　　Allen School of Computer Wholesale pure sine wave inverter Manufacturers Science & Engineering have developed a new cell phone that doesn’t need a bulky and dangerous battery to power it.5 microwatts of power to operate, which is equated to negligible.During a call, the cell phone uses vibrations from the microphone to encode speech pattern in ambient signals for sending voice data. Existing mobile phones have a complicated step of converting analogue signals into digital ones, which is understandable by computers but requires a lot of power to do that. The reason behind the extremely low power consumption is because the cell phone uses ambient wireless signals as its primary way to communicate with the other device. In fact, it requires 3. While all of this is amazing, it still is unbelievable to see a device do conventional mobile telephony while drawing zero power. However, scientists have come up with a way to eliminate the battery from the smartphone, completely.Well, zero power doesn’t mean absolutely powerless. The cell phone can transmit speech data and receive incoming speech data. The prototype device shown in the demo had a button to switch between transmitting as well receiving modes.

　　"You could imagine in the future that all cell towers or Wi-Fi routers could come with our base station technology embedded in it, and if every house has a Wi-Fi router in it, you could get battery-free cell phone coverage everywhere," said Vamsi Talla, a research associate at UW. While various parameters like displays and cameras have gained incremental leaps, one area still hasn’t seen any considerable progress – their power source.(Source). To compensate the increasingly powerful specifications, manufacturers are still relying on a dangerous combo of lithium and ion, a point proved by the infamous Samsung Galaxy Note 7.The team designed a separate base station to transmit as well as receive radio signals, which they say could be integrated with existing cellular network infrastructure or home Wi-Fi networks. Its creators claim that it consumes almost zero power, a feat that has been achieved by using existing components from the world of wireless communication.A group of eggheads from the Paul G.

　　"We cannot have different tariff for Mumbai and rest of Maharashtra. The tariff levied on Maharashtra consumers should be the same for Mumbai consumers. We have refused to reduce our tariff for Mumbai as it will affect other consumers across the state," said chairman and MD of MSEDCL Sanjeev Kumar. Currently, there is huge difference in the tariffs in the city and suburban area as different companies supply power at different places. While BEST has maximum number of its consumers in the island city, Tata, MSEDCL and Reliance remain in demand in the eastern and western suburbs.A few months ago, energy minister Chandrashekhar Bawankule had announced of plans to bring some parity in the electricity tariff for the city consumers on the lines of Delhi.
