A woman battling illness has invented an energy sacing device.  Tanya Ewing,38, of Perth, says her invention, Ewgeco, shows people jow much gas, electricity and water they are consuming.

 Tanya has battled Lyme disease for seven years, a condition which brings about both physical and neurological difficulties. 

She said utility meters hidden in cupboards or garages were difficult to read.  She already has orders for her product.
