Prospering in future years will be much easier by having reasonably costing access to energy 24/7. We won’t have it in the near, near future unless we act successfully now as fossil fuels are running out. We’ll have to get it or perish. Get it we will by the effort of those clever researchers I keep mentioning along with the fact that Sol sees to it that it sends more than energy each day to planet earth. At present it seems that storage of electrical energy will be the way to go.
More to come but right now I want to watch baseball
Rare Elements found on planet earth are not renewable resources. We either have them handy or we simply don’t have them. We need them in the future to survive & we are finding them difficult to get. This aspect is aside from all the noise about population size & global warming.
Energy is pouring onto earth abundantly (hurrah) & unfortunately a lot of it at times when we don’t use it (oh dear). The common lead-acid battery is not the answer & much faith is being placed on batteries with vanadium poles. We need energy. We need abundant supplies of rare elements such as vanadium to build useable batteries (that we have yet to invent).
In a much commoner case the non-renewable rare element chromium is used to coat steel (e.g. car bumpers). We are currently gobbling up chromium element & urgently need to find more.
Not easy additions but still workable are our exploring the much neglected sea bed source & the rich source of solar system meteorites. Neither are renewable resources but resources that could supply our needs for some time. Also there are the possibilities of using the ever resourceful scrap dealers more than we have done yet.
Not a very nice post is it. Rare metals resources are a stand alone issue to solve as we deal with all else if we are to be humans on planet earth.
There are though possibilities…..
Our clever researchers may get some from seawater Seawater Source
They may find ways to get some from Asteroids & Meteorites Valuable Asteroid
Don’t rule out some (a little) from scrap merchants!
