First of all, a non-electric redundancy in communication:

Next, largest dangers in my area are wars, and wars happen with a disturbing regularity. In wars, the primary use of this is, as I see it, is doc**entation of potential war crimes. More solid evidence could help later convict war criminals and… Continue

Well, it's 2020, and the world is slowly shifting away from oil. Smart people invested in the nuclear option for baseload power plants. Cars are more and more powered by hydrogen generated from night excesses from the nuclear plants. Solar shows promising potential with some new avenues of research opened lately as a peak source.

The waste heat from the reactors is harnessed in the winter to heat cities. Energy needs are covered with more to spare.

So, what to do? A party.

Ripple is an open source protocol for a decentralized payment network. It is still largly in development. It uses the existing basis in real world social networks to create money out of social capital.



Looked like a good idea last time I looked at it.



One of it's strong sides is that the general bookkeeping is handled automatically by the computer that hosts the system, so the burnout factor for… Continue

It's a very interesting proposition that could cut cost of transportation of food to urban environments, and enable a degree of self-sufficiency to cities. I hope it will be tasty. ;)

Well, for me, it would be ideal if I found a full time scientific job.

Here is an interesting clean energy project for remote or small comunities. Toshiba 4S is a small nuclear reactor that can give 10 MW of electrical power to a small community.



It is currently set to be tested in a small community in Alaska. If successful, it could enable small communities to function off large grids and have a secure source of… Continue

I've found, from the videos of the hero from mission 1, selected these videos detailing a concept for an urban survival kit.



Water purification is considered mostly at the start of the first video. Note, videos are information rich and are quiet long. First two videos are about 3/4 h, third is 50 min.

My choice is a strange one. I choose a gear reviewer from Youtube, who tests gear and shares information to prepare people for dealing with emergency situations and survival situations, as well as personal defense. His advice is solid. He promotes adventure, service to fellow man and guns.



He is called nutnfancy, and he promotes mastery of dangerous things to help people:…

I am amazed what comes out when I'm considering a problem in a strange situation where I don't have the right tools. I look left, I look right, I usualy find something I can use.



In some ways, looking at a problem trough the context of resource constraints eases the problem solving process (if there is a solution to be had with the resources given). It focuses the mind in a particular way. Because of the somewhat random nature of the constraints the solutions can be very… Continue

Well, for disaster situations, I find the simplest solutions noteworthy. I remember a project by a physicist who went around the world trying to convince governments to print instructions on plastic bottles.

The procedure goes: put infected water in a bottle, put out in the sun for 5-6 hours, the water will be safe for drinking after the radiation from the Sun kills all the germs.

I just can't remember the guy's name.
