Salt Water System Could Generate Hydrogen

(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...

New mathematical model aids Big Bang supercomputer research

(PhysOrg.com) -- Scientists have made many discoveries about the origins of our 13 billion-year-old universe. But many scientific mysteries remain. What exactly happened during the Big Bang, when rapidly evolving physical ...

The environmental trade-offs of autonomous vehicles

Optimistic predictions expect reliable autonomous vehicles to be commercially available by 2030, at a time when mobility is undergoing a profound shift away from traditional modes of transportation and towards door-to-door ...

Investigating a thermal challenge for MOFs

To the naked eye, metal organic frameworks (MOFs) look a little like sand. But if you zoom in, you will see that each grain looks and acts more like a sponge—and serves a similar purpose. MOFs are used to absorb and hold ...

Lockdown emissions fall will have 'no effect' on climate

The unprecedented fall in greenhouse gas emissions from lockdowns during the pandemic will do "nothing" to slow climate change without a lasting switch from fossil fuels, an international team of researchers said Friday.

UK 'increasingly likely' to see +40C temperatures: study

Temperatures in Britain could exceed 40 degrees Celsius every three or four years by 2100 if greenhouse gas emissions continue unabated, research published Tuesday has found, as climate change increases the likelihood of ...
