The technology business magazine Fast Company
has a list
of what it considers the most interesting and promising emerging technologies, from blimps and gliders used as portable wirless broadband antennas, to washing machines that use negative ions in place of water and detergent, to scented plastics, to "galvanic vestibular stimulation" (delivering a light electrical charge to the small hairs of the inner ear to control equilibrium). A slideshow
is also available.
