MICRO’s new Perpetual Motion Museum is open to the public in Rockefeller Center!

Be the first to discover why perpetual motion is impossible on MICRO’s whirling journey through earth’s energy system.

You can find the museum in Rockefeller Center’s Grand Concourse, opposite the BDFM Subway entrance.

Traveling from the Big Bang through to the light switches you touch every day, you will explore some of the most mysterious questions in the universe:

Why do things move? Why do they stop?


1 | join the inventors' quest


The inventors in MICRO’s Perpetual Motion Museum want to break the energy cycle and build perpetual motion machines. They want to create something out of nothing.

Silly inventors. If only they looked behind them!

Inventors have been trying to come up with perpetual motion machines for hundreds of years.

There are two designs for perpetual motion machines:

  1. Perpetual motion machines that try to run forever.

  2. Perpetual motion machines that try to “create” energy, putting out more energy than is going in.

But perpetual motion machines never work. Visit the museum to find out why!

Explore the energy cycle.

In this video, plants are using the sun’s energy to grow. The inventor eats the plants, and the sun’s energy passes into their body.

The inventor transforms the plants’ energy into chemical and mechanical energy to ride the bike. The bike’s mechanical energy turns a magnetic generator, and is transformed into electrical energy.

The electrical energy is stored in a battery, which powers the inventor’s workshop light. Energy is transforming all around us.



To understand the future, look to the past.

We started inventing and building machines long before we understood how energy works, or where it comes from.

And we’ve created amazing machines for harnessing and using energy. But we’ve made some mistakes along the way. 85% of the energy the human world consumes comes from non-renewable, polluting energy sources like fossil fuels.

What are fossil fuels? The sun’s energy, captured and stored by ancient plants and animals.

It takes millions of years to make fossil fuels. And when we burn fossil fuels in our machines, they release pollution as well as heat.

Perpetual Motion doesn’t work.

A fixed amount of energy goes into the process of making a wheel spin, and some of it escapes in ways we can’t avoid: sound, friction, heat.

Perpetual motion can’t solve our energy problems. We have to get better at harnessing, using, and storing the energy we already have. If we invented better ways to store energy, it would be easier to use “renewable” energies like wind and solar.

Storing energy is difficult for some of the same reasons that Perpetual Motion Machines don’t work. Whenever energy transforms, a portion of that energy escapes as heat. Put a fixed amount of energy in to storage. Take it out, and some of it will escape as heat.

But humans are crazy inventive.

Check out some of the storage inventions scientists and engineers are working on now!



What am I losing?

At MICRO, we measure units of energy as “burritos” just like the US Department of Energy!

Your body runs on energy, just like every machine you use. At the Perpetual Motion Museum, you can see energy escaping your body as heat in MICRO’s IR camera.

Today, the average American consumes 31,000 burritos of energy per year.

You’re only eating around 600 of those burritos to run your body... so what is eating all the rest? Your machines!

Not everyone has access to the same energy ‘diet.’ In fact, the same number of people are living without electricity today as back when the light bulb was first invented.


How do zoetropes work!?

If you’ve visited the Perpetual Motion Museum, you’ve seen MICRO’s incredible spinning zoetrope.

Magic? Science!

All animation - including everything you see on television - is made of a series of still images flashing at you very fast.

When this happens, your brain links the still images together, giving you the illusion of moving images. This is called the “phi phenomenon.”

When MICRO’s zoetrope starts spinning, a light flashes over the sculpture. Each flash of light shows your brain a still image of the zoetrope in a new position. Your brain fills in the gaps!
