In 2017 Sarvekshak became the 1st ship of Indian Navy ever to deploy solar power. It has innovatively deployed the zero-maintenance solar power system, capable of generating 5.4 kW electricity and replacing the ship’s traditional 4.4 kW emergency diesel alternator.[12] The installation cost was around Rs. 19 lakh and the generation cost is Rs. 12 per kv per hour. The estimated savings for a lifespan of about 15 years is around Rs. 1 crore. The current diesel generator consumes a litre of diesel to produce five units of electricity. Captain Rajesh Bargoti, the commanding officer of the ship, said It took about six months to put the entire system in place. We are now using solar energy for lights and a couple of air conditioners.'[13] The estimated profit generated in a ship service life of 25 years is Rs 2.7 crore in this small project alone. "Even if the system is used for 25 days in one year, the system can repay its cost in less than 10 years while protecting the nature," the Navy said.

Indian Navy claimed that the 300-Watt panels will generate about 5.4 kW solar power system, and avoid around 165 kg of carbon a day, "So in its 25 years life the total carbon saved is around 15 lakhs kg and 5.75 lakh litres of diesel by this innovation" [14][15] Noting that the world is looking for clean, renewable sources of energy in order to protect and reduce the harm caused to the environment, the Navy said the deterioration of the environment is highly correlated to the production and usage of fossil-based fuels worldwide. The Navy said it has created a new mechanism to encourage the utilization and development of renewable energy resources.[16]

In 2006 Parakala contested the for the Graduates constituency of East and West Godavari Districts of the newly constituted Legislative Council of the state. He polled about 12,000 first preference votes but narrowly missed to make it to the second round in the single transferable preferential voting system. That was the fourth electoral defeat of Parakala. That election also led to Parakala breaking away from BJP. Parakala claimed that there was an informal understanding between him and the party leadership that he would contest as an independent candidate as the election was not fought on party symbols. This was a tactical move necessary to attract voters who were antagonistic to BJP among the educated sections. He claimed that the party reneged on the agreement and put up an official candidate. Parakala resigned from BJP and went ahead with the campaign. In the event the official BJP candidate did not poll more than 200 votes while Parakala polled over 12,000 first preference votes.

nishkriya aur sakriya RFID system ka istemaal sadak ke baahar ke khelon mein hota hai jaise oriyenatiaring, endyooro heyar end haaunds resing. chaalakon par ek traansapondar laga hota hai, aamtaur par unke haath par. jab ve ek laip poora karte hain to ve svaaip karte hain ya riseevar ko chhoote hain jo ek computer se juda hota hai aur unke laip samay ko darj karta hai. kaaseemo group limited aisi pranaali bechata hai, jaisa ki sveedan ka SportIdent. RFID ko kai bharti agencyon dvaara anukoolit kiya ja raha hai jinme unki arhak prakriya ke roop mein ek PET hai (fijikl endyoreins test), vishesh roop se un maamalon mein jahaan ummeedavaaron ki sankhya laakhon mein ho (bhaarateeya railway bharti prabhaag, police aur bijli kshetr). ek bhaarateeya software company, software aautasorsing sarvises ne is pranaali ko pehli baar UHF taig ka upayog karte hue isi uddeshya ke liye sateek banaaya hai aur ve pratidin 30,000 se jyaada ummeedavaaron ko chhaantane mein saksham hain.

kuchh pranaaliyon mein yadi digital deta ka ek bhaag lupt ho jaae ya galat tareeke se vyavahrut hon, to sambandhit deta ke vishaal khandon ka arth poori tarah se badal sakta hai. kyonki kleef ifekt ke kaaran, upayogakartaaon ke liye bataana mushkil hai ki koi vishisht system vifalta ke kagaar par sahi tha ya fir vah asafal hone se pehle bahut adhik shor ko sahan kar sakta hai ya naheen.
