Good idea. For the projects sake I hope many people show interest in it.
Wish I had such enthusiastic teachers back in the school days...

Awesome! I wish all science classes were like that.

Only problem is, burning vegetable oil releases much more pollution to the atmosphere than regular oil. It is excellent project but it pretty much beats the purpose. We should reinvent car engines altogether instead of using different types of oils.

I hope that the kids don't lose interest later with their teachers trying to make them just another brick in the wall.

Science is about fun thing around you. As in previous video about traffic control, if you put fun in things people will be much more productive. People learn on Snotr actual science sometimes just because it is fun.

Independent from...
...Crude Oil?
Dependent from palm oil gained from the burnt rain forests of Malaysia?
Great thing!
Or does the plant oil come from Brasilia, where aborigines are banned from their own country to destroy the rain forest? To return later and find a poisoned unusable desert where nothing useful is growing any more for many years?
I don't want to make hope, that with hydrogen or any further energy the bus would run more sustainable. Furthermore I don't know the drivetechnology, which enhances efficiency by far compared with technology of today. And buses are more sustainable than cars for anyone.
But the given message, that plant oil driven cars are anyhow better, than cars driven by crude oil, is a message of yesterday. Today it tells the story of mankind, which doesn't want to react on reality an instead of this continues with old behavior and fills the food of the poor peoples in their car tank.
The better Message would be people, who drive very small cars, who organize their homes near the working place and who save energy where ever possible (per example by very good isolated buildings). That behavior could give the world a future for all.

This is really a great way to open up their eyes for science, well, I think people here in Sweden kinda throws away that chance which is granted to them. Some people in my class skipped classes such as science. But I definately did enyoj my time in school, since I used to go on Extra Science classes, and I'm proud of saying that I don't regret it one bit.

Dr. Ben, you're awesome! And I approve of you!!
