Neocrete is a New Zealand based business focused on making concrete sustainable. Instead of emitting carbon into our atmosphere, imagine the buildings and infrastructure around us sequestering it. Instead of rain damaging these buildings, imagine them using the rain water to self-heal cracks. Imagine buildings as living, breathing organisms. For Neocrete this is not sci-fi fantasy, this is our business plan. We can currently replace up to 50% of the cement in concrete – with no loss in performance, including early strength – and were on track to completely replace cement by 2027. Concrete made with Neocrete is also more durable than conventional concrete. Neocrete is proven in projects around New Zealand and is about to start producing at scale for global pilots.

Blue Frontier has pioneered an innovative smart air conditioning system that operates with ultra-high efficiency. By adjusting the concentration of a salt solution, we achieve cooling with minimal energy consumption. This breakthrough enables our air conditioner to utilize less than half the electricity conventional systems require. Moreover, our A/C can operate without drawing electricity during its functioning, allowing us to shift energy consumption to non-peak periods—when electricity costs are lower and predominantly sourced from renewable energy. Beyond the imperative of energy conservation, our air conditioning system stands out as a superior alternative. Our technology enables the independent regulation of humidity and air temperature, a feat challenging to achieve with traditional A/C systems. Combined with intelligent distributed control systems, this capability ensures a consistent optimal comfort experience—never too hot or too cold, but just right.

Future Problem Solving, an international education nonprofit, proudly celebrates 50+ years of placing young people at the core of a dynamic, purposeful learning experience. Each year more than 30,000 K-12 students in at least 34 states and 14 countries around the world participate in a variety of problem-solving challenges. Our Future Problem Solving programs equip curious young people with the skills they need to create a better future. Problem solvers learn how to think, not what to think, and gain skills they need to succeed in work and life. Our proven educational outcomes are life changing for students. At the heart of Future Problem Solving, our nearly one million alumni provide the most valuable evidence. We are inspired by them and all who help us build a vibrant global community of problem solvers ready to create positive change in the world. Today’s educators find it challenging to fully address gaps in career readiness skills while also balancing their state and national education standards. By design, Future Problem Solving helps fill in the gaps with standard-based and skill-based resources to meaningfully engage young people in all the places and spaces they learn. Students gain broad general knowledge, a deeper understanding, and empathy as they apply higher-order thinking and complex problem-solving skills to real world issues. Help us create a better future by ensuring all students gain access to learning the critical and creative thinking skills they need to succeed today and in the future. There are many ways we can work together.
