The plague caused the accidental discovery of gravity. The better off were able to leave the city (socially distance) and return when it passed.I think this breakthrough will make a difference, it is similar to other lithium sulphur battery chemistries that are approaching production and would most likely be incorporated into them. We could see this used in batteries in a few years and if it works as promised, it will make a huge difference in RV's, grid storage and many other applications including aviation.

An accidental discovery could change the world
A surprise discovery by Drexel University scientists could unlock an elusive technology: lithium-sulfur batteries.www.freethink.com
Lithium-sulfur batteries can be cheaper to produce and up to three times more energy-dense than lithium-ion batteries.
But what they found instead was something incredible: a chemical phase of sulfur that basically stops battery degradation! They were so shocked by this discovery that they had to check 100 times to ensure they weren’t misreading it.
This chemical phase is known as monoclinic gamma-phase sulfur but had only ever been observed in the lab at high temperatures — upwards of 95°C (203°F). This is the first time it has been seen at room temperature.
In the battery, this phase completely stops the reaction that creates polysulfides. This was so effective that the scientists sent the battery through 4,000 charge cycles without a drop in capacity, meaning it lasts at least twice as long as lithium-ion.
It is also worth noting that their battery was three times as energy-dense as lithium-ion and could charge just as fast!
These batteries will weigh a third of the equivalent lithium-ion batteries and have twice their lifespan.
To say this is a remarkable discovery is a massive understatement. But this new phase of sulfur also has other benefits, like reducing battery expansion and increased safety margins. In other words, this battery has all of the hallmarks of the ultimate mass-market battery, and these scientists found it purely by accident.
That means much faster, more efficient EVs with ranges of thousands miles will be commercially viable at a similar cost to today’s EVs. What’s more, they would actually still be useful in 10 years time, dramatically reducing waste and increasing the rate of EV adoption.
Furthermore, short-haul flights, cargo vessels, and passenger ferries will have a technology that will allow them to go fully electric. The weight-saving, long life, and competitive price will mean these sectors can finally achieve their low-carbon goals.
In short, lithium-sulfur batteries could allow a huge range of activities to go electric, making net-zero emissions far more feasible.

That Congo strain they pursued had 7% THC and just over 1% THCV.
No sense in putting a Bic lighter next to that top cola.
Nice!
If ye be addressing me laddie boy,
Soon they'll be so small we'll inject them to treat our illnesses..but not in time for us, dear reader.
Some say they are already in the vaccines...
I wish.Some say they are already in the vaccines...
