car solar fan "Auto cool solar powered car Fan" Question for dogs?
http://www.progalu.com/453-auto-cool-solar-powered-car-fan Does anyone have any experience with this product? If so, do they really keep the car cooler than if they were to have the windows open? I'm asking this as I travel frequently with my dogs, and there will be times where I have to go to a store for 10-15 minutes. Not long, but I want to make sure they are comfortable in the car. I was thinking of buying two of these and then string a bunch of cold-packs together and keep them in a refrigerator until it lay on the seat when I go in inside.
Of the 76 reviews from amazon.com, 59 only gave a star! http://www.amazon.com/Auto-Solar-2dPowered-Ventilation-System-Black/product-reviews/B000QGGY9E/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 Even among those who gave him four stars, says that to work properly, the car must have installed a sunshade on the windshield! I have a puppy buyer that you have installed really high quality umbrellas in the windows of the car except the windshield as I remember, and with the door open to start, if you go somewhere for a visit, easily can leave their dogs in the car for hours and I know first hand that your car is actually less than warm temperature. So my advice is to first install parasols good at least in all the windows back and see how much you think it helps, before bothering with the purchase of something like this.
I want to go to the field of photovoltaic design in some years after the economy gets better and I have some more experience as a regular electrical designer. At now I understand everything and spec transformers after the electricity company in commercial and residential buildings. Regarding the job descriptions, all the ads I saw were rather vague. They want some solar experience, a BSEE or equivalent experience, a background power / system design, etc. The fact is that PV is so much a niche sector that I've never taken lessons at school even talk about it (even with the 3-phase power, we had only weeks to explain it) and the information there is rare. I think certification NABCEP, but what else would benefit?
It seems to me that is oriented towards NABCEP installer certification rather than design, but they would probably teach the NEC requirements and familiarize yourself with the specialty products available. You could study the documentation of manufacturer photovoltaic and contact some of them to see if they have information not on their websites. Go to shows and fairs Energy and talk to suppliers. Attend seminars set up by suppliers. Keep looking for the kind of trade magazine Web sites and subscribe to related trade magazines print that you can find.

Solar Powered Home System – Easy Way To Have a Solar Powered
How can you make a solar cell using blueberry juice trapped between the glass coated with titanium?
There was a kit available but I can not find it now. Is there a special way the glass must be (de-magnitized, anti-static)? My chemistry is so rusty I do not remember how it works. I posted this question on chemistry, but it was not known. Thank you,
