It is probable that I am violating some fundamental principles in making this suggestion.
I didn't have a good grasp of the technical challenges back in the 70's when I first became aware of this possibility and I still don't. That is why I am here. I know there are folks here that know this stuff.
Wheeled Vehicles:
I wonder if it would be possible to charge an electric vehicle by induction while it is moving. Where one or more lanes in each direction of the Interstate and other major roads have a low voltage induction cable just below the surface. This cable would be used to supply a rate changing magnetic field used to induce power in the charging circuit of the vehicle without physical contacts. In widespread application, this would extend the range of an electric vehicle to infinite value where the vehicle operates on battery stored power when operating on short trips (>100 miles) off the grid. The circuit would be part of the commercial power grid with the power metered at the vehicle.
Could the acceptance of the charging circuit be increased by super cooling the inductor?
What are we talking in terms of field change rates required to induce usable power through a distance of let's say - .05 meters?
Remember we could pull peak power demand of the vehicle off the vehicle storage device and allow charging at a near constant rate.
In my simplistic understanding the grid voltage would be stepped down before entering the transportation circuit and then stepped up again before being fed back into the commercial load grid. The purpose for this is to increase the ampere value (field) of the charging grid.
In widespread usage the instantaneous demand on the grid would vary quite slowly as vehicles moved on and off the grid.
The down side; because we use so much energy in transportation, it would require a very dramatic increase in power production capacity. Hopefully this increased demand for electrical energy could be somewhat offset with solar and wind power using hydro-storage technologies for meeting peak demand periods.
Would it be possible to reduce the carbon footprint of current transportation technologies in this way?
Electrical power production and distribution is notoriously low in efficiency, but because this technology may lend itself well to power averaging and regenerative braking; it may not be that crazy of an idea.
Airplanes:
I believe we should be flying 1/2 inch off of an enclosed guide-way instead of at 30000 feet. This would not only allow us to radically increase efficiency; but allow us to use electrical power instead of petroleum based fuels. Could this be accomplished by using electro-fan and aerodynamic lift in an enclosed non-evacuated guide-way. This being the first incremental step with the final evolution being the use of electromagnetic lift and electromagnetic propulsion in evacuated guide-ways?
So what do you folks think? I'm here to learn, don't worry about hurting my feelings or forcing me to a text book. I may be getting old but I am still on the learning curve.
