模仿自然帮助年轻的科学家赢得青年自然科学家奖。
如果说树叶是树木的太阳能面板，可收集太阳光进行树木生存所需的光合作用，那么为什么不模仿树木收集太阳能的方式供人类使用？
这正是居住在纽约长岛(Long Island, New York)的艾登•德威尔（Aidan Dwyer ）所做的。
他建立了一个“太阳树”原型，并将它与传统的平板太阳能集热器相比，发现他的“太阳树”原型生成的电力多50％以上。
德威尔13岁时就注意到冬季树枝相互交叉的形状。 他在一篇论文中写道：“当时我看到的形状说明，树形设计避免了受其他物体遮避的问题。”这篇论文帮助他在2011年赢得了由纽约市美国自然历史博物馆（American Museum of Natural History ）主办的青年自然科学家（Young Naturalist ）国家科技竞赛的一个奖项。
德威尔继续调整他的设计，以便更准确地测量电流和功率。他说，到目前为止，他的树形设计仍然优于平板太阳能集热器。
他已经提交了临时专利申请，以保护自己的研究，这已引起国际社会的关注，他说，这“可能将真正改变世界”。

Trees Show the Way to Capture Solar Power

Learn how mimicking nature helped a budding scientist win the Young Naturalist Award.
If leaves are the solar panels of trees — collecting sunlight for the photosynthesis the tree needs to survive — why not mimic them for collecting solar energy for human use?
That’s what Aidan Dwyer of Long Island, New York, did.
He built a prototype “solar tree” and compared it against conventional flat-panel solar collectors and found his tree design made 50 percent more electricity.
Dwyer was just 13 when the tangled branches of trees in winter caught his attention. “I saw patterns that showed that the tree design avoided the problem of shade from other objects,” he writes in the paper that helped him win an award in 2011 in the Young Naturalist national science competition sponsored by the American Museum of Natural History in New York City.
Dwyer continues to tweak his design to more accurately measure electrical current and power. So far, he says, his tree design continues to outperform flat panels.
He has filed a provisional patent application to protect his research, which has attracted international attention, and which, he says, “could actually change the world.”
