In an effort to circumvent the dismal power-to-weight ratio of batteries
which limits what modern-day prosthetic limbs can do, a team of
researchers at Vanderbilt have developed a
power source based on the burning of hydrogen peroxide.
The result is a 450 degree F jet of steam
used to fill cylinders providing linear motion which is then
converted into joint movements. Strength and speed are
increased by a factor of 3+ beyond what existing commercial limbs
can deliver.
