(interest conflict, I worked hard on a HaD project [0])
Maybe to rent stuff.
HaD is about a wide range of stuff, some extremely important (wheelchairs for ALS patients) to some absolutely funny and other completely ridiculous (but real achievements like CPUs in relays).
People might be interested in a them, but building them is often not easy, plus for each gadget you need place to store them and 20 times that place for the very specialized and costly tools to make them.
Renting them might be attractive.
