Tell us about yourself!
For something really creepy, turn the image upside down (so the head is right way up).Upside down eyes and mouths always look weird.
No it isn't, this IS fun!
I wouldn't say it is "laughable" to say it is efficient... if you have an unused 12V solar panel laying around, use that instead of, or in conjuntion with a battery. Use the sun to do the work. THAT'S efficient.
True. It is inefficient compared to a refrigeration unit. And obviously solar would be better being used to power a conventional dehumidifier.However, since i began using Peltiers around a quarter century ago, their prices are now maybe 2% what they used to cost. "laughable" was what i took exception to. Who knows... tomorrow all refrigerant gases may be banned as environmentally unacceptable. And Peltier devices could be mass produced to fill the gap, making them cost efficient.
Use a solar panel / battery / inverter. Panel charges battery. Inverter changes battery dc to your regions ac supply. Some initial outlay, but then free for life of solar panel or your dehumidifier. I live in tropical north Australia... it works fine.
