CFCs, PFAS, BPA, phthalates, thalidomide, leaches, bloodletting, lobotomies, pretty much the entire history of mental health treatment, hydrogen airships, vermillion pigment, mercury felt stabilizer, radium water... If I were feeling particularly spicy I might even suggest things like weapons research, communism, or suburbia.
- Vecr 3y agoHow bad actually are hydrogen airships? At this point trying to make tiltrotors any safer is not working out, so airships could be better. Though, if you have a real airport, passenger jets are unbeatably safe.
- itishappy 3y agoFair point! Probably should have left them off. Despite the rather famous failing, they've had a lot of utility, and the technology is still in use today. (I think there's at least one YCombinator startup using hydrogen airships.)
