  Nope. The next update will primarily focus on performance improvements and bug fixes (it's still a big update tho). We are aware that permissions are a thing and we'll add the functionality asap. It's a big thing and we want to get the UX right. Please be patient young padawan.

  We have a counter formation table, what i need is more information on each formation, what its best for and not to use against etc, Thanyou
  
  I'm not talking about an EV with an ICE booster or anything Prius-ish like that. How about a compressed air engine or two (a la http://www.engineair.com.au/ ) with compressed air storage tanks on board, backed up by an on board electric motor driven compressor?
  You would still use the petrol station, but would fill up for free at the tyre bay rather than the bowser, and use the charge from a smaller / lighter / cheaper battery bank to extend the range on the air tanks with a compressor that requires no fancy / expensive control system.
  I would expect there would be enough torque from the air engine to keep all the standard automotive systems - power steering, aircon etc. running just fine.
  This isn't a considered plan, just a spontaneous mind meld of various technologies I've been watching for a while that seem to look good together. My gut feel is that a working system would come in well below the price tag attached to most of the pure EV options out there. I don't believe Angelo Di Pietro has his air engine on the market for sale yet, but has working prototypes and is looking for joint venture involvement. He didn't reply when I e-mailed to ask if I could buy one of his engines to try out, but perhaps if a larger group was interested he might look at getting involved. There are other air engines out there of course - but this one is locally grown and seems to me to have huge potential.
  4 or 5 years ago, homepower did a piece on storing energy in the form of compressed air. they calculated that a 1.5m tall 50cm wide cylinder raised to 3000PSI stored 0.5kwh.
  he wont want people to buy his engine privately cos there will be loads of people out there trying to build a copy and beat him to certain markets.
  i have previously looked into the engine, its definately interesting and will "refuel" in seconds etc. i imagine though to produce 60-ish hp (enough to drive a car down the freeway nicely) it will require a huge amount of air. see how fast a die grinder or other air tool will drain a tank, and think about how little that is in comparison.
  the engine definately finds good place in the fruit market buggies etc. where replacing batteries every 2 years is an un-nessecary expense and lower weight is a bonus, but the size of the tanks needed for long distance travel are too extreme under any level of air technology. even with battery assist, i doubt a compressor will be able to regenerate lost air fast enough for long enough.
  in saying that, i have no calculations to back my statements, just theoretical comparisons. i hope someone prooves me wrong as that is the beauty of engineering!
  also another note, considering the simple laws of physics you will have two stores of energy on the vehicle, batteries and air tanks. you will also have two energy conversion devices (air motor and generator). each device will use some of the transfered energy, and one storage device will be more effective than the other. wouldnt it be better to choose the better storage device to hold more energy and couple it with one efficient conversion device to save on wasted conversion energy?
  Lowndsy, You are thinking well, and answered your own question in the last paragraph of that post. As Rob Mason says, just put a few more batteries in !
  With my rudimentary physics, I would have estimated that in Matt's example above that the energy input to the compressing system would have been 1.5kWh for the 0.5kWh energy stored. This is mostly related to the law PVT is a constant (Pressure x volume x temperature, was it Boyle ?).
  Assuming a 60% mechanical efficiency from power source to compressing point, but then the temperature rise and subsequent heat loss (energy loss) as the air is compressed and the pressure rises in the storage container. This heat loss is total loss and is likely to be 50% or more so we are down to 30% efficiency. Hey, don't take my word for it, go google.
  There is nothing wrong with air motors. Fantastic power to weight, craftsmanship in mechanical engineering. But very low efficiency.
  To suggest refill in seconds caps off Matt's scam thought. I'll be standing a long way away if you try to fill a diving bottle to 5MPa in seconds. Once again, PVT is a constant. Note the bottles are normally stood in a water tank to keep them cool, and filled in 10 minutes or more ! (all 0.5kWh)
  Remember here that an EV (conversion ?) requires at least 20kWh to go 100km or so. I'm just not certain where to mount the 40 diving bottles and how much it would cost to fill them. Definitely not from 600kPa at the local service station ! OOps, that's assuming 100% eff. from the air bottle to the back wheels... try 30%. No problem I need 120 diving bottles now ! 1.5kWh x 120 x 15c = $27 to fill (electricity cost alone). I just have to find somewhere for 2 tonne of bottles. Ok, unkind, one big bottle... and I could open the tap on the back and sing an Elton John song.
  Using single gasses rather than a mixture such as air can improve efficiency if the gas undergoes a state change from gas to liquid as part of the process. Refrigeration (in particluar, reverse cycle) is an example of this. This is of course a closed system and relies on the latent heat of vapourisation to achieve energy transfer. Sorry I mentioned it. Nothing to do with EVs (except for reverse cycle airconditioning for heating and cooling).
  There is nothing as clean and pure and zero emission and efficient and quiet and controllable and low maintenance and renewable and..... as electricity ! It is very storable and transferable, with storable being the area where most development is required. i.e. batteries or may favourite - ultra caps.
