Ocean Thermal Energy Conversion - Thermodynamic Analysis
Can ocean temperature gradients really generate useful amounts of electricity?The Global Warming Spiel
The concentrated energy from fossil fuels has given human beings great power and an apparent reign over the universe and the laws of thermodynamics. With high-grade energy, no more is man tied to the light and heat of the sun and weak power of his own muscles. Unfortunately, fossil fuels also happen to be part of Earth's carbon cycle and its atmospheric mixture of thermally insulating gases. Fossil Fuels gave us the power to build and multiply as well as the capacity to mess up the only home we have.Hydrogen Oblivion
Hydrogen is not a magic bullet. Contrary to popular belief, hydrogen is not a new source of energy, it is simply a storage medium for energy, like a battery. All people must understand this before we begin to our energy economy upon hydrogen.Alternatives to Coal for Electricity Production
Getting beyond fossil fuels and unsustainable consumption means understanding the capacity of the alternatives.The Coal Question
Some thoughts on using prehistoric carbonized trees for energy.The Exergy Crisis
Why we are "running out of energy" in a sea of energy.Compact Fluorescent Lighting Tips
Some Tips based on my experience with compact fluorescent lamps (CFLs). Fluorescent lights, when properly used, can save you (and the rest of the world) on the expenses of electricity.

The Great Balancing Act
Moderation of Consumption is the first step in a sustainable society. Stuff doesn't have to be Disposable to be Enjoyable.A Continuous Spectrum
Human sexuality spans a quite expansive spectrum, yet we continue to pigeonhole and stereotype, leading to confusion and distress.Consumerists
Our economy thrives on the concept of ever-increasing consumption, despite the fact that we live on a finite planet.Wood Gasification - Cleaner Energy For The Developing World
Gasification of Wood and other biomass in primitive and easily-built gasifier units and stoves can help bring more efficient energy to developing nations. Gasification offers a cleaner and more sustainable alternative to directly burning wood and dung.Techno-Fixes to Extend the Fossil-Fueled Oblivion
Often, we believe that we can maintain the status quo simply by using technology. While this may be possible in the short-term, it doesn't hold much promise for long-term sustainability.Treating the cause rather than the symptom
The Deepwater Horizon oil spill has brought energy back to the nation's psyche. Will the populace finally, en mass, understand the link to its own lifestyles and consumption patterns?

What is PMPO? It's An advertising gimmick!
PMPO is a measure of audio amplifier power output. It is deceiving because it considers an amplifier's power output under perfect conditions and only for a short instant.
