Social Entrepreneur Alice Min Soo Chun Brightens the World with Her SolarPuff

by Debra Lau Whelan


Alice Min Soo Chun wants to change the way we light up the world. The inventor and social entrepreneur has spent more than a decade jumping from one war-torn region and natural disaster zone to the next, delivering thousands of her SolarPuff lights to places like Haiti, Puerto Rico, Ukraine, and Turkey.

Alice Min Soo Chun with her invention the SolarPuffMade with waterproof sail cloth, Chun’s foldable lanterns aren’t just a source of light for those without electricity; they help cut down on crime--particularly assault and rape--and comfort those suffering from post traumatic stress disorder (PTSD).

Chun’s interest in solar energy started in 2005, when her son, Quinn, was diagnosed with pollution-related asthma. Then a professor of architectural design and material technology at Columbia University, Chun turned her classroom into an innovation lab, challenging her students to create a solar light for use in disaster relief areas. What started off as a blow-up inflatable prototype has turned into an award-winning, origami-inspired, pop-up light that has garnered support from the likes of Bill and Hillary Clinton and Disney CEO Bob Iger.

Chun was raised by her grandparents in Seoul, Korea, and moved to Syracuse, NY, at the age of four to join her architect dad and painter mom, who taught her the art of origami. As the only Asian kid at her upstate suburban school, Chun was often bullied and beaten. “But I didn't fight with my fists,” she says. “I fought with the light in my heart and my mind.” Chun’s parents moved back to Korea when she was 15, but the teen stayed in the U.S., earning a bachelor’s degree at Penn State and a master’s at the University of Pennsylvania before becoming an architect and professor.

The New York-based Chun is now CEO of Solight Design, a company that offers a range of personal solar light sources, including the latest MegaPuff, the “next-generation” disaster relief light that’s larger, brighter, and includes a phone charger. “It’s extremely bright and has a red distress signal.” The company, which aims to make a difference by providing clean light and “making it accessible to all” also partners with the Clinton Global Initiative, Save the Children, and the United Way, and anyone can help donate through its Give a Light program.

We spoke to Chun about color therapy, the difficulty of securing venture capital funding, and her most recent trip to deliver lights to Turkey’s earthquake victims.

Children with SolarPuff in TurkeyYou recently got back from Turkey. What was it like?

I got there on April 19 and went to Hatay, which is the epicenter of the earthquake. The earthquake happened on February 6, 2023, and there was still so much rubble it looked like a warzone.

How many lights did you deliver?

I met with my NGO friends at Operation Blessing, who were distributing 500 boxes of food a day. We went into a tent camp in a stadium and AFAD, Turkey’s version of FEMA, distributed 600 SolarPuffs.

You literally packed the lights in suitcases and carried them yourself!

I should have brought more because a few days after that, I went to another tent camp, set up by NATO and the Turkish Ministry of National Education. It was a school with each tent a classroom. There were rows and rows of these tents that went on for miles, and there were thousands of middle school kids there.

Family with SolarPuff in UkraineAnd before that, you were in Ukraine delivering lights last December.

When the [2022] war broke out, I spoke to a friend with a sister who’s a nurse in the children's hospital in Lviv. She said the kids all had PTSD from hearing the air raid sirens during the eight-hour blackouts. It took hours for the nurses to calm them down. I remembered that our lights, which have six different colors, were used for children with PTSD after Hurricane Maria [in 2017] hit Puerto Rico. It helped the kids sleep better at night.

How did you get into the country?


It took me three days. I flew into Krakow, Poland, and then took two trains to get across the border. It was so dark when I got off the train that I actually tripped and fell walking down the street and fractured my ribs. There was an ABC News crew in Kyiv that met me at the train station and followed me around.

You arrived a day after Christmas, so you must have felt like Santa.

My son is 18 and in college, and I have empty nest syndrome, so that's why I wanted to go to Ukraine during Christmas and New Year’s to give lights to kids who are alone in hospitals during the holidays. All the kids came up to me while we were passing out the lights. They were so excited, especially a two-year-old boy who had a broken foot with a cast. He was limping and running back and forth asking me to give his friend a light, too.

Why do you deliver the lights yourself instead of ship them?


I met this girl who witnessed 12 of her family members who were shot and killed in front of her, and she was the only survivor. There are many, many other stories like that from kids in similar situations. They all have this trauma. It's important for me to tell them the story of how they have this incredible light and power inside themselves, which is the symbol of the SolarPuff.

Tell us the story behind the SolarPuff?


We invented these foldable cubes because we wanted to help people who were living in the dark without access to electricity. The solar light is like magic for these kids because they’re flat, and then they pop open into a great cube. I tell them, “This light gets its energy from the sun, and the Russians can't take the sun away from you. But the light of your heart and your imagination is more powerful than the sun, and you have to keep fighting with that light. Don't fight with your fists, fight with this light and your dreams and ambitions will grow.” It’s important for me to give the message that they're not alone and we care. It’s more valuable than the actual product itself.

