System and apparatus for transmitting a surface wave over a single conductor

A low attenuation surface wave transmission line system for launching surface waves on a bare and unconditioned conductor, such as are found in abundance in the power transmission lines of the existing power grids. The conductors within the power grid typically lack dielectric and special conditioning. Accordingly, the present invention includes a first launcher, preferably including a mode converter and an adapter, for receiving an incident wave of electromagnetic energy and propagating a surface wave longitudinally on the power lines. The system includes at least one other launcher, and more likely a number of other launchers, spaced apart from one another along the constellation of transmission lines. The system and associated electric fields along any given conductor are radially and longitudinally symmetrical.

A method of generating energy in a power plant (30) having a gas turbine (29), includes a first step a gas containing air (1) is compressed in a first compressor (2) of the gas turbine (29), a second step the compressed gas (3, 3a, 3b; 5; 7a, 7b) is fed to a combustion process with the addition of fuel (8) in a combustor (23), a third step the hot flue gas (9) from the combustor (23) is expanded in an expander or a turbine (10), driving a generator (18), of the gas turbine (29) while performing work, and a fourth step a partial flow of the expanded flue gas (11) is recirculated to the inlet of the first compressor (2) and admixed with the gas containing air (1). Carbon dioxide (CO2) is separated from the compressed gas (3, 3a, 3b; 5; 7a, 7b) in a CO2 separator (6) before the third step. In such a method, the overall size and energy costs are reduced by virtue of the fact that, to permit increased CO2 concentrations in the CO2 separator (6), not more than about 70% of the carbon dioxide contained in the compressed gas (3, 3a, 3b; 5, 5a, 5b; 7a, 7b) is removed from the compressed gas (3, 3a, 3b; 5, 5a, 5b; 7a, 7b).

Utilizing cash flow contracts and physical collateral for energy-related clearing and credit enhancement platforms

In accordance with the present invention, a financial instrument for the energy market is created. The financial instrument comprises a derivative instrument related to accounts receivable or accounts payable or both. In a preferred embodiment, the derivative instrument normally consists of two sets of linked swaps. In the first set, the seller exchanges two things with a third party: (i) the right for payment of accounts receivable within a month from the buyer is exchanged for the right to payment of such accounts receivable within a week from the third party; and (ii) the obligation to deliver energy to the buyer is exchanged for the obligation to deliver to the third party. The buyer exchanges the mirror image of those with a third party, to wit: (i) the obligation to pay within a month to the seller is exchanged for the obligation to pay within a week to the third party, but the buyer receives financing to offset the cash flow ramifications; and (ii) the obligation to take delivery from the seller is exchanged with the obligation to take delivery from the third party. The swap can further be utilized to net payment obligations under multiple cash and forward commodity transactions between the buyer and the seller. Physical collateral is utilized as margin. In accordance with another aspect of the present invention, the process takes place on a ‘clearing platform’ for such energy transactions.
