    Batteries are so yesterday. The emerging technology that works seems to be petrol powered motor and a recovery system from when braking coasting that stores energy in capacitor and releases it when needed.
    All of these batteries are heavy and have major fire risk/heat dissappation issues.

    Well they used to keep a big pile of coal up in Huntly that was the equivalent of a full lake for burning when we had dry years in the South!

    Greenies (Under Helen Clark) wouldn't let them burn that so they sold it off overseas, now you just have dry years in the South and dark cold nights in the North!

    Nah that's just halfassery, why have both an electric system and a petrol one when a pure electric can do it all?

    Weight is coming down a lot with these, and a lack of heavy engine requirements means you can get away with batts a lot heavier than petrol anyway. And as for fire risk, you do realise you're comparing it against petrol right?

    True, but throw in a dodgy Shorai ( or some such batt ) and that's where things might get interesting/painful

    Well I'm no expert, but I don't think you need a starter batt with an EV...

    I was actually referring to the lithium batt / petrol combination.

    Seems fair enough to me!

    The LEAF has a 12V battery to run the instruments, lights and such like but this is totally separate from the 24kWh 330V DC Li-Ion battery that moves us down the road. So yes an EV no more needs a 'starter battery' than your Li-Ion Hitachi drill does.

    There are massive stockpiles out near the conveyer head, just grassed over.

    Yeah but baby steps for now and eventually maybe a Tesla, the 'Lightning' of cars

    Impressive power but for ordinary bike (dual-sport?) would need some form of traction control or she would be too bloody much to handle! Very very impressed!

    Bike or car, with electric drive there are no gears, max. torque from zero kmh and very little 'engine' noise. Takes a little getting used to



    This is worth a look, and Monster Tajima is also one of the guests at Evolocity in Christchurch later this month. 670hp and he must have one hell of a battery to drive that hard for just under 10 minutes.

    We will still need a variety of plastic and chemical products in our lives, many needed raw base materials sourced from refined crude oil. So we will still be extracting oil and will be silly not to burn the petrol part in a useful way.

    As for fire risk, petrol needs an ignition source and for the most part is still well contained in a safe manner after a collision.

    Batteries however already preheated from heavy use are primed to self combust if the right shockloading is applied. The problem is this may not occur til sometime after wards when least expected.
    Just imagine high siding your electric bike and the marshals saying right that's your days fun over that thing might burn up...

    We've already seen it with apple devices which are mostly highly regarded in reliability having some units batteries catch fire by themselves.

    Wow!

    I wonder what volt drop and current increase takes place as he keeps the load on as hard as he can (within his driving capability) and there is no re-charge capacity!
