@bavarian59 I can build my own packs for around $1.50 per cell and the prices keep falling on the tech. I am also building a powerwall and putting solar on my mom's house. There is no difference from running a house or running a boat. I know I have to look at the power to weight and how much I can float. There was a guy that built a wave powered boat and sailed it from Japan to Hawaii

So if you make a combination of these you can have more power to move than you will need. I like to do things differently than the herd. So thinking outside of the normal is more fun. I have not even touched on my Allowistic islands built out of recycled material that are floating self sustaining islands of abundance. More on that later.
