MIT - making big liquid batteries for Electric grids?
There’s one major drawback to most proposed renewable-energy sources: their variability. The sun doesn’t shine at night, the wind doesn’t always blow, and tides, waves and currents fluctuate. Even in conventional systems sometimes load vary, sometimes there will be a peak load, sometimes load on the grid will be less. A large battery storage can save fuel . But there is no such a storage system for electricity on large scale. That’s why many researchers have been pursuing ways of storing the power generated by the sources(non-convetional and conventional) so that it can be used when it’s needed.

Who are Best/Worst in Fight against Poverty ?
Over one billion people – a sixth of humanity - don’t have enough to eat. Almost a third of the world’s children are growing up malnourished. This is perhaps one of the most shameful achievements of recent history, since there is no good reason for anyone to go hungry in today’s world.
In this scenario, it is required to assess how governments are performing in their fight against poverty..
