Title: Innovations of Charles W. Haldeman
Introduction
Charles W. Haldeman is a notable inventor based in Concord, MA (US). He holds a total of 12 patents, showcasing his significant contributions to the field of combustion technology. His work primarily focuses on improving fuel efficiency and reducing emissions through innovative water-hydrocarbon mixtures.
Latest Patents
One of Haldeman's latest patents is the sub-critical water-fuel composition and combustion system. This invention involves a water-hydrocarbon mixture that includes low-molecular weight hydrocarbons and between about 5% and about 70% water. The mixture is maintained in a gaseous state at a pressure below the critical pressure of the mixture. The temperature is kept above about 28°C but below the boiling point of water at the mixture pressure, and below about 450°C. This innovative mixture creates a local environment of water molecules that limits hydrocarbon polymerization and other undesirable side reactions. It ensures a faster and more complete combustion cycle, characterized by lower emissions of carbon monoxide, unburned hydrocarbons, and volatile organic compounds. The hydrocarbon component preferably consists of micro-droplets with a diameter of no more than about 1 µm.
