GTL, plus nuclear power generation and plug-in electric personal transportation. And recycled garbage/sewage -> methane, methinks.
FWIW, Buell Motorcycle Company is an aberration in American business. In 1983 Erik Buell didn't come up with a 5 year plan or a 20 year plan, he came up with a 200 year plan. He is not in the motorcycle business. He is in the personal transportation business.
This is especially ironic given the accusation they use an antiquated, old tech motor in most of their current motorcycles.
