Re-asked--
There are wide variety of rocket stove designs shown on various YouTube
movies.
Primarily variations on stacked hollow blocks or 6 gallon buckets with a
removable PCV elbow.
both types have the distinct advantage of being simple inexpensive and quick
to make.
However does anyone have any actual longevity information?
For instance Quickrete in the 60 pound bag is a nice mix of cement, hard
sand and nice small pebbles which with should make a nice
dense concrete. As configured the sample stove has about a base 2 inches
thick, and 4 inch walls. Could this be expected to last a few weeks,
a few months or even a year or more. The bag of cement here cost a little
over 7.00 with tax. With propane costing a 1.00 plus even 2.00
Return on investment is a week, however making a new stove weekly just does
not cut it. Some might it consider if the stove lasted 6 months.
If it can be a year or so it could be feasible especially if it they were
already made and available.
This issue of longevity could be important. I will be able to answer this
myself in the future as I all ready made two. But if some one can answer in
advance it would be appreciated.
