International Hackathon Competition for Primary and Secondary School Students Focused on Smart City Development
Patronage of the Czech participation in the Spanish-Czech Challenge HackaTEEN 2026: Libor Sečka, Ambassador of the Czech Republic to Spain
Meet the young innovators from Czechia and Spain who will showcase their ideas at the Smart City Expo World Congress in Barcelona as part of the Spanish-Czech Challenge HackaTEEN 2026!
1st Place
A proposal to install solar-powered pergolas and mobile greenery in public spaces where planting trees is not possible. The solution provides shade, helps reduce urban temperatures, and generates renewable electricity.
2nd Place
A mobile app concept designed to make route planning easier for people with disabilities. It brings together accessibility information in one place, helping users find suitable routes without spending hours researching potential obstacles.
3rd Place
A digital platform concept designed to help municipalities manage drought and water resources more effectively. It brings together essential information, interactive maps, and expert contacts in one place, making it easier for mayors to plan measures and respond to water shortages.
An app concept that uses city surveillance cameras to monitor flooding risks in real time during heavy rainfall. An interactive map alerts residents and tourists to dangerous areas and provides recommendations on how to stay safe.
A proposal to transform ordinary bus stops into climate shelters that protect people from extreme heat. The stops would feature greenery, water mist cooling systems, solar panels, and smart sensors to manage energy consumption efficiently.
A proposal for a system that converts organic waste from supermarkets into energy. Through fermentation, the waste produces gas that powers an electricity generator. The electricity is then used to charge portable power banks that customers can borrow while shopping. The goal is to turn food waste into a useful energy resource.
The other teams are listed in the order in which they presented their proposals. This order does not reflect their final ranking in the competition.
A mobile app concept designed to help residents and tourists discover small local businesses, access discount vouchers, and support the local economy. The goal is to attract more customers to independent shops and services that face growing competition from large international chains.
An intelligent system concept designed to help city surveillance operators monitor public spaces more effectively. The technology analyses camera footage, highlights important events, and reduces the risk of incidents going unnoticed. All final decisions remain in human hands.
A mobile app concept that connects young people with similar needs and lifestyles to help them find shared housing. The project combines cooperative and shared housing principles to reduce living costs and make independent living more accessible to young people.
A proposal to connect and expand the city's cycling network, making it safer for cyclists to travel without navigating dangerous sections of road traffic. The solution includes improved lighting, protected bike lanes, and a bicycle traffic monitoring system to support better infrastructure planning.
A proposal for a plastic bottle collection system that encourages recycling through rewards. Residents earn points for returning bottles, which they can redeem at local businesses. The collected material can be reused to produce urban furniture, such as benches.
A system concept that collects rainwater, stores it in underground tanks, and uses it for irrigation during dry periods. Artificial intelligence identifies areas affected by drought and manages water distribution based on current needs. The team proposes testing the solution near their school and football field.
A proposal to transform urban streets into more welcoming spaces for social interaction and community life. By reducing some parking spaces and introducing more greenery and pedestrian areas, the team aims to give public spaces back to people and create more opportunities for neighbours to meet.
