You recycle, reuse, store your food in glass containers for lunch at work and use the composting bin under the sink while ordering your monthly Metro Pass next to the solar powered coffee maker.

And now it’s time to take things one step further- literally.

How about charging your phone for free, while you walk? Every bit of energy counts, right?

SolePower has an insole that can harness your walking power and recharge your mobile devices, allowing you to leave conventional electricity behind.

That's right- charge your phone while you walk.

Here's how it started:

Developed out of a project done by students at Carnegie Mellon University in Pittsburgh, SolePower’s inventors Hahna Alexander and Matt Stanton originally designed an energy-harvesting shoe with embedded LED lights that would make walking around on campus at night safer for student users.

The project was such a success that the engineers became inspired. They wanted to take things further. They decided to design recharging insoles, and started a successful Kickstarter campaign in 2013.

O ne thing led to another and the group raised $60,000 USD, funding product development to help make the device more powerful, slimmer, and capable of storing the generated power.

And the rest is history.

As the company website says, “SolePower insoles are a power source as mobile as the devices they charge.”

The insoles , which are cut-to-fit, water resistant and meet podiatrist recommendations for size and comfort, can be placed inside your shoe. As you walk, the power you generate while moving is stored in an external waterproofed PowerPac that can attach to your shoe.

Once energy is gathered, mobile devices can be charged by connecting to the PowerPac’s USB port.

SolePower’s power source can charge almost any device that can be charged using a computer USB port, and at the same charging speed.

A pair of left and right SolePower Ensoles, along with two PowerPacs, currently has an expected price of $199.99 USD.

Sounds like the wave of the future.

Of note, SolePower: someday it would be a great idea to be able to power our homes by washing dishes. There are A LOT of dishes from the holidays, and I'm sure some people would appreciated it, if you're out there.
