· A mechanically-triggered multi-junction photocell has been successfully developed by the United States’ National Laboratory for Sandy, with a photoelectric conversion efficiency of 31% (only 3% of photocells currently used in computers). The laboratory predicts that solar cells will be shipped to the United States within 10 to 20 years. Provide a lot of electricity. · The sales volume of frozen beef in the Hong Kong market has increased, and the consumption is quite large. The main reason is that there are more new openings in hotpot restaurants in the four seasons, and diners tend to prefer beef with half weight when eating hotpots. · Japanese scientist Sang Yukihide proposes a solution using solar energy
