GOOD Energy Meetup Idea: Build a Battery with Pocket Change

Another idea for the GOOD Energy Meetup: making batteries out of pennies, nickels, and lemon juice.

On Thursday, February 24, GOOD is throwing a Meetup Everywhere, our big GOOD Energy Party. Below is just one sample idea for a meetup, if you're looking for some inspiration. To learn more about our first ever distributed, nationwide meetup of people who give a damn, check out our announcement post. For other GOOD Energy Meetup ideas, check out the super simple Energy 101 teach-in or the Mr. Wizard electricity episode screening.


This is a fun look at electrical cells, or batteries. With under a dollar's worth of pennies and nickels and some lemon juice, you can make a battery that's a lot more impressive than your typical potato or lemon battery that you might have made in elementary school.

Here's the Household Hacker with a video on how to do it:

Here's another look at making batteries out of money (or potatoes) by the clever scientist/cartoonist Tim Hunkin.


Hunkin has some other great science experiments collected on his site, which are well worth checking out.

We'll be building batteries at the New York City meetup, and would love to hear of others doing the same.

Important note: Take pictures or video and send them to us after your meetup. We'll feature your event in a roundup of our big nationwide meetup.

And during the event, use the hashtag #goodenergy to tweet about your gathering.

We'll be posting more meetup ideas at GOOD's Environment hub all week, so check back soon.

Sin City is doing something good for its less fortunate citizens as well as those who've broken the law this month. The city of Las Vegas, Nevada will drop any parking ticket fines for those who make a donation to a local food bank.

A parking ticket can cost up to $100 in Las Vegas but the whole thing can be forgiven by bringing in non-perishable food items of equal or greater value to the Parking Services Offices at 500 S. Main Street through December 16.

The program is designed to help the less fortunate during the holidays.

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."
