You can always make clean water with energy.
That's hardly an original idea my dear boy. The universe came up with it first.
That's assuming of course, that the universe can come up with ideas. You may think that's preposterous. Perhaps not as much as it might initially seem.
When we humans go about our daily lives we walk down the street and just walk right by life forms there right beside us. Ants, worms, bacteria. We don't give them a second thought because they are not intelligent enough for us to really take much notice. You are not looking to have a conversation with an ant for obvious reasons.
Suppose the universe is intelligent, and far more intelligent than we can even imagine. It might be so intelligent as to have no desire to communicate such intelligence.
Or if it did have that desire and it did communicate we might not be intelligent enough to understand it or even realize that such communication took place. Or misinterpret this communication as something else.
The ant you walked by has no idea what intelligence we humans are capable of. We are just this giant thing that moved by. You can read Shakespeare to an ant, but it doesn't register as anything meaningful to the ant at all.
At least that's what the ant told me. And I believe ants. I've never seen one run for president.
