Construction Materials and Economic Design

building to be, if you pardon the expression, kind of crude. You see exposed I-beams and everything. But when the air is only flowing 10 m an hour, you don't have to be particularly careful about streamlining everything. When it's running 130 mph, you better be very careful about how you streamline things. What is it actually made out of? berserk cuz there's not like a you can't just go on Google like how to build a wind tunnel. What What did you choose to Okay. Well, let me start. Let me let me do Let's do this right here. When you're building a race car, an airplane, or a rocket, it better be very, very lightweight. It better be made out of whatever materials you have at your disposal, carbon fiber, titanium, etc., etc. Wind tunnels are great big machines bolted to the earth. And even though there have been examples of people using high tech materials and once in a while it may be necessary but mo for the most part this wind tunnel is just a very big channel that's controlling the airflow. So using a lot of very expensive materials is not only unnecessary but you have to remember we did not have a big budget and uh it took us a while to get the financing even with all the money we brought up front and all the people the grassroots level people who were helpful in in making this thing happen. It still came down to we had to be absolutely as economical as possible. We didn't build this thing out of high-tech materials um for a very specific reason. It's the reason that your car is not built out of titanium. Uh it would cost 200,000, half a million, I don't know what, but you build it out of the materials you need
