Interesting observation. It is generally accepted that work is not original when it has been previously submitted by anybody, to include the author, for academic credit. While I understand that some code has the potential to be identical, it won't be generally. This becomes much more critical the higher one goes up the academic ladder. A student working toward a Ph.D. who plagiarized would almost certainly be dropped from the program. That’s a lot of years down the drain, especially if they are dropped as the result of plagiarizing their dissertation.

I took a similar approach, but used a 15kW Generac system. There are some things you can do that will really add to this approach, and can make the house really more livable if you have to run on the backup system for a while. I thought I might mention one that pays for itself very quickly if you have access to gas. If you don't already have a gas water heater (and maybe even then) toss the electric hot water heater. Put in a flash system that will heat the water on demand. This is my third house with one, and I swear by them. They take a few more seconds to draw hot water when you first turn them on (they're on-demand units), but the energy sticker says I'm saving $300 per year. That paid for the installed unit completely in three years. This puts zero load on the Generac, and provides an endless source of hot water whether on or off the generator. Having teenagers is enough of a reason to make this conversion.
