Why hasn't anyone invented solar/electric combo cars yet? I know there are electric/gas combo cars and even just electric cars, but there should be cars driving around with solar panels instead of sunroofs. It would look cool and be amazingly earth friendly to be running cars off of solar power with battery back-ups. No emissions, totally renewable energy sources, especially if the electricity back-up could be derived from wind or solar power too. The car runs on solar power during the day, and can harness and store solar power for night time driving, or can run off the electrically charged battery back-up. People can install more windows in their garages to allow for more solar energy to come in and charge while parked inside. Or install a solar panel on their garage roof to provide power to the car parked inside directly.
Why isn't solar power more affordable and more widely used? Why aren't all the parliament buildings totally fitted and getting all their energy from solar power? Set a good example, government. If you're going to spend huge chunks of money on stuff, make it solar powered stuff, at least that wouldn't be throwing it down the drain. Lower the cost of solar power equipment so that it's widely accessible to all people. Utility companies, restaurants, places of business, government offices, or any offices should be running off solar power. It's the sun, man. It's not going to burn out any time soon. It doesn't freak out just because we find ways to use its energy. It's not like an old shirt, it doesn't feel or show stress the more it's used. It needs to be harnessed more and made available to the everyday person's advantage.
I'd buy a solar powered car. They really should start working on that. Or maybe they have and I just am not in the loop. I'll be watching for it. Surely if we can send people to space, we can make a converter of some kind that can turn solar power into energy for vehicles to run off of. It seems so obvious.
