This is the reason we don't have free energy right now.

We will not have it until we, as the human race, would never weaponize it.

The cancerous cell is a good example. What is necessary is for all the cells to be in harmony with their energy usage. Temperature in/out.

Humans are not killing the planet earth. It is true that we are not being good caretakers, but that is changing. We can support a lot more life on this planet.
Things like no-till farming and managed pasture livestock are a huge boon to the ecosystem.

There are a group of people trying to actively rape the planet. And we, as a race, tend to elect those people into positions of power. We will soon stop doing that, as we see just how evil they are.
