Tesla
Perhaps, when you see this title, you will immediately judge me that I prefer Tesla to Edison. Well, I’m not going to talk about it further, because people have their own preference. You might question, something must have triggered me to entitle this post with “Tesla”, and you might also have the answer already. Yeah, that trending on youtube, that everybody is amazed with Tesla. I’m not the exception of that one. And of course, (one of) my best friend(s) who mentioned automotive stuffs that made me resurrected.
TBH, when the prototype was launched for the first time at 2012, I was like, well, really? I kind of despised it. Are you sure it’s gonna work? But, when now they actually test it on the road, I am kind of mesmerized. That-is-super-cool, you know. Realizing the fact that I barely know things about Tesla, I’m reluctant to admit that I was an electrical engineer graduate. But I have a good excuse that I didn’t take the power engineering major (like @intuitivetruthseeker :P). And FYI, for that amazing lithium-ion battery, @arlavinda2 is the expert for that field.
Nevertheless, I’m still so obsessed to explain briefly about (Nikola) Tesla’s creation. So fantastic that it’s ageless, although now it’s been around 100 years. We call it: induction motor. More specifically, AC (alternating current) commutator-free induction motor. While the standard vehicle’s machine works with internal combustion, Tesla’s vehicle works with induction motor. Sounds so eco-friendly, uh? What actually happens there? First, consider the massive numbers of batteries in the floor of the car, they flow unidirectional current (DC) to the induction motor. Because actually the motor needs the AC one, inverter is needed to make it alternate. One benefit of the AC motor is that we can control frequency of the current in such a way that it can also control the speed of the motor. And we can also control the amplitude of the current, thus it can also control the motor power output. Motor power output is useful to control the gearbox that will move the drive wheels. That was all the thing that I can say here, because I won’t comment anything about the torque thingy. :P
The most significant impact is on its acceleration. For Tesla S P100D (in ludicrous mode), within 2.28 sec, it can reach 100 km/h from 0 km/h. As comparison, Porsche 918 Spyder (its biggest competitor, probably the fastest in the world) is 2.2 sec for reaching the same speed. Incredible, right? For those who love super car, it’s definitely worth it (except for the price :P).
Conclusion: if I were a billionaire, I’d definitely purchase one. :P
Trivia: I texted @deamahfudz the words that I got from Wikipedia. They were: “Tesla never married; explaining that his chastity was very helpful to his scientific abilities. He once said in earlier years that he felt he could never be worthy enough for a woman, considering women superior in every way. His opinion had started to sway in later years when he felt that women were trying to outdo men and make themselves more dominant.” I was like: “Teslaaa, you BROKE our heart so baaad.” And she replied: “Because he hadn’t met you yet.” :)) I wish I could have changed his mind (and-that-scientific-ability-orientation). :P
