Henning- you ever notice that in the Star Trek universe they always seem to reroute power from some other system to a critical one (usually engines, weapons, shields, life support)....do you really think that energy consumption will solve the problems of peace on Earth? If you don't solve the root problem in the human psyche, there will just be something else to fight over.
The root cause problem is an evolutionary one, it is the step that takes us from a hunter gatherer thought process and evolves us into the next product of evolution, we are far from the completion of development and capability. In fact, we have barely started, we are yet embryonic, restricted to the cocoon of our planet unable to spread. The step is to evolve human thought from competitive to cooperative, from conceit to compassion. Without that we limit ourselves in ability by wasting all our resources on war and making money, both human and mineral resource, that we cannot afford to leave the planet. We are too protecting people's right to be greedy and suck every last dime out of the economy with no regards to the consequence on society like it was listed in the Bill of Rights.
It's a close race and has been for over 2000 years now when Christ made clear what needs to be done to progress. We have not yet achieved those goals, nor has there been any significant advance since Constantine usurped Christianity in the name of Imperial control.
All the technical aspects required for us to leave the planet are lining up to make it possible, so that is encouraging, but that is our technological evolution, and for that we have always been exceedingly brilliant.
Our social evolution though is not coming through though. We hit a stumbling point with money, and the funny thing is, they knew the risk back then and wrote rules to protect against the influence when they created money, and the penalty was being stoned to death for violating the rules.
One of mankind's primal drives is to covet, this is a food based survival instinct required early in the evolution of our species when we lived in sparse hunter gatherer tribes. It is not destructive in that setting because it is an extended family and the greedy child is regulated by the family/community.
As population density grows, and tribal culture develops beyond the family level, this trait starts becoming destructive and leads to violence and general discord. This is where we were at socially in the Fertile Crescent era when society got large and disparate enough to require a medium of economic exchange. They understood the burden and risk of discord possible if money were allowed to become its own commodity, to have an intrinsic worth, so they banned all usury.
In the development of the Abrahamic culture from those roots those rules were modified in the Jewish to be 'no usury among us, you can charge Gentiles' and then they relaxed that to "you can't charge us excess fees" and so the banking industry was born, and made Jews Infidels. Moses was the first revolutionary, then came Christ, and Mohammed, all to stop this, but it hasn't stopped.
The thing about allowing usury is it empowers that greedy brat kid who only knows "mine, mine, mine", those are the kids who grow up to be the leaders of the finance and industry. When you allow usury, you create an economic burden to place on a promise. You also promote those who value wealth and excess as your social exemplars, and this breeds covetous behavior and the social norm of excess consumption.
This one factor is what is preventing mankind from evolving, it is the one factor standing between extinction and space. It also happens to be the one factor that will keep Jews and Israel persecuted until the end of humanity; unless they give it up, change the system.
I have a way to do it that will have everyone smiling, no 'redistribution of wealth' required, no "Jews are the devil and we need to exterminate them", no bloody revolutions or collapses. Just a nice smooth transition into a different financial model with plenty for everyone and wide open to growth, economic growth supported by population growth rather than burdened by it.
It just requires some faith.
