If every household has its own power supply in the future, the current "power grid" is not environmentally friendly and the power is too small, only 10% of the power used rate. We can reuse the ropeway and in the future everyone will only need Doraemon’s bamboo dragonfly to travel. How healthy and interesting will our future world be? But we must not learn from the United States. . . Turn Americans into "oily people", "oily people" and bamboo dragonflies cannot take you to fly. . . Most of our life are "resource abuse and waste of resources" now!
如果未來每家都供電自主，因為現在的「電網」不環保，功率太小，只有10%的功率。我們再利用索道和未來每個人出行就只需要哆啦A夢的竹蜻蜓，我們未來世界會多麼健康有趣？但我們絕對不能學習美國。。。把美國人變成「油態人」（猶太人），「油態人」竹蜻蜓不能帶你飛翔。。。我們現在大部份都是「資源濫用和資源浪費」！
