I was speaking to someone at a meeting this weekend about technologies and he was discussing a new product he is trying to get involved with to sell. It is some kinda modification to Nickel–iron battery technology that produces energy for 10 years. The cost saving appear to be around 70% over those 10 years.
Does anyone know more about this? Or had experience with this? I really really would love to give up my reliance in Eskom.
