Abstract
A combination humidifier and moving indoor sculpture is provided comprising a reservoir containing a body of water, an upright helix rotatable about its longitudinal axis, and means for pumping water to the top of the helix. The helix floats on the surface of the body of water, and the water pumped to the top of the helix flows down the helix under the influence of gravity adding humidity to the surrounding atmosphere and rotatably driving the helix due to the change of momentum of the water flowing down the helix.
Claims10
A combination humidifier and moving indoor sculpture comprising:
- a reservoir for containing a body of water;
- an upright helix, said helix being rotatable about its longitudinal axis;
- means for floating said helix on the surface of said body of water;
- and
- means for pumping water to the top of said helix whereupon water flows down said helix under the influence of gravity adding humidity to the surrounding atmosphere and rotatably driving said helix due to change of momentum of water flowing down said helix.

A humidifier comprising:
- a reservoir for containing a body of water;
- an upright helix, said helix being rotatable about its longitudinal axis;
- said helix comprising a body portion approximating the shape of a right circular cylinder, and at least one ramp disposed along a helical path on the exterior of said cylindrical body portion and extending generally orthogonally thereto;
- a toroidal-shaped float disposed at the bottom of said helix and surrounding said cylindrical bottom portion, said toroidal-shaped float supporting said helix on the surface of said body of water;
- an upright columnar structure defining the longitudinal axis of said helix, said helix being journaled thereon;
- and
- means for pumping water to the top of said helix whereupon water flows down said helix under the influence of gravity adding humidity to the surrounding atmosphere and rotatably driving said helix due to change of momentum of water flowing down said helix.
