Common type of rail car has dangerous design flaw

You're right about coal, Charlie. It can be made to burn as clean as natural gas and it would be not only more cost effective but also more practical to accomplish if the necessary modifications were made to power plants and other large users of coal. Once those users begin consuming natural gas, not only will gas prices soar, but the available gas will be used up that much more quickly. When it's gone, homeowners won't have the opportunity (or resources) to convert to coal heat.
Governmental foresight extends only far enough to retain ones personal position through the next election.
