I still think thats an option for trucks and trains ... It isn't reasonable to move thousands of pounds from coast to coast just so you have transportaion at the other end. High speed rail ... (Which I doubt will happen because of the costs) works in the rest of the world. Air freight works in this country ... but airlines are suffering ... so I would like to see an alternative to move fruits and vegatables almost overnight from coast to coast. tactless
Why not do it right with one of the wireless methods like inductive charging?
You don't need the overhead wires and a mast to be in contact with the wire. Along with providing the power from inductive charging, you can have self-driving vehicles with each vehicle on the "network". You can have lanes for through traffic running at 100MPH and other lanes at reduced speed for exits and entrances. Program in your destination or hit a button for "bathroom" or "rest area" or a restaurant and automatically have your route implemented. Sensors can allow for higher density at high speeds with few accidents.
It is actually quite simple... wonder how many years it will take before you can go coast to coast in a self-drive vehicle.
not exactly ... street trollys with overhead wires and electric rail lines have been in use for a century. I believe most if not all the high speed trains in Europe are electric. So energy density is not the only criteria in moving people ... For insance jet planes have to be sized for the load ... you can't make a profit using a 747 from Columbus GA to Omaha ... reguardless of the energy density of the fuel. So there is a lot to the equation ... Electric trains and trollys and busses may work because you move lots of people. tactless
"you can't make a profit using a 747 from Columbus GA to Omaha ... reguardless of the energy density of the fuel."
A battery powered passenger airplane would not even get off the ground! :)
A few more facts: The current cost for Li-on batteries is about $800 per KWh (kilo-watt hour). A four or five passenger Electric vehicle needs about 350 watt hours of energy to travel one mile. Thus, an EV with a 300 mile range would need a 100 Kwh battery which would cost about $80,000.
