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.

Blimps can only be used in good weather. When that’s not available, your shipment is grounded. That sort of unreliable transport only works in a few industries, and they use trains for it. Blimps are very expensive relative to trains (though so are trucks).
