Logos Technologies proposes to modify its multi-fuled, series hybrid-electric powertrain used in its acoustically-suppressed, powered parafoil, the DARPA ParaHawk, and integrate it into the existing off-road, electric motorcycle by BRD. By modifying and combining systems, Logos will significantly reduce risk and development time. Having demonstrated the hybrid powertrain in Phase I, Logos will quickly integrate the modified hybrid system into the BRD existing chassis for full motorcycle tests in Phase II. Logos Technologies believes that its proposed approach not only meets, but exceeds, the governments requirements. Unlike parallel hybrid solutions, a series hybrid can easily be adapted to provide power to both wheels, a silent-mode, and direct integration into other systems with complex layouts all known DARPA goals. With mass-market commercialization in mind, as well as constrained military budgets, Logos has focused its design on leveraging COTS components while exceeding the military requirements by integrating technologies BRD has developed specifically for electric motorcycles, including a very energy dense battery, high power dense motors, and a motorcycle data system as much as possible.

Logos Technologies proposes to modify its series hybrid-electric powertrain used in its acoustically-suppressed, powered parafoil, the DARPA ParaHawk, and integrate it into the existing off-road, electric motorcycle by BRD. By modifying and combining systems, Logos will significantly reduce risk and development time, demonstrating the hybrid powertrain in Phase I and then quickly integrating it into the BRD existing chassis for full motorcycle tests quickly in Phase II. The team will be able to rapidly commercialize the developed system through BRD?s target markets. Logos Technologies believes that its proposed approach not only meets, but exceeds the government?s requirements. Unlike parallel hybrid solutions, a series hybrid can easily be adapted to provide power to both wheels, a ?silent-mode?, and direct integration into other systems with complex layouts ? all known DARPA goals. Additionally, the demonstrated Logos hybrid system has a well-proven, multi-fuel engine quieted to well below the requirement, all the necessary power electronics and software for batteries and engine power sharing, and the ability to provide power to auxiliary systems. These capabilities will be improved through integrating technologies BRD has developed specifically for electric motorcycles, including a very energy dense battery, high power dense motors, and a motorcycle data system.


Provided is a semi-continuous fermentation method of a rhamnolipid producing microorganism to produce rhamnolipids. The fermentation may be run as a batch process but at the end of the fermentation, at least about 70% of the fermentation medium comprising one or more rhamnolipids is drawn out and the new culture medium (feedstock) is fed in as a replacement. This process may be repeated for at least about one month without having to sacrifice RL yield and titer. It allows the fermenter to be utilized at a higher capacity with less downtime for clean-up compared to batch and fed batch fermentation strategies.

The present invention relates generally to electric power and process heat generation using a modular, compact, transportable, hardened nuclear generator rapidly deployable and retrievable, comprising power conversion and electric generation equipment fully integrated within a single pressure vessel housing a nuclear core. The resulting transportable nuclear generator does not require costly site-preparation, and can be transported fully operational. The transportable nuclear generator requires an emergency evacuation area substantially reduced with respect to other nuclear generators as it may be configured for operation with a melt-proof conductive ceramic core which allows decay heat removal even under total loss of coolant scenarios.

Embodiments of a laser system having an extremely large number of small pulsed lasers for irradiating small targets in inertial confinement fusion experiments, high energy density physics experiments, and inertial fusion power plants is more flexible than existing laser systems. Embodiments facilitate finer control of critical features of laser pulses for inertial fusion, as well as significant reduction in development costs and expansion of the community involved in the research relative to existing laser systems. Embodiments produce smooth intensity profiles at the target, large bandwidth that is over two orders of magnitude greater than existing laser systems, and fine control over laser wavelengths, focal properties, temporal pulse shape, and illumination geometry. Properties of each of the small pulsed lasers are individually selectable.
