Actually, when computer data travels wirelessly (WLAN, etc) it is essentially wireless electricity, although I don't really like that term for it.
Wireless electricity is possible, it just isn't very efficient. It takes very large amounts of power to do so. Think of radio stations, cellphone
towers or satellites, for example; they are sending out high-frequency electromagnetic waves that your radio or phone can pick up on a receiver. The
sources are transmitting a lot of power, though, especially if you want to send it more than a very short distance away.
And yes, Tesla did do some work in this field, though from what I understand, he didn't get too far with it. Basically, the process is just too
inefficient to be practical. Far from being free, it would be way more expensive than anything we have already.
I have no idea what you mean by 'wireless water', though... (unless I misunderstood something, as I strongly suspect)
