[…] that it probably created), but the idea is part of what’s behind concentrated solar power and home heliostats. A Facebook friend actually shared the video with me this week in response to my home heliostats […]

seems like a Fresnel lens could do the same thing? And there have been passive tilting devices for many years that allow solar panels to track the sun.

This could seriously improve solar collector efficiency and positioning possibilities since with appropriate heliostat positioning one could use the collectors for much longer periods within the day.

In this case the heliostat would focus on the solar collector.

I have been wandering about this so many times.

Sun is so powerful and sunshine only needs to get inside your house in the heating season (if you have sufficiently large windows)

With sufficiently low-cost heliostats ($399 sounds way too expensive, but $100 would be acceptable) one could seriously reduce heating costs of a properly designed house (big windows again)
