OT: Plastic into oil

"One kilogram of plastic waste produces almost a liter of oil while using about 1 kilowatt of electricity."

but i dont know if that includes breaking the plastic down. damn it was the 1st i heard of it. thought this guy was onto something new. bummer.

one kilowatt for how long? 1 minute? two years? one kilowatt means one thousand joules per second. that's the amount of energy used per second, but it's not telling you how many seconds.

to find out how efficient it is you need to know how much energy (in joules or calories) needs to be put in to 1kg of plastic waste, and how much energy you would be able to get out of the product (the oil)...

to make it worthwhile the machinery would really need to be wind, wave or solar powered. pointless using one non-renewable resource to convert another one back to something resembling its original state, when it should never have been used in the first place.

much better idea: stop using so much plastic. use and re-use glass. remember glass milk bottles? wash and re-use.simple idea, far less waste.
