2. Hinterland energy in Guyana - Wikipedia

   en.wikipedia.org/wiki/Hinterland_energy_in_Guyana

   Portable solar light kit. In 2009 the Guyana Energy Agency and Office of Prime Minister in collaboration with Ministry of Amerindian Affairs provided 1000 portable solar light kits to 19 Villages in Regions 1,2,7,8 and 9. The kit consists of a 15W panel, a charge control cabinet containing a 20Ah battery and three 11W CFL light bulbs. [4]

3. Iron Pot Lighthouse - Wikipedia

   en.wikipedia.org/wiki/Iron_Pot_Lighthouse

   By the late 20th century, the focus shifted to more cost-effective and sustainable energy solutions. In 1977, the Iron Pot Lighthouse became the first lighthouse in Australia to be converted to solar power. Solar panels were installed to charge a battery bank during the day, which would then power the light at night.

4. Lightship - Wikipedia

   en.wikipedia.org/wiki/Lightship

   In the 1930s, "crewless lightships" were proposed as a way to operate a light vessel for six to twelve months without a crew. [8] The first lightvessel conversion to solar power was made in 1995, and all vessels except the '20 class' have now been converted. The '20 class' is a slightly larger type of vessel that derives its power from diesel ...

5. Diffractive solar sail - Wikipedia

   en.wikipedia.org/wiki/Diffractive_solar_sail

   A diffractive solar sail, or diffractive lightsail, is a type of solar sail which relies on diffraction instead of reflection for its propulsion. [ 1 ] [ 2 ] Current diffractive sail designs use thin metamaterial films, containing micrometer-size gratings based on polarization or subwavelength refractive structures, causing light to spread out ...

6. Electric boat - Wikipedia

   en.wikipedia.org/wiki/Electric_boat

   Solar powered: A boat propelled by direct solar energy is a marine solar vehicle. The available sunlight is almost always converted to electricity by solar cells, temporarily stored in accumulator batteries, and used to drive a propeller through an electric motor. Power levels are usually on the order of a few hundred watts to a few kilowatts.

7. Solar sail - Wikipedia

   en.wikipedia.org/wiki/Solar_sail

   IKAROS, the first space-probe with a solar sail in flight (artist's depiction), featuring a typical square sail configuration of almost 200 m 2. Solar sails (also known as lightsails, light sails, and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large surfaces.
