Yes, i know of them. I also know of many that were never built... because the trash people couldn't talk to the power people... grrrrr.

There was one set to go on-line, but the investors wanted to patent it, but the inventor wouldn't do it, saying it is for the good of humanity. The investors dumped the project.

But really, we should be burning all the plastic rubbish. Trucking the shit back to the plant for recycling wastes more oil than making them anew.
(unless you recycle locally, which is totally possible.)

Thanks for the links. I hope all the cities get their own.
