Funny enough when I clicked the first gangnam video link I saw I got a message that I can't see it due to the GEMA not allowing me to see it in Germany. (however it wasn't the original, but some live recording - I think the original is available)
I seem to live in a country that's especially crappy when it comes to copyright issues...
Whic h is kind of sad, as I was about to jump on and try it out. Still there's nothing wrong with calorie restriction, as the monkeys in the study seemed to live healthier than the control group - and obesity is definitely a risk of dying unneccessary early. But it probably won't prolong your life as it does in rats and worms.
What's currently gaining a lot of attention in Germany is the technology to transform electricity into hydrogen or methane.
The advantage: It can be put into the natural gas grid which is already there with lots of storage facilities. It can take up to 5 percent hydrogen (and there are discussions if it could be much more with slight technology changes). Methane can be put into the grid in an unlimited amount.
The disadvantage: It's relatively expensive and inefficient.
Hi, I completely agree with what you wrote and I sometimes think it was the biggest mistake of the free culture movement to accept the cc licensing concept of restrictions.
However, I would go one step further: I'd like to free culture even more and reject any restrictions like (legally required) attribution and share-alike. The reason? I could name a couple, but my main one would be: The freedom to mix. If you have two licenses that anyone would consider free in terms of the four freedoms (e. g. FDL and cc-by-sa, or GPL2 + GPL3), it can still be forbidden to create something new out of two "free" things. I find that very non-free. Thus I mainly release under CC-zero (which is, for those who don't know, a legal text for public domain-alike licensing).
