Actual efficiency?

"While converting heat to electricity is inefficient, that loss can be overcome by the potential cost savings – storing heat is 50x to 100x cheaper than storing electricity, the researchers say."

actual numbers for that? missing. wonder why...

thermal solar already struggles to be competitive with PV and while electric heating is close to 100% efficient, the extraction would have to be an order of magnitude better than thermal solar
