Last time is CNG bus, now is Electric bus...
Why not ask our local universities to create a bus that runs on
solar power?
Solar power is free and does not emit anything.
If we install solar panels on every bus, each bus can supply its
own power and we can save on charging stations.
However, the problem is how to generate enough power even with
minimal sun light, and how to off the solar panels when enough
power is generated.
It's not simple, but imagine how much money we can make if we
create a solar-powered bus, patent it and commercialise it.
