Hi @samstonehill. Sorry to hear about the refuge problem but great to see your positive response.
I've long been a supporter of solar lights (through Waka-Waka - https://waka-waka.com) for developing countries and refugee situations and my son is running a Rotary programme sending solar lights to New Guinea. I'll let him know about your situation.
Like @allowistcartist, I've been interested in cheap, simple solutions for clean water and cooking as well as light. I've written about some on my blog. For example, https://www.greenbizcafe.com/?p=3478 and https://www.greenbizcafe.com/?p=6100
Will resteem and follow.
