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.
