Abstract

A vehicle induced wind harvesting vertical axis turbine comprises a rotor 6 in a horizontal plane which includes twin part fan blades 7 with upper portions 9 to be driven by the weather wind and lower parts to be driven by the traffic flow wind. A generator is driven by a spindle that the rotor is mounted upon. There may be shorter secondary blades mounted above the main blades which may be supported by wires having further blades on the cables. The turbine may be suspended above the road central reservation or margin and span lanes in both directions. Wind guidance fins 1,2,3,4 may be installed on the road edges and central barrier 5. Further fins may be mounted on vehicles to help drive the turbine.

DUAL ECO POWER HORIZONTAL TURBINE

This invention relates to a dual eco power horizontal turbine.

When the traffic goes past you can notice how far travels the paper that lies on and beside the motorway. Also if you drop a balloon off a motorway bridge you can see how far it travels.

This idea uses the wind power created by the motorway traffic and so use the fuel petrol and diesel for two purposes. The traffic on both directions of the motorway can drive the horizontal fan turbine.

Whereas this idea uses the wind power created by the traffic and also the weather wind, what is useful as well is that the high lorries are travelling in the outside lane of the motorway, so as the wind created by them is directed to the outer circumference of the wind turbine. This type of turbine doesn't just have to rely on a windy day to generate power.

A dual eco power horizontal turbine would best be installed in a hill cut through as on M40 at tame or A3M buster. Or in a valley position as in these positions the weather wind can only blow in two directions as the flow of traffic creates the same.

This horizontal wind turbine could be installed in open motorways, as it would still turn this type of fan with the help of the traffic flow. This horizontal fan would be installed over the motorway at the right height above the traffic flow. It would then be propelled by the wind created by traffic.

The fan blades would be at the correct angle to catch the wind. This fan would catch the wind power in both traffic directions for turning in a clockwise direction in right hand drive countries.

It would need large wind direction fins each side of the motorway to maximise traffic wind power.

Also by crash barrier as plan. Large lorries with wind directions fins would help. A horizontal fan blade wind turbine would be much more efficient and would not damage the country side landscape.

Horizontal wind turbine propelled by wind created from lorries and traffic. And by the wind direction if situated in a valley as the wind can only blow up or down the motorway. Also the large lorries develop the wind to turn the outer edge of the large fan blades. There could be fins fitted at the top of lorries to help push the fan blades round.

The invention will now be described solely by way of example and with reference to the accompanying drawings in which: Drawing I and 2 shows a horizontal wind turbine being driven by traffic flow wind and weather wind in a clockwise direction by fan blades which are above and below by the turbine wheel design.

Drawing 3 figure 1 and drawing 4 figure 1 show double blade. Figure 2 shows eco friendly air fin fitted at the top of a lorry. Figure 3 shows test turbine fan attached to the bridge.

Drawing 5 figure 1 and 6 figure 1 shows spindle, wind turbine and supports. Figure 2 shows longer and shorter blades and spindle.

In drawing 1 vertical spindle 12 is attached to the wind turbine 6 with supports 13 to turbine double fan blades 7, 8 which are above to take the long blades. These fan blades are of special design so as the top blades 9 would catch the weather wind and the bottom blades 10 would catch the traffic flow wind. The generator 11 is at the centre of the turbine construction surrounding the spindle 12 which houses the bearings.

The traffic flow which helps as for example traffic going North rotates the fan blades in the same direction as the traffic travelling South to catch the wind flow to the blades. To maximise the wind power would best to install wind direction fins 1, 2, 3, 4. The crash barrier 5 would be there each side of the support spindle in the centre reservation of the motorway.

Drawing 3 figure 1 shows double blade which has got the top blade for weather wind 1 and the under blade for traffic wind 2. The design of these fan blades would be best made by experts to be most efficient.

In drawing 3 figure 2 eco friendly air fin 1 is fitted at the top of a lorry to help push the fan blades round Drawing 3 figure 3 shows example how to test fan 1 to be fitted horizontally at the edge of the bridge 2 at the centre of the motorway.

This idea could be tested with a small fan on a bracket hanging over the side of the motorway bridge at bridge underneath level above centre crash barrier or on its own post. It would catch both fast lanes. The fan blades need to be installed about 1 meter above normal bridge height.

Traffic in the fast lanes rotate the fan. Travelling in both directions the large fan will be the complete width of the motorway.

In drawing 5 figure 1 the plan shows side view of the large fan turbine 1, fan blade supports 2, support spindle 3 and bearings 4 to allow rotation of turbine on support spindle 3. Also generator 5 which generates power. All fan blades are shaped to catch wind to drive in clockwise direction. Extra wind blades 7 are shorter in length no need to supports. Bearings 4 are to enable turbine to rotate. Supports 2 which support large fan blades I contain extra weather wind 6 to drive the large fan in the clockwise direction. Pillar 8 is the large pillar which supports bearings 4 and spindle 3.

Drawing 5 figure 2 shows top view of the wind turbine. Longer blades 1 and shorter blades 2 allow rotation of the dual eco power horizontal turbine on the support spindle 3. Claim
