                                                 battery prices decline
                             2008: 1200 US$/KWh  2018: 108 US$/KWh
The forecast for all companies involved in the market is a further decline of prices in a similar Dimension for the next 10 years. At least 90%,so that in 2028 a 1 KWh battery storage will cost only 10 US$.

    A 1/10 of the actual lithium battery 1 KWh power delivery price would become  down to 2 US cent cheap !

How fast these energy storage devices can reach this claimed, filed 1997, endconsumer price level :

                                                                        25 US$/KWh ( > 15 years life)

I would invest in a Petafactory ( thinking loud)

0,1 up to 1,0 US$ cent/KWh for "e-storage" will change our "energy structure" like the wheel changed the society. !

                                         [0008] generated several times the power it consumes to operate

                                        how many times does a negative AC voltage back charge multiply
