A few? The goal of every business is market domination. You can’t charge this on 110v effectively. You need a 50 amp 220 outlet. Your solar panel would be dedicated to just charging the car. In attempt to revamp American energy into solar, Musk tried to convince us by saying that we have a “giant nuclear reactor in the sky.” Well that is true, however, its energy is diluted by distance, clouds/dust particles, and the sun is only visable 1/2 the year. Pretty innefficient reactor. I’d love to have a single solar panel connected to a small air conditioner in the summer, mini heater in the winter tho. Price is the problem. IMO, solarcity is a scam that feeds off fear driven environmentalists and banks on tax subsidizes. Solar price will come down with future tech, it’s just not there yet.
SpaceX is pretty cool and very impressive, but how will it make money? Maybe their future will be in weapons. They’re burning cash fast and with all their side projects, hard to say which one will be shitcanned first and which innovations will they have to trim fat off of and use cheaper tech on to recoup loss and provide a more affordable product.
