BACKGROUND OF THE INVENTION
A. Technical Field
The present invention generally relates to a power generating apparatus. Specifically, the present invention relates to a power generating apparatus configured to generate electrical current from moving objects, for example, vehicles.
B. Description of Related Art
Energy demand across the world has increased rapidly in recent decades with economic growth and the spread of industrialization in developing countries. Currently, there are many different types of electric power generating plants operating to produce power from renewable and non-renewable energy sources to meet the world's energy needs. Power generation broadly comes from sources such as coal, nuclear, natural gas, hydroelectric, wind, oil, solar, geothermal sources, etc. Power generation from oil, coal, and similar sources typically leads to pollution and is thought to contribute to global warming. Power generation from nuclear raises safety and security concerns.
Additionally, much of the electricity generated from more recently installed renewable energy sources has been more costly than non-renewable resources and has its own unintended environmental consequences. Some examples of unintended environmental consequences are that wind turbines kill large numbers of birds every year; ground based solar power systems consume large swaths of land; and solar panels are manufactured with hazardous materials. Thus, there is a significant need to generate electrical power from other cost-effective sources to meet the world's energy needs without causing pollution or other unintended environmental consequences.
A prior art, U.S. Pat. No. 7,164,211 of Tafoya et al., discloses a system and method for generating electric current from automobiles. The system includes power pods having multiple permanent magnets or coils of wire. The power pods could be installed within the heavily trafficked roadway surfaces and railroad beds. When vehicles pass over the power pods, the permanent magnets or coils of wire create a current routed for productive use. But one of the numerous commercial limitations of this system is the enormous costs that would be incurred by digging up existing roadway surfaces to embed power pods into roadways, as well as ongoing costs of re-excavating sections of roadways when inevitable maintenance is required.
Another prior art, U.S. Pat. No. 10,135,376 of Brier et al., discloses a regenerative energy system to produce energy from moving vehicles using magnetic induction. The system consists of a ground transportation vehicle having one or more magnetic elements attached to the underside of the vehicle, one or more magnetic coil assembly consisting of a core and magnetic coil installed in an adjacent and spaced out manner along a travel route. The vehicles are accordingly operable to accelerate and decelerate when the vehicles are proximate to a magnetic coil assembly for generating electrical current. The artwork clearly shows the vehicle traveling on railroad tracks. This system also looks to be highly impractical for generating electrical power.
Accordingly, there is a need for a power generating apparatus to efficiently generate electrical power from moving objects, for example vehicles, with negligible environmental impact and negligible impact to existing vehicle motion. There is also a need for a power generating apparatus simply installed on the surfaces, for example, highways and roadways without digging up the surfaces. There is also a need for a power generating apparatus to prevent snow and ice accumulation on the surfaces where it is placed in regions where snow and ice occur; and as a result, the apparatus also significantly reduces damages to roadways, highways, and bridges that would otherwise be damaged by snow and ice removal via snow plows, road salts, and other de-icing chemicals. There is also a need for a power generating apparatus to protect the surface or layer on which it is placed. This will extend the life span of surfaces, for example, highways; which means their replacement costs are significantly deferred. An additional benefit of this invention is that any pre-damaged surfaces, such as but not limited to; surfaces with pot holes and/or significant cracks, the vehicles or objects will no longer encounter the damaged surfaces but will instead move along a level solid surface and thus encounter a much smoother and safer experience.
SUMMARY OF THE INVENTION

In one embodiment, one or more devices are affixed to a bottom portion of a vehicle. In another embodiment, the devices are affixed to tire portions of the vehicle. In some embodiments, the devices are affixed to tire rims of the vehicle. In one embodiment, the devices are made of magnetic elements.

In one embodiment, the plurality of windings 104 of the strips 102 positioned in the platform 100 should be perpendicular or close to perpendicular, to the magnetic fields passing overhead or nearby or through, in order to generate electric current in the plurality of windings 104.

Referring to FIG. 12, the platforms 100 are positioned on the surface, for example, but not limited to, roadways and highways. In an exemplary embodiment, the platform 100 could cover the entire width of a roadway. In regions where snow and/or ice occur, the platform 100 could melt the ice and/or snow to prevent ice and/or snow accumulation on the platform 100 and the roadway. In another embodiment, the strips 102 (shown in FIG. 1) are positioned at desired or selected areas inside the platforms 100. The position of the strips 102 (shown in FIG. 1) will depend on the standardized location of the devices/magnetic device on the objects they are affixed to.
The platform 100 efficiently generates electrical power from moving vehicles and with negligible environment impact and negligible impact to existing vehicle motion. It is simply installed on the surfaces, for example, highways and roadways. The platform 100 is a cost effective and simple power generating apparatus for generating and supplying electricity. In cold weather regions the platform 100 could contain an additional feature to prevent snow and ice from accumulating on the platforms and on the surfaces; that will reduce the damage to roadways, highways, bridges, etc. and the environment that is currently caused by snow and ice removal by snow plows, road salts, and/or de-icing chemicals.
The power generating apparatus/platform 100 protects the surface or layer, for example, highways, on which it is placed. This will extend the life span of surfaces, for example, highways; which means their replacement costs are significantly deferred. An additional benefit of this invention is that any pre-damaged surfaces, such as but not limited to, surfaces with pot holes and/or significant cracks, vehicles or objects will no longer encounter the damaged surfaces but will instead move along a level solid surface and thus encounter a much smoother and safer experience.
