SUMMARY

The discussion centers around the effectiveness of the "Extreme Power Saver," which claims to save 35% on electricity bills. Participants express skepticism, citing historical context where similar devices, based on outdated NASA technology, have been proven ineffective. The consensus is that such devices often degrade performance rather than enhance it. Additionally, the importance of understanding power factor correction is emphasized, particularly for industrial applications where penalties may apply.

PREREQUISITES
  • Understanding of power factor correction and its implications.
  • Familiarity with electrical circuits and their components.
  • Knowledge of how electricity meters function in residential versus industrial settings.
  • Awareness of historical context regarding energy-saving devices and their claims.
NEXT STEPS
  • Research "Power Factor Correction" and its relevance to energy savings.
  • Investigate the workings of electricity meters and their impact on billing.
  • Explore the history of energy-saving technologies and their effectiveness.
  • Examine case studies on the performance of similar devices in real-world applications.
USEFUL FOR

This discussion is beneficial for electrical engineers, energy efficiency advocates, and consumers considering energy-saving devices, particularly those interested in understanding the validity of claims made by such products.

I'm planning to buy an "extremepower saver" but I'm wondering if it's really effective? It claims that said device saves 35% electricity.

Please share your thouhgts or experiences.

If this is the technology I think it is, it's a total scam.
In the 70's, a circuit came out of NASA to decrease the waste heat on grossly oversized motors. It found an application in the clothes industry, where the motors ran constantly, but the load was only occassional. Ta-da, the 30%+ myth was born.

The circuit kept being "reinvented" with microprocessors, etc. Of course the inventors would present this miricle technology to the appliance manufacturers (to managament, of course), and as a young engineer, I got my turn to test it and demonstrate that contrary to the invenor's opinion, it substantially degraded to performance of any near optimal design.

Funny enough, we kept a file on these attempts over the years. It had all the test results and consistent failures.

PS, what's in the box? Well, it's usually been a light dimmer circuit with some means to control the phase angle that it switches on.

There is no information on the product at that link! You can't even buy it there. So in truth it's impossible to comment on it one way or another.

However I recommend you read up on "Power factor correction" just in case that's how they claim it works. You also need to check how your electricity meter works because in many countries there is no cost penalty if appliances in your home have a poor factor. So improving the power factor won't save any money.

Power factor correction is only an issue for factories and offices that consume a lot of power and are fitted with meters that penalise you if you have a poor power factor.
