2 x Tesla: 1) How feasible and safe are Tesla's ideas for wireless electricity? 2) How much truth is into that particle beam weapon?

I already knew a lot of stuff about Tesla but I just watched a documentary about him and I got interested in his work again. Halfway through the "documentary" I saw that it was mostly conspiracy stuff about HAARP and particle beam satellites, concealed as part of Tesla's mysterious life story.  

Now seriously, regarding wireless electricity transfer... How feasible would it be for use at home or office? To keep your phone and laptop charged without plugging it in anything for example... Or having a wireless mouse that does not require batteries. 

And about the weapons developed by Tesla, how much truth is in the stories about these things? I understood only that his idea of giving free electricity to everybody by tapping into the ionosphere was then used as an idea for just developing powerful weapons. I think these conspiracy guys are using the fact that Tesla was both a genius and a mysterious man, as a way of manipulating people into thinking crap like the secret weapons: HAARP and particle beam satellites... 

**Later Edit**: Thank you very much for the responses. It seems to me that Tesla's ideas are great and even if they could be applied, they're not better and they are certainly not more efficient than the current ones. I guess that Tesla wanted to give free energy to everybody by spending a huge amount of others' money. Also, it might be that some ideas were more feasible in the past, when the energy demand wasn't as large as now and you didn't have dozens of electronics and appliances around the house to power constantly...

The example of wireless charging is already in use. Over very short distances for very small loads, it's a convenience. Anything farther than that and it becomes a power sucking parlor trick. (not a problem when you're Tesla and have your own generators.)

As for particle beams, it suffers from the same basic problem. When using radiation as a weapon, increasing the distance to target increases the energy needed exponentially. It's probably possible (to some degree), but not efficient or useful. Remember that plane that fires a laser? It took 10 seconds of tracking a standstill car just to set its engine on fire. The plane could only fire it once per flight.
