Wave energy, a promising source of renewable power generation, is unlikely to make a material contribution to US or global energy supplies unless more cost effective and robust technologies can be developed. Oscilla Power, Inc. has developed a technology for the low cost, utility scale harvesting of wave energy enabled by novel magnetic materials that has no moving parts. Following successful labo ...

Solid Oxide Fuel Cell (SOFC) technology promises to provide an efficient method by which electricity can be generated from coal-derived syngas, biofuels, and natural gas, while increasing energy security and reducing greenhouse gas emissions. The large capital costs attributed to the cathode low performance and long-term stability issues are a current limitation of SOFC technologies that must be a ...

Accelerators used in synchrotron light sources require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime electrical power. We will review available transistors, analyze high-efficiency power-amplifier techniques, and experimentally evaluate candidate amplifi ...

The materials and structures for fusion reactors must function for a long time in a uniquely hostile environment that includes combinations of high temperatures, reactive chemicals, high stresses, and intense damaging radiation. Manufacturing of components, particularly joining of materials, has been addressed as one of the critical issues. This Small Business Innovation Research Phase-I project i ...

This Small Business Innovation Research Phase I project will study the feasibility of a novel contaminant-tolerant solvent/stripping chemical hybrid process for post-combustion CO2 capture from utility flue gas. The process will use a proprietary solvent technology to achieve DOEs goal of 90% or greater CO2 emissions reduction at existing coal-fired power plants with no more than a 30% increase in ...

There is a growing need for new SPM techniques that provide additional information about the sample with higher data rates. In microwave harmonic scanning tunneling microscopy (MHSTM) a microwave signal is coupled to the STM, and several harmonics that are generated by the nonlinearity of the tunneling junction are measured to provide spectroscopic information about the sample such as identifying ...

Coal gasification plants have exhibited sub-par performance and plant economics due to poor reliability and availability. A major contributor to the poor performance has been fouling of the syngas cooler located downstream of the gasifier. The fouling is due to vaporized ash from the coal gasification process depositing on the fireside surface of the tubes in the fire tube heat exchanger used for ...

Certain types of specialty peppers may be desired by chefs. Capsicum baccatum, a relative of peppers commonly grown in the U.S. A, is a diverse species; both wild and cultivated forms occur in South America. However, cultivation of C. baccatum outside of South America is rare, and little scientific information is available with regard to cultivation of these relatively primitive cultivars of peppe ...
