## Questions & Answers

**Q: Wouldn't this solve the world energy crisis?**
A: You may want to take a look at this - the idea may work for developing countries. http://www.smithsonianmag.com/innovation/a-potato-battery-can-light-up-a-room-for-over-a-month-180948260/?no-ist

**Q: Is this an alarm clock, or is it just for timekeeping?**
A: Just a clock. Not alarm.

**Q: How long does it run on the potatoes?**
A: We had it for about a week and it ran strong. The potatoes started to look bad so we threw the whole thing out. I imagine it would run the clock until the potato went completely bad.

**Q: Followed directions about setting time, but didn't work. Any hints?**
A: Here are the instructions for setting the clock. These are provided with the kit as well.
SETTING THE CLOCK
1. Setting the clock 
When all the metal plates are first inserted into the potatoes, the LED screen will light up and will show a static display of  "12:00". Press A once, the clock will start working. You will see the two dots in the middle start flashing. Press B twice to obtain the set month mode, then press A to adjust to the right month. Press B to confirm and the display will switch to the set day mode. Press A to adjust to the right day. Press B to confirm and switch to the set hour mode. Press A to adjust to the right hour. Press B to confirm and switch to the set minute mode. Press A  to adjust to the right minute and press B to confirm. After the minute is confirmed, press A once. The set time will be displayed.
