Nnaemeka Ikegwuonu is a "Hardware Maker" with a mission: using renewable energy to ensure that no African farmer loses their harvest to the sun.
In Nigeria, a staggering percentage of fresh produce never reaches the dinner table; instead, it rots in the heat of open-air markets and transit hubs.
Nnaemeka Ikegwuonu, a radio presenter turned innovator, saw this heartbreak firsthand while talking to rural farmers. He realized that the lack of a "cold chain" was the single biggest barrier to prosperity for smallholders.
His solution was ColdHubs: modular, solar-powered walk-in cold rooms that can be installed directly in markets. These hubs extend the shelf life of perishable foods from two days to more than twenty. Nnaemeka did not just design a box; he engineered a "Pay-As-You-Store" model. Farmers pay a small daily fee per crate: making industrial-grade cooling accessible to those who need it most.
Lessons Learned
1. Innovation Must Be Affordable.
2. Hardware is Hard, but Necessary.
3. Harness the Environment.
