The Tiny Star Explosions Powering Moore’s Law

Cars That Think

Supernova explosions, the catastrophic self-destruction of certain types of worn-out stars, are intimately tied to life on Earth because they are the birthplaces of heavy elements across the universe. Mirrors could not achieve the same focusing precision as the previous lens-plus-water combination.

Revealed: General Motors battery guru explains why lithium – not hydrogen – is central to our EV future

EV Central

When it comes to ubiquity, of course, we’re constantly reminded that hydrogen is the most abundant element in the universe, and we know that cars with electric motors can be powered by onboard hydrogen-fed power stations. So if you think about, if you wanted to make a cake, you know, you can go to the store and you can buy a box of cake mix.

Uppsala team develops composite polymer dots for efficient, stable H2 production from water and sunlight

Green Car Congress

Researchers at Uppsala University have developed photocatalytic composite polymer nanoparticles (“polymer dots”) that show promising performance and stability for the production of hydrogen from water and sunlight. Since polymer dots (Pdots) are so tiny, they are evenly distributed in water. —Liu et al.

Novel battery to extract and store energy from the salinity difference between seawater and river water could make significant contribution to renewable energy

Green Car Congress

Estimated extractable power (GW) from the difference of salinity in different countries, based on flow of river water emptying into the ocean. The large scale chemical energy stored as the salinity difference between seawater and freshwater is another renewable source which can be harvested. Credit: ACS, La Mantia et al.
