WTF Fun Fact 13529 – Beer Powered Motorcycle

Would you drive a beer powered motorcycle?

When it comes to invention and innovation, few names light up the room like Ky Michaelson, a Minnesota legend better known by his nickname, “the Rocketman.” With a lifetime of exploits in speed and engineering, from partnering with deaf stuntwoman Kitty O’Neil to setting over 70 state, national, and international speed records, Michaelson is a man who seems to never run out of fuel—both literally and metaphorically.

However, his latest project, a motorcycle powered by beer, adds another layer of allure to his already fascinating life story.

From Speed Records to Stuntman Collaborations

To begin appreciating the significance of the beer-powered motorcycle, it’s essential to dive into Michaelson’s career first. His roots in speed started with his partnership with Kitty O’Neil during the 1970s. O’Neil set the land speed record for the fastest woman on four wheels in 1976, reaching an eye-watering speed of 512 miles per hour. Michaelson’s reputation gained more traction after his work with O’Neil caught the attention of Hollywood stuntman Dar Robinson. Together, they worked on projects for movies like Logan’s Run, Airplane, the Police Academy series, and Lethal Weapon until Robinson’s untimely death in 1986.

Return to Rocket Roots

After Robinson’s death, Michaelson returned to Minnesota and went back to his first love: rockets. This man is not just about speed; he’s also about the extraordinary means to achieve it. He’s built a rocket-powered toilet and set a Guinness record with a rocket-powered snowmobile. Even his kitchen gadgets are high-speed, like a high-speed margarita maker with a weed-eater motor. Michaelson’s imagination knows no bounds, as he continually seeks to innovate and defy the norm.

Beer-Powered Motorcycle Innovation

Perhaps his most extraordinary creation is the beer-powered motorcycle. Designed alongside his son, Buddy, this unique machine swaps out the conventional gas engine for a 14-gallon keg. Yes, you read that correctly.

The motorcycle is fueled by beer heated to over 300 degrees Fahrenheit. This allows it to generate enough steam power to propel the bike forward. Interestingly, Ky Michaelson is not a drinker, making the choice of beer as fuel even more fascinating.

His pragmatic viewpoint? “The price of gas is getting up there. I don’t drink, so I can’t think of anything better than to use it for fuel.”

The Science Behind the Suds

The beer in the 14-gallon keg is heated by a coil until it reaches a boiling point of 300 degrees Fahrenheit. Once it hits this temperature, the steam is forced out through a nozzle at the back of the bike, providing the thrust necessary for propulsion.

According to Michaelson’s calculations, the bike should be able to reach a top speed of about 150 miles per hour, although this hasn’t been tested yet.

Future of the Beer Powered Motorcycle

While the bike has already been showcased at local events and won awards, Michaelson aims to test its full capabilities at a drag strip soon. What’s more, the beer-cycle may eventually find its way into his in-house museum, alongside other fascinating inventions.

Interestingly, it doesn’t have to be beer fuel. Buddy, Michaelson’s son, stated that virtually any beverage could power the bike, opening the doors to further innovation. Could we see a coffee-powered or even Red Bull-powered version of the bike soon? Only time will tell.

So, the next time you pour yourself a cold beer, take a moment to think of Ky Michaelson, a man who saw a tankard not as a vessel for a drink, but as a fuel tank for uncharted possibilities. Cheers to that.

WTF Fun Fact 12889 – Dasia Taylor’s Life-Saving Sutures

Anywhere from 2% to 5% of surgical incisions and other stitched-up lacerations get infected, and it can be life-threatening. That’s partly because patients may not know their wounds are infected until they see signs like redness or experience pain. Teenager Dasia Taylor has an answer – she invented sutures that turn a different color when a wound is infected.

Dasia Taylor’s suture solution

When she began the project in October 2019, Dasia Taylor was just 17 years old. The Iowa City West High School student was participating in science fairs and was eventually named one of 40 finalists in the Regeneron Science Talent Search, a highly prestigious science and math competition for high school seniors.

Her invention was a suture threat used for medical stitches that changes color from bright red to dark purple when an infection is present. She uses beet juice to make the dye. But it’s far more chemically complicated than that.

Color-changing sutures save lives

Dasia Taylor’s invention is designed in part to help people who don’t have access to convenient medical care and is based on a process already known to scientists.

According to Smithsonian Magazine (cited below): “Taylor had read about sutures coated with a conductive material that can sense the status of a wound by changes in electrical resistance, and relay that information to the smartphones or computers of patients and doctors. While these ‘smart’ sutures could help in the United States, the expensive tool might be less applicable to people in developing countries, where internet access and mobile technology is sometimes lacking.“

While less than 5% of people in the US whose wounds are treated with sutures develop an infection, that number jumps to 11% in developing countries.

Taylor is also concerned about the high rate of C-section infections in parts of Africa and the US (the US has just as high of a rate of infection – sometimes higher – than some African nations with fewer medical resources).

How do color-changing sutures work?

So, how do the sutures help notify patients of an infection? Well, according to Smithsonian: “Healthy human skin is naturally acidic, with a pH around five. But when a wound becomes infected, its pH goes up to about nine. Changes in pH can be detected without electronics; many fruits and vegetables are natural indicators that change color at different pH levels.”

“I found that beets changed color at the perfect pH point,” said Taylor. Bright red beet juice turns dark purple at a pH of nine. “That’s perfect for an infected wound. And so, I was like, ‘Oh, okay. So beets is where it’s at.’”

But that wasn’t the full solution. Taylor also had to find a material that would hold onto the dye while not being too thick to be used as a suture. She tackled the problem during the COVID lockdown and ran experiments until she found the best of the 10 materials she was trying – a cotton-polyester blend that could change color in just minutes of picking up a change in pH.

There are still some kinks to work out before it goes from the laboratory to the bedside, but it’s safe to say this teen is on her way to an illustrious research career. – WTF fun facts
