Abstract

The apparatus is for extending the range of battery operated electric vehicles by supporting the level of charge held in the batteries for a longer period thereby reducing the number of recharges from the mains supply. The apparatus comprises a duct 10 which is constructed in three parts: air or fluid intake 11, rear section 12, both being fixed to the vehicle, and a rotatable central section 13 fitted with turbine blades 14 and connected to an alternator 15 via a belt 16. Ducts can be fitted in parallel. <IMAGE>

Description

Electricity Generating Apparatus This invention relates to electricity generating apparatus and more particularly but not exclusively to such apparatus when incorporated in a vehicle.
According to a first aspect of the present invention there is provided electricity generating apparatus comprising an elongate duct having at least two parts, one of which is rotatable relative to the other, the rotatable part having internal blades which cause said one part to rotate relative to the other part when fluid passes through the elongate duct, and an electric generator for generating electricity in response to rotation of said one part.
Preferably, the duct has three parts and the rotatable part is disposed intermediate two stationary parts. In this case, preferably, the in use upstream end of the rotatable part is mounted for rotation about the end of its adjacent stationary part and the in use downstream end of the rotatable part is rotatable within the end of its adjacent stationary part.
According to a second aspect of the invention, there is provided a vehicle incorporating electricity generating apparatus according to the first aspect of the invention.
Preferably, the elongate duct extends from front to rear of the vehicle.
Preferably, at least the in use upstream end portion of the duct is convergent in a downstream direction.
Preferably, the vehicle is powered by electric batteries and the electricity generating apparatus feeds power into the batteries.
The invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a side view of one embodiment of electricity generating apparatus according to the present invention, Figure 2 is a front view of the rotatable part of the duct and also shows the alternator, Figure 3 is a side view showing part of the electricity generating apparatus of Figure 1 incorporated in a road vehicle, Figure 4 is a plan view showing part of the electricity generating apparatus of Figure 1 incorporated in a road vehicle, and Figure 5 is a front view of the vehicle showing the air intakes.
Referring firstly to Figures 1 and 2 of the drawings, the electricity generating apparatus shown therein comprises an elongate duct 10 having two stationary parts 11 and 12 and a rotatable part 13 disposed between the parts 11 and 12.
Fluid is funnelled into the duct 10 through a convergent mouth at the leading (or upstream) end of the part 11 and flows through the part 13 and then through the part 12.
The leading (or upstream) end of the part 13 is mounted for rotation about the trailing (or downstream) end of the part 11 and the trailing (or downstreamj end of the part 13 is mounted for rotation within the leading (or upstream) end of the part 12.
This allows fluid to flow through the duct 10 with the minimum of interruption. A low frictional bearing is provided between the rotatable part 13 and each of the stationary parts 11 and 12.
The rotatable part 13 has internal blades 14 which are preferably shaped similarly to the turbine blades of jet engines. Thus, as fluid (whether it be a gas, e.g. air, or a liquid) flows through the duct, the part 13 rotates relative to the parts 11 and 12.
The part 13 is connected to an electrical generator, e.g. an alternator 15, such as by a belt drive 16. Alternatively, the rotatable part 13 could form part of a rotor of the generator.
Figures 3 to 5 show two ducts 10 mounted side by side in a road vehicle, each duct extending from front to rear of the vehicle and typically beneath the passenger compartment. The rotatable parts 13 of the two ducts 10 are connected to the single alternator 15 via respective electromagnetic clutches 17.
As will be seen particularly from Figure 5, the intake ends of the ducts 10 are quite large in order to funnel as much air as possible into the ducts 10.
The road vehicle is preferably electrically powered by batteries and power generated by the alternator is fed into the batteries.
A cutout may be provided to disengage the rotatable parts 13 from the alternator 15 when the batteries are at optimum charge thereby allowing the rotatable parts 13 to free wheel.
An ammeter connected into the circuit can provide a driver with a visual check on the charge levels of the batteries.
The provision of the ducts 10 alone should make the vehicle more efficient by reducing the drag on the front of the vehicle.
The ducts 10 could be made of lightweight material to minimise additional weight.
The electricity generating apparatus described above could also be incorporated in electric trains and in liquid pipelines, such as high pressure mains.
