Collins and P&W Unveil Hybrid-Electric Propulsion Systems
Collins Aerospace has completed the preliminary design for a new 1-MW electric motor that will serve as a key component of the new Regional Hybrid-Electric Flight Demonstrator under development by its Raytheon group sister company Pratt & Whitney (P&W). The aircraft engine maker plans to start ground testing with the Collins motor later this year in preparation for the start of flight testing in 2024 in Montreal.

And not to put too fine of a point on it but if you insist on pushing EVs then by all means, use ONLY wind and solar to power them. If not, you are just trying to obfuscate the real source of your energy, which is primarily fossil fuels. I won't even dip into the dilemmas raised by having to resort to exotic materials sourced from not-necessarily reliable, or "clean" regimes to build your systems. Now, if you are willing to discuss nuclear then we have hope for making progress.
The idea is to transition the generation of electricity to renewable sources, not just solar and wind but hydro and nuclear as well. Where I live, in Upstate NY, more than 90% of our electricity comes from carbon free sources. But even if they use electricity generated by fossil fuels, EVs reduce emissions. Remember that perfect is the enemy of good.
The negative comments here remind me of the time in 2004 that a VP at the major international aerospace company I worked told me not to pursue opportunities with drone manufacturers because drones would never amount to anything.
Thanks but no thanks. I'll stick to Jet A1/JP-8 or AVGAS as the case may be. No charging stations in the clouds.
How many homes will go dark if this green crap continues? Why is Thorium energy never mentioned in the major news media? Ask anyone who as gone x country in an electric pickup "HOW WAS YOUR TRIP".
Sorry, but that is a ridiculous statement. Whether you choose to believe it or not, climate change is real. In 1989, a NASA scientist I knew told me that what worried him was that some models suggested that by the time we had unequivocal evidence of anthropogenic global warming it was already too late to avoid a climate catastrophe. There is good reason to believe that we have, indeed, past that point of no return. But we owe it to future generations to take the matter seriously. The U.S. is the largest emitter of greenhouse gas per capita in the entire world except for a few small oil-producing countries. Calling efforts to reduce those emission "green crap" is exactly the sort of ignorance we must overcome.
I've been hearing about global warming since the 80s and yet not one of the predictions they have made has come true. I won't deny that humans are having an effect on the planet but to peddle fear is not the answer on how to deal with it.
Have you read Isaac's Newton's Laws 0f Thermodynamics? It's written for scholars so you might not understand some of the big words you may encounter.
