Hi, everyone and welcome back to Geek Time, 欢迎回来【极客时间】. Hi, Brad.


Hi, Lulu, hello, everyone.


Long time no speaky. How's life treating you in Japan?


Pretty good. Can't complain about anything.


I heard last time we were talking you really got into car racing.


I've been into car racing for a while, but I actually entered my first race last month.


Wow, how did you do?


Did fairly good. I wasn't the fastest on there, but my car is pretty much stock except for I got a little bit better tires.


在赛车的语境中,"stock" 指的是车辆几乎保持原厂状态,没有经过大量的改装或升级。


Okay. How many cars do you have right now?


Currently I have five cars, one in the States and four in Japan.


You have four cars in Japan. Wow. It sounds like you're pretty serious about it. I mean, I assume they're all gas cars.


They are indeed, they are all gas cars.


So I thought today let's talk about EV. LOL.


Okay.


我们今天来聊一下电动车 EV, short for electric vehicle, right?


Right.


So to talk about EV,  Brad, you obviously know cars a lot more than I do. So let's talk about the different engines. So you have gas or, you say gas, British people say petrol. That's the same thing, gas, gas station, petrol station same thing.


Same thing, yeah. Gas or petrol is pretty much the way most cars are. In some places hybrids or electric vehicles are becoming more popular. Hybrid is kind of like in between where you don't have to charge the car, you use gas sometimes. And when you're going so fast, you use the electric power to drive the car. And so it's kind of an in between.


Okay. Can you give us... I know, I mean, you're basically from an engineering background, can you give us a little bit of a very, very like a for dummy version of how does it work with gas powered or petrol powered cars.  How does the engine work?


Basically, you have a cylinder and within that cylinder, you have a little bit of gas and air, and then you ignite it, which causes an explosion, which causes a piston to move downwards. And that creates a rotational movement,  basically kind of...


Drives the cars forward.


this rotational movement which causes the car to move.


I see. And just now you also mentioned hybrid,  we said gas on the side and EV electric on the other side.  In between there's a hybrid, 就是混合动力车. Right? Have you ever driven a hybrid car before?


I've never driven one, but I have been in them before. I have seen them working,  but I've never driven one myself.


I've never driven them. I've seen them on the road. Does that mean that there is like a switch thing that you can just switch between gas and electricity?


It basically does it all automatically. When you're at a like a low speed, you automatically just use the electric power as long as there is some stored within the battery.  Once the battery is depleted, then it goes back to the gas engine. The gas engine moves the car and while the car is moving, it's charging the battery.


I see, so this is very different from what I would imagine. I thought it was like a button or something.


Yeah, no, it's but I think some of them do have a button that you can push to just stay on electric power or just stay on gas power, but I've never driven one, so I've never really looked at the panels there.


I see. Now apart from gas hybrid EV,  I've also heard something called hydrogen就是氢动力车. What is that? Is that what car makers are working on right now?


So hydrogen power is another way to power cars. So there's actually two ways you can do this. You can use hydrogen power to charge a battery which causes an electric motor to move. But you can also use hydrogen to just like a gas or petrol power. And so you can use an old engine and basically just power the car the same way. So it
