Funny you should mention this. Any new construction of Commercial sites for the last 2 years have always included Solar arrays. Around here, we have sunshine almost year round. Even in the Winter time. This is why you will see Snow Skiers in burmuda shorts in Feb. The bulk of the snow and cloud cover happens at night so the day is usually clear skies or near clear skies. Leaving out Solar Arrays from new Commercial Construction is just plain stupid. Since you have to pay for a roof anyway, put solar arrays instead of roof tiles. It doesn't cost that much more even when you include the wiring and controls. You start getting your money back the day you throw the switch even if all you use them for is to power your Offices and outdoor lights.
But I have shown that Solar isn't the only thing that can be used. And Fusion will be here in the next 7 to 10 years which pretty well takes over for all other forms of electric generation except for Hydro, Solar and Wind. NG, Coal and Oil become forgotten.
Your original entry into this conversation was could we use Electric Power for Aircraft. The answer to that was, YES. They are already doing it. And by 2025, commuter flights will be electric power for seating of 10 to 50 people that are now using Jet Fuel. And that is a very safe prediction.
We are in a very exiting time right now. Energy Technology is making a huge leap. It's been a long time coming but like all other science evolutions, it happens in spurts. Welcome to the latest spurt.
how heavy are the batteries in you electric airplane? How much wing span is needed to carry that extra weight? You are also talking about large heavy electric motors to generate enough power to turn props at the needed RPMs. Then when it lands those huge batteries need recharging, where will that electricity come from?
New technology is great and we should pursue all alternative power sources, but we also need to be practical and not get deluded into thinking we can get off of fossil fuels in the near future.
The electric motor is actually smaller and lighter than the Avgas motor. And the batteries like the Lipo4 batteries are lighter than the Avgas tanks full. While the HP of the Avgas at sea level will be higher, as the altitude goes up, the HP of the Electric will exceed the HP of the Avgas engine. The only real advantage the Avgas rig has is range,not power.
Believe it or not, we reached the pinacle of development of the gas and diesel engine in the 1940s. They are doing nothing today that wasn't already done during WWII during the war effort. In Recip Engines (Inlines) turbochargers were already perfected, so were superchargers. They could get outstanding performance on 87 octane. All they are doing is just tweaking the WWII designs that were near perfect already.
Meanwhile, the Electric was forgotten for nearly 100 years. Just plain ignored. At one time, (1903) at the World Auto Show in Chicago, the number one shown engine was the diesel while the number two was the electric with the steam running a distance 3rd. There was only one gas powered engine represented. In just a few short years, the Gas was the dominate one with the Diesel running a distant second and the electric and the steam were no longer represented. While I realize that the steam had no future as a car or truck engine, the electric did have but was completely ignored for the next 100 years. Meanwhile, the gas and diesel had that time to develop. Out of Necessity, the Electric is now getting the attention it should have received over 100 years ago. And it's starting to compete directly with gas. In about 15 years, it's gone from experimental to actually competing on a limited level. Not bad, really. Give it another 5 years and it's going to be able to go head ot head. Remember, the Gas engine really can't develop any further than it already has since it's peaked. The Electric has not peaked by far.
Don’t fix what Ain’t broke...
It's already broken. It was broken the day the first belch came out of the first smoke stack and the first puff came out of the first tail pipe.
Quit trying to control things that you can’t
