The first radio control car that runs with soda ring cans or aluminium waste

Apr 15, 2011

A student and professor from the School of Industrial and Aeronautic Engineering of Terrassa (UPC-Barcelona Tech), have patented the dAlH2Orean, the first radio control car that runs with aluminium soda ring cans, or residual parts of aluminium mixed with hydroxide of sodium dissolved in water.

The dAlH2Orean, built by the student and the teacher of School of Industrial and Aeronautic Engineering of Terrassa and patented at Campus Energia, and patented by the UPC-Barcelona Tech, is the first radio control car powered by aluminium waste and water, using domestical sodium hydroxide as a catalyst. The whole operation is based on the self generation of hydrogen generated through the reaction of contact between aluminium and sodium hydroxide. This self generated hydrogen, feeds the fuel cell that produces the energy.

The residue of aluminium and sodium hydroxide dissolved in water are placed inside the tank car. The aluminium reacts with sodium hydroxide and generates hydrogen, which is filtered through a vinegar filter with water to remove traces of hydroxides. The hydrogen passes to another filter containing silica gel ball where it loses moisture to enhance its performance. Finally, hydrogen reaches the stack generating electricity through a membrane that separates electrons from the protons until they meet again in an environment of oxygen, producing water, and energy that powers the engine.
