Shri  Akhil Kongara ( Research Scholar , IIT Madras )

================================== 

 Dear Friends,

 

Just read about your development of Zinc-Air Battery , through following news reports :

 

 IIT Madras researchers develop mechanically-rechargeable zinc-air batteries

 IIT Madras Researchers Develop Next-Generation Battery Technology That Could Revolutionise Electric Mobility

IIT-M Researchers Develop Made-in-India EV Batteries 3 Times Cheaper Than Li-ion Cells

 

Apart from other numerous advantages of Zn-Air battery, what excited me most was the intriguing reference to “ Mechanically Rechargeable “ feature

How exactly ?

Like a stationary Bicycle ( on a stand )- and connected to a Electric Generator - where a person can just keep “ pedalling “ to produce an electric current, which, in turn, will charge the “ Zn Cassette “ ?

 If yes, then you may be heralding a REVOLUTION of sorts !

Some 30 years ago, when Sam Pitroda introduced the concept of PCO ( Public Call Office ) – for millions of Indians who could not get / afford a telephone Landline at their homes – a MILLION PCOS sprung up on footpaths of every town in the country

 If Zn-Air Cassette can be recharged by a “ pedalling bicycle “  then I imagine a million unemployed youth can set themselves up as SELF EMPLOYED , and roam the streets of India, shouting :

“  BATTERY  RECHARGE  WALA “  !

 

I anxiously await your clarification / comments on what I envisage

Dear Mr. Hemen,


It was great talking to you over phone. I am attaching the details of our zinc-air battery below for your reference. 

 Thanks and regards,

Akhil

Details of zinc-air battery


Mechanically rechargeable zinc-air battery specifications

 

Total energy of battery built in our lab: 2.6 kWh

Total power: 40 W continuous (Work in progress to improve power)

Cell level specific energy: 400 Wh/kg

Mechanical recharging time: 5 minutes

Safety: Extremely safe. No scope for fire accidents

Lab scale cost: $ 100 per kWh

Lifetime: Need rigorous testing for estimation. Work in progress

 

Process of mechanical recharging: Zinc anodes will be available as plates which will be manually inserted in the battery. During discharge, zinc will be converted to zinc oxide. Upon completion of discharge, zinc oxide will be recovered from the battery and fresh zinc plates will be manually inserted. This process will take a maximum of 5 minutes to mechanically recharge an electric 2-wheeler battery.

 

Note: We have developed our own recharging station where we convert zinc oxide collected from battery back to zinc plates using renewable energy. This recharging stations can be installed anywhere like petrol bunks and even layman can operate the recharging station with some basic training. We envisage that the public find the business of installing recharging stations and providing zinc plates (fuel) to EVs to be economical which will be the key aspect for wide adoption of zinc-air technology.

 

We have future plans to scale-up the battery to 100 kWh by 2024.

Dear Taylor Scott - IKIN - My Time is Running Out !

 Fri 10-06-2022 12:22

To  :  beta@ikininc.com; taylorscott@ikininc.com

-------------------------------------------------------------

Dear Taylor Scott,

 

Just viewed your following interview on Cheddar News :

 

https://cheddar.com/media/check-out-the-worlds-first-hologram-accessory  /  19 May 2022  

also :

https://ikininc.com/discover-magazine-hopeful-scientists-bring-holograms-to-life/  }

 

-           Which reads :

 

=================================

 

Holo tech may never reach Star Wars levels, but devices like the RYZ (concept image above) promise to bring 3D displays to your smartphone. (RYZ Concept image, IKIN)

 

IKIN, a startup based in San Diego, is working to create three-dimensional displays through a new device that attaches to smartphones.

 

Known as the RYZ (pronounced “rise”), the accessory features a patented lens, explains founder and Chief Technology Officer Taylor Scott. To a viewer looking through the portal, full-color objects appear against the real-world background.

 

Leveraging advanced AI algorithms, the device keys in on a user’s eyes and other cues not only to simulate stereoscopic depth but also to merge the photons coming from the background environment with the light being projected to the user’s retinas. This “additive processing” allows the system to continuously adjust an image in real time to compensate for the brightness and color of objects behind the image, says Scott.

