Yeh I saw this on the news a few days ago. Looks pretty cool, but all they are doing is levitating some water droplets using sound waves. Now I'm no scientist, but I don't think that sound waves alone would have enough force to propel a craft, let alone at very fast speeds. I agree with you, really cool, but no dice

This is really interesting. I wonder what the direct result would be if they could make speakers strong enough and find the right frequency to float a 'human' like those water droplets. You would likely end up looking like hamburger. Since the early 80's, urologists have been using lithotripsy to smash gallstones and kidney stones into fine sand so they can pass out of the body in urine. The procedure involves high intensity acoustic pulses being focussed on the stones. They have the consistency of hard chalk and when the treatment is done they are reduced to powder. The procedure requires the... [More]

Does chanting a sacred mantra calibrate the molecules of the human body?

Rocket engines currently in use work in both atmospheric and space environments. Why don't you fire your idea off to NASA for evaluation. They usually reply to such suggestions. NASA already has significant work underway on alternate propulsion systems by their private sector contractors. You will probably find research on your idea is well underway, or has already been deemed unfeasible and has been abandoned. Not really what I am talking about, which is conventional travel, rockets provide lift. It goes in one direction very fast. It would be expensive to modify the design to allow conventio... [More]

It is not my idea, I just believe it has great potential. Not sure how you got that impression. Sorry,I think when I wrote that I was referring back to the original poster. My goof.

The procedure involves high intensity acoustic pulses being focussed on the stones. They have the consistency of hard chalk and when the treatment is done they are reduced to powder. The procedure requires the patient to be under anaesthesia because the shock waves are so powerful they cause cavitation in tissue and bone. And thats at a power that won't make you fly! Back to OP, though, have ... [More]

Back to OP, though, have you considered the fact that most UAPs that accelerate at high speed almost never cause sonic booms. Just a coincidence? I've always wondered about this detail. Hi 'archernyc'! Yes I have pondered this conundrum on many occasions, and believe that the answer to that particular achievement may lie in the general symmetry of the craft. In fact, we ourselves may not be all that far from cracking the sonic boom nut, as the clever young boffins at the TohokuUniversity are eager to prove... http://www.designcru...-boom-entirely/ Cheers.

I bet this particular item causes lots of UFO reports. LOL!
