Really cool development that will be most valuable, even for manufacturing more solar panels, just from the sun, reducing the carbon footprint of rolling out solar energy itself.
Further, a plant like this could have a negative carbon footprint, if it is used also for high temperature disposal of plastic waste, converting it completely including all toxic fumes to harmless (maybe even useful) solid raw carbon, similar to that used in high strength materials.
Finally, as mentioned in the article, if there are possibilities in using it for Hydrogen production, then this could be the bridge between hydrogen power and solar power, giving hydrogen power also a truly zero carbon footprint, as this could remove the dependence of hydrogen power from any requirement to use conventional high carbon power sources in its production.
