The electric airplane will be an indicator that the battery has arrived for ground transportation. If a commercial airplane can fly 500 miles on a battery then a car can travel the same distance on the same battery. Technology creep is making a better storage battery for electrical motors with a quick recharge cycle making the battery a competitive alternative to fossil fuel engines. The world is only about 20 years away from an electrical storage solution for electric motors. Needed is a significant weight reduction in that battery and a short charging cycle for storing electrical power. The chemistry in theory has been found but the practicality of making the alternative cheap enough has not been found. But a promise has been made it can be done so a forward push for an all electric powered aircraft goes forward.
The electric plane isn't just a far fetched idea it is what is needed to come and the necessity is the mother of the electric power travel. Elon Musk and Tesla is pushing this need in a awe inspiring journey but has it advanced far enough to entice "others" to try a concept at Universities across the world?
Cambridge start-up claims breakthrough electric car battery that can charge in 6 minutes
We’re working on methods to make powders that are scalable and where 1,000 tonnes could be made quite easily in factories. We have a prototype now, and are moving toward commercialization early next year. The tests have to be validated beforehand.
It's a matter of time and 20 years seems about right to drop fossil fuels from the Scheme of Things (SoT).
The SoT gauntlet has been thrown down and that is where we are today. Many ideas are pouring fourth and the solar system's sun is the key to unlimited electrical energy to power the planet in its endeavors.
The earth only has to supply plant based lubricants/plastics to make it all work. I'll be dead by the year 2040 but you may enjoy the change to save the planet from global warming.
