Here’s a guy, Thomas Thwaites, who is attempting to make a toaster, literally from the ground up, starting with primary materials such as iron ore and mica.
For real retrotoasting, though, seems like he also should make the power source from scratch, with a small generator powered by either a waterwheel or a steam engine. The waterwheel approach might be fairly straightforward, but I’d guess it would be pretty hard to make a viable steam engine without using any machine tools.
Which raises, of course, the interesting proposition of making a machine tool without any machine tools to make it with…
Via Isegoria, who sadly says:
As you might imagine, Thwaites is not celebrating trade, technology, and mutually beneficial exchange; he’s condemning it. Sigh.
Hopefully the project will turn out to be a little more nuanced than that–Thwaites does say “The project won’t be a ‘how is it made?’ industrial promo or an anti-industry tirade either”…we’ll see.
