The evidence about free energy exists. The fact that you don't know the evidences is another problem.

Now, free energy is kept hidden by our rulers, because free people can't be ruled.
Now we're ruled by others because people don't want to rule themselves, because allowing others to be responsible for themselves is easier than being responsible.

As long as people are unconscious, they choose what's easy.
Choosing what's right (e.g. responsibility) implies freedom of choice that is a component of consciousness.

i don't see how energy can be a problem in a world in which people are conscious.

In this world, free energy is not kept hidden, because we don't have rulers, because people can rule themselves.
When free energy is no longer kept hidden, we no longer have energy problems.
Not to mention that our problems are man-made through overconsumption - that is caused by the fact that people run by social conditioning, because they're unconscious.
In a world in which people are conscious, we don't have energy problems - whether we have free energy or no free energy.

What do you think about that?
