Ray needs electricity

Yesterday, Ray from the U.S.A. has seen this video online:

And afterwards, he wrote me this email:

Hello Niklas:

I saw your video with the power strip. How would a person acquire one? Does it work for 120 volts AC? Can you connect a series of power strips to the free plugs? Does it burn out? How long does it last? Does it work with heavy appliances?

You stated that you can make one out of common household goods. Do you have a schematic or plans? Do you have any more information? Is it UL approved?

Please let me know,

Thanks,
