A turbine blade includes a core element having a base portion, a tip portion, and an intermediate portion extending between the base portion and the tip portion. The intermediate portion includes a non-uniform cross-section and is a high-strength fiber material. The turbine blade further includes a shell disposed around the core element, and the volume between the core element and the shell forms a void.

Methods and articles are provided for generating electricity from carbon-based photosynthate produced by a plant. The methods include providing the plant with a composition including COand/or a composition that generates CO, harvesting a carbon-based photosynthate from the plant, processing the carbon-based photosynthate to produce energy, and converting at least some of the energy into electricity. An apparatus for converting the carbon-based photosynthate into COand heat, and an apparatus for converting the heat of combustion into electricity is also provided. An apparatus is also disclosed for providing the plant with a composition including COand/or a composition that generates CO.

Production of electricity from plants

Methods and articles are provided for reducing the amount of water consumed by a plant over a period of time, sequestering CO, and producing electricity, where each method includes providing the plant with a composition including at least about 0.1 (wt./wt. or vol./vol.) % COand/or at least about 0.1 wt./wt. % of a composition that generates CO. An apparatus is also disclosed for providing the plant with a composition including COand/or a composition that generates CO.

Described embodiments include a system and a method. A system includes an energy storage device configured to store and release energy. The system includes a waveform sensor configured to detect a second harmonic or higher frequency component deviation in a waveform of electric power supplied to the system by an electrical power grid. The system includes a bi-directional switched-mode converter coupled between the energy storage device and the electrical power grid. The switched-mode converter is configured to receive and convert electric power from the electrical power grid into energy stored in the energy storage device and to convert energy released from the energy storage device into electric power and discharge the converted electric power into the electrical power grid. The system includes a waveform correction manager configured to control the bi-directional switched-mode converter in a manner implementing a waveform deviation reduction strategy responsive to the detected deviation in the waveform.

A thermal insulator includes a plurality of layers. At least some of the layers include phononic crystals having a phononic bandgap, wherein heat transporting phonons within a selected range of frequencies are substantially blocked by each phononic crystal layer. The plurality of layers thermally isolate a first region from a second region, wherein the first region is at one end of the plurality of layers and the second region is at the other end of the plurality of layers.

Multi-layer phononic crystal thermal insulators

The present invention relates to a method of operating a fluid-working machine wherein the volume of working fluid displaced each cycle is selectable and wherein the volume of working fluid displaced by a first working chamber takes into account the suitability of the working chamber to displace fluid. The invention extends in further aspects to power absorbing structures such as renewable energy devices comprising such fluid working machines. The invention allows the operation of fluid working machines and power absorbing structures which are more long lived.

A ring cam for a fluid-working machine is formed from a plurality of segments. The segments comprise a leading cooperating formation which has a piston facing surface which forms part of the working surface, at a trailing end, and which is recessed from the working surface at a leading end, and a trailing cooperating formation which has a piston facing surface which forms part of the working surface at a leading end, and which is recessed from the working surface at a trailing end. The segments having piston facing surfaces which are in compressive stress such as to partially or fully compensate for tensile stress arising from the action of rollers in use. The segments form a wavelike cam surface and attachment means are provided, through the working surface, on whichever of the leading or trailing surfaces thereof is subject to lowest forces from pistons in use.
