Abstract: This disclosure is of a system and method for using transaction cards to provide discounts to customers, where the customer initially funds the discount and then obtains a refund of the discount either simultaneously or shortly after the transaction.

Abstract: A platform connects customers and businesses for purchasing goods and/or services at a first price, which is less than a second price offered to the general public. Offers are made to customers through the platform under a first payment option or a second payment option. The first payment option is a pay now option where a customer pays for the voucher before receiving it, and the business pays financial consideration to the platform for the opportunity to provide the vouchers. The second payment option is a pay later option where the business pays no financial consideration to the platform for its offers. Customers pay a periodic subscription and receive the vouchers without payment. Payment for the vouchers occurs directly with the business at the time of redemption. Businesses may also be paid commissions for attracting customers to use the platform.

Abstract: The invention provides a system and method for the efficient, clean and simultaneous conversion of multiple fuels, including but not limited to waste derived gas, liquid and solid phase fuels, to electrical energy. The present invention used a closely coupled combined thermal cycle system based on an air fed gasifier and an internal combustion engine. Steam generated by exhaust heat from an internal combustion engine and from the combustion of syngas produced by the gasifier is used to power an admission steam turbine in an efficient system in which components such as water treatment, heat recovery, and other components are common to gasifier and the internal combustion engine. The invention offers several advantages over other combined cycle power plants employing gasifiers.

Abstract: Nozzle cooling and wall contact prevention control are included in a gaseous CRISLA apparatus, along with removable collectors, and the efficient use of one or more currently available high power lasers to produce a commercially economic isotope separation process. The wall contact prevention is accomplished with gaseous boundary layers, and a supersonic nozzle normally is used to cool and separate excitation bands of the isotopic material. Non-intermixing gaseous streams with different isotopic assays can be created in a single nozzle chamber and segmented collection chamber, which along with recirculation loops and compressors, allows a single laser system and a single nozzle system to be used to selectively excite the isotopic material while it makes multiple passes through the laser beams of the laser system until only a small fraction of the desired isotope remains to be separated. The process is especially effective in separating .sup.235 UF.sub.6 from a gaseous mixture of .sup.235 UF.sub.6 and .sup.
