Make Your Own Hydrogen Fuel Cell
A fuel cell is a cell that produces an electric current directly from a chemical reaction. hydrogen fuel cell is capable of producing electricity without any pollution because the only byproduct is pure water. Hydrogen fuel cells are the most common, used in spacecraft and other areas where there is a specific need for … Continue reading Make Your Own Hydrogen Fuel Cell
Recharge Your Batteries While You Walk
At the Center for Research in Advanced Materials (CIMAV), scientists found a way to “capture” the energy that people produce from walking. They designed a pill-shaped cylinder that they adapted to fit a shoe to store the mechanical-vibrational energy a person generates when walking. With this captured energy the scientists were able to recharge … Continue reading Recharge Your Batteries While You Walk
