First some basic vocab:
What is electrolysis?
Electrolysis is a scientific way of 'splitting' substances. Electrolysis means 'electric-splitting' and involves the separation of substances through an electric current. Metals above carbon in the reactivity series (potassium, sodium, lithium, calcium, magnesium and aluminium) are extracted by electrolysis.
What's the average horse power for a typical car?
A typical car in America has something around a 120-horsepower engine. A big SUV might have a 200-horsepower engine, and a tiny car might have only 70 horsepower.
What's a chassis?
Torque is a measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear space. Torque is what causes an object to accelerate rotationally.

Will hydrogen-powered cars drive us into the future?
Electric cars like Nissan's Leaf and the Tesla are grabbing all the headlines, but big car makers like Toyota and Hyundai are pumping billions into hydrogen-powered technology. Toyota, for instance, expects 30 percent of all vehicles to be hydrogen powered by 2050.
It's fair to say that hydrogen has a bit of a post-Hindenburg image problem, and who knows where you'll be able to fill up, but it's not just the giants of the automotive industry who are backing the technology.
A small hydrogen-fuelled car company Riversimple calls itself the only independent hydrogen car startup in the world. It's about to start trials of its 2-seater car the Rasa in Wales.
We speak to its CEO Hugo Spowers, a former petrol head who's converted to hydrogen fuel cell technology.