Are you ever afraid to go to war zones and disaster areas?

People tell me not to go because of the danger, but it’s important to be able to tell them, “You matter, and I've come halfway across the world to tell you that you matter, and we haven't forgotten about you.” That’s more important than me being in danger.

Your son was little when you first went to Haiti in 2010. Did it ever cross your mind that you wouldn't come back?


I was never really afraid. There was another earthquake in Haiti last year, and I went back. The earthquake happened after the Prime Minister was assassinated, so there was a lot of rioting. I told my son, “There’s a chance I might not come back because it’s very dangerous. But the reason I'm doing this is because all of these children need our help.” My son said, “Mom, I know you're gonna come back. Stop being so dramatic.” As soon as I got there, my son saw some pictures of the kids getting the lights, and he's like, “I'm proud of you, mom.” I started crying. I get the reward of seeing the impact that it has, especially with children. It really transforms their world.

Did you create the SolarPuff with the intention of helping so many people around the globe?


There's never a straight line with inventions. There's always this kind of intersection between the straight line and the chaotic line of time. I was initially focused on solar energy because the environment is a global issue, but when the Haiti earthquake happened in 2010, the chaos of that intersected with my timeline. I decided to use this research to help Haiti.

Is that when you went from being a professor to a social entrepreneur?


I turned into a social entrepreneur when I learned that the Haitans were spending up to 30 percent of their income on kerosene. They could save that money for food, clothing, and education. Also, there are more carbon emissions from kerosene light than any lighting we use. One small solar light being used for ambient light instead of a regular light bulb can save 90 pounds of carbon emissions in an hour.

Sounds like the timing was perfect; you were developing the SolarPuff just as Haiti’s earthquake struck?


Studying by SolarPuff in HaitiI did three years of field testing in Haiti before launching our company. At first, I brought 500 lights into Haiti that were handmade and glued together. We gave them to these women farmers in the central plateau and one said, “This is a gift from God,” and started singing and dancing. Her voice was so raspy, because the smoke from the kerosene she used for cooking made her sound like she was smoking 10 packs of cigarettes a day. She couldn’t afford the glass that goes around her kerosene lamp. That’s why the smoke was especially bad. She had five kids in a one room house, and their eyes were stinging, and they were coughing while doing their homework.

Your lights play another important role--they keep people safe.


There are 1.5 million Haitian people left homeless and living in tent camps. Children get kidnapped and women get assaulted at night going to the bathroom. When they passed out solar lights at the medical clinic they noticed a 20 to 30 percent drop in assaults the next day.

You met Bill Clinton on your Haiti trip.


During my time in Haiti, I was invited to a Green Tech Expo and President Bill Clinton and the Haitian President [Michel Martelly] walked in. I showed [Clinton] my glued and taped SolarPuff, and fast forward seven years, I delivered over 100,000 lights to Puerto Rico after Hurricane Maria.

And then you met Hillary there, right?


That's when I met Hillary Clinton and told her the story of how I went to Dominica to deliver lights. She loved the message of the SolarPuff, and asked me to be in her book (The Book of Gutsy Women, (S&S, 2020)), and then she asked me to be in the docuseries, Gutsy. Then somebody on Bob Iger’s (the COO of Walt Disney Company) team saw [my episode of] Gutsy, and read up on me. [Iger] wanted to meet me, so I had a zoom call with him and his chief of staff, and he donated lights for Ukraine.

Didn’t Hillary end up helping you in Ukraine?


Before I got to Kyiv, I didn't know anyone at the children's hospital, Ohmatdyt, so I texted Hillary to ask for a name. She gave me five. When we finally got into Kyiv, they were ready for us and welcomed us with open arms. I sent Hillary pictures of the light drops in the hospitals the entire time I was there.

Is it difficult to get funding as a woman?


It's very hard to get VC (venture capital) funding, especially in a man’s world. Every time I meet someone, they say, “Why isn't the SolarPuff everywhere? Why haven’t I heard about this before?” It’s because there’s $86 billion in global VC investments, but only 0.01 percent of U.S. IPOs are female-led companies.

So there are two strikes against you?


A lot of companies say, “We’re making efforts to be more diverse,” but I haven't seen that happening in our case.

It must be discouraging because you have a proven product.

I'm grateful for all the things I'm learning within this process. I don’t think of it as a failure. I think of it as progress. So when the time is right, we'll be ready, and everything is about preparing for that moment.

What advice do you have for someone trying to become a successful entrepreneur?


The first step is understanding what your passion and gift is. It’s being able to find a project or a problem that you feel passionate about solving. It has to help others, solve problems for others, and make their lives better. Once that happens, then you start sharing that story, and it becomes a ripple effect of putting it out into the world.

You make it sound easy.

There are so many people who give up, and it's because they don't have the grit or the passion to keep going. If you don't have that passion for whatever you're doing, you'll end up giving up. Never give up, and don't listen to the naysayers. You're always gonna get haters. You have to overcome that and have the strength to block that out.
