Abstract
Abstract This invention relates to space vehicle where solar energy is used to generate steam, which in turn, propels the vehicle in space. A copper boiler is provided and a novel solar radiation condensing means is used to focus the sunlight on said boiler. Steam generated in said boiler is exhausted to the environment to provide a thrust for the vehicle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A space vehicle comprising: a. a large diameter outer sphere; b. a smaller diameter spherical copper boiler located inside and at the approximate center of said outer sphere; c. means for delivering water to the interior of said copper boiler; d. means for exposing said copper boiler to solar radiation and to a flow of electrical charges whereby steam is generated, in said boiler; e. means for delivering said generated steam from the boiler to the environment outside the outer sphere to thereby provide a thrust component and hence a propulsion force for the vehicle; f. said means for exposing the boiler to solar radiation and said flow of electrical charges including;
Claim 2
Dependent Claim

Claim 3
Dependent Claim
82 words
tapered cones mounted about the entire periphery of the copper boiler, 2. said tapered cones having their narrow ends adjacent said boiler and their wider ends eminating to openings in the outer sphere, 3. lenses mounted in the wider ends of the tapered cones substantially contiguous with the outer surface of the outer sphere, 4. tourmaline gem stones lining the side walls of said cones whereby a piezoelectric effect is generated upon solar energy impinging on the side walls of the cones.
