I just read about New Holland's prototype of an incredible innovation; it is the New Holland NH2. The NH2 is a tractor based on their 76000 line of tractors, but the incredible aspect is that it is fueled by an hydrogen fuel cell. This caught my eye for a couple of reasons; 1- its an amazing innovation towards a greener future, 2- they are using fuel cells which is what Dustin Shindo started Hoku Scientific with (he is a big inspiration of mine), and 3- it just looks cool!

These are some pictures and it is still a prototype, but they are looking to commercialize it in as close to as 3 years out from now. It eliminates all diesel use and the exhaust pipe all current tractors have. There are zero emissions and there is only a little amount of water, in the form of stream, that is produced by the Fuel Cell System.
