A new electric motor from H3X is claimed to be 3x lighter than other motors with comparable power ratings:

Groundbreaking H3X Motor Brings Electric Aircraft One Step Closer To Reality

The startup H3X says it has developed a compact electric motor that develops more than 3 times the power and weighs less than most commercially available motors. To be specific, the company claims its HPDM 250 motor has an output of 13 kW per kg.

I want this to be real, and after a cursory read-through suspect it could very well be. There's enough detail and engineering realism (and lack of investor hype) that this sounds believable. The push is in this direction anyway so it's safe to say we will see this or one similar fast-tracked into production. My hope is that battery and/or other energy storage mediums can progress in parallel with these electric motors. When we start seeing energy densities that compete with petroleum, the push to eradicate fossil fuels will be strong. I would guess the cost of gasoline will become prohibitive once EVs are readily available. The near future will be interesting.

We,ll have to repurpose our ICE's into generators.

Why not present images with dynostand and measurements?
