Inventions wanted!

I haven't found out the cost of those fuse adapters yet but if they're reasonable I think I'm going to switch all of our old cars over to the new fuses with them.

30 years ago I had an idea for a device that would plug into electrical outlets and give an accumulated energy cost readout of appliances that would be plugged into it. I figured it'd be great for seeing how much a refrigerator or television costs to operate. Last year I saw something similar for sale at Menards.
