[Gasification] Junked Hot Water Heater Tanks.

[Mark & Elena Gallmeier]

Dear Jeff,

> My gasifier is constructed from a discarded hot water tank.<

That's great.  I've found junked electric hot water heater tanks a great 
resource.  My second prototype charcoal retort is nearing completion.  It's 
built from a junked 40 gallon hot water heater.  Based on the reported 
service lives I estimate the USA alone is generating well over 2 million 
junked hot water heaters annually.  Dozens per month pass through just one 
local plumbing contractor in my burg.  The nearest to me.  The others also 
always have 6-10 sitting next to the dumpsters.

Tanks are heavier gauge metal than oil drums and take welding nicely.  And 
they're a lot safer to cut open than scrapped propane tanks.  Factory new 
they're pressure tested to 300 psi and rated for 150 psi.

The steel jackets are a great free source of sheet metal, too.

Best Wishes,

Mark
