For all the recent advance on the electric car market, it is good to see that other alternatives to fossil fuel transportation are also making progress. Low-emission-car pioneer Hyundai is soon to introduce a fuel cell version of its 2015 Tucson in Orange County that will run on biogas produced from human waste. The poo-car, as it’s been nicknamed, is to demonstrate the feasibility of locally produced hydrogen from renewable sources at a self-powered facility.
