In what scientists are calling a "giant leap" toward clean energy, researchers at MIT have developed a way to store solar energy for use when the sun does not shine, paving the way to large-scale solar power.Sunlight has the greatest potential of any power source to solve the world's energy problems.
In one hour, enough sunlight strikes the Earth to provide the entire planet's energy needs for one year.
Until now, however, solar power has been a daytime-only energy source, because storing extra solar energy for later use is both expensive and inefficient.

A new poll has found that only 5% of people think the new, compulsory home information packs have delivered benefits. But, says Jim Pickard, the government always claimed Hips were necessary to meet the EU directive demanding that home sellers must produce energy performance certificates (EPCs) - which form part of the new packs. However, in northern Ireland, as of the start of this month, EPCs have been introduced; without Hips.
Step forward, Yvette Ballsup. Another triumph for the Ballsup family.

"When electricity, whether from photovoltaic cell, wind turbine or other sources, runs through the electrode, the cobalt and phosphate form a thin film on the electrode and oxygen gas is produced."
Uh?! There is nothing new here, this is straight forward electolysis water using a couple of carbon electrodes and an electric current.
And anyway, if you have split the oxygen from water, all that is left is ... hydrogen.
So what is this other catalyst doing?
"Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can copy the water-splitting reaction that occurs during photosynthesis."
If you have a catalyst that produces hydrogen from water when you pass an electric current through it all you have left is ... oxygen.
The only new thing I can see in this article is that it is recombined in a fuel cell to produce energy at night. In short, it is a battery.
