Johnnius, you are right. This is a superbly simple evaporation trap system,
usable in just about every setting. I hereby add this to the
refrigerator-without-electricity, and the mosquito netting pre-sprayed with repellant, as
examples of the kinds of invention I'd like to get created in an
invention-training workshop tailored specifically to developing-world conditions. These can do
a lot of people tremendous good.
Thank you for bringing this information to our attention. ....win
