These days, electric cars are pretty much the norm and are becoming more popular each year. But do electric vehicles end on the road, or can we take them to the air? This is where electric airplanes come into play. But just how feasible are electric airplanes? Are they still decades away, or are engineers already working on it?
Are Electric Airplanes Possib?
It's evident that planes are bad news for the environment, spilling out copious amounts of CO2 every single day. With this form of travel posing a threat to our planet, it's natural for us to wonder: why can't we produce electric airplanes?
While it may seem that carrying hundreds of people at once is pretty economical, planes are huge, and, unlike a bus, they need to travel hundreds or thousands of miles. So, as you might expect, other considerations must be made beyond the requirements for smaller electric land vehicles, but the one thing linking them all is batteries.
Multiple airline companies have considered the use of batteries in electric planes, but there remains a problem: a battery with a huge energy output would be required to do so. But this is far from impossible. In fact, scientists have already started making big steps towards successfully powering commercial planes with an interesting invention: polymer ionic liquids (PILs).
A few years ago at MIT, batteries with double the energy yield of traditional lithium-ion batteries were developed, using polymer ionic liquid as an energy source. This is an amazing advancement, but these batteries need to be made lighter to suit air travel. After all, the weight of an airplane is a crucial element in its flight. That's why all airlines have weight limits on baggage!
Another element that must be considered is energy consumption during flights. An electric car can be charged at a station if it runs low on electricity during a journey, but an airplane cannot do this during flights over water. This would make transatlantic flights difficult if the batteries onboard couldn't power the whole journey.
So, what's the progress looking like so far? Has an electric airplane yet taken flight?
Are Electric Airplanes Already Being Developed?
In short, yes. Electric airplanes have been tested in flight already. And this was by no means recent. In fact, an electric airplane took flight back in the summer of 2015. The plane was called the E-Genius, and could only seat two people. It took the pilots from Germany to Milan and flew over the French Alps on the way.
There was even a flight that took place in 2009 over the Alps, but this was solar-powered, not battery-powered. Of course, above the clouds, solar energy is abundant, so solar power makes sense. Similar flights have taken place using solar power, such as Germany's Elektra One and Japan's Solar Impulse.
European aerospace company Airbus also attempted an electric airplane, named the E-Fan. This electric aircraft was first flown in June of 2014 at a British airshow. However, Airbus canceled production of the E-Fan in 2017, when the company decided to focus more on a hybrid craft rather than solely electric. This gave way to the E-Fan X. However, when the COVID-19 pandemic hit, the project was canceled again.
While these electric aircraft are certainly impressive, they can only carry a handful of passengers (usually the pilots alone) and do not travel awfully long distances. So it's important to keep in mind that larger commercial planes will need to carry a much larger store of energy to carry hundreds of passengers and travel longer distances, as this is essential for commercial airlines. Not everyone is in the market for a private jet, after all.
Will See Commercial Electric Aircraft Soon?
Air travel has come a long, long way since the Wright brothers' aircraft first took to the skies in 1903. But developing fully electric commercial airplanes might prove to be a crucial step in lowering our carbon footprint and saving our planet. So, when are we going to start seeing larger electric aircraft being developed?
Fear not; this is happening right now. EasyJet, a British airline, has partnered with Wright Electric, a relatively new American aviation company, to develop a larger electric plane that can seat 180 people. This still isn't as big as traditional commercial airlines, but it's a huge leap in the right direction. Both companies hope to have the craft available for commercial flight in the next ten or so years if everything goes smoothly.
So, despite past failures, airline companies still have a clear focus on developing electric aircraft, and it might not be too long before we see them fly commercially. What a thought!
Electric Flight Is Still Evolving, But It's Not Far Away
With consistent developments being made in the field of electric aircraft, and with the climate crisis becoming an ever-pressing issue, we can only assume that more and more companies will continue to invest in the endeavor of taking eco-friendly transport to the skies. Let's just hope the foot room is adequate.
