Abstract

A wind turbine 1 is shaped to resemble a chimney pot, spins on a vertical axis and is connected to an electricity generator or alternator and mounted on a base unit (fig 2, ) that has attachment means to attach the base unit to a surface. The turbine 1 can comprise curved blades arranged around a vertical cylinder 2 with a downward sloping cone 3 at the bottom. The base unit (fig 2) can have ventilation holes 6 and fly screens 7 to ventilate the flue. The turbine can be mounted on a chimney/flue stack (fig 7) on a domestic residence.

Description

chimney pot electricity generating wind turbine This invention relates to a device that is an electricity generator that is wind powered and spins on a vertical axis and is designed to resemble a chimney pot when spinning by being the same size and shape as a chimney pot on a domestic home or residence, mounted on a ventilated base unit.

Most electricity generating wind turbines in use today spin in a horizontal axis, and are mounted on poles in the land surrounding the home or on poles attached to the side of the home, these however are often not the most open areas and do not get enough wind to power them and only one turbine can be used, which is a shame, as the more turbines, the more power can be generated, on top of this, these conventional turbine are often seen as ugly and unsightly items that may cause people in neighboring properties to object to their use, this concern, as well as the high price of the turbines means that few people are taking advantage of green method of electricity generation.

To overcome these problems the present invention proposes a wind turbine with its blades spinning on a vertical axis, with a profile shaped to resemble a chimney pot, attached to a short conical shaped base, mounted on top of the chimney/flue stack, this area being the highest point of a domestic residence, meaning that the turbine is in the most open and windy spot available, with a lot of chimneys now redundant, as people are no longer burning solid fuels as commonly as in the past, there is a opportunity to place more than one chimney pot shaped wind turbine on top of the chimney/flue stack.

The invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 Shows the turbine blades attached in a circle around a vertical cylinder, the outside edges of the blades shaped to resemble the profile of any domestic chimney pot with a conical bottom sloping downwards to prevent rain from falling between the blades on to the base unit Figure 2 Shows the round base unit with conical upper section with holes in it covered with fly screens to allow ventilation of the flue and restrict the entry of insects, attached to the top of the conical section is an electricity generating unit fitted in such a way as to allow the upper cylindrical turbine section to spin freely on a vertical axis once attached together figure 3 Shows alternate style of turbine blade figure 4 Shows alternate style of base unit figure 5 Shows alternate style of turbine blade figure 6 Shows alternate style of base unit figure 7 Shows turbine in position on chimney stack On figure 1, The turbine section which would spin freely in the wind, is made of several curved blades, which could be shaped to match any existing style of chimney pot 1) arranged around a single vertical cylinder 2) with a wide, shallow, downward sloping cone 3) at the bottom, which would have fittings on the underside to attach it to the base unit 4) On figure 2, The base unit which would be attached to the top of the chimney/flue stack has a flat, round, horizontal bottom section 5) for attachment to chimney/flue stack, with a conical shaped upper section with a flat top 6), with holes with fly screens 7) in it to provide ventilation for the flue below and prevent insects from entering, attached to the top of the flat top cone section would be a round electricity generating unit 8) with a fittings to allow it to be attached to the turbine 9), a cable 10) to connect the electricity generator to the mains power storage would hang from the underside of the base unit and run down the inside of the chimney/flue stack.

On figure 3, Shows a turbine with a smaller number of curved blades 11) On figure 4, Shows a flat base unit with 4 fly screened ventilation holes 12) On figure 5, Shows a straight turbine blade with a 900 bend on the ends 13) On figure 6, Shows a triangular base unit with three angled legs On figure 7, Shows an example of the proposed invention mounted on chimney stack alongside a traditional "cannon head" chimney pot 14)
