I appreciate the way this information is organized in this article and the link. It’s an easy read, so it aids me in making my own speculations.

Practical/actual perpetual motion exists – it’s just so ubiquitous nobody notices. Two examples:

Electrons orbiting atomic nuclei

planets orbiting stars – which can produce useful energy from wind, tides etc

Are they truly perpetual? Well, yes, on the scale of billions of years… vastly more perpetual than you or I.

I would also include type 0.

Actually possible now but the person classifying is not aware of it.

Lasers as weapons exist but have not been widely deployed.
The chemical laser used and tested on a modifed jet had megawatts of power and I think they have had various limited successful demos.

New solid state free electron lasers are at 100kw this year. Navy has funded for 5 years to get to megawatts there as well.

Robots are around just not as good as the science fiction versions.
