I'm still trying to understand how electric cars are an improvement. Electricity has to come from somewhere and mostly that means from fossil fuel power stations. Are power stations notably more efficient that internal combustion engines? What about the energy loss in sending electricity over hundreds of miles of power cables? If electric cars are more expensive to buy that's probably a sign that the energy cost of building them is higher.
I think I need a car analogy to help me understand this."
I thought Crayola were working a technology called colour-mixing? It's a bit like anti aliasing: you combine some of the 120 colours and suddenly it looks you've got new intermediate shades. There's probably an OpenGL function call for it.
