Limbaugh debate with guy in Philadephia

I don't listen much to Limbaugh anymore, but today was rather slow, so I listened.  He got into a debate with this guy in Philly about global warming.  It is an example of the kind of thing that I argue against.  It is largely a useless exercise.  Instead of butting heads, try solving the problem.

What he could have done is ask the guy what would he do about this "problem".  If all he can say is higher prices for carbon, then Limbaugh could have just dismissed him.  Nobody in their right mind wants to pay more for energy.  Besides, it isn't even necessary.

If you really want to do something about carbon, here's two things the government could do:

1. Accelerate the adoption of LFTRs.  They could be used to manufacture carbon free fuels, like ammonia.  LFTRs don't have to compete directly with established nuclear facilities.  But eventually, they could replace them.  In the meantime, they can replace carbon fuels for cars.
2. Secondly, accelerate the mining of asteroids for platinum.  The platinum can be used for hydrogen fuel cells.  For instance, the government could guarantee a price for all the platinum that could be mined this way.  

These two initiatives could eventually replace a significant portion of carbon based energy forms.  It wouldn't happen overnight, but it would happen eventually.  And you wouldn't need a carbon tax or trade carbon credits in order to accomplish it.
