Unconventional Vehicles and Alternative Fuels: A Journey Across the Americas

A Japanese company offers a DIY car kit called the K4, which is road-legal and can be assembled with common tools. The kit costs $8000 and takes a few days to build. Separately, Seth Warren and Tyler Brandt embarked on a 34,000 km journey from Alaska to Argentina using a truck powered by vegetable oil, promoting the use of alternative fuels. They used various oils, including waste frying oil, fish, soy, and palm oil, to fuel their trip, aiming to set an example for sustainable living.
