difference can be converted into electric power and, as an added bonus, this technology can provide desalinated water.
Ocean thermal energy conversion, OTEC. Succesfully tested in the early 90s in Hawaii and now regaining interest, as this most interesting article shows. |
