Gadgets: Mummy wrap

[dracodraconis]

A new Zealand company has developed a shirt, dubbed MummyWrap, that it promises to protect fetuses from electromagnetic fields, such as those associated with cell phones.Bear in mind that there is no evidence that the EM fields to which we are all typically exposed represents any real risk to a fetus. The shirt contains copper wire embedded in the material. The maker claims, despite evidence to the contrary, that the shirt will protect against EM fields generated by high-voltage power lines.

Pity's sake. For an EM shield, the wrap needs to go all the way around. Faraday would be annoyed.

Yep, you caught on of the BIG problems... a Faraday cage must completely enclose what is being protected. Basic EM theory, which most people lack.
