btw just for comparison a shop vac can move about 1 gallon per minute
of moist sand (about 8 cu ft / hr) . We did an experiment at work to
settle an argument about weather is was possible to move 1800
"gallons" (~ 13 tons / ~240 cu ft) of moist sand with a shop
vac ....estimated time ~30 hours!

How long the shop vac would last is another question.

If your experimental work wasn't so shoddy, we'd all have
the answer to that question by now ;-)