 

“We track the environment around you and use that light that’s coming toward your eyes already and add to it to create the image that we want,” Scott says, adding that the device can be used in broad daylight, unlike most goggle-based systems and stage productions.

 

Users can manipulate the high-resolution depth fields by touching the glasslike window, and multiple users can view different perspectives of the images depending on their position relative to the device.

 

Scott foresees a litany of applications for the tech, ranging from immersive video communications to advanced medical imaging techniques, such as brain scans and echocardiograms.

 

Software developers will be able to create content for the device, while the RYZ app will enable users to play games and convert their existing digital images and videos into depth fields. “We’re providing consumers the ability to take all of their memories and relive them in a hologram,” Scott says.

=================================== 

 

Is RYZ screen ( to be attached to my Smartphone ), already available ? If yes, from where can I buy one ?

 

I believe I would also need to download API software ( from where ? ) to be able to view as 3D Volumetric Hologram, my 63 year old Marriage Video on my mobile

 

Incidentally, on www.personal.ai , I have , over the past few months , posted my DIGITAL CONTENT of over 60 years ( from…www.hemenparekh.in ) and “ generated 82,496

MEMORY BLOCKS

 

 

I attach a SCREEN SHOT of a page of personal.ai

 

Is it CONCEIVABLE that my RYZ virual AVATAR can “  take all of their memories and relive them in a hologram  “  ?

 

 

Your affirmative answer could be the best gift for my forthcoming 89th birthday on 27 June !

 

With regards,

Hemen parekh

Dear Friends,

 

 

Just read your above-mentioned article in today’s Business Line

 

 

At one place , you write :

 

“  Dhundi village in Kheda district of Gujarat, formed the WORLD’s

 FIRST , Solar Irrigation Cooperative, Dhundi Saur Urja Utpadk

 Sahakari Mandli ( DSUUSMin 2016

 

   

   The Solar Energy provides, power to run irrigation pumps, water for

 farms, cattle, homes and income by selling the SURPLUS ENERGY to

 the Grids

 

 

 

In this context, you might want to look up my following earlier E-MAILS to our Cabinet Ministers :

      -----------------------------------------------------------------------

 

[ E ]      No Godfather for Rooftop Solar ? ………[ 01 June 2021 ]

 

Extract :

 

Dear Shri R K Singhji ( Minister for Power ) :

Ø    It is high time we stop limiting our SOLAR VISION HORIZON

      like a “ Frog  in the Well “

       

Ø    It is time to remember that the nomenclature : Roof Top Solar

      “, somehow ties us down to the words ROOF TOP , which is only

      just one of the  locations which can be used to harness Solar

      Energy

       

 Ã˜   Solar Energy can also be harvested at other locations on Earth,

      such as,

FARMS , DESERTS, LAKES, MOUNTAIN TOPS, HIGHWAYS , TRAIN TRACKS, etc.,

 or even through solar panels farms in  SPACE ( low earth orbits ?

 ), beaming electricity down to Earth-based receivers ( using micro-

 waves ? )

    

 Ã˜  We must break loose  from the narrowly defined, Roof-Top Solar

   / Land-based Solar and latch on to the all-encompassing concept

    of :

      

                SOLAR  ENERGY  TRADING INFRASTRUCTURE  ( SETI  )

 

 

Dear Shri Amitbhai Shah ,

 

 

You are the Minister for Cooperatives

 

Against our target of 40 GW of Rooftop Solar by March 2022, as of

 today ( mid May 2022 ), we have managed to achieve, a meagre 6

 GW !

 


To fulfil the commitment made by our PM , Shri Modiji at COP26, there

is only ONE WAY –  Sardar Patel Way !

 


Please , implement my suggestion to turn this entire system ( of

generation–distribution–sale of Solar Power ) into a :

 


 CO-OPERATIVE MOVEMENT

 

I urge you to REPLICATE the MIRACLE called AMUL
