Fran thinks big

Instead of tilting at windmills, the dairy industry should think big.

If cows are housed indoors for much of the time, their poop can easily be captured for commercial biogas.

And while they are about it, why not invent a gas exchange system to extract methane from the air inside cowsheds.

We could even follow the Swedes and run a railway on biogas produced from digesting the parts of cows that usually get discarded at slaughterhouses to extract residual methane.

The big upshot is our tourism industry will also be protected. And I will get my fishing back.

Is this genius or lunacy? Or both?
