Solarpunk technology

Here's an amazing business plan: take the old designs for a railbus. Remove chassis, design a new chassis, but make it all futuristic. Show it to the investors. They'll say "but I want a pod!" And then you say "But it is a pod. A megapod, even!" And they'll squint and go "oh I see. Let's make 1000 of them."

(And actually this is exactly what people have done in the past. Cool futuristic exterior hiding what's basically just a diesel bus with train wheels.)
