He bills himself as ?Nebraska?s Largest Citrus Grower?, an unusual title given Nebraska?s notoriously cold winters and relatively short summer growing season. But what started out as an interest in earth heating for a new home has evolved into a semi-tropical biosphere in the western panhandle of Nebraska.

harnessing the endless supply of geothermal energy


Endless?
If you think global warming is bad, wait till the earths core cools.

I hope you're being ironic. It was the failure of the earth's core to cool which was a major scientific hurdle to overcome before Darwin's theory of evolution could be accepted.

If the world was as old as Darwin was claiming to allow evolution to work it's way from simple to complex life forms and the full fossil record, then simple thermodynamics would indicate that the earth's core should have cooled to a frigid lump like the moon billions of years ago. It was only the discovery of natural radioactive decay of uranium et al which resolved the issue.

The core will be plenty hot enough for billions of years yet.
