Hi everyone, A friend of mine introduced me to one of her friends who was claiming that he is able to go up to 95km/hr with an electric vehicle that he designed from scratch (which is not extraordinary).First I thought it's just one of those electric vehicles that he wanted to build but sooner I realized that this is something bigger. He said his vehicle has 500km driving range with 4 standart car accumulators (12V) connected in serial as power source. At first glance I said this is simply not possible because I had been in a Tesla and I know the very specs of it and I made a reasonable initial assumption that he can't come up with a better product than those engineers did because this guy has no education in ANY topic, his academic career ended after elementary school when he was 8 or so (seriously). Before saying anything he wanted me to test his vehicle. He started the engine and told me to do anything I want. Torque it exerted was in the range of the classes of motors he is using (550 W x 4 engines) but (as a car fan and a good driver) acceleration felt very much different than any other vehicle I had been in. I tested his vehicle and it is VERY good both in acceleration also in climbing hills compared to engine it is using. I entered to a 30 degree 10km uphill road at 90km/hr and completed the road at 70km/hr. All these can be done with precise engineering, nothing wrong till here (relative to the driver at that moment - which is me). Interesting this is that after 110-115kms of tripping I stopped at his workshop to measure battery levels which were suprisingly still around %60.This is something I couldn't explain. Even before doing any calculations, I knew that the moves I made while testing his prototype had to draw way too much than %40 of those batteries, in fact after 80kms machine started amazing me. I had driving experience with lots of cars (some were even 400hp+) driving this vehicle feels very very solid and acceleration characteristic is unique I suppose, again it is different but not in a way that I can express so I asked him what's the trick and he replied "I honestly don't know". This guy has no background in anything, he just makes his living repairing cars. For a yettosecond I considered if there could exist any possibility that -this guy- exploited some undiscovered or forgotten phenomenon in nature that could make transportation easier (I have tendency to believe) because what was standing front of me didn't fit any movement system I was aware of. What I can tell from my observations is that motion is not created turning the wheels by exerting force on them - like current cars in market ; instead changing the cars center of gravity, the body is forced to move forward so energy is used to change center of gravity and this internal change results origination of motion in wheels. Wheels are mostly used for directioning, no constant electrical force exerted on them. I realized it could be a 4 wheel interpreted version of segway's around. I decided to make a simple test and loaded the car with 800kgs of people (10ppl) also note that vehicle weights around 1100kg =3D 1900kg. I was able to turn the wheel (parallel to ground in +x direction) with my index finger and vehicle started moving like it has no friction and 10 people on it. When vehicle moves lets say 10cm, from my understanding point of view, I move 2 tons with a push of my finger. The energy I get from this system is way much bigger than the energy I applied from my observations. In other words, efficiency is observed to be greater than 1. I know that this simply violates conservation of energy thus I wanted to share with you so if one can spot the missing piece and explain how come this is possible.
