Thanks for the clarification.

With autonomous vehicles will come an increased ability for the local, state, and federal governments to track where and how much a given vehicle travels. The governments will then find it convenient to levy taxes and/or fees accordingly with the amount of destructive damage done to the road by the vehicle, which increases exponentially with vehicle weight. So it is unlikely to be as cost effective in the future as it is now to literally drive your whole house everywhere you go.

Of course, we also need some sort of trade tariffs to keep jobs from going overseas to countries with slave-like working conditions.

So I looked over the Microzap website and I couldn't find a good explanation of how this microwave technology kills the mold spores other than the vague description:

"The unique MicroZap technology utilizes a combination of thermal and non-thermal effects to destroy bacteria at lower (colder) temperatures, thus creating “cold pasteurization” of fresh foods and eliminates deadly pathogens."

The thermal mechanism seems obvious, but what might be the "non-thermal effect" they are referring to?

As long as the magnetic field stays at least somewhat parallel to the earth's surface, a lift force will be generated regardless of the field polarity.

Of course, if there is zero magnetic field that means no lift force, but that doesn't mean things immediately fall out of the sky, only the potential to drop a little in orbit until the field picks up again.
