I have a huge problem with that Wikipedia entry:

I see a few problems with this.

So then you never leave your house, as those cars traveling at high speed are all around you!

I've never heard that, and I really can't see how it would be possible, as the only thing that happens to aluminium is that it oxidises, and aluminium oxide is even less reactive than raw aluminium. "There is no concrete proof" - in other words, it ain't true.

IIRC, wasn't there a story not too long ago about using flat solar cells under an almost-half-cylinder, so the refraction bends the incoming sunlight onto the cells no matter the angle. If you then had the half-cylinder hollow, so the water ran through it and over the top of the cells, the water would then cool the…

If your hot water tank is using pre-warmed water from these, it makes for much less power usage heating it the rest of the way. Freezing would be a concern, though, IMHO.

Or you could set Season 2 of Firefly BEFORE Serenity but AFTER Season 1, so Wash and Book would still be alive. Book may (If Ron Glass is not available, or only available a little) have left the Serenity.

I just threw up in my mouth a little. Thanks for that.

I believe yes, it looks like (If you look at the second video, where there are some brief shots of the "pilot" as the quadrotor flies over) the pilot has a HMD on, probably a set of i-glasses or something similar. As it's a quadrotor, it means the pilot needs a slider/analog trigger for height and a 4-way stick for…

Right. And the HMD he was using wasn't transparent, so he couldn't see through the glasses. Thus, he used a HD webcam (mounted on/above his head, and cropped/framed out of the side-on video) and overlaid his UI on top of that feed, then fed that feed into the opaque glasses. So what you're seeing is what the user is…

From what I could gather, Google's version wasn't using eye tracking, it was using head tracking - You tilted your head back and looked up to see and use the UI, and you turned your whole head to change view. This is quite doable now (Head tracking isn't that complex, I had a VR system that did it based on an ISA card…

Or it could be that the display on the (non-transparent) HMD he was using was provided from a HD webcam mounted above his head. Thus what you're seeing in the video (at least, the 1st-person view) is what the user is seeing.

And Babylon 5 was even worse. They were told they were cancelled, and so wrapped everything up at the end of Season 4. Then as Season 4 drew to a close, they were renewed for Seasons 5 and 6, and had to scramble to do something after everything had been wrapped up. So they came up with the expansion on the psi-core…

You're missing one that my new Samsung plasma happens to have (to my intense joy): Ethernet! Yup, Plasma TV + Ethernet cable + Serviio = complete media center from your NAS.

Nope. VGA can be used for any resolution, all the way up to 4320p, but being analog the timings and signal noise make these higher resolutions blurry and impractical.

Unrelated to the original topic, but related to the image from "3 Idiots", they didn't use pencils because spraying conductive graphite powder in a zero-g environment over sensitive electronics that take care of important things like life support might not be such a good idea. And if you're thinking "Writing with…

There's something that's tweaking that "Uncanny valley" vibe about Rapunzel for me. Probably her left upper arm being too short. Or maybe it's the angle her right arm and wrist is at that looks painful, if not completely impossible.

I've been in an anechoic chamber, and it's very creepy indeed. This one, however, had speakers and microphones built-in, and when they're not doing technical measurements they feed back ambient sound inside the chamber, cancelling out the anechoic nature, but also not driving you insane.

Are you kidding? These things look great. All that functionality, AND you get to look like Garrus? Sign me up!

With a HMD like this, you can use a thin wire leading from it to the actual brains of the unit on a belt pack. Then, as you don't need to pick it up or hold it, it can be larger and heavier than a regular cellphone. If you go with a "slim backpack" form factor instead, you can have even more battery life. Imagine, if…
