Patent ID: 8707698

Claim:
A method for harvesting energy from a source of pressurized hot water, comprising: a. providing a first organic Rankine cycle heat engine, including, i. a first boiler, a first turbine, a first condenser, and a first feed pump, ii. a first circulating loop connecting said first boiler, first turbine, first condenser, and, first feed pump, iii. wherein said first circulating loop contains a working fluid, iv. a first hot water line leading into said first boiler, said first hot water line configured to receive said pressurized hot water, and v. a first water return line leading out of said boiler, said first water return line configured to discharge said pressurized hot water after said pressurized hot water has passed through said first boiler; v. wherein said first organic Rankine cycle heat engine is housed in one or more portable containers configured to be transported to said source of pressurized hot water; b. providing a second organic Rankine cycle heat engine, including, i. a second boiler; a second turbine, a second condenser, and a second feed pump, ii. a second circulating loop connecting said second boiler, second turbine, second condenser; and second feed pump, iii. wherein said second circulating loop contains a working fluid, iv. a second hot water line leading into said second boiler, said hot water line configured to receive said pressurized hot water, and v. a second water return line leading out of said second boiler, said second water return line configured to discharge said pressurized hot water after said pressurized hot water has passed through said second boiler; vi. wherein said second organic Rankine cycle heat engine is housed in one or more portable containers configured to be transported to said source of pressurized hot water; c. transporting said first and second, organic Rankine cycle heat engines to said source of pressurized hot water; d. assembling said first and second organic Rankine cycle heat engines; e. connecting said pressurized hot water to said first hot water line in said first organic Rankine cycle heat engine and to said second hot water line in said second organic Rankine cycle heat engine, wherein said first and second hot water lines are connected in parallel; and e. passing said pressurized hot water through said first and second boilers in said first and second organic Rankine cycle heat engines, thereby transferring energy to said working fluid.
