“煤油灯留着用得上”整栋房子一片沉寂,电灯不亮,冰箱停工。这是2012年7月31日的傍晚,当我回到加尔各答附近的小城桑地尼克坦的住处,我知道,又停电了。最要命的是,两台家用不间断电源(UPS)都无法启动。这种电源的逆变器电池需要按月添加蒸馏水,才能实现最大程度的化学蓄能。由于此前忘记加水,现在电池早就耗光了。 “Kerosene lamp keep using” The whole house quiet, light does not shine, the refrigerator downtime. This is the evening of July 31, 2012. When I returned to the residence of Sandiniktan in a small town near Kolkata, I knew that there was a blackout again. The most terrible is that two home uninterruptible power supply (UPS) can not start. This type of power inverter battery requires monthly addition of distilled water for maximum chemical storage. As previously forgotten to add water, and now the battery ran out of time.
