Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason

NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.

The flying car, AI, cold fusion, anti-aging.
Those are called helicopters. They're literally just cars but every advantage and every downside is amplified.
They're amazing for taking a small number of people somewhere, at massive cost to the surroundings. They're noisy, take up a lot of space, require lots of specialized Infrastructure just for them and they are incredibly dangerous to their surroundings.
That's not a technology, it's a scam. Regular fusion is absolutely real, it's just super complicated and hugely underfunded.
No, a helicopter is a flying vehicle that can't drive on city streets. A flying car is a street legal vehicle that can take off and land like a plane. https://youtu.be/a2tDOYkFCYo for an idea of what I'm talking about.
Doesn't matter if cold fusion is a scam or not. People keep trying to make it work which fits OP's question.
Nobody but quacks is trying to make cold fusion work. Are you confusing it with "regular" nuclear fusion?

Whatever.
