Electric cars are changing the market and their fuel is free
The ease at which we convert solar energy into electricity and the batteries we store the energy on are getting so good that they will most definitely power space travel. This is not to undercut the value of thermal energy storage, which could resist magnetic disruption, but would be (arguably) too hot to carry. As batteries fluctuate from lithium to aluminum to carbon, we're realizing we can travel vast distances on stored sunlight, and recharge in proximity to a star.
So, solar cars make sense.
Tesla's electric charging stations charge your car for free. It's a statement that changed the entire energy industry. Nissan went on a massive free charging station building spree and the trend sparks.
You will never need to pay for gasoline again because stations run on stored solar power that "charge Model S in minutes instead of hours," according to the their website. In August of 2014, Elon Musk, CEO of Tesla Motors, mentioned that they might produce a 500 mile per charge engine using graphene upgrades.
Free energy to move around is a small price to pay for growing a business. The investment in free charging stations is a testament to what Nikola Tesla would have done.
The price continues to drop for electric cars, with the new Tesla Model III to cost $35,000. Imagine buying a car and never having to pay for fuel again. Nissan, as well, went on a massive free electricity building spree with its "no charge to charge" program.
Bypassing a problem by writing a new equation about the way the world works is an art of genius the the car market embodies. When there is a bad thing, you build a good thing to counter it, and solar powered, emissionless vehicles, are an example of that.
