which is why i'm really excited. because toyot developed this software that can simulate head injuries and helps make people safer. then they shared this technology with researchers at wake forest to help reduce head injuries on the football field. so, you know, i can feel a bit better about my son playing football. [ male announcer ] how would you use toyota technology to make a better world? learn how to share your ideas at toyota.com/ideasforgood. my kids say i speak a different language. but i love math and math and science develop new ideas. we've used hydrogen in our plants for decades. the old hydrogen units were veryarge. recently, we've been able to reduce that. then our scientists said "what if we could make it small enough to produce and use hydrogen right on board a car, as part of a hydrogen system." this could significantly reduce emissions and increase fuel economy by as much as 80%.
