Quote of the Day
The technology is based on a specially designed molecule of carbon, hydrogen and nitrogen that changes shape when it comes into contact with sunlight.
It shape-shifts into an ‘energy-rich isomer’ – a molecule made up of the same atoms but arranged together in a different way. The isomer can then be stored in liquid form for later use when needed, such as at night or in the depths of winter.
A catalyst releases the saved energy as heat while returning the molecule to its original shape, ready to be used again.
Over the years, researchers have refined the system to the point that it is now possible to store the energy for an incredible 18 years.
The Swedish researchers sent their unique molecule, loaded with solar energy, to colleagues at Shanghai Jiao Tong University. There the energy was released and converted into electricity using the generator they had developed.
Essentially, Swedish sunshine was sent to the other side of the world and converted into electricity in China.

That’s wild!
It was also in late 2022 and I have been unable to find any news on it since them.
I’m a bit skeptical because thermal to electrical efficiencies are, at best, something on the order of 40%.
