"Germany: June heat wave linked to 5,000 excess deaths" While this refrigerator thing sounds funny, all of them would still be alive if they had this thing at the time before it happened. There are other cooling solutions too. Personally, this is too expensive.
Japan's Do Hiemon Box is a new walk-in personal cooling booth that chills the body to 15°C inside, with 5°C airflow directed at the head and neck. Priced at ¥1.5 million (~$9,230), it's now on sale for businesses across Japan.
