Like the startups which try to make solar systems to condense drinking water from the air. They demonstrate it in wet climates where the idea works but the solar panels don't because it's cloudy and cool. Those environments don't need drinking water because they are rainy. Then they try it in deserts where the water is needed and the solar panel bit works, but the whole thing doesn't work because there's no water in the air - that's why the water is needed there(!).
