When the Wright brothers combined the right technologies they produced a feat that was, at that time, viewed as pure magic and not believed possible even after the fact. That was Human flight. Weather it's a bird or plane it takes energy to maintain flight the height. Trials have now demonstrated that perpetual flight by a plane is now possible, without the use any aviation fuel.
Oooh look! it get's better, as though that isn't enough there's this also.
I think this is pretty cool that solar power is replacing carbon based aviation fuel in this application. SS

Perpetual is a pretty long time. |

mooner and ss.....
As I am painfully aware at 81, nothing stays up forever. However the application of electricity powered propulsion systems to air transportation is not only probable, I believe it is inevitable. In fact I am currently betting rather large sums of money (large for me, not Buffet, Trump, or your average two-bit crooked politician - my "wealth" would be chump change to an average DC lobbyist or the mayor of Bell, California) on new technologies vital to the coming Energy Transformation. I feel the coming ET will be comparable in scope and effect to the invention of the internal combustion engine. Admittedly, the detail devil in this prognosis is the timeline.
Still, I am investing as large as I practically can in the future of electric propulsion systems - surface, marine, and air. I don't expect soon to see the Brayton cycle energized by some form of electrical discharge instead of internal combustion, but I do foresee the return of propeller aircraft driven by extaordinarily efficient electric motors powered by new energy storage devices currently in the developmental stage. As soon as electric automobiles demonstrate their mettle on the highways of the world, electric airplanes will soon follow. New battery chemistries and architectures and the final emergence of hypercapacitors (whether out of Texas or Beijing) will quickly initiate the demise of the ICE.
At least, these are articles of faith for me and investment goals for the last two decades of my life. |
