  Those events are but the latest examples of an essential truism: If America is to secure its future, it must control its own technological destiny. This means that it no longer can outsource its technological development to countries that increasingly appear to be adversaries. Instead, it must rebuild its domestic innovation and production base. While Silicon Valley and Boston remain the envy of the global technology world, America is also fortunate that this need for a national response has come to the fore just as technological centers in what Intel CEO Pat Gelsinger calls the “Silicon Heartland” are reaching prominence. Gelsinger’s firm recently put this concept to work by investing $20 billion in a chip manufacturing facility in Columbus, Ohio. Another town emerging as a potential technology hub is Syracuse, N.Y., where Boise, Idaho-based Micron has announced a $100 billion investment in a mega-chip facility — the largest single investment in the state’s history.

  But this approach required a lot of chemical explosives and was largely abandoned because of safety concerns." Turning explosive energy into electricity is not easy , according to a Beijing-based researcher not involved in Xiaoyuan's study, who spoke to SCMP on the basis of anonymity.  "Zhang's team was able to achieve extremely high speeds and temperatures at the same time," said the researcher. Such explosions are very challenging to manage , and the researcher suggested that society would profit from taming this extreme method of energy production.
