Yesterday I talked with Mika about Rubber tracks and all kind of transmission things. Mostly there was that idea of why things are going towards direction where they are. It is starting to clear out why for example is seems that there is lot interest to electric transmission.
Like show here.

Firstly, as for example Rubber tracks are more silent and fuel efficient. It is same with hybrid electrical drive systems. Those are not only in APC technology but in casual work machines of real life as well. This has been hot discussion on forest machines for a long time.
Basically idea is something like this. There is normal engine thought usually even smaller. That will power generator that provides electric power from electric motors that alone are transmission. I mean from those motors power is directly going to brakes and to final gear or directly to tracks / wheels.
There is many advantages in this.
One is that while braking, or going downwards without power these motors actually download batteries.
More over, placing engine from where power to motor / batteries come is free, and engine can be smaller.
electric motors can be directly at the place where needed and can be individually adjusted! This is something that so far has not bee working well with hydraulic systems! Also there is very small power lose when done like this!
Problem so far with electric motors and systems has been motors itself as far as I know. But as in forestry those have been seen more and more frequently. last when I have seen machine running with electric motors it was quite small. But those sizes have been coming bigger. So. I assume this might have some troubles with strength at the first, but other than that this system is very good and reliable. Less moving parts, and should be easy to maintenance as well.

Not to forget the fact that with transmission controlled electronically things get more simple and easy. Less parts, more simplicity. And more over. There will come time when Computer will be driving tanks instead of driver. It is far more easy to make happen on this kind of transmission than in normal one where you would need servos and all kind of stuff and extra parts. in system like this, it is all about controlling electricity that computers already do. So systems will be more precise and remote use will come even more likely to happen than it is currently.

Trials for unmanned vehicles are about to start in a big way. This is the future in some situations but would you get onto a plane with no pilot?
-
Probably not into plane. :D At least if I can't do anything by myself in case of trouble in the air.
But yeah. Some cars already have been tested to have automatic driving. So... I guess it will be future.
