We all know what we thinking, right :)

Dyson spheres are the future but we’ll never see one in our lifetime, right? Maybe we can build small ones around candles and things as practice. Great art display for your local makerspace! 11:03, 25 July 2018 (UTC)

Here’s a real light hack: 15:21, 25 July 2018 (UTC)

I used to think life hacks were cool. Then I read a few of them and realized they were just Hints from Heloise with a cooler, hipper name. 16:17, 25 July 2018 (UTC)Pat

This Ikea lamp is more sci-fi: CityZen (talk) 20:16, 25 July 2018 (UTC)

I'm proud to say I actually have that lamp in my bedroom I'm me(citation needed) (talk) 23:33, 25 July 2018 (UTC)
The comic's text specifically mentions that alien "Dyson lampshades" redirect 100% of their energy. By having a shell with mirror coating inside that can be closed and thus indeed reflecting a significant part of the light, they are much closer to what probably was intended162.158.150.76 19:02, 26 July 2018 (UTC)

What's the comment about infrared studies being inconclusive about? I was under the impression that infrared light was one of the big reasons we knew there weren't any Dyson Spheres nearby. Is the comic referring to a study or something I haven't heard of, or am I overthinking this? 02:33, 26 July 2018 (UTC)

I think she just meant infrared studies to find out if they have them at IKEA. Referencing the fact that that's what you'd use to look for real Dyson spheres. DanielLC (talk) 09:23, 26 July 2018 (UTC)

I figured out indirect (diffused) lighting in 1982, in McCutcheon Hall at Purdue University. The central hall had lots of light, but no observable, central light source. I discovered that the light came from hidden fluorescent tubes, diffused against a plastered ceiling. The light we saw, came from overhead, in every direction. The basic outcome is: the more quanta you have, the less precise your measurement can be. OTOH, fewer quanta cast a sharper shadow.

The frosted bulb diffuses the shadows of the filament. The bulb's reflector can be an offset to the diffusion.
