So……..
I just thought about it.
If I use like 20 magnifying lenses and arrange them so that all of them catch sun light and magnify it at a small tank holding like a cup of water, will it boil the water???
What I am saying is that, when a magnifying glass calibrates with sunlight, it literally can start fires,so can a few of them start to boil water?
I am thinking about a miniature version of those boiling water soar farms like in Spain. Solar Furnaces.
Would it work?
