We all know what we thinking, right :) https://www.youtube.com/watch?v=ECLvFLkvY7Y

That was certainly my first thought! Riker pwned again. ;-) Gbisaga (talk) 07:19, 30 July 2018 (UTC)

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! 162.158.63.100 11:03, 25 July 2018 (UTC)

Here’s a real light hack: https://hackaday.com/2016/02/29/fake-window-brings-natural-light-into-basement/ 162.158.62.183 15:21, 25 July 2018 (UTC)

I used to think life hacks were cool. Then I read a few of them and r itealized they were just Hints from Heloise with a cooler, hipper name.172.68.59.30 16:17, 25 July 2018 (UTC)Pat

This Ikea lamp is more sci-fi: https://www.ikea.com/us/en/catalog/products/00311498/ 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? 162.158.74.243 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.

Hey, did you know you can write comments down here?? Life hack! 141.101.98.244 06:26, 27 July 2018 (UTC)

I thought this worth mentioning. Ikea has been brought up quite a few times now. I wonder if it will become a new theme (I know that's not the word I'm looking for, but I just can't think of the right word). 172.68.58.59 16:47, 30 July 2018 (UTC)


it may be worth noting that unlike the name impl9es (or as imagined by the Star Trek TNG episode), it is unlikely that a Dyson Sphere would actually be a spherical shell due to gravitational forces that would be exerted on such a structure. A more apt term would be a Dyson swarm, with millions or trillions of multi-layered orbiting structures that make use of a star's energy. 108.162.219.88 01:42, 19 August 2018 (UTC)
