I actually use thorn inner tubes off and on. I can't tell a huge difference for preventing flats or for weight.
And I see someone actually built something like what I was thinking there....
Tubes hardly do anything for resistance, don't believe the hype. But you can purchase an extra thorn layer that goes between the tube and tire.
Seriously something like this
Forté Gotham ST Road and Mountain Tires - 700x32, 700x35, 26x1.75 or even
https://www.amazon.com/Kenda-KWest-K.../dp/B00LQFPNO6 at low pressure will ratchet up your resistance. And I'm not kidding a couple of bottle dynamos on tight will drag you down. You don't have to mess up your bike or buy/make a contraption. The watts from these two things are probably a pretty large fraction of your usual power output (superman legs aside).
