Let’s face it, when it comes to renewable energy one of the major concerns is how they might be used to power that ever-useful instrument – the car. So with that in mind Horizon has made several over its renewable energy kits centered around hydrogen-powered toy cars!
Up first is the Fuel Cell Science Kit, which, despite its name, is centered around a car. It has a solar cell for cracking water into hydrogen & oxygen:
The idea behind these cars works on the combustibility of hydrogen gas and the ability to split ordinary water in hydrogen & oxygen gas with electricity. In this case a solar cell or batteries are used to crack the water into the gases, which are stored. Then when you want to run the car they are ignited and run a combustion engine not very different from the gasoline cars we use. The Fuel Cell Science kit car is set up so that when it hits an object it reverses 90 degrees and tries the new direction.
Horizon’s H-Racer Hydrogen Powered Car is the original model in this series. It is down to the basics with this unit. You crack the water and store it in either an external tank (inlcuded) or in the car’s own tank.
The HydroRacer, much like Fuel Cell Science Kit, has the visible gas system on board the car itself. But the car in this case is much fancier, with a more streamlined appearance and some LED’s inside the body for a more impressive appearance.
Last, but certainly not least is the H-Racer 2.0. With this model you get all the water cracking, hydrogen powered greatness of the H-Racer but with the benefit of also being a fully remote controlled car.
All of these, much like the kits, are great demonstrations of renewable energy and the power of hydrogen fuel. They also have the benefit of being nifty model cars on top of all that energy science!
