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.

The gainsayers here sound like those who told the Wright brothers that their contraption would never fly.
Yes, "gainsayers" is an impressive word, but "naysayers" is much more impressive in this instance
Both apply.
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.
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.
Just like the Power Generation industries non-carbon based or very low carbon base fuel and power systems is a huge mistake of other then niche us. The Countries that final relies that the Drive for so-call zero carbon fuel and power systems is an economic desaster and embrace the Nuclear, NGas, and Clean Coal technology fuels will drive their economic to the top of the world economy. Until their is a battery that can be recharged in under 30 minutes and give the Aircraft a safe and reliable output of 4 hours their is only the very short haul market that maybe All Electric Aircraft can fit in successfully. Investing possibly Billions into all Electric Airtransport is a good feeling project at best, just as Wind turbines and Solar panels are for the National Grid. All electric airtransport is a bad business model and left up to research orgs like NASA to do the projects and publish the results. If anything, mini nuclear power system, maybe the All Electric Airtransport solution as demostrated by numberous Space probes and Mars Rovers.
