Winner Halophilic Marine Agriculture: Transforming Saline Water into an Environment for Cultivating Edible Algae
Could you briefly describe your team’s concept?
Our project at Halophilic harnesses saline water bodies to grow a type of salt-resistant algae, Salicornia. This algae, once harvested, is safe for consumption and offers high economic value as a food source for restaurants.
The inspiration for this idea came from the severe saltwater intrusion in the Mekong Delta, where an abundance of water is rendered useless for agriculture due to salinity, leading to waste.
We hypothesized that in such saline environments, salt-tolerant plants would be highly effective. This led us to Salicornia, also known as sea asparagus, a plant capable of thriving in salinity levels of up to 40ppt (normal seawater is around 25-35ppt).
This technique of saline water cultivation is not simple; globally, it’s only been applied by us and another company named Marine Aquafuture in Hawaii. I collaborated with the founder of that company to form Halophilic Marine Agriculture (Halophilic MA) in Vietnam, aspiring to scale this hydroponic venture beyond the US borders.
For Halophilic MA to realize this concept, we must ensure a steady supply of seeds, train shrimp farming facilities in advanced cultivation methods, and conduct thorough market research to bring this plant variety to restaurants.
How many initial ideas did you have that didn’t reach the final stage?
There were none other; this concept represents the entirety of my career.
Saying that I’ve dedicated "my entire life" to developing this saltwater algae cultivation technology is accurate. I left behind my friends and hometown to live on a shrimp farm on the outskirts of Can Gio. I invested my whole heart into it, hoping that one day, restaurants throughout Vietnam will incorporate algae from saline waters into their dishes more commonly.
What was the most challenging part about making this idea a reality?
The biggest challenge was lacking a tangible, edible algae product to showcase on stage. To prove the viability of my algae for restaurant use, I needed something more concrete than just slide presentations.
Luckily, two years ago, I filmed myself eating the processed algae, a video initially made for fun. I never anticipated that this footage would become crucial evidence that helped me clinch victory in the pitching contest.
I’m still amazed and delighted by this win, partly because the ideas from other teams were strong and partly because my product is relatively new and not yet prevalent in Vietnam’s market. I’m hopeful this win will accelerate its market introduction.
What significance does winning the Pitch Contest hold for you?
People often associate winning with the financial prize that helps materialize business concepts. While I am thankful for that, it’s not the only reward.
To me, the greatest value lies in the “human” aspect. Participating in the Pitch Contest exposed me to invaluable expert critiques. Having navigated past industry hurdles, these experts offered insights and experiences that are more precious to me than any prize.
Any advice for youngsters pitching next year?
Just take the leap and register.
You might falter in your presentation, lose your cool on stage, or struggle with articulation. Countless reasons might make you second-guess yourself.
But the relationships forged post-competition – with teammates, judges, and advisors – are immensely valuable, regardless of winning or losing.
I’ve faced failure, even repeatedly. I’ve been criticized and struggled with self-doubt. But all these experiences were mere stepping stones to where I am today. Those early feedback sessions equipped me with the necessary “life” experience to confidently step onto the pitch stage now.
Alternō Runner-Up - Innovative Sand Batteries for Thermal Energy Storage in Buildings
Can you give a brief overview of your team’s concept?
Alternō, formed by Kent Nguyen, Hai Ho, and Nguyen Quoc Nam, is pioneering a novel energy storage technology in Vietnam. Our groundbreaking product is the sand battery, utilizing surplus energy or solar panels as a “thermal energy reservoir” for extended periods.
A fundamental sand battery setup includes an insulated sand container with heat-conducting pipes immersed in the sand. This sand battery’s stored thermal energy can be utilized for heating or cooling buildings. For instance, our team developed the prototype capable of maintaining heat for months, sufficient for drying substantial amounts of agricultural produce.
How did you engage in sustainable practices before the competition?
I’ve practiced sustainable living since 2006, inspired by the documentary An Inconvenient Truth.
I prefer using an electric bike over a motorbike and have cultivated about 1000m2 of natural forest through a service. Moreover, I’ve transitioned to solar panels for electricity, reducing dependence on fossil fuels.
The main challenge in eco-friendly living is the expense. Sustainable products often come at a higher price, and you can control food sources when dining out or inadvertently engaging with non-sustainable businesses.
What was the greatest hurdle in actualizing this idea?
At first, we wanted a CTO (Chief Technology Officer) with a robust background in hardware, but we couldn’t find one. However, we found a CTO after joining Antler’s incubation program, clarifying our idea, securing a $110,000 investment, and participating in Qualcomm’s incubation for patenting. We obtained the initial investment to bring our concept to fruition.
Any memorable experiences from your idea development journey?
A defining moment was our visit to a coffee farm in Dak Lak, where the entire Alternō team saw firsthand the strenuous coffee drying methods of the farmers.
Farmers had to dry coffee in rudimentary wood-fired ovens akin to pigsties. Workers laboriously gathered tons of coffee spread across vast areas during sudden rainstorms.
This visit profoundly solidified the significance of our solution for the farming community. With a sand battery providing stored electric power, people wouldn’t have to engage in extensive manual labor.
People’s Choice Award Winner AquaGleam: Revolutionary Technology for Removing Ions and Metals from Contaminated Water
Could you encapsulate your team’s innovative idea?
AquaGleam’s initiative stems from tackling water pollution, which disrupts ecological balance and creates a scarcity of clean water. We’ve implemented ’Capacitive Deionization’ (CDI) technology, which is adept at extracting valuable metals from polluted water sources.
AquaGleam’s solution involves electrostatic attraction and a double-layer charge mechanism to extract ions from water, known as capacitive deionization. CDI functions by applying voltage across two electrodes coated with porous activated carbon, merging adsorption, and the effects of electric fields to isolate ions and charged particles. This process purifies the water by removing these ions.
How did you engage in eco-friendly practices before the competition?
Dung: “Living sustainably in Hanoi is not easy. For instance, using public transport in Hanoi, especially during rush hours, is a challenge.
In an effort to achieve sustainable living, I choose the bus and other public transport methods as my main ways of getting around, and I also prefer ridesharing services that use electric vehicles like Xanh SM.”
Lan Anh: “One interesting sustainable practice I learned from my boss is ‘digitization’ of daily tasks. Instead of writing notes on paper, I’ve shifted to digital tools for handling tasks.”
Hao: “I usually walk or bike to school. I find that walking and biking not only reduce pollution emissions but are also beneficial for physical health.”
What is a standout memory from your team’s idea development phase?
One of the most unforgettable instances was a major disagreement we had while finalizing our idea. Given our diverse professional backgrounds, disagreements are inevitable. At times, our discussions became so heated that the group ceased functioning for a few days.
