65799 A whole-tree harvesting system would significantly reduce the cost of cutting, loading, and handling farm-grown hybrid trees for use in the biomass energy production industry. To continue progress in the development of the whole-tree harvester, this project will develop automatic controls for the steering and tree accumulator systems. In Phase I, automatic control systems will be designe ...

65181 The consumption of plastics costs our nation the energy equivalent of 1 million barrels of oil per day and accounts for more than one-eighth of our accumulating landfill burden. The most significant obstacle to a viable infrastructure for recovering these lost resources is finding a means to rapidly identify the polymer resin composition of recycled plastics. No method now exists that ...

65706 Negative-electron-affinity (NEA) photocathodes, which produce polarized electrons, are a vital component of electron accelerators. For the next Linear Collider (NLC), the polarized electron beam intensity must be at least 20 times greater than that produced by strained GaAs, used in the current generation of photocathodes. Additionally, the degree of electron polarization needs to be i ...

60972 Cadmium Zinc Telluride (CdZnTe) is an important material for detectors used for national security. However, the production of CdZnTe, dominated by the High Pressure Bridgman technique for a decade, has suffered from low-yields (1-4%) and small device sizes (1-3 cm3). This project will develop an alternative Modified Vertical Bridgman, CdZnTe crystal growth technique with higher yiel ...

Automobiles (cars and trucks for instance) are the predominant mode of transportation in the United States. These vehicles are powered by internal combustion engines that consume fossil fuels such as gasoline. Improving the efficiency of internal combustion engines is an ongoing challenge of enormous impact to energy consumption in the world. In order to improve engine efficiency and thus fuel eco ...

The primary challenges for creating renewable fuels are the ability to process inexpensive non-food feedstocks into biofuels that meet all quality specification, perform indistinguishably from petroleum-based fuels and are compatible with current infrastructure.Our Phase I project demonstrated the feasibility of producing biofuels from waste greases using a novel hydrothermal, continuous-flow cata ...

In topic 11.b, Dispatchable Geothermal Operations, DOE seeks to enable more widespread deployment of geothermal as a dispatchable energy source.TerraCOH’s CO2 Plume Geothermal (CPG™) and Earth Battery™ technologies are ideally suited to meet DOE’s needs.Conventional geothermal power technology has generally been limited to use as a baseload power source, but with increasing penetration of ...
