energy server evolution

I've continued to evolve the energy server. It now uses Ajax techniques to improve dynamic data without traumatizing machines with slow connectivity. It's just neater and will be valuable when I add features such as real time graphs.
Now the web page gets loaded only once. Javascript in the page then asks for just the energy data from the web server every 2 seconds and then fills in all the places on the page with new data. The string of data is < 100 bytes.
It has been tested on Firefox 1.5 and IE6. Very old broswers might not show dynamic content.
