Ninety percent water and ten ethanol or alcohol is the fuel source for the Horizon. The solution is just like of vodka, wherein the Horizon fuel cell kit directly converts ethanol to electricity free from noise and combustion. This device has the ability to run for day’s non-stop. In the next years to come, this device may have the chance to replace the traditional way of charging or electronic devices like our cell phone, iPods, mp3 players, and more. With its price of $99.00, I guess it’s already worth it since it will let us save from electricity in the long run.
