Wireless power and ""ambient energy"" are incompatible with real physics.

Sure, they're real phenomena that actually do exist, but the physics are such that they're almost entirely useless beyond extremely specific and very limited applications.

These things have been known and studied for decades now, and the best use we have is charging your phone when you set it down on a special pad. Energy harvesting applications are good for sending a single radio packet once a week. It's just fundamental limitations of the universe.

Anyone excited about wireless power or energy harvesting hasn't read any further than "wireless power and energy harvesting". They aren't what you think they are.
