Future cars will be folded and run off solar energy



San Antonio Light newspaper :
In the future, cars would be run off solar energy and would be able to be folded up into portable packages. According to the paper, the car’s engine would be able to be detached and carried to any local repair shop for service. The engine-less car could then be folded up and stored under the bed or in a closet until the repair is complete.
The paper cites recent advances in metallurgy as reason to believe that future cars will be made of super light weight yet equally strong (if not stronger) materials. The folding car has never since been attempted and they still weigh far too much to be carried off the road by mere men. We do, however, have fully functional solar powered cars, impractical for widespread use as they might presently be.
