Abstract
Abstract The liquid metal sodium-potassium alloy called NaK reacts with water and air to release energy and to form hydroxides of NaK. The hydroxides are transported in solution by pipeline to be regenerated to NaK metal by electrolysis, the NaK metal being transported by a second pipeline to be dispensed to automobiles. The present invention is an internal combustion engine based on an explosive reaction of NaK and water sprays in the presence of air. A two cycle piston engine with NaK and water injected near maximum compression is preferred.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
In an engine having an internal combustion chamber and power generating displaceable engine means in said combustion chamber, the improvement comprising a source of liquid sodium-potassium fuel, injection means joining said source of fuel to said internal combustion chamber, a source of water, injection means joining said source of water to said combustion chamber, means to introduce oxygen into said internal combustion chamber, said heat of explosive reaction directly operating said power generating displaceable engine means, and collector means outside said internal combustion chamber to collect and store gaseous and hydroxide by-products of combustion.
Claim 2
Dependent Claim
94 words
In an engine having an internal combustion chamber and power generating displaceable engine means in said combustion chamber, the improvement comprising a source of liquid sodium-potassium fuel, injection means joining said source of fuel to said internal combustion chamber, a source of water, injection means joining said source of water to said combustion chamber, means to introduce oxygen into said internal combustion chamber, said heat of explosive reaction directly operating said power generating displaceable engine means, and collector means outside said internal combustion chamber to collect and store gaseous and hydroxide by-products of combustion.
Claim 3
Dependent Claim
23 words
In a combustion engine having the features of claim 1 wherein said means introduce oxygen as compressed air into the internal combustion chamber.
Claim 4
Dependent Claim
33 words
In a combustion engine having the features of claim 1 wherein said power generating displaceable engine means is a piston and cylinder assembly, including mechanical means responsive to the movement of the piston.
