Cap and Trade, the  driverless car, bitcoin, container shipping through the Northwest Passage, all ideas by dreamers who don't understand how the real world operates. 
The dreamers think they are going to be able to plug into a virtually free electricity source , paying for it by bitcoin while they sit in the back seat of the car.
Earth to Dreamers... The Government SURVIVES ON the tax revenues from gas sales so they are going to have to impose the taxes on other forms of propulsion to bring in the money.
As for cap and trade, well let's see. Give me a generous CO2 allowance ( never mind the other poisons we let loose) and I'll still pollute at the same rate but I will be able to buy unused allowances from companies that make Tofu or buy some from an organic  farm.
Interesting that we will still allow companies to belch smoke into the atmosphere while other countries develop capture systems that allow them to utilize and even sell off their poisonous by-products.
don't sign it Mr Wall
