NASA’s Physics-Defying Space Engine More Fiction Than Fact?

The history of modern physics contains several examples of crazy and successful new ideas. Unfortunately for scientists at NASA’s Johnson Space Center in Houston, their “impossible” space engine may not be one of them. Why? Simply put, it violates Isaac…

Encouraging Sustainable Energy in the Developing World

Societies will always need energy to develop and function; how this energy is generated and delivered will determine whether we can achieve a sustainable future. Today, approximately 40% of the world’s population, mostly in low- and middle-income…

Counting Spots: How Clean Are The Tar Sands?

-- Measuring, or what Richard Feynman called "quantitative observation" in his Lectures on Physics, is one of the defining features of science. Some scientists, most notably Steven Hawking, even believe that science is nothing but measuring – if…

Spinning electricity out of thin, moving air

The sun’s beaming rays heat the Earth, but not evenly. Many attributes of the Earth – such as its atmosphere, topography, bodies of water, and rotation – contribute to uneven heat distributions, which create air movement, or wind [].…

Electric Vehicles and Hybrids: Where are we now?

As President Eisenhower said, our “transportation systems are dynamic elements in the very name we bear—United States.  Without them, we would be a mere alliance of many separate parts.” (Pres. Dwight D. Eisenhower, Feb 22, 1955). The automobile became a…

Why We Need Sustainable Energy

The degree to which we use energy has far-reaching consequences. For example, the simple act of driving to work uses fuel that is ultimately tied to both international conflict and global climate change. The success of modern civilization is…

Black Silicon: Working around the current limits of solar cells

For many years, sunlight has been seen as a potential gold mine of useable energy for our global needs.  Having successfully used the sun to grow food to feed the world, people are now trying to harvest the sun’s energy and convert it into electric…

Synthetic Biology for Fuels

Fossil fuels are running out Since the mid nineteenth century, humans have progressively mastered the discovery, extraction, and combustion of fossil fuels. Fossil fuels are the remains of organisms, mostly thick growths of plants from more than 500…

Beyond the Debate: The role of government in renewable energy finance

Last year, the world invested more money in renewable energy than ever before, at over $257 billion [1]. There is no question that renewable energy projects need finance to develop and commercialize. According to the International Energy Agency (IEA),…
