In my simpleton mind, I cannot understand why we do not use more blimps for transporting goods. Seems engines and fuel could be done with solar, also seems like they could be automated. Is it simply not cost effective? Is it dangerous even though modern blimps use helium? Eli5.

Solar power requires a lot of space to produce a large enough amount of energy to run a decent sized motor. That’s why you don’t see solar powered cars or planes.
