ripulire l'inquinamento elettromagnetico
 

cercate phone dome e compu dome. io me li sono comprati.

vedete anche stetzer filter

Dubito possano avere effetto.

Per schermarsi dai campi elettromagnetici serve ben altro e, nel mondo attuale, è praticamente impossibile.

qualche bella ricerca sugli effetti dei campi elettromagnetici.

Conclusions
The purpose of this report was to assess the impact of Stetzer Filters on the electricity
supply in the home, in particular to look at its claims to reduce the “dirty electricity” in
the line voltage within the specified range of 4kHz to 100kHz. It is important to note that
these filters do not claim to reduce magnetic fields at any given frequency.
We conclude the following:
1) The Stetzer filter draws 0.9 amperes of reactive current on its own therefore
increasing the amount of current supplied to the home, increasing the burden on
the electricity supply and increasing ambient magnetic field levels in the house.
The amount of increase may be large or small depending on the number of filters
installed.
2) The Stetzer filter does not clean up line voltage harmonics. Nor does it help to
restore the current of a non-linear load back to a sinusoidal shape. The Stetzer
filter current is highly distorted containing harmonic content up to 10 kHz.
(Stetzer current harmonics are accentuated versions of the line voltage
harmonics.) Since Stetzer filter currents add vectorily to the other load currents in
the home, their distortion products (harmonics) are carried on the electricity
supply and add to the level of “dirty electricity” in the house.
3) The Stetzer filter is probably effective in attenuating high frequency (4kHz to 100
kHz) noise on the AC power lines although these components are small to begin
with. No assessment can be made concerning its effectiveness in suppressing
transient disturbances since these phenomena are random, infrequent events for
which we are unable to test.
The impact of installing one Stetzer filter on an outlet has no financial effect on the
homeowner since capacitive or inductive (reactive) loads are out of phase with the line
voltage and do not consume energy. Consumers only pay for resistive load currents that
are in phase with the line voltage. However, the electricity provider must generate the
additional current and carry it on the network. An example of this impact would be as
follows. In a community of 100,000 homes, if 25,000 homeowners decided to equip their
homes with 20 filters per household (20 x 0.9amperes), this would add a constant demand
on the network of 450,000 amperes reactive. In some situations, this could lead to the
requirements of additional transmission facilities (towers) and would translate to higher
magnetic field exposure in proximity to the towers.

qui dice che non hanno effetti.
