Description
(54) IMPROVEMENTS IN OR RELATING TO ENERGY EXTRACTION
AND UTILISATION APPARATUS
(71) I, JAMES BAXTER, a British subject, of 3, St. Clair House, British Street, London,
E3., do hereby declare the invention, for which
I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to energy extraction and utilisation apparatus for use in connection with a road.
With dwindling resources of fossil fuels, it is important to economise on the use of the fuels, and one way of doing this is to derive energy from other sources.
It is an object of the invention to derive energy from the passage of cars and other vehicles along a road.
According to the present invention there is provided apparatus for extracting energy from vehicular traffic passing along a road including pick-up means set in the road capable of cooperating with a driving wheel of a passing vehicle to be driven by torque applied by the wheel. The torque may be driving or braking torque.
The pick-up means may have an endless flexible belt supported substantially level with the surface of the road and arranged to be capable of being driven by the driving wheel of the passing vehicle when that wheel rests on the belt. The belt itself may be supported on rollers and drive means provided coupled to at least one of the rollers. The belt may be constructed so as to present a plane upper surface when supported on rollers.
The drive means may pass energy derived by the pick-up means to an electricity generator for converting the energy into electricity.
The pick-up means may include a ratchet mechanism effective to prevent a decelerating vehicle from driving the flexible belt, so that the braking performance of a vehicle is not adversely affected by the presence of the pickup means.
The apparatus may be used for powering a roadside utility in which case the pick-up means may be coupled to an electricity generator for converting the energy into electricity for powering the roadside utility.
The roadside utility may be, for example, a street lamp.
In order that the invention be better understood and readily carried into practice, an embodiment thereof will now be described by way of example. Reference will be made to the accompanying drawing in which: Figure 1 shows a diagrammatic cross-section across a road, showing apparatus embodying the present invention;
Figure 2 shows a diagrammatic cross-section of a pick-up of the embodiment of Figure 1 being approached by a passing vehicle; and
Figure 3 shows a diagrammatic plan view of the pick-up means of the embodiment with the flexible belt removed.
Referring to Figure 1 an energy extraction apparatus consists of a pick-up means 1 situated in a trench 3 cut in a road 4. The pick-up means 1 is connected to a drive shaft 7 which passes under the road to a gearbox 8-and electrically generator 9 situated at the roadside.
As shown in Figure 2 the pick-up means 1 includes a flexible endless ribbed belt 2, supported by and engaging four idler rollers 5 and a drive roller 6. The pick-up means may also be provided with a grip to pIevent foreign bodies from interfering with the operation of the pickup means. Drainage for surface water that flows into the trench 3 would be provided but is not shown.
In operation, when the driving wheels 11 of a vehicle 10 move onto the apparatus the force of propulsion i.e. torque developed by the vehicle engine is transmitted via the driving wheels 11 to the flexible belt 2. The belt moves, driving the rollers 5 and 6. The roller 6 drives the drive shaft 7 which in turn drives the electricity generator 9 via the gearbox 8. The drive shaft 7 may be coupled to any of the rollers 5 and 6, and the rollers may be connected to rotate together and thereby provide a more positive drive to the shaft 7.
Referring to Figure 3, each of the idler rollers 5 is coupled to a respective ratchet mechanism 13 which allows rotation of the roller in one direction only. It would be possible to manage with only one ratchet mechanism between all the rollers. This prevents the belt 2 from moving if a vehicle is braking on it. Without the ratchets it would be impossible for a vehicle to stop on the pick-up means in an emergency.
Each of the idler rollers 5 is supported in bearings 14. The drive roller, however, is mounted on an extension of the shaft 7 which is itself mounted in bearings 15. Drive is coupled from the drive roller 6 to the drive shaft 7 by three ratchet mechanisms 16. These allow the drive roller to drive the shaft, and the shaft to continue rotating when the roller is stationary.
There may be more than one pick-up means connected to the drive shaft. Figure 1 shows two pick-up means 1 and la on the same shaft 7.
Various modifications may be made to the embodiment described above. For example, the pick-up means need not have five rollers, nor need the drive be taken from the centre one.
The generator may be provided with a flywheel for keeping up the speed of rotation of the drive shaft between passages of a vehicle over the pick-up means. Electrical storage means such as a storage battery may alternatively or additionally be used.
Whereas the energy extracted by the embodiment described above is converted to electricity, it may alternatively be used to operate roadside pumps; in which case the generator 9 would be replaced by a pump.
Whereas the embodiment described above shows the drive shaft communicating to a roadside gearbox and generator, it may be more convenient particularly in cities and large towns to put them underneath the road.
The apparatus of the embodiment can conveniently be used to power street lamps and other roadside utilities. Figure 1 shows wires 9a connecting the generator 9 to a street lighting cable 9b.
It is convenient to light roads by using energy extracted from passing vehicles especially in tunnels where lighting may only be required when a vehicle is present. Moreover, use of apparatus according to the invention would save on street wiring.
WHAT I CLAIM IS:
1. Apparatus for extracting energy from vehicular traffic passing along a road including pick-up means set in the road capable of cooperating with a driving wheel of a passing vehicle to be driven by torque applied by the wheel.
2. Apparatus according to Claim 1, wherein the pick-up means includes an endless, flexible belt supported substantially level with the surface of the road and passing over at least one roller and drive means coupled to the at least one roller for deriving therefrom energy imparted to the belt by driving wheels of vehicles on the road.
3. Apparatus according to Claim 2 further including an electricity generator coupled to be driven by the drive means.
4. Apparatus according to Claim 3 including a storage battery connected to be charged by the generator.
5. Apparatus according to Claim 2, 3 or 4 wherein the belt is constructed so as to flex in one direction only so that the belt can present a substantially plane upper surface substantially level with the road surface when supported by rollers on its underside.

Claims, wherein the torque is driving torque.
7. Apparatus according to Claim 6, wherein the pick-up means includes a ratchet mechanism effective to prevent a braked wheel from driving it, whereby the braking performance of a vehicle is not significantly impaired by the presence of the pick-up means.
8. Apparatus for extracting energy from vehicular traffic passing along a road substantially as herein described with reference to the accompanying drawings.
9. Apparatus according to any preceding claim further including an electricity generator coupled to the pick-up means for converting the energy into electricity for powering a roadside utility.
