The plane parked outside the airport looks more like a giant exotic insect or maybe an outsized toy. When it'€™s in flight, there'€™s no roar of engines. It'€™s strangely quiet. And as it crisscrosses the US, the spindly plane doesn'€™t use a drop of fuel. Day, and even night, it flies on the power of the sun.

Your comments:

I'€™m glad I live in the era of technological development. What will be next? I'€™ve learned that there is already untested technology that will enable us to save a huge amount of energy.

With the population increasing to the extent that we worry that food resources are insufficient, it is deemed necessary to apply new technology within this lifetime. Means to supplant the use of oil as fuel is the most urgent.

The world'€™s governments need many new young leaders who have broader visions of the future. I look forward to it. May God bless all those who have that kind of vision.
