Fuel cells to generate electricity that in turn powers a motor still rely on the very high energy density of hydrocarbon fuels - it's just a different way of converting the fuel's chemical energy into mechanical energy and work. They are certainly more efficient but so far their other drawbacks, mainly high cost and low power density, have prevented them from becoming a practical replacement for internal combustion engines in most mobile applications. As your post indicates this has been studied and worked on for many years and we're still a long ways from where we need to be for them to displace ICEs. The fact remains that in spite of inefficiency and pollution issues the ICE's relative simplicity, high power density, low cost, and quick refueling make for a very high bar for other technologies to achieve in order for them to become mainstream in applications where continuous high-power output is required. The ICE went from invention to mainstream very quickly (just a few decades) due to its above listed benefits and has remained dominate for over a century now. This is proof that ICEs are very good at what they do and that replacing them will be challenging. I don't think this is necessarily an insurmountable challenge but history shows that it will require technologies that we don't have yet.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
