Abstract: A solar power generator for generating electricity from sunlight in which a photovoltaic panel is provided so as to be oriented for minimising exposure to direct sunlight. A heat absorber is provided, together with a filter for receiving sunlight and filtering ultraviolet and visible light components to the photovoltaic panel and infrared components to the heat absorber. The heat absorber may include a thermoelectric module.

Abstract: A method for producing an activated nesquehonite includes activating one or more nesquehonites by heating. The one or more nesquehonites may be formed by the reaction of carbon dioxide with aqueous magnesium ions at elevated pH, and may include barringtonite, nesquehonite, dypingite, hydromagnesite, and/or artinite and/or lansfordite. The activated nesquehonite may be useful in a building material, and have advantageous cementitious properties.

Abstract: A thermoelectric module for use in a wall of a building, the thermoelectric module having a heat absorbing side and a heat dissipating side and including a plurality of thermoelectric legs extending there between. The thermoelectric legs are supported by channels provided in the support member. The legs are provided with heat absorbing interconnects and heat dissipating interconnects. The temperature difference across the thermoelectric legs causes electricity to be generated.

Abstract: The present invention concerns fuel production apparatus for use with a combustion device. The apparatus comprises a fuel cell (12) for generating a combustible gas for combustion by said combustion device and power supply means (6) for said fuel cell, said power supply means comprising means for converting energy from a source of waste energy (2) associated with the combustion device into electrical energy for powering said fuel cell.

Abstract: A dynamic insulation system suitable for deployment within an envelope or facade of a building or habitable construction is described. The system comprises one or more layers of insulation and one or more void space forming elements (5,12b). The void space forming element comprises a panel attachment means (6) for connecting this element to a layer of insulation and a spacer element (9) that provides a means for defining at least one void space within the envelope or facade to facilitate the uniform, bi-directional, actively or passively driven flow of ventilation air through the void space. The resultant dynamic insulation systems can be made directly from any commonly available insulation sheet material, or combination of materials. This reduces the costs of the system without sacrificing performance or versatility. The system can be cut to any dimension, and joined together without loss of functionality to maximise insulation coverage of the building envelope or facade.
