China's Artificial Sun

China has set a record [记录] for creating the largest heat ever recorded. Scientists created temperatures of up to [最多为] 70,000,000ºC in an"artificial sun". The new record was for keeping the heat at atemperature that is five times hotter than the sun [比太阳热五倍]. It did this for more than 17 minutes. The extreme heat was created in a nuclear fusion reactor [核聚变反应堆]. The reactor is part ofthe Experimental Advanced Super-conducting Tokamak project (EAST). It reproduces the natural reactions that happen inside our sun and other stars.The scientists want to develop the artificial sun [人造太阳] to create a near-endless supply [近乎无限的供应] of clean energy. The EASTproject has cost China more than $950 billion. Total costs will run over $1trillion this year.
