[0001] When cycling, the air drag is as a rule the largest friction loss especially when
it is contrary wind. Precipitation is in nordic climate another problem. If the cycle
road is provided with walls and roof these problems are eleminated. Futhermore in
the tube, which thus is produced the air can be moved by means of the wind. This can
be made in different ways.
[0002] One metod is shown in figure 1.
Figure 2 shows how exess air can give wind energy.
Figure 3 shows how the cycle road pass a bridge and how wind energy is received.
Figure 4 shows how living trees can be supports for blades, which guide the wind into
the road.
Figure 5 shows blades supported by trees.
Figure 6 shows how flaps are put on the blades.
Figure 7 shows how roof are formed by the tree crowns.
[0003] In figure 1 is shown the right file 1 in the tube and that file which normally is
the left file 2, but here is a roof over the right file. At the top there is a roof
3. The upper file has a outlet 4. The right wall of the right file is formed by oblique
blades 5, which form chinks 6 through which the air can pass into the road. The left
wall has oblique blades 7 and chinks 8. Air which goes into the tube is directed forward.
The upper tube has walls, which are formed by blades 9 and chinks 10 and also blades
11 and chinks 12 on the other side. The function is very simple. If the wind is blowing
cross the tubes the blades will direct the wind forward in the tubes. The wind does
not go out through the opposite wall, not even if there is traffic in the tube because
it goes in the same direction.
[0004] The air is driven forward in the tube as long as the wind comes from some side and
also if it turns to fair wind outside. By bending the blades so that the outer part
will be in right angle to the road almost all directions of the wind can give fair
wind inside the tubes. If the tubes are to long the wind speed can be to high. Then
the air will be tapped off as in fig. 2 and through tubes 13 and 14 it goes out and
may pass a turbine 15, which for instance produce electricity in a generator 16.
[0005] If the cycle road pass a bridge the air will be taken into the tube from below as
in fig. 3. Then the precipitation cannot come into the tube. The wind blowes below
the carriageways 1 and 2 and is guided by inlet former (17 or) 18, wind catcher 19
and a valve 20 to go in from below between the carriageways up through oblique blades
21, so that the air goes into the two tubes, but in different directions. The tubes
has right outer walls 22, between wall 23 and roof 3.
[0006] If the bridge is long the air must be let out at uniform distances. At the outlets
wind turbines 15 and generators 16 can be placed. In the example shown the turbines
are situated below the roof top and with horizontal axis in order to be as large as
possible. Before the turbines the cross-section of the tube will be reduced by oblique
wall 24, cealings 25 and oblique blades 26. The outlet for the air 27 is covered by
a roof 28.
[0007] A special road can be made of living trees 30, which are planted in short rows as
in fig. 4. Between the trunks are braded e.g. spinning material 31. This construction
works for fair wind to side wind. With another placing of the trees the blades can
be made as in fig. 5. It works well for all wind directions except for direct front
and fair wind.
[0008] In order to work well for all directions the outer edges of the blades need to be
turnable depending on the wind direction (fig. 6). A large wind vane 40 with a crank
41 and rod 42 move another rod 43 , which is connected to flaps 44 on every or every
second blade. This means that when the flaps are loaded by strong wind the crank will
stand in the dead locks and the vane then manage to keep the flaps in position. For
side wind the position of the flaps are not as critical as for contrary wind. Then
it does not matter if the vane does not manage to keep the flaps exactly correct.
[0009] The roof over the road can sometimes be obtained by pruning the crowns as in fig.
7. When this is not enough the tops and branches can be bent to each other and be
fasten together by ropes.
1. Cycle roads containing files (11, 2), walls and roof where one or both walls consist
of plane or bent blades (5, 7, 9, 11, 21, fig.4, fig. 5, fig. 6), which when they
are hit by the wind direct it in the forward direction or which form an input suck
due to ejecting action from the air, which is driven forward in the arosen tube (channel).
2. Cycle road as in claim 1 where both its forward and back directions has the both
walls made of blades and where the one tube goes over the other (fig. 1).
3. Cycle road as in claim 1 and 2 in which the air is tapped off (13, 14) from the
tubes to the turbines (15), which produce rotation energy, which eventually is converted
to electric energy by a generator (16).
4. Cycle road as in claim 1 in which the wind through inlets (18, 19) and wind driven
valve (20) goes from below in through a between wall made of blades (21), which distribute
the air to two tubes in different directions and in which the other walls (22) and
ceilings are smooth.
5. Cycle road as in claim 4 in which the air is tapped at equidistant points by means
of a part of cealing (25) and cross- section reducing walls (24, 25) to turbines (16).
6. Cycle road as in claim 1 in which the side walls are made of blades supported by
tree trunks (fig.4, fig. 5).
7. Cycle road as in claims 1 and 6 in which all or some of the blades are provided
with flaps (44), which for instance are set by a vane (40).
8. Cycle road as in claim 6 in which the roof is obtained by tree crowns (fig. 7),
which are pruned and bent over the road.
9. Cycle road as in claim 1, which is suited to a general vehicle, which completely
or partly is driven forward by the air.
10. Cycle road as in claim 3 and 5 in which the air from the tubes are driving other
tubes with or without walls made of blades.
