I seriously doubt the viability of this, but I’m looking forward to being proven wrong.
Possibility for private planes, but none for commercial planes. Just imagine a commercial passenger plane or cargo plane that needed a giant amount of electricity and like 12 hours of charging in between every flight.
Then, for safety reasons you’ll need to have two batteries in case one goes bad.
You can simply do battery swaps. Plane refueling already requires heavy machinery and industrial scale. I bet battery swaps will be faster than refueling.
And, no more tedious fuel calculations, just charge it all the way up, it doesn’t add any extra weight to do so.
Oddly enough I do actually think a charged battery is heavier, just as a full hard drive is heavier. But not to a degree that would matter.
That article you linked is utter trash, but it is correct about battery weight of a charged battery…technically…very technically…barely.
Like, a 4,000 mah lithium battery fully charged should weigh about 30 picograms more than when dead.
To put 30 picograms into perspective; a single 5 inch long human hair weighs around 0.04 grams. Well that’s 40,000,000,000 picograms.
This is really great. Wendover Productions made an excellent video about electrification of flights a while ago.
Now the real question is: will world governments allow this Chinese technology into their countries? Protectionism is a
valid*public reason to deny it, but I wonder if denying Chinese tech under the guise of national security a last ditch attempt from big oil lobbyists?Or is that too far fetched and I’m just way to cynical.
It’s fetched, but not very far
You know. I’m tired of seeing images of ceos and executives who have done none of the work for technologies alongside a picture of said technology. Show me a picture of Devin and the other engineers who spent all the hours figuring it out instead.
