There's been a lot of interest in Tesla floating about the community, with some of his more popular accomplishments (or claims depending on who you ask). What I'd like to see happen now is for some new ideas to crop up.
In the interest of being thorough, I'll say that the Tesla turbine (and quite a few uses for it) has been done a few times over, and the wireless power is one of the more popular goals as of late.
Don't get me wrong, I'm definitely not trying to dissuade anyone from exploring any ideas that have "been done." Rather, I would just like to see what can be done about some of the other ideas, like ball lightning, the earthquake machine, or even an exploration of his work in radio, or any other topics.
So, to summarize, if you know of any of his ideas/claims/patents/inventions or whatever, feel free to at least post the idea here, and if you feel obliged, give it a go in an 'ible.
Cheers, and good luck!
