Spring is here, which means I'm back on my bike… burning rubber on the open road. Speaking of burning things, I want to take a moment to talk to you about one of nature's most profitable dirty-little secrets: coal.

I've shown you how to profit in oil. Then, I led you down the path of profits in what I called "agflation." Today, I'm going to show you how to make a bundle burning coal.

Coal is the next great commodity. Not solar panels. Not windmills. Not triple-A batteries or algae.

Good old-fashioned coal. The same by-product that we've all been digging for and burning for centuries.

It may not be the cleanest form of energy, but with oil spiking at more than $100 a barrel, the world is turning to coal to heat its homes, run its factories and keep its employees on the clock.

Whether you like it or not, coal is King. It always has been. And it always will be.

Burn Baby Burn!

For eco-conscious Americans, we don't like to talk about coal unless there's a miner trapped underground somewhere in West Virginia. It's dirty. It smells. It ruins the environment.

This is all true.

But when you sit back and think about the overwhelming global dependence on coal, and the profits you could be making, the numbers are simply mind-blowing.

See, dirty coal can easily get converted to liquid K-fuel. And in this form, coal from the Rockies can get to electrical plants in say, India, where their inventory has dipped to just seven days.

In fact, India remains entirely dependent on coal (in the form of K-fuel) to meet its rapidly growing demand for electricity. Yet, it has not one single mine.

Here in the U.S., we mine coal in more than 38 states.

As for China...
