Abstract

Some embodiments include a mounting system for mounting the device in a fluid, an axle fixed to the mounting system, a solid walled hollow body that rotates about the axle having axial symmetry about a longitudinal axis. The solid walled hollow body may be substantially rounded at the front, expanding to a maximum diameter less than half the distance from the front end to the back end, and tapering radially along the longitudinal axis to the back end. The energy device may further comprise a plurality of blades on the exterior of the hollow body, each blade extending from the front end of the solid walled hollow body to the back end, rising to a maximum height, and having concave and convex walls.

Claims

1. An energy conversion device comprising:

a teardrop shaped structure with 4 snap-together main exterior body parts consisting of;

a snap-in solid front end cap, two symmetrical solid walled upper and lower teardrop shaped central body parts with dovetail slots and snap-in dovetail key connectors, hollow cavities facing one another, and a snap-in rear end cap

multiple curved blades protrude from the exterior, spiraling the full length of each of the 4 main snap together parts

additional electric and electronic components are housed in the cavity of the two central body parts.

2. The energy conversion device of claim 1 further comprising one or more bearing assemblies fixed to the solid walled hollow body to allow the solid walled hollow body to rotate about the axle.

3. The electric component of claim 1 further comprising:

a generator housed in the interior space of the solid walled hollow shell.

4. The electric component of claim 3 comprises:

a generator housed between the walls of the hollow cavity of the 2 body parts;

the generator further comprises a contoured exterior walled rotor;

the rotor exterior wall has the same contour of the interior walls of the 2 body parts and is held in place by the compression between both central body parts.

5. The electronic component of claim 1 further comprises an energy storage device.

6. The energy conversion device of claim 5 wherein the energy conversion device is a battery attached to the shaft stiffener.
