It sounds like science fiction but hear me out:
We should look into starting the research and development into High-Speed Trains that run on solar power with back up hydrogen batteries (3 storage backup batteries per train). Â It would be more energy efficient and faster than driving or air travel.
Â
With the system of the three backup batteries that are recharged via the train’s solar power system the train could rotate the depleting of the batteries one at time back into the new power grid. With two batteries fully powered at all times we would not have to worry about the train not having power. Either from the solar power system or the backup batteries if need be. The trains could run along the right-of-way of the power lines and crisscross the country with train stations also plugged into the power grid so that the train’s power system can be used to feed back into the power grid throughout the country using the train stations as feeding stations for the electric power grid.
Â
If the trains are government owned then the electric companies could pay a fee for the solar power and that could help reduce the national debt. The possibilities are endless.
