a laser, microwave, radio, or infrared link would be much safer although
more $$. consider ham radio - licensing required tho.
the safety issues mentioned are real and should not be ignored.
if this is a "just for fun" project it is probably not worth the $$.
if it is essential check with a qualified networking professional and
perhaps an electrical contractor.
