cooling process rigid
2014/12/1
The puzzle pieces of tectonic plates that make up the outer layer of the earth are not rigid and don't fit together as nicely as we were taught in high school.
Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing power ...
加拿大启用全球首座清洁煤电厂（图）
加拿大 全球首座清洁煤电厂
2014/10/10
全球首座能够捕获自身二氧化碳气体排放的商用火力发电厂日前在加拿大正式启用。研究人员认为，这对于“清洁燃煤”技术的发展具有里程碑式的意义。
萨斯喀彻温省的“边界大坝”工程，旨在每年捕捉并向Cenovus能源石油公司出售约100万吨二氧化碳气体（占其经过改装的动力设备的二氧化碳排放量的90%），后者将把这些压缩气体通过管道打入地下深处从而获得抢手的地下原油。与此同时，未售出的气体则会转给Aquist...

美国科学家 预测磁铁 无线制冷器
2014/7/30
或许有一天，你家的冰箱可以用磁铁来作“制冷剂”。美国麻省理工学院（MIT）科学家近日发展了热电学中描述电子传输的方程，用于描述磁振子传输，发现如果处在有差异的磁场中，磁振子可能会从磁铁一端运动到另一端，带走热量而产生制冷效果。相关论文发表在最近的《物理评论快报》上。
