If you believe you can make power tools with some dirt and a 3D printer, many would have a bridge to sell you.
You will not find any fossil fuel on Mars or the Moon no matter how hard you look. Mars has very little atmosphere or indeed Sun energy input. It is difficult to think of a less hospitable world than the Moon. At this stage seeding either with people is not a sustainable solution and would not help Earth. So what use is it exactly?
No, resources on Earth and even the entire solar system including the Sun definitely are finite. We are not even talking about a very long time in the future. According to your theory at some point coal could become more expensive than diamond. But you cannot run a civilization on diamond.
Most economists would say that Western capitalism requires a growth rate of about 3% per year to keep everyone happy (low unemployment, funding, etc). At a sustained growth rate of 3% per year, we would be using the entire energy output of the Sun in 1000 years. Do the math. Civilization is a lot older than 1000 years. From this, two conclusions
1- Even the entire energy output of the Sun is a finite resource
2- Western capitalism will fail even in the not so distant future.
For those who would say "but we can make a lot of progress in 1000 years", I would like to point out that contrary to popular opinion, we haven't made that much progress since the 11th century.
Plus 5 degrees of global warming everywhere due to all these coal-operated power plants to conduct the artificial and useless computation called mining.
Fantastic video. Thanks.
Sadly, your personal sacrifice is of very little import. Mennonites and Amish are pretty much self-reliant, so their impact is not as great as you think.
Please do the actual math. The energy required to move a sizable portion (say 10%) of mankind off this planet is tremendous. Just off, not going anywhere. It is currently not economically feasible and physically very hard.
Also notice that when energy is spent, it stays spent most of the time. At 3% annual growth, which is the amount politicians like to think is a minimum to guarantee such things as employment rates, it will take about 1000 years to utilize the entire energy output of the Sun.
Total power used by mankind today: 10^13 W
Total solar power striking the Earth: 10^17 W
Total solar power output: 10^26 W
3% compounded over 1000 years: 10^13
Who knows where humankind will be in 1000 years but my guess is that we are unlikely to achieve a Dyson sphere.
The advantages are several, here are a few I can think of (not that I practice them myself !)
1- You can use your Windows installation in both a real and a virtual machine. Some VM engines allow you to run off a physical disk, like VMWare. If you dual-boot from Linux or OSX, sometime you want to use your windows installation to check out some software and you do not want to reboot and lose your current work. With the DRM version of Windows, you would need two licenses, even though you are never using both at the same time.
2- You can change your hardware anyway you want. The DRM version will unregister itself if you change the CPU, the motherboard, too many disks, the graphics card, and whatnot. You have to re-register by telephone, which is a huge hassle and may stop working if you do it too often.
3- You can carry over your installation of Windows to your new computer (same issue as #2, really).
4- Why do you need as many licenses of Windows if you have say 3 computers but only ever use one at any given time ? Say one at work, one at your SO, and one at home, if you are self-employed?
Basically Windows is behind the time. Linux is free and good, and OSX is becoming more and more gratis (not libre, unfortunately).
Ornamental subjects like dentistry? Please read the article before making such comments. Cheers.
Very well played, sir.
Us old guys have been on the Internet wayyy before 1994, more like 1984. Lots of value *even then*. For instance in 1991 I would have had no means of communicating with my wife-to-be without the Internet.
There is not much difference with respect to physical properties between printed and sintered metal or ceramics. Sintering is a very well established fabrication process combining endurance, flexibility in design and low weight. However, laser-powered, layered construction a.k.a printing allows for even greater flexibility and most importantly one-off fabrication. This is ideally suited to medical applications like this one. However do not expect to be able to do this at home anytime soon.
