Ivory tower? 😃😃😃 Has anyone ever asked what we wanted? No. Industry rules the world. Big oil lobbied and bribed Congress and stopped any access to alternative. Too many billions of bribes available for to buy stupid greedy legislators with IQ's smaller than their belt size. Oil will be the only fuel on earth forever till either we are dead from the poisons they fill their bank accounts with or some mental midget blows us to hell and back to be oil king. Either way its to late, but it still pisses me off when I read of constant polluting by these mental morons so they can be rich and famous with the brumps of the world.
