Transformers style truck converts into a train, runs on algae.

Trains are the most efficient way to move lots of big stuff over land, but the rail lines don't always go to where the goods need to be. With a special combination wheel design that can quickly convert from rail to road use, the Chiron transporter looks like something Optimus Prime would use when moving house. But by eliminating the need to shift the container over to a truck for the final leg of its journey, the Chiron is designed to save a lot of time and energy. Continuing the green theme, the Chiron's power is supposedly generated by an 'algae fuel cell', although no further information about how this wondrous power plant actually works is given. From the picture, it looks like the Chiron also works on good old fashioned electrified lines.

While I could come up with a host of practical problems including a lack of rear access for loading the container, you've got to admit that it looks pretty cool.
