cool.  never heard of it before, i don't know anything about it, other than
that i own a small plasma cutter.  i kinda reeled back when i read in this
article than they're planning on "mining" an existing landfill and burning
up all the garbage in it.  wow.  i never woulda thought they'd be able to
generate energy from burning garbage with a plasma torch, i woulda thought
it would've just USED energy.  wow.

(<joking> i guess that would be a solution for me when new york state DEC
bans all outdoor burning, if i can get a home version of those babies!)

That's the beauty part. The garbage gets converted into a few inert granules,
steam process heat and two kinds of flammable gas *without* burning.


Getting 21.4 x the input energy out of the process in the form of
steam and syngas is a fine bonus!


Using his numbers, seven cents worth of electricity and a cubic foot of
garbage turns into $.50 worth of energy output and a third of a cubic
inch of inert gravel.

This means I could put a 200 years worth of garbage in one 32 gallon can
while collecting over $8K in process heat and syngas from it.

Not too darned shabby.

How much did that plasma cutter cost, if you don't mind my asking?

Here's a cheap one if you want to play;

$000 and UP is more typical for industrial quality. Mine converts
240V, 30A and ~1HP of compressed air into a needle-thin plasma jet
that will cut 1/8" steel like scissors.

Like these scissors;

In effect all that electrical power equals 1 me-power with the hand
tool.
