3:11 is called a tensegrity structure

1:45 woah there buddy calm down😅

how are you suppose to use the flash light at night

I made a wind powered lego car recently but it just has a battery powered propeller and that version unsurprisingly works pretty well. With what you did, why not just make car with a sail on it, it would work much better...

Also the solar powered flashlight sounds like perpetuum mobile until you factor in efficiency. :D

as it turns out, the most efficient wind capturing device to attach to a vehicle is a sail.

my dad has one of the weighted Lego pieces from when he was a kid

try making a small very light train with only one motor so you can try the solar panel on it.

Man I love physics and Lego combined

13:26 Bro looks like frickin palpitine “execute order 66” 💀💀

The electric car has mending irl bro

WOAH these are really weird concepts but extremely cool

Getting the kinetic energy back when braking is called regenerative braking.

This video is as educational as a 5th grade science class and is muuuuuucccccchhhhhhh more entertaining

This is so amazing 👏❤!

Sowas nennt man auch Lichtmaschine bei Verbrennermotoren um Strom zu erzeugen!

Try the solar powered train with two solar panels and outside on a sunny day, light levels indoors are much lower than outdoors.

Can you build a Lego fire station for your Lego city?

There are projects with motorized LEGO aircraft that can take off and fly for real!

5:02 looks like a dragster

7:34  that’s called a counterweight in scientific terms btw also great and entertaining video!
