This is not a perpetual motion device. It is distinctly different from a device which, for instance, uses energy to convert water into hydrogen and
The potential energy in the final product comes from the potential energy that already existed before the oil was made into plastic. There is no free
lunch here. Forming the polymers to make plastics uses energy as does breaking down the polymers. The advantage is that waste plastic would otherwise
be burned or buried in a landfill (wasting all its potential energy). It is a pretty big advantage to be able to reclaim some of the energy which
would otherwise be wasted.
This should obviously only be used on plastics which were not going to be recycled into other plastics anyway (there is a lot of it in landfills etc).
It is unfortunate that the article didn't specify how much energy was required to produce one liter of oil, other than uselessly stating 1kW. This
means nothing without duration. That one liter of oil (using the gasoline component) could produce 300kW in a V8 engine or 200kW in a V6. The V6 would
just produce it for longer.
I would however, be very, very surprised if it took anything near half a liter of oil worth of energy to boil the kilogram of plastic. I distill my
drinking water and it uses next to no electricity for a four liter batch (about 4c to keep it at a boil for several hours). In comparison, one liter
of gasoline will get a fairly large modern V8 car about seven miles or more.
As CO2 caused global warming is a scam, the only big problems with fossil fuels are smog and running out of them. This helps with one of those
problems. It could also help stop petrol prices being artificially increased so dramatically, as people would just convert plastic instead.

The real issue is folks not disposing of their plastic properly.
Most people only do things if it directly benefits them. Widespread implementation of this device would mean the masses view their used plastic as
valuable fuel rather than worthless rubbish.
I cannot see a better incentive to not have plastic end up in a landfill or needlessly burned off.
