I agree completely solving the energy problem also solves the war problem.

I am a car fan too, even though I gave my last one away almost a year ago, seeing already what is coming. It was a diesel AWD truck. If it had been electric I might have kept it, but just not used it until we go solar. After that I would ideally love a hydrogen converted Bugatti, the bigger the engine, the better.

I don't see efficiency as very helpful, as what it does is encourage a tighten-belt strategy, when what we need is an invest-heavily-in-solar strategy, it seems to me.

The reason it has to be solar is that this is the energy source used by nature.

If we see the energy arriving from the sun as positive, then it follows that the energy needed to push up a new plant shoot to the point it sprouts leaves is something tiny but negative, since in that time, the energy required to grow the shoot is travelling from the Earth, upwards, towards the sun, whereas the energy of the sun flows downwards, from the sun to Earth.

After the leaves have formed, then all energy through the plant is positive thereafter, from the leaves of the plant to Earth,

So we might see the little bit of negative energy needed to grow the shoot to leaves formation as a kind of investment, made by Earth, to grow the shoot, to receive the energy of the sun through the leaves, after the plant forms leaves.

If we look at our business to date, extracting oil, coal, nuclear fuel, wood, in fact all kinds of use of fuels of Earth, or even usage of Earth stored energy resorvoirs, like wave and even windpower, they are all negative. None of that energy is received from the sun. All of it is investment from Earth capital.

But now we are starting to sprout our human equivalent of leaves, in the form of solar farms, all over the world, and those are starting to contribute to Earth capital.

It isn't much yet, but it is accelerating.

We might notice also that the hydrogen, and even food we produce from it (See "Solein"), comes at no cost, including no cost to the environment, and even no pollution when we consume or burn it, after creation of the collection and processing infrastructure, the energy just keeps flooding in.

Usage of it even undoes some of the damage done previously by use of fossil fuels. A hydrogen converted engine running on solar generated hydrogen actually cleans the air, emitting exhaust fumes which are directly breathable.

Which one would we rather be locked in a sealed room with? And if we didn't soon turn on the engine, we would even be dying of the waste gases from our own breath.

Zooming back out, we might see humanity is like the shoot of a plant, at the point of starting to spring leaves, or a baby who's umbilical has just been cut, or a chicken who needs to peck its way out of an egg.

We won't do this easily by expending energy trying to conserve energy.

The quickest way out, is to go all out on solar investment, it seems to me.
