The search for anti-gravity propulsion
(www.freethink.com)
This is a most excellent place for technology news and articles.
Without clicking on it, on a scale of 1 to Deepak, how much crank bullshit is this?
If it cites Tesla, I'm out. That one is a very reliable crank physics red flag.
It's a very interesting excursus of all the research, patents and theories that history has seen.
It is probably the opposite of what you think it is.
I recommend it.
