2. Daylighting (architecture) - Wikipedia

   en.wikipedia.org/wiki/Daylighting_(architecture)

   Solar street lights are stand-alone power systems, and have the advantage of savings on trenching, landscaping, and maintenance costs, as well as on the electric bills, despite their higher initial cost compared to conventional street lighting. They are designed with sufficiently large batteries to ensure operation for at least a week and even ...

5. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   A heat pump might use 1 J for every 4 J it delivers giving a COP of 4. A system that only uses a 30 W fan to more-evenly distribute 10 kW of solar heat through an entire house would have a COP of 300. Passive solar building design is often a foundational element of a cost-effective zero energy building.

6. Space-based solar power - Wikipedia

   en.wikipedia.org/wiki/Space-based_solar_power

   Solar dynamic uses mirrors to concentrate light on a boiler. The use of solar dynamic could reduce mass per watt. Wireless power transmission was proposed early on as a means to transfer energy from collection to the Earth's surface, using either microwave or laser radiation at a variety of frequencies.
