Thank you for meeting me. 00:00:00
Oh, not a problem. 00:00:04
Your aunt was telling me about your assignment. 00:00:05
She said you're doing research into future transportation. 00:00:07
Right. 00:00:09
We're researching what transportation will look like in 100 years. 00:00:10
Well, I can't predict the future, but I can tell you it should be very exciting. 00:00:13
Wow! 00:00:19
This is incredible! 00:00:21
Are you accepting applications for test drivers? 00:00:23
Not exactly. 00:00:26
But you can check it out. 00:00:27
What kind of car is this? 00:00:29
This is GM's Autonomy. 00:00:31
It's a concept car designed around fuel cell and bi-wire technology. 00:00:32
Fuel cell technology? 00:00:37
What's a fuel cell? 00:00:39
Fuel cells are like batteries, except as long as they're fed fuel, they keep producing energy. 00:00:41
They don't go flat or need recharging. 00:00:45
This particular type of fuel cell converts hydrogen and oxygen into water and produces 00:00:48
electricity and heat in the process. 00:00:53
So this car uses hydrogen for fuel instead of gasoline? 00:00:58
Yes, it does. 00:01:01
So how did you come up with the idea for the Autonomy? 00:01:03
Well, ideas for new vehicles can come from breakthroughs in technology, from formal processes 00:01:05
like consumer research, or from very informal processes like discussions in the office or 00:01:11
even ideas that pop into your head while you're driving. 00:01:17
Sounds a lot like brainstorming. 00:01:20
It is. 00:01:22
We brainstorm all the time. 00:01:23
When we hear customers talk about what they love about their vehicle or what they wish 00:01:24
it could do differently, it automatically makes us start thinking about solutions and 00:01:28
new designs. 00:01:32
Dr. D told us about the design process. 00:01:33
It seems like once you have brainstormed solutions for the problem, you have to do a lot of research. 00:01:36
It's really the scientific method in action. 00:01:41
To develop an idea into a vehicle, it's really just a long series of solving problems. 00:01:43
Before you can start solving those problems, you have to make sure you have all the data, 00:01:49
knowledge and information that you need. 00:01:52
For example, I need to make sure I'm not violating any of the laws of physics. 00:01:55
So you have to know about things like gravity and friction. 00:01:59
That's right. 00:02:02
And sometimes in the auto industry, we do consumer research to make sure that what we've 00:02:03
designed is really what people want. 00:02:07
One way to do that is to build a concept car. 00:02:10
So this is a concept car? 00:02:13
Right. 00:02:15
A concept car is a one-of-a-kind vehicle that helps engineers and designers study and learn. 00:02:16
What have you learned from this concept car? 00:02:21
A lot. 00:02:22
We learned that when you use fuel cells and bi-wire technology to drive a vehicle, you 00:02:23
no longer need an internal combustion engine, an automatic transmission, a gas tank or any 00:02:28
of the mechanical linkages that we have in cars today. 00:02:33
Those are really big parts that take up a lot of room. 00:02:37
Without them, the car doesn't have to look the same anymore and you're free to design 00:02:40
it differently inside and out. 00:02:44
Does it take a long time to develop a car from an idea to a real car that people can 00:02:47
buy? 00:02:51
In GM's concepts, the Pontiac Solstice went from concept to production in just about two 00:02:52
years. 00:02:57
And that's really fast. 00:02:58
But with a really futuristic vehicle like the Autonomy, it's different. 00:02:59
We're going to learn so much more before we're ready to produce it. 00:03:04
So the first fuel cell vehicles that are sold probably won't look like this. 00:03:07
It really depends on technology, on the purpose of the concept and what the public thinks 00:03:11
about it. 00:03:16
So not all concept cars are built? 00:03:17
That's right. 00:03:19
It takes a lot of people, time and money to build a concept vehicle. 00:03:20
So we try to make sure that we build the ones that are the best use of our resources. 00:03:23
The ones that are going to help us learn the most about technology, about our customers 00:03:27
and about our own capabilities. 00:03:32
It sounds like research is just as important in the design process as it is in the scientific 00:03:33
method. 00:03:37
Thank you. 00:03:38
You've been very helpful. 00:03:39
You're welcome. 00:03:40
And don't hesitate to call if you need anything. 00:03:41
So can I borrow the keys to the Autonomy for research? 00:03:43
Do you have a driver's license? 00:03:46
I'll have to get back to you on that one in like six months. 00:03:48
Okay Tony. 00:03:52
Tell your aunt I said hello. 00:03:53
I will. 00:03:54
Bye. 00:03:55
