摘要： A method and system (100) for measuring a surface tension of a liquid is provided. The method is carried out using an electrospraying apparatus (103) connected in the system (100). At a first step a voltage source (113) applies a voltage between a capillary (107) through which the liquid is drawn and an electrode (111) of the electrospraying apparatus (103). An ammeter (115) continuously measures current flowing in the system (100) and if no current or a current less than a predetermined threshold current is measured in the system (100), the strength of the electric field at the capillary (107) is increased. As soon as current is measured in the system (100), a reading of a parameter of the system (100) is taken, which is used to calculate the surface tension of the liquid.

摘要： A packed rock bed thermal energy storage facility is provided in the form of a pile of unconstrained rock that is free to expand and contract with changing temperature without creating significant stress. A hot fluid inlet and outlet space is provided above the bed and a cold fluid inlet and outlet space is formed by a grid and larger rocks, or by larger rocks only, that support the pile toward a bottom of the bed. Fluid flow can occur downward through the rock bed during heating of the bed and upward through the rock bed during cooling of the bed in a heat recovery cycle. The bed is completely covered by an insulated arched roof. The rock bed may be an enclosure having a roof, walls and a floor with a lower central region and somewhat inclined side regions extending at a gentle slope towards sidewalls supporting the roof.

摘要： A wave energy convertor (1 ) is provided comprising an elongate construction (2), typically a breakwater or harbour wall, located in a body of water having wave action associated with it with the waves moving generally in a dominant wave direction (10) and having a generally constant wavelength. A plurality of equally spaced chambers (20) extends along the length of the construction internally thereof with each chamber extending generally upwardly and having at or near its lowermost end (28) an opening (24) into the body of water. Each chamber communicates through a unidirectional valve (40, 42) respectively with each of a high pressure conduit (44) and a low pressure conduit (46) with the high pressure conduit feeding into an inlet to a turbine (56) and the low pressure conduit communicating with an outlet from the turbine. The length of the construction is approximately equal to an integral number of said generally constant wavelengths in the dominant wave direction. The construction extends from a bed (4) of the body of water to above a high water level (8) with the opening of each chamber being located below a low water level (30) of the body of water.

摘要： A method is provided for producing a wood infused liquid consumable. The liquid consumable is contained within a container (2, 40, 50) and is contacted with one or more wooden components (4, 42, 52) in order to enable a wood infusion process to take place. Said one or more wooden components are severed parts of an intermediate wooden sheet cut from a log (30) of wood by rotary cutting it tangentially from the outer surface of the log of wood in veneer fashion such that the intermediate wooden sheet has a thickness corresponding generally to the radial direction ('R') with respect to the log of wood from which it was cut. The wooden component or components have a thickness of from 0.5 mm to 10 mm, preferably from 1 mm to 8 mm and most preferably from 3 mm to 6 mm. The invention also provides wooden components suitable for use in such a method. The wooden components may be in the form of any of a wooden sheet, strip (or slat), rectangular cross-sectioned rod, or small block.
