How can I shield electric field from a power cord?

According to TriField TF2, if the power cord touches a wooden desk, the desk inherits some of electric field.

I don't know a cheap effective way to shield electric field from a power cord.

Does anyone know?

I didn't know that this happened with wood, but have seen this happen with granite countertops.

I don't know a cheap effective way to shield electric field from a power cord.
Does anyone know?

Maybe not so cheap but could replace with a shielded cord available online, or place cord inside a long metal pipe. What about wrapping the cord with aluminum tape available from hardware stores - anyone know if this would help enough?

do not forget to ground the shielding ( avoid loops, follow the model of a tree with branches, the root being here the rod going into the garden ).

there is a type of exectical cable called " m.c. cable, (Metal Clad Cable)"  you can buy it at an electrical suply store, and you can buy lengths of it also. this type of cable is used in comercial applications.. it has a metal housing that protects the wire and is grounded when used with the corect conector,, you will have to connect your own plugs on it though!!

that looks good.
i'd prefer the type with aluminium armor.
no steel because that enchances elecrtrical field.
grounding the shield would solve this as it gets rid of all electrical fields from the wires, but possibly not well enough when too strong as a result of nearby steel.
