But area for capturing the sun (looks the circle fresnel on the top), could be larger, to get more storage and more hour of use alfter sun goes out.

Would a similar idea works for home storage of electricity, being cheaper than bateries ?
Sure it would require a small turvine, to use the heat of sault to produce steam.
*The eutectic salt would not give back all that it had stored.
*Any heat loss of the stored energy would be an issue.
*There would be heat loss at the boiler heat exchanger.
*There would be losses across the turbo-generator.
*There would be losses at the cooling tower heat exchanger.
*There would be inefficiencies associated with the cooling tower fan
*Losses at any working fluid pumps.
I don't think you could beat the efficiency of existing battery technology.
