Can Cars Run Off of Solar strength?

Because of a general without of effective public transport, it is necessary for most of us to rely on private transport and own a car. It is best to make sure this private transport is as environmentally friendly as possible, which leads us to ask whether a car can be run on solar strength.

The amount of energy from the sun that reaches the surface of the earth each day is staggering. There is easily enough energy there to strength all human industry and transport several times over. A great deal of this energy is reflected back into space from the surface as light or radiated into space as infra-red energy, which is another name for heat.

The great advantage of solar panels is that they generate electricity from sunlight that is already falling on the surface of the earth. Had that energy not been converted into electricity in the panel, it would have been absorbed by the earth to be later released as heat, been reflected into space, or been used by a plant to make sugars. The electricity from the panel can be transported and used in other places. When used, the energy in the electricity is ultimately released as heat. This method that a solar panel is effectively converting sunlight into heat, but allowing that conversion to do some work which results in the heat moving to a different location.

This compares favorably with using fossil fuels as an energy source. Because these fuels come from long buried supplies, the heat they add to the air when burned is additional to what would otherwise be there. This method that there is a net increase in energy in the air, and it is this that causes concern regarding the issue of climate change.

This makes it clear that being able to use sunlight to strength our vehicles is a desirable option. But is this a realistic option? The fact is that this is already being done. Owners of electric cars are using mains supply electricity instead of petroleum to charge the batteries which strength their vehicles. All that needs to be additional to this scenario is to acquire the electricity from a replaceable source such as a domestic solar installation or a solar strength plant and one can effectively be driving on sunshine.
