100,000 Solar Powered LED lights float down the Sumida River
At the Tokyo Hotaru Festival, the sea of blue LED lights flowed past the Tokyo Sky Tree, a radio broadcast tower that was completed in 2011 and is now the second tallest structure in the world after the Burj Khalifa. The event, which took place just a day after the emergence of the amazing ‘supermoon’ on Saturday.
Dubbed “prayer stars,” the LEDs were provided by Panasonic, who claims that the balls, which were designed to light up upon contact with water, were 100% powered by solar energy. After illuminating a large stretch of the river, which also hosts a popular fireworks festival in the summer, the LEDs were all caught in a large net.
