What do you think he invented that few people know about??

The comments are very spirited on one of the two videos here.

Commenter RT had this to day about Tesla:

I think he was what you would call the mad scientist. brilliant but mad

Commenter RS is a bit more skeptical.  Here are his thoughts:

Too much of “there were blueprints”, “he claimed he has a flying saucer” etc….. If this would be possible at least the US Army would have one by now. 80 years later and no one came up the the same crazy, awesome stuff?? come on.. I am afraid it’s more myth that fact… unfortunately!!

What do you think are any of these worth examining?

Check back for updates in particular about the hyperloop as it looks like it is a go.
