Here is a concept for a futuristic transport device I made up. It is supposed to be a four-legged walking transportation device. It's much more stable than the typical biped mechs you normally see in movies and games (e.g., Robocop or the MechWarrior series), and their length allows them to travel much farther without draining too much energy. Cryodynamic (crystal powered) batteries on each leg support it and give the device power. Although, I'd imagine something this efficient would cost somewhere in the sixth or seventh figure, so these would most likely be in the hands of the rich and powerful.
