ジャパン・エネルギー・サミットに行ってきました！

水素で動く吸収式冷温水機や風力を使って燃料を削減するタンカーなど、素晴らしい技術がいっぱいです！

I went to the Japan Energy Summit & Exhibition! There were lots of great technologies on display, including a hydrogen-powered absorption water chiller and heater, and a tanker that uses wind power to reduce fuel consumption!
