I love to see a good job of re using one item into another. Making a shipping container home is close to the top of my list, and these people have done an exceptional job. I learned some new information on insulation, and picked up a great idea about inside drying of clothes. I would have used more space of sleeping areas, but these are functional.
Their solar system is a little heavy on panels Vs batteries, but shallow cycle is good for batteries of this type. They have a 25,000 watt battery bank; and a 6000 watt solar panel bank! This means that the panels can fully charge the batteries in about 4 hours. They are further north than I am, but sunlight here is a 10 hour average, so they have overspent on panels. Half (3000 watts) would have worked as well. Splitting the charge up with a wind generator would have been a wiser combination.
That said, I really like this house, and it is worth the time to watch! :)
