As kids they created all kinds of inventions. As adults – they’re dedicated to keeping your coffee warm.
Coffee starts hot and goes cool – somewhere in between you have a limited time to drink it. Two mechanical engineers think they’ve come up with a way to keep it at the Goldilocks temperature– just right–and keep it there for up to three hours.
They call themselves the two Daves — Dave Petrillo and Dave Jackson. They’re mechanical engineers who grew up across the street from each other in Pennington, New Jersey. And they’re born inventors.
During their wonder years they turned a chainsaw into a power scooter, built potato guns, and put sideways wheels on a mousetrap car.
In 2011 they left good jobs on opposite coasts and came together again. This time to solve the age old problem
The inspiration was simple said Dave Jackson, “I was tired of burning my mouth on coffee that was too hot … or waiting for coffee to cool down.”
Their solution? Coffee Joulies, shiny stainless steel beans filled with a heat-absorbing material. They take about the same amount of space as cream would, yet they do something magical. They immediately cool a hot cup of coffee to 140-degrees – perfect for sipping – and keep it there for as long as 3 hours.
Think how that would come in handy on a long drive – or just a day at the office.
The secret is non-toxic phase change material sealed within the steel beans. They absorb extra thermal energy and cool down your drink to a drinkable temperature three times faster than normal. Then they release that stored energy back into your coffee to keep the temperature stable.
Once your coffee’s gone, you can wash off your Joulies and re-use them over and over.
Not a coffee drinker? You can use Joulies with hot tea, hot chocolate…any hot beverage you want.
The inventors used crowdsourcing website Kickstarter to raise the initial funds for their Coffee Joulies. They made $575,000 in sales their first year (reinvesting all but $50,000), and expect sales to top $1 million soon. Hey – they convinced all five Shark Tank judges to part with $150,000 — so they must be doing something right.

Inventors Dave Petrillo and Dave Jackson exemplify an axiom featured on our website: Think around your frustration.
A burned tongue led them to invent Coffee Joulies – stainless steel beans that let you cool your coffee faster and keep enjoying it longer. Now Why Didn’t I Think of That?
