When I first came across this project, I thought it was fairly uninteresting. The landing page features a bold-text heading that says:

Rebuilding My Grandfather's Sawmill. With Bitcoin.Rebuilding My Grandfather's Sawmill. With Bitcoin.

This is the kind of heading that turns me off. And they have a geyser page...and they are raising money (you can "request an allocation") -- all of which are pretty big red flags. So I can't really speak to this specific project, but...

The presentation is scammy, but their concept is really cool!The presentation is scammy, but their concept is really cool!

Lumbermills take a bit of power. Milled lumber also needs to be kiln dried (put in a hot place for a while). Where there's heat and energy, there can be Bitcoin mining!

The concept they law out on their website is this:

1. Log and mill lumber.
2. Mine bitcoin with excess energy.
3. Use heat from miners as kiln heatsource.

The mill is kinda the big power draw and the Bitcoin miners do feel a little like an add on, but I could see a world where a small specialized mill for exotic hardwoods might find the right mix.
