Trouble is blowing in the Wind

The wind is an inexhaustible source of energy. But the full potential of wind cannot be developed unless engineers understand the problem they are solving. A brilliant engineer will come up with a brilliant solution, but if the solution is for the wrong problem—that would be a wasted opportunity. Wind engineers are doing a brilliant … Read more

Renewable (sustainable) Energy

Harnessing Earth’s energy one day at a time Life on earth is sustained by the light and heat of the sun Every day, 365 days per year, the earth is warmed by the power of the sun—the amount of solar thermal energy absorbed by the earth’s oceans in a single day is greater than the total thermal … Read more


Methanol — The OTHER Alcohol One of the many ironies of the environmental movement is that in all the talk and hype about renewable energy sources, we almost never hear about one of the oldest and most versatile of all renewables — methanol. There are plenty of discussions of hydrogen and ethanol economies and electric cars … Read more
