Abstract
The present invention provides a viscous fuel, which includes a fuel substance held in a polymeric structure, where the viscous fuel has benefits over previous fuels, including performance enhancements and desirable physical characteristics. One embodiment of the formulation includes neat methanol, to which a thickening substance, such as that sold commercially under the trade name Carbopol®, is added to impart viscosity, as well as stabilizing and suspending properties. In addition to the thickening substance, a further substance can be added to balance the pH of the viscous fuel when needed.
