Stanford researchers develop a way to store solar energy more cost-effectively for use at night

solar energy storage

How electrolysis could produce hydrogen as a way to store renewable energy.

There isn’t a cost-effective way to store large-scale solar energy. But researchers at Stanford have developed a solution by using electrolysis to turn tanks of water and hydrogen into batteries. During the day, electricity from solar cells could be used to break apart water into hydrogen and oxygen. Recombining these gases would generate electricity for use at night.

Economic shift to the east revealed in global night light patterns

Night lights

How is light distribution of light across the planet changing over time?  Light produced by a society is closely correlated with its economic status.  Rich developed countries tend to be brighter at night than poor developing ones.

Driving Three Hours at Night as Bad as Driving Drunk

car accident

Two hours of motorway driving in the dark can affect performance so severely it is the same as having a couple of drinks.

Just three hours behind the wheel at night can make motorists drive as badly as if they were drunk, according to scientists.  Driver tiredness after a few hours has the same effect as being over the drink-driving limit, a study has revealed.

New Telescope To Attempt To Catalog Entire Night Sky

New Telescope To Attempt To Catalog Entire Night Sky 

The Large Synoptic Survey Telescope (LSST) is “a proposed ground-based 6.7 meter effective diameter (8.4 meter primary mirror), 10 square-degree-field telescope that will provide digital imaging of faint astronomical objects across the entire sky, night after night.” What’s that mean? Well, it means, if it’s built, we’ll have a telescope attempting to catalog the entire night sky into an absolutely massive 150 petabyte database. Awesome!

Full Disclosure Toilets

 Full Disclosure Toilets

When nature calls, sometimes it demands attention

Few people around the world choose to make a difference by adding fashion elements to their toilets. Those who manage to make a name for themselves, deserve our respect. Because it involves a moment of peak personal humility, we took time out of our busy routines to find toilets caught our attention. (Pics)
