These inventions are incredible! Why? Because they are based on lived experiences (like old age) and needs (like the need to get out of a building fast). Because they function so well for the places and activities of daily life. AND because they are so beautiful! The combination wheelchair foldable bike is genius (exercise for the caregiver)! And who doesn’t want (need) a bike that is able to carry us over water as well as land as we commute to work? And that evacuation slide? It’s a work of art! Wouldn’t it be awesome in the MOMA?
