Every system like yours works to flatten the prices, but it looks like a pretty big swing between peak and off peak pricing today, so it'll probably be a while before flat pricing again.
I am a staunch DIY serial entrepreneur techie that has used my grey goo to build and sell a few companies and my time now is spent similar to yours although using a different application of physics. I too am motivated, just as you are, in my efforts to apply what I know to further reduce my energy costs which will not stop rising for quite some time.
You really made my day with this post and I hope we can find more folks like ourselves from your share because in time 'dogfooding' new ideas at home will lead to new applicable discoveries for all.
Stay Healthy!
