Simple solar thermal for developing countries

The flat-pack water heater that fights climate change
Many people around the world don't have easy access to hot water. But an engineer in Scotland has designed a simple portable device that heats water using just the power of the Sun.
He believes it could reduce emissions and improve the quality of life for millions of people.
"Portable" meaning easy to transport flat and maybe move around a bit.
Nice

Old school Egyptian roll logs and it can be taken for a walk, or a couple of wooden sled skids. Nice idea especially if they scale up the size. Well impressed.

Strange, I looked at it not long after it was posted and link worked fine.

I was thinking that it was designed to be easily handled (both flat-pack and assembled) and up-scalable by simply puttting several together (as in the video.)
Twice as big is 8 times as heavy...

I did similar experiments on ships in Africa and it was always surprising just how fast the water heated. Any way they get it to work is excellent
modular too which opens it up to vertical stacking to increase pressure. Village power shower!

Surely you only need a higher header tank?
er, and isn't the sum more nearly vertically overhead nearer the equator? Or is the sun's movement round enough to heat your stack from the sides - with the benefit of de-rating it to stop it boiling at midday...

Thinking 2 birds with 1 stone, vol & pressure. I love the idea that this is traceable back to Billy the Kid and his black can shower. On the sun's relation to the vertical stack, surely it can't have much of an impact?
