I agree with every word you just said.

It started with the 80 MPH car that went for 400 miles generating its own electricity via some tubes, wires, rods and a Tesla coil on his front seat with him. All with material available at the store in the 30s. I have a problem with that. Its fun to think about but I don't think he ever built such a device. That could not be squashed, he would be driving it around. We would have that technology today.

I have always believed that generating an attraction to gravitational or magnetic fields is possible. Especially for space flight. Direct an opposing magnetic field at earth and a positive field at mars. Push away from earth from one side of your ship and pull toward the target with the other.

Yep, sci-fi is now reality. Think of the principle in Dune like folding space and time as physical properties to travel instantly across large distance. Cool stuff.

I try to aggravate one person a day. Today may be your day.
