Abstract: A fuel delivery system for a liquid-type fuel cell and method of use are disclosed. The fuel delivery system includes a fuel tank and a fuel controller. The fuel tank stores a concentrated fuel, which is delivered to a chamber containing a diluted fuel. The fuel delivery is controlled by the fuel controller such that the fuel concentration of the diluted fuel is maintained in an optimal range.

Abstract: Systems and methods are described for providing an incentive to potential consumers who receive e-mail advertisements or other content to render the advertisement on a display or a printer. An advertiser distributes a content packet to one or more consumers. The content packet includes a message and a value that the consumer will receive if the consumer renders the message. The content packet also includes a message identifier for tracking purposes and a bank account identifier that identifies an advertiser bank account. A pre-configured rules module on a consumer device determines if the message will be rendered according to the value assigned to the packet. If the message is rendered, the consumer notifies the advertiser bank that the message was rendered according to instructions contained in the packet, and the value is transferred from the advertiser bank to a consumer account. A sensor on a consumer printer is used to verify that the message was printed.
