核聚变神话

法国正急着要建造国际核聚变实验堆,据称该实验堆可以显示核聚变能够用作核电站的能源。因为核聚变可以提供无限和清洁的能源,所以国际核聚变实验堆通常被看作是解决全球变暖问题的长期解决方案。但是国际核聚变实验堆无法做到这样的事。

在我们今天用来产生核能的核裂变反应中,是把铀这样的重元素裂变成小的元素,而核聚变是把像氢这样的小元素结合在一起形成重元素(氦)。核裂变和核聚变都能产生巨大的能量。

一些政治领导人解释说太阳里发生的就是核聚变,而通过国际核聚变实验堆,我们可以控制这种反应。他们还经常补充说,因为聚变燃烧的是氢,而海水就含有氢,因为这是一种无穷无尽的能源来源。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
