What about the dendrite problem ?18 years ago the original research on the Zinc-air battery was to solve the dendrite problem, which was long standing and the reason no rechargeable battery was on the market. Three years ago the company anounced that the dendrite problem was solved and they where ready to go into production on a mass scale. The company then found that manufacturing costs of their first successfull regenerative plate was very expensive. It was so expensive that they decided not to product that plate on a mass basis. Developement of the carbon based, low cost, regenerative plate was started and the first, test plats manufactured in house was completed 1 year ago. Testing since that time has been done with no test results given. We are still waiting.
The battery to be installed in Surrey is a smaller and older designed to the 4 battery's to be manufactured in 2021. We have not been told if the Surrey battery has the new or old design regenerative plates. The Surrey battery is to be delivered to the Surrey site at the end of Dec. 2020. This is a agreed delivery date and could be changed if the Surrey house project is not ready.
This is our present sit and wait situation. We need to be patient.
GOOD LUCK TO ALL INVESTORS.
