cool! im an applied physics student myself...
-what about studying the combustion of the engine and reseraching on new methods of fluid motion such that it can increase effeciency of a nitro engine. in other words, better porting..
-electronically adjustable shock damping
-what about a cooling system for nitro so that we can lean our engines a bit
-controlled nuclear fussion combustion engine?? ( probobly 100yrs from now or less)
-a new kind of differential that can be adjusted easily that can be used for nitro and has the characteristics of an oil differential, this should allow powerful engines we have today to work with ease ( i hate getting my hands full of oil with i change the diff oil in my rrr)
-a new kind of transmission system?! better than shaft and belts...
(a good start might be a car whose clutch gears are transferring energy to two spur gears. both spur gears then transfer power to front and rear wheels. dunno if that's any good... )
sorry, cant think of anything cool.. my mind is filled with wave equations right now.. hehehehe
