如今大多数人都是机不离手，因此出门在外必须要充满电才有安全感，解决手机电量问题除了随身携带充电宝外还可以租借共享充电宝，但目前共享充电宝的租 借费用并不便宜，尤其是景区和高消费场所，价格已经高达6/8元每小时，钱包难免会有些吃紧。 对于深圳市民来说，又多了一个户外充电的选择。近日，深圳街头具备无线充电功能的新型石墩引发网友热议。 这种新型石墩在普通石墩的基础上，加入了视频播放及无线充电功能，支持免费充电，辨识度极高。 根据网传视频，石墩带有电子屏幕，点击屏幕可观看视频，且屏幕下方位置标注了"免费无线充电"几个字。 市民只要将手机放置在石墩上的指定充电位置，手机很快就进入无线充电模式。 按照运营方的说法，带屏幕的石墩是用作广告投放的，效果很好，接下来，他们计划进驻万达广场，并将该项目逐步推广至全国。 石墩显示屏和线路好密封好，可防水防雨，使用的是低压12V电源，符合国家规定的安全电压标准，确保使用安全。 对于能充电的石墩，网友态度却大不同。 支持者认为，这是城市智能化与便民服务的创新结合，有助于缓解市民的"电量焦虑"，对依赖电子支付的群体具有实际价值。 反对者则认为，这是伪需求，实际意义不大，一来可能吸引人群滞 ...

搭载超导推进系统的电动飞机掠过江面，向远处飞去。 超导磁悬浮列车以时速1000公里平稳行驶，北京至上海只需一个多小时。 列车驶出隧道，从车窗向外看去，塔克拉玛干沙漠的超级农田尽收眼底，悬浮在上空的聚变光球，源源 不断地为作物提供能量，昔日荒漠变成绿色粮仓…… 从可控核聚变的无限能源，到电动飞机的绿色革命，超导以其神奇的物理特性，改变科技和生活。 可控核聚变 可控核聚变可以从根本上解决人类的能源问题，被许多国家列为未来能源的重要战略方向。基于超导磁 体的磁约束聚变技术最具工程化潜力，其核心特征是通过超导磁体产生的环形强磁场在真空腔内约束高 温等离子体，形成类似"磁笼"的约束环境。 想象一下，未来超导可能如何影响人类生活？ 晨光中，城市道路行驶的汽车，正通过地下的超导无线充电设备实时补能。 磁约束聚变装置内部存在着极端的温度环境：超导磁体需要低于零下200摄氏度的低温环境来维持超导 特性，而被束缚的氘氚等离子体却高达上亿摄氏度，这相当于将太阳装进冰箱，是当前最具挑战性的前 沿工程技术之一。近年来，高温超导材料和磁体技术快速发展，可在较高的温区产生远高于低温超导材 料的磁场，成为目前推动聚变装置发生变革性突破、实现 ...
