Hey, I need to look at various energy storage methods and draw comparisons between them on things such cost, power output, environmental impact and safety etc etc. I have chosen a pumped storage unit, a fuel cell, a super-capacitor, and a lead acid battery. Im sure there are many more but I have chosen these. How would I calculate the watts per day I could potentially achieve from a super-capacitor and the fuel cell. I need to continuously keep a 1 watt LED lit for 24 hours using each of the mentioned technologies and conclude which is the most suitable. Thanks |

I will not solve this problem for you because it is fairly involved. However, I will give you the general concept for solution. That is you have to normalize the power stored in each device, i.e. how many watts are stored in each device. The rest is just math. |
