i was told you are the go to guy for this question.
i would like to do some volunteer work in ben tre province or my tho city on my next visit.
specifically, i am looking for plans, written in vietnamese, for a solar distillation unit. nothing large, just able to provide about 10 or 20 liters a day so that our neighbors and family can have better drinking water.
other than that, i am a carpenter, my wife lives in ben tre, and i have a little free time on my hands when i visit.
any ideas?
