    Thinking outside of the bus? lol

    Norton, erixx and D007 say thanks.

    If more people would start thinking like this. Goodbye energy crisis.

    I don't know if I'd go that far... but it certainly is brilliant.

    Making sure innovation takes a long time to become mainstream to maintain profit from the old is the present!

    think of how much energy is wasted when there are no buses... it can be weight activated.... but this idea needs ab it more tweaking.

    In Volvos version (which is directly connected to the road, sort of like Hot Wheels et al) the lines are only live when there are vehicles there. How it works exactly I don't know. But yeah that is probably a requisite.

    :confused:

    If theirs nothing to receive the charge than the charge isn't going to move anywhere. It's not like this thing is shooting electricity into the air when theirs no buses.

    I think it senses when the proper vehicle is present. If it was on all the time, there indeed would be wasted electricity if electrons are moving through the underground conductors.

    it needs to make a circuit for electricity to flow.

    no bus = no circuit.

    its like saying power outlets waste electricity with nothing plugged in.

    High tension powerlines basically buried under ground is all this is. This could be useful in heavy congested areas but useless anywhere else. Its a novel idea but nothing that will change the world or even mass transit.

    Technically the line is the circuit. Not the bus. The bus is just leaching off the byproduct of a high voltage line (underground circuit).

    Mussels, it's induction, there's not a plug in the middle of the road!

    Power= current X voltage (P=IV) IF no current is being drawn (inductive or otherwise) then the power line uses no power. There are losses due to resistance in the wire but these are generally only a few %

    This is very much similar to how a water tower maintains pressure at it's base. If no water is being drawn through the water line then there is no loss in pressure.

    When a car or other vehicle passes through the feild, it will induce current and there will be power loss. If you have current passing through a conductor there is power use (unless you're talking super-conductors), but as you say, not much. They may use constant current regulators, I don't know

    Article states this:

    That would imply it shuts off a segment when it's not inducing a current into the intended target.

    Also along main roads. Obviously not for rural areas, but along parts of the swedish E4 for instance it would be ideal.

    And the new part is obviously not burying cables, it's how the power is utilized, and the fact that they seem to believe it's a viable alternative. The biggest threat is probably the self driving cars they say we'll have.

    BTW, from the original source (under News):

    Kinda similar, in a crude analogy, to those inductive charging mats that can charge your cell phone but you can't make a grilled cheese sandwich on one.

    Mmmm!!! grilled cheese.... with tomato and bacon!!! :D
    Ahhzz, Sasqui and manofthem say thanks.

    I wonder what this does to the testicles, riding a couple feet off of an electrical grid? :D Kinda serious question.. :p

    But then we won't be able to sell our enormous supply overseas only to be sold back to us at a huge increase?! Really though, it would be great to be off of it.. for everyone not profiting off of it anyways.

    HAHHA makes men think of sex even more often.., i was thinking what if the cables become damaged is there a chance of people getting electrocuted lol.


    Although it be kinda cool seeing everyone's hair stand on end

    OK, this us great and all, but how is the efficiency? Last I saw, induction over any distance more than a few mm is extremely inefficient.

    Not exactly an answer to the energy crisis if it wastes a crap load of energy.

    The solution of having quick chargers positioned strategically along the route the charge the bus when it is stopped to pick up/drop off passengers seems like a better solution.

    Now we just need to wait for the 80Plus Platinum rated induction system. :roll:

    i reject your reality and substitute something logical sounding.
