Total Claims: 5
Claim 1
Independent Claim
86 words
A novel growing unit comprising a walled enclosure, a predetermined portion of said enclosure being transparent to solar light, a circular water tank within said enclosure adapted to absorb said light and thereby provide a heat sink, a plurality of plant containers floating on the surface of said tank, and means extending from the exterior of said enclosure to the tank surface and being adapted to move said containers through a 360° path, at least a portion of which exposes said containers to the solar light.
Claim 2

A novel growing unit comprising a walled enclosure, a predetermined portion of said enclosure being transparent to solar light, a circular water tank within said enclosure adapted to absorb said light and thereby provide a heat sink, a plurality of plant containers floating on the surface of said tank, and means extending from the exterior of said enclosure to the tank surface and being adapted to move said containers through a 360° path, at least a portion of which exposes said containers to the solar light.
Claim 3
Dependent Claim
71 words
A growing unit as in claim 1, wherein said means to move said containers comprises a powered vertical member rotatably mounted substantially centrally in said tank, and having a laterally extending member attached thereto at a first end, there being a float attached to a second end of said lateral member, whereupon rotation of said vertical member urges said lateral member against said containers to move the same in said path.
Claim 4
Dependent Claim
19 words
A growing unit as in claim 2, wherein said vertical member is powered by connection thereof to a windmill.
Claim 5
Dependent Claim
