4. Umbrella for Catching Rain
What it is: a rain-collecting umbrella
Date of invention: 2013; average cost: $5–$10*
Rainwater harvesting is a widespread practice throughout almost all nations, including Japan. Japan has developed an umbrella that collects rainfall by fusing its love of umbrellas with rainfall collection technology. An umbrella typically costs 500–1,000 yen (about $5–$10 in the United States) in Japan.

Rain-collecting umbrellas are accessible in Japan, even if these innovations aren't yet listed on Amazon. The only drawback of this umbrella is that, in addition to your tilted umbrella, which directs water into the bag, you also need to carry a water storage bag. That can grow heavy if it rains a lot.
