energy

Current energy developments turn our thoughts to the possibility of future innovations. For example, is there a way to generate energy, usable energy, from fusion? Is there hope that this energy can be created and made available to the heat treat industry and other sectors? There seem to be many, many questions that have yet to be answered in the production and utilization of fusion energy.

John Clarke, technical director at Helios Electric Corporation, holds out confidence in the future by standing on the foundation of the past. Comparing the current position of science and research on fusion energy to the early days of aviation exploration, he thinks the sky is the limit for what can be accomplished.

On December 5, 2022, scientists at Lawrence Livermore National Laboratory conducted the first controlled fusion experiment in history. This experiment produced more energy from fusion than the laser energy used to drive it. In this test, the nuclei of two lighter elements were combined to form one new, heavier nucleus. During the process, some of the mass of the lighter elements was converted to energy.

How will this incredible breakthrough affect our lives? Will the promise of limitless, clean, and cheap energy be realized, and if so, when?

I don’t think we can know the answers to the above questions with certainty.  It has always been difficult to foresee the final results of any technological leap forward, and even more difficult to provide a timeframe that encompasses the change.

Think about a time before jumbo jets and commuter flights. That was a time when not a single person had been carried by airplane through the skies. History shows that scientists and thinkers were able to come up with ideas and machines that flew through the air while carrying many. Look at a brief overview of how quickly the aircraft improved.

On December 17, 1903, at Kill Devil Hills, near Kitty Hawk, NC, Orville Wright completed the first powered flight of a heavier-than-air aircraft known as the Wright Flyer. The flight lasted just 12 seconds, traveled 120 feet, and reached a top speed of 6.8 miles per hour. 15 years later, we saw the first airmail and scheduled commercial service. 24 years later, Lindberg flew across the Atlantic. 36 years later, we witnessed the introduction of jet engines, and Chuck Yeager broke the speed of sound just 44 years after the first flight in North Carolina.

Obviously, Orville and Wilber Wright would have had difficulty foreseeing the aircraft's advancements and would never have predicted a time frame. Why is timing the rate of advancement so difficult?  Airplane development benefited from the convergence of multiple independent and unrelated technology, and there was the will to develop more advanced aircraft for both military and civilian use.

So, back to the first question posed – will the promise of limitless, clean, and cheap energy from fusion be realized? I am going to say yes. Not that I know much about fusion, it is simply that history teaches us not to bet against technology. As for when, well that is a known unknown.
