I have just returned from Palu in Sulawesi where I saw many wonderful sights, one of which was a little wooden shack out at sea.
Around a mile from the mainland, one man lives alone in this shack alongside a small sand dune where he can walk around and admire his view. Or perhaps do a bit of snorkelling if he fancies it!
I didn't see any solar panels so I imagine he has only candles to light his 'home' at night.
His home is actually anchored to the seabed and floats when the tide is high. I can only imagine what it must be like when there is a storm!
What a great way to live.
...if you are into solitude, meditation & seafood :)
