Reading Friedman at his best in this article on US Armed forces making big headway into green technologies:
Makes me sit up and think of how much US Defence has contributed to mankind. And NASA. Seriously and if they push hard, there inventions enter commercial markets making technologies cheap for civilian users.
As we go green, we need to start harnessing sunlight and heat, wind, tides and other such sources that are abundant and omnipresent. Oil should be one of the alternatives and not the only thing.
This large scale burning of gas needs to go down. Our earth is precious and we cannot afford to leave it high and dry.
