1) Logically combining these with a normal solar panel could work well depending on mechanics. 2) Possibly use recirculated hot water (maybe combined with in the house usage to act as a second water tank for hot water) to improve the temperature difference. Probably only in hot climates.

I'm pretty sure you're misapplying this. Either that or misunderstanding things. First, you have to realize that research on quantum theory is currently ongoing. Thus, it's likely that what you know of it will be changing. With that said, I think the best way to approach this is to see what is proven by what stuff is made due to that knowledge. For example: Solid state hard drives are a product of quantum tunneling. They're basically RAM with a spot third spot that requires quantum tunneling to modify. This is so the information can be stored even when the device is powered down.

Maybe if this were to carry to radiation.

I find people getting scared about a robot uprising silly at this point. The mind is incredibly complex. The closest that can be done to reproducing it is limited in a lot of ways. I'm a lot more worried about a bug popping up in something like an airplane causing a crash then AI overlords. https://what-if.xkcd.com/5/ illustrates how silly the idea is. It's a lot more unlikely because a lot of the devices shown aren't connected to the internet. In the end my biggest worry would be society having problems because of how reliant we are on computers. Even then it would be fairly challenging completely compromise the whole internet just because of how much of a patchwork the internet is set up. Different hardware setups with different software versions. The simplest way of course is through tricking people but that wouldn't do it for everyone. Basically it would be possible but fairly challenging because of everything involved.

Won't work in outer space. Good start though.

It all really depends on the sensors you get. A cheap toy like that would hardly have anything going for it. For a full head sensor, there's a lot more potential. If it's able to accurately match patterns in the brain with certain thoughts and clear out the noise then it could work. It would require fairly expensive sensors and some good algorithms tracking brain activity. Not true mind reading, but in some ways, this is fairly close in that regard. I wouldn't be surprised if it requires some training as well.

I suppose that if you get down to it, everything that you can load from the internet is downloaded. However, when referring to something downloaded, it's usually a file of some sort that's referred to. I double checked and saw that yes, torrent files are hosted and thus can be downloaded. My main point is that magnetic links aren't really files. They're just links can be used to reconstruct a torrent file. So in effect, when you load a webpage with a magnetic link on it, you've already downloaded it. tldr; magnetic links don't really count as a download. Your point on the torrent is true however.

I think that's exactly the problem that they're having. They're erasing a signal from history instead of just cloaking it.

Maybe by the time that we've lived in space for a while, we might also learn how to not trash everything. Considering that space isn't very forgiving. Learning how to work with what you have becomes increasingly important especially during the times when we wouldn't have a planet to work with.

Hmm, tell that to my upgraded Macbook. I have 16gb of ram in mine. On the other hand, you're probably right that it will take a long time for the upgrades to show up in apple's store.

I'm not talking about electricity exactly. After all, it's not like electricity is a natural resource that we can just mine beyond the natural lightning storm. The electricity has to come from somewhere.

It's better than spewing it into the atmosphere like what coal does. Also, a relavant xkcd: http://xkcd.com/radiation/

While technically that's true in the sense of the demand for the power to propel vehicles being shifted from a liquid source to a pure electrical equivalent. I suppose that if you think of it, depending on how efficient a car engine vs the electric generators and the transporting and storing electricity, electric cars may or may not add to the problem.

There is one if you really cared to look through the second link provided. There's a nice HD video demonstrating the technique.

While 2 years is pretty ridiculous, I haven't yet heard of a proper 3D printer that can create parts at the quality that they'd need. 3D printing isn't the best for some of the more vital science apparatuses on the bleeding edge of science.
