Earlier this month, we ran an article in regards to the Method Solar Grand Prix, a observe race that additionally serves because the qualifier for the American Photo voltaic Problem, an overland race for faculty photo voltaic automotive groups. One of many cool issues about this yr’s race is that they added lessons for barely extra sensible automobiles to maintain the groups from straying as removed from automotive actuality as standard. In different phrases, they wished the automobiles to be just a little extra helpful, giving additional factors for extra seats.
After qualifying for the lengthy race, groups went onto a 1400-mile race that occurs in 4 levels over 8 racing days, together with varied checkpoints and stops. In 2022, this implies it occurred over 10 calendar days. Which may sound gradual (many drivers can do 1400 miles in solely a day or two with regular automobiles), however when your solely energy supply is the solar, it’s a way more troublesome feat.
Now, winners are being introduced. The College of Minnesota Photo voltaic Automobile Challenge workforce gained first place within the Multi-Occupant Automobile class, whereas the MIT workforce gained the less-realistic single-occupant class. We haven’t heard a lot from MIT, however the College of Minnesota’s web site gave us extra details about their workforce’s win.
The College of Michigan Photo voltaic Automobile Challenge has been competing within the American Photo voltaic Problem since 1993, however that is the primary time they’ve ever completed first, having come second each classes seven instances beforehand.
“Our workforce has been at this for some time and we’ve had some unbelievable automobiles, however we’ve by no means been in a position to stand on prime of the rostrum earlier than,” stated Amber Zierden, a U of M mechanical engineering scholar and the workforce’s Director of Engineering. “There’s nothing higher than getting to construct one thing with your personal arms, after which after pouring 1000’s of hours into it, attending to race it throughout the nation with a few of your finest associates.”
The coed groups traveled greater than 1,400 miles alongside the Oregon Nationwide Historic Path from Independence, Missouri, to Twin Falls, Idaho, this yr. The competitors lasted 16 days in July and included 4 days of auto inspections, just a little “Method Solar Grand Prix” race, and culminating within the eight-day journey throughout the US.
College students on the College of Minnesota designed and created their very own motors for “Freya,” a photo voltaic automobile with two seats that may journey about 400 kilometers on a completely charged battery. The automotive’s 1,000-watt photo voltaic panel array expenses a lithium-ion battery beneath it. The one workforce on the contest who developed and constructed their very own motor, the workforce’s laborious work paid off.
“Each Amber and I had been on the race final yr once we had the battery fireplace,” stated Ivana Truong, a U of M biochemistry scholar and the workforce’s Director of Operations. “Over the course of the 2021-2022 faculty yr, I noticed how laborious our electrical workforce labored to design and construct a completely new battery and electrical system and the way all elements of the workforce took what we discovered from final yr’s race to make Freya extra ready for this race. I’m proud to be part of bringing house first place for our entire workforce, each previous and current.”
Freya suffered a deadly breakdown whereas ascending a slope in Raton Go, Colorado, through the 2021 American Photo voltaic Problem (which was rescheduled from 2020 owing to COVID-19). This yr’s important issue for the pupils was trekking one other hill — a virtually 20-mile lengthy incline in Wyoming.
The scholars have already begun work on the workforce’s subsequent automobile, which might be its fifteenth solar-powered car. In Fall 2023, they’ll debut it on the Bridgestone World Photo voltaic Problem, the world’s largest photo voltaic racing championship, wherein groups race all through Australia.
“It is a large success for our Photo voltaic Automobile Challenge college students,” stated Andrew Alleyne, dean of the U of M Faculty of Science and Engineering. “What I discover much more compelling is the time, effort, and ‘sweat fairness’ that goes into one thing like this. The talents, each technical and delicate, that the scholars acquired all year long are issues that may catapult them to success properly past what they discovered within the classroom.”
Why This Issues
Once we take into account that photo voltaic racing hasn’t modified so much for the reason that Eighties (at the very least on the floor), it’s simple to imagine that it’s a solar-powered highway to nowhere, however that couldn’t be farther from the reality.
As I identified in one other article a couple of workforce from Arizona, the historical past proves in any other case. A photo voltaic automobile occasion in Australia, for instance, pushed GM to develop new EV know-how. They not solely gained the race comfortably with their roly poly automotive (the Sunraycer), however this additionally led to GM creating the Impression, a prototype that ultimately grew to become the EV1. Even when the primary mass-produced electrical automobiles didn’t seem till a lot later, this was the primary time that fashionable electrical automobiles had been on the highway in any vital numbers. In the long run, GM returned the vehicles it had leased out and crushed them, however this sparked one thing else that nearly nobody would contest:
Few individuals know that we began Tesla when GM forcibly recalled all electrical automobiles from prospects in 2003 & then crushed them in a junkyard

Tesla’s preliminary years had been a battle, however the firm has since damaged via and proven that mass-produced electrical automobiles are possible, interesting, and even worthwhile. This put strain on different automakers to provide their very own electrical automobiles. Now we’re starting to see some vital progress being made by way of rising the variety of EVs on the highway.
In different phrases, yesterday’s seemingly meaningless photo voltaic automobile competitions have resulted in as we speak’s electrical automotive revolution. They not solely proved the know-how out; in addition they disseminated data and experience to people who would go on to work within the discipline. In addition they inspired others to take part.
Each participant in these competitions isn’t going to go on to be the subsequent Elon Musk, however most of them will turn into worthwhile gamers at some degree within the EV market. However, a number of of them will go on to make a contribution to the trade that they wouldn’t have been in a position to make if it weren’t for his or her expertise engaged on a workforce and getting stuff finished.
