Accelerating! The Serial Hybrid with in-wheel electric motors

My dream car is a radical departure from what we have today. Well not quite.. It will have four wheels. But they will be different. This picture hints at it:
Research into these motors is advancing nicely. Here is an exploded view of one version:


Why not have the kinetic energy produced right where it is needed? In the wheel itself! Several companies are now researching in-wheel motors. The next item for discussion is the battery. Tesla already has one with a range of 300 + kilometers. But I want 1,000 +. 


Advances in battery technology have not stopped. Check this quote from some research going on at Stanford University:

In this project, researchers Stanford University will seek to develop an "All-Electron Battery", a completely new class of electrical energy storage devices for electric vehicles that has the potential to provide ultra-high energy and power densities, while enabling extremely high cycle life. The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. This technology uses a novel architecture that has potential for very high energy density because it decouples the two functions of capacitors: charge separation and breakdown strength. If successful, this project will develop a completely new paradigm in energy storage for electrified vehicles that could revolutionize the electric vehicle industry and establish U.S. leadership in advanced energy storage technology for electric vehicles.

But there is more! Have you heard about the Wave Disk Generator? It is a completely new engine concept and looks a bit like this:


And here is a schematic of how it works:


This combustion engine will reduce emissions by 90% compared to conventional internal combustion engines. It will be perfect for recharging the batteries in your future electric car. With a 50 liter tank this serial hybrid concept will probably give you a range of 2,000km on one tank.

This dream of a combo will not hit your stores quite yet. But when it does, cars will become cheaper to build, cheaper to run and will become the darlings of Mother Earth!
