Concentration of solar radiation using a heliostat and fixed mirror

Google Caja Solenica or Lucy Solenica. Unfortunately not yet available on the market. But the idea/design/price seem interesting. Best regards

The video is somewhat faked.
Anyone who photographs, has dealt with light a bit (that is, simply pays sensitive attention to it), and can control the exposure on a camera or knows how it is controlled, knows that a room is not really as dark for the eye as it appears to the camera, or vice versa.

I wonder what the difference is supposed to be here compared to the daylight lamp. Could it be the reason that there is hardly any difference, that this technology has not caught on?

P.s.

Thanks Nordanney. Please refrain from further posts. There are too many complainers here and you are one of them.

Nordanbey did not complain but expressed his opinion.
This is a forum, and you have to live with counterarguments here. Nothing is sugar-coated here.
Often, builders see themselves as isolated, even though they are not. And the questioner should be pointed out to this so that he does not get lost in foolish and expensive ideas.

: Great!! It seems something is happening! I will get in touch with the lady

Also calculate the depreciation of penthouses caused by this disfigurement. And the discussion with the building insurance and liability for such a structure. Daylight lamps with appropriate automatic control are the effective solution here.

Then, with a request for a recommendation of a daylight lamp that can replace natural sunlight in terms of [Lichtspektrum] and intensity. Thank you!

Not one, but several. For the entire room or beyond, if desired. There are planners for that or you work your way into it yourself
