A tiny device attached to a mobile phone may give some little breeze. However, to claim it will be highly effective in India's scorching summer heat is highly questionable! We are going to sweat buckets anyway.
Have you bought it? If not, on what basis are you stating "one can instantly get rid of scorching heat by having air."?
You also talk about using handheld fans and about this exercise being curtailed. Well, just don't buy the new gimmicky gadget and stick to traditional cooling tools!
(A request as per a thread suggestion I had made some months ago - please shorten the titles of your threads. They are needlessly far too lengthy & off-putting.)
When people come at you with their worst, you should come at them with your best (advice given to Selena Gomez by her mother, quoted in Time magazine.)
When you buy a phone more than Rs. 8k, please use genuine charger or battery. You may find cheap and attractive product but not all are good quality, connecting USB with your phone can have many bad affect to your phone. So, check it out properly, what you are attaching is quality enough to match with your phone, else you can lose your valuable mobile phone.
To give a simple example, do you know in that most parts of Tamil Nadu, people lock up their houses, and sleep comfortably just outside their houses on cots, just about enjoying the natural breeze and the natural environment. In fact, they end up saving a huge amount of electricity.,
We make the iddli and dosa dough with modern mixie machines. However, in hundreds of villages, this process is still done by human input, and also, very happily. Ditto for grinding any input required for cooking.
So, we need not worry about any consequence in this regard. It is but natural that science and technology will advance even further. But the natural alternatives will also continue to exist, and this depends hugely on a variety of mind-sets of people.
After a few years, when I wanted for my relative, I could not get it. But later, I saw the availability of USB fans in online portals. The present one is an extension of that.
I concur that though not very much durable, these are some conveniences and come to help us in need. Contextually I may add that we had also bought a small 4" TV working on battery, for our sun during his childhood. Unfortunately most such innovations are all coming mostly from Chinese/Korean manufacturers first.
Coming to the USB enabled fans, I have never used it. I don't know how much air it will supply and is there any way to increase and decrease the speed. However, these are good developments and technology is bringing many useful comforts to the mankind. But the original and natural appliances provided by nature can't be replaced by any of these items.
