 So you go deep dive after you found out the first issue that is inconvenient to use. It's not enough You need to go and check why is it continuing to use what is happening in the city? Avnash came about this Mr. Whippin was a very ardent enthusiast and he had two types of solar always in his house in Bombay So I would like you to tell us how this user was so passionate and what are the type of things he was Doing and what are the insight he gave to you? So actually the whole project changes when I meet this guy this guy using these solar cookers in his Balcony since like 15 years My perception about solar cooker is entirely changed then because he can use the solar cooker. Why not others? This man actually got the box type and he has the parabola also these two work phenomenally Well, you all know the best technologies have come into this Then you all know the procedure you can't really do inline cooking like Avnash was saying that you've add things in the middle And then you open you lose a lot of heat look at that lady She's making grotes on that parabolic cooker very hot and then look at a posture look at the issues multiple aspects were considered When I told you about the comprehension I also mentioned to you that you look at the dichronic and synchronic analysis You look at all solar cooking devices available in the market and see the problems and analysis Now coming back to Avnash's focus. He said Today most of the people are living in flats have serious problems in Multiple ways like drying pulses as well as cooking who are finding it very very inconvenient So looking at that inconvenience as a focus and these high-rise buildings have very good sun coming on one of your south side windows You have a lot of sun coming in and you can really use this very effectively So we identified all the key, you know aspects of Convenience the space The box is so big they said Karakenge and they keep the box on the attic and then you can't bring it down You need your you know husband or somebody in the house to bring the thing down And so we're used to how you stare the sizes in issue then for example you have Issues of saving of fuel some people generally want to save fuel by using solar over But we're not able to do it because of the Incalvilliance of taking it to the balcony and going to the terrace Perception about solar cooking is that it's cumbersome. It takes a long time and it is away from you So these are all the local issues which came up and you will see how you know we solved all that we Comprehended we found out all the aspects of various types of ovens How does the panel cooker work again concentrated reflection on to the vessel And absorption of the vessel itself. So here we go with our traditional box type cooker It's around five to six thousand and you get a two thousand to eight. So you spend around four thousand bucks on this So what should be your? Comprehension here. I must make a cooker which is less than this right every time you do a new design. It has to be Cheaper and better than the earlier one and it should use the best of technologies Should use the best of materials and you should have everything But it should be cheaper than the earlier one and this example is very clear from the mobile phones you use to the laptops You use every day Every time you buy a laptop within six months. It is two times better And you know 30 to 40 percent cheaper. You're noticing this so this is a very critical factor for us in design that you need to work on base and methods where you can build that type of capability of reducing cost drastically So here we are saying of it's six thousand and we should be able to reduce it to four thousand to three thousand if possible So that the thing can become popular
