If you spend a lot of time camping out in the wild, or cooking your meals on open fires, a new USB cooking pot might be an excellent way for you to charge your smartphone while away from the grid.
The new USB cooking pot, known as the Hatsuden-Nabe, uses excess heat to charge your smartphone, keeping it topped up while you prepare a brew. Developed by TES NewEnergy Corp., the Hatsuden-Nabe transforms waste heat into electric current.
How It Works
The 16 cm diameter pot has a thermoelectric material developed by TES NewEnergy Corp. at its base that takes advantage of a phenomenon known as the Seebeck effect. This effect occurs when there is a temperature difference between two different conductive materials, generating an electric current. In the case of the Hatsuden-Nabe, it uses the temperature difference between the heat source (~ 550 °C) and boiling water (~ 100 °C) to generate an electrical current of about 200 ~ 250 mA, which is enough to recharge a smartphone in 3 ~ 5 hours.
Practical Applications
The Hatsuden-Nabe is particularly useful for outdoor enthusiasts, campers, and survivalists who often find themselves far from conventional power sources. Imagine being able to charge your phone while cooking a meal or boiling water for coffee. This dual functionality makes it an essential tool for anyone who spends extended periods in nature. Additionally, it can be a lifesaver in emergency situations where keeping your phone charged is crucial for communication and navigation.
Moreover, the Hatsuden-Nabe is not just limited to camping. It can also be a valuable asset in developing countries where access to electricity is limited. By utilizing readily available heat sources, people can charge their electronic devices without relying on an unstable power grid. This can have significant implications for education, healthcare, and overall quality of life in these regions.
The new USB Cooking pot Hatsuden-Nabe is now on sale in Japan for $280. While the price may seem steep, the benefits it offers in terms of convenience, safety, and sustainability make it a worthwhile investment for many users.
The Hatsuden-Nabe is a groundbreaking innovation that combines the basic necessity of cooking with the modern need for electronic device charging. Its ability to convert waste heat into usable electrical energy makes it a versatile and practical tool for a wide range of applications. Whether you’re an avid camper, a survivalist, or someone living in an area with limited access to electricity, the Hatsuden-Nabe offers a reliable and efficient solution to keep your devices charged and ready for use.
