William said: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!)
Tim said:The principle probably makes sense, but I think it is a bit
oversimplifying and optimistic to describe the output as "inert". For
example the granules will contain whatever heavy metals were in the
original waste, eg cadmium, which will eventually leach into water
courses if they are used for landfill or construction. As they are
produced in a reducing atmosphere, the metal residues will likely be
rather more reactive than in oxidised basic slag.
While high temperature processing simplifies most organics etc to
manageable gases, some hazardous gaseous residues such as dioxins will
remain in the syngas and so in its eventual combustion products released
to the atmosphere. Not all the gaseous product will have passed through
the plasma, some will distil earlier and bypass it, so an amount of more
complex and even biological compounds will remain in the gases too.

Jim said:Here's a cheap one if you want to play;
$2000 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.

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

William said:i got one similar to the "cutmaster 39", they must've discontinued the model
i got.

(i got mine with the understanding that it'd cut 1/4", it is my belief the
one i got the 1/4" rating is exaggerated, i shoulda got the next larger
rated.)
Winston said:Thanks, Bill.
I take it that their 5/8" claim is specious as well then...

William said:hey,
i don't want to appear to be saying thermal dynamics machines aren't as
good as the manufacturer claims them to be, there is the possibility that i
never really learned how to use the machine properly. what do they say?
that the "cutmaster 39" can "sever" 5/8" material? i never tried, maybe it
can. it just seemed to me my plasma cutter doesn't cut as well as i had
hoped it would, i was pretty disappointed, maybe it's just teh way i use it
though. (i just reviewed their info) yeah, if it was me i'd get the next
size larger machine, at least, if not two sizes larger, for me at the time i
bought my machine that was WAY more than i wanted to spend.

harry said:More bollocks. Energy cannot be created or destroyed. First law of
thermodynamics. The total energy out equals what goes in. IE energy
to power the plasma plus the energy in the rubbish to start with. You
don't get anything for nothing. You could get the same effect by just
burning the rubbish.
Just put it in the same file as "gasoline for water" technology.
There's so many uneducated shitheads on this thread it's
unbelievable!
harry said:The technology is pointless. There already exist several
technologies that achieve the same result. Low technologies. That
work. Incineration, biological "digesters" & distillation springs to
mind. Why bring in plasma?
The first law of practicality is "Keep It Stupid Simple". The
complications come along on their own. You don't need to build them in
to start with.
The practical difficulties of building such a device would be near
insuperable.
The nearest I've seen to it would be an electric arc furnace as used
for meltng steel. And they are batch processors,
