PRODUCED ELECTRICITY FROM LEMON FOR POWER BANK

  I FRIENDS, WELCOME TO  TECH. TODAY IS AN EXPERIMENT BLOG. EARLIER WE PRODUCED ELECTRICITY FROM LEMON FOR POWER BANK. WE WOULD'VE CAME ACROSS THESE DURING SCHOOL DAYS, PRODUCING ELECTRICITY FROM TOMATOES, LEMONS AND POTATOES. BUT WHAT WE'RE GONNA DO TODAY IS TOTALLY DIFFERENT FROM THAT. WE'RE GONNA MAKE ELECTRICITY FROM MUD. FIRST WE NEED TO COLLECT SOME MUD. I'VE A CONTAINER HERE WITH ME. WE'RE GONNA COLLECT THIS MUD AND GONNA MAKE A BATTERY FROM IT.   SEE, THE MUD. WE'LL COLLECT IT.       WE'RE COLLECTING LITTLE EXTRA MUD BECAUSE WE'LL BE MAKING 4-5 CELLS. 

WILL COLLECT THIS CONTAINER FULLY AND THEN LEAVE. I'M TAKING SOME MUD FROM HERE. NO PROBS RIGHT??   SEE THIS, BLACK ONE.   WE'VE COLLECTED. GONNA MAKE FEW BATTERY CELLS, SO THAT'S WHY THIS MUCH. BYE! THE MUD WE COLLECTED IS HERE. NOW WE'RE GONNA LOAD THESE INTO THESE GLASSES. THESE GLASSES WILL BE CONVERTED INTO EACH BATTERY CELLS.   SO WE'LL FILL IT. WE'RE FILLING THE SECOND ONE.   WE'RE FILLING THE THIRD.   DOESN'T SMELL GOOD.   BUT I LIKE IT. SO WE'VE FILLED MUD IN 4 BEAKERS. WE'LL CONVERT THESE INTO EACH CELLS. TO CONVERT IT INTO CELLS, WE'LL INSERT COUPLE OF THINGS IN IT. A ZINC PLATE AND A CARBON STICK. FOR THAT WE'RE GONNA USE A BATTERY. 

WE'RE GONNA TAKE SOME USED BATTERIES FOR THIS. WE'RE ABOUT TO OPEN THIS OLD BATTERY. CAREFULLY PEEL OFF THE METAL SHEET ON ITS BODY.   AFTER OPENING IT, CELL IS HERE.   WE NEED TO REMOVE THIS PLASTIC COAT.   SO WE CAN REMOVE IT LIKE THIS.     THEN WE CAN REMOVE THIS RUBBER BUSH.   THIS IS ZINC. IT IS ANODE. THE STICK IN THE MIDDLE IS CARBON, CATHODE. SO WE'LL REMOVE THE CATHODE. WE CAN REMOVE IT EASILY WITH A PLIER. WE NEED TO TAKE ZINC. SO WE CAN CUT OFF THE BOTTOM.   WITH A BLADE, WE CAN SPLIT IN THE MIDDLE.   AFTER REMOVING IT, ZINC PLATE IS READY. WE CAN MOVE THIS ASIDE. THIS IS MANGANESE DIOXIDE. THIS IS WHAT PRODUCES ENERGY. 

THIS IS ZINC AND CARBON STICK. WE NEED TO PEEL 4 SETS LIKE THIS.   WE'LL SEE HOW WIRING IS DONE FOR IT. WE'RE STRIPPING COPPER WIRE ON CARBON STICK AND SIMILARLY ON ZINC PLATE. WE'RE PIERCED A HOLE IN PLATE. WE'LL INSERT WIRE AND TIGHTEN IT.   WE'RE GOING TO MAKE CELL. WE'VE TOOK THE BEAKER. NOW WE'LL INSERT ANODE & CATHODE IN IT. ANODE = CARBON STICK. INSERT IT. CATHODE = ZINC PLATE. INSERT IT.       NOW THIS BEAKER WHICH CONTAINS MUD IS CONVERTED INTO A CELL. LET'S CHECK THE VOLTAGE OUTPUT FROM IT NOW. SO WE'VE TAKEN A MULTIMETER.   WE'RE TAKING THE PROBES, JUST CHECK IT. PRAVEEN WILL READ OUT THE READING. WHAT'S THE VOLTAGE? 1.12 V. WE'RE GETTING MORE THAN 1V FROM THIS CELL. THIS IS COMPLETELY MADE OUT OF MUD. 1.12 V. NOW IT'S 1.11 V. THERE'LL BE VARIATIONS. WE'LL PLACE THE REMAINING CELLS AS A SERIES. OUR 4 BEAKERS ARE HERE. SO HERE WE'VE TAKEN A WIRE WHICH HAS CARBON ON ONE END AND ON THE OTHER END, WE'VE KEPT A ZINC PLATE. IN THIS WAY, WE'RE GONNA CONNECT A SERIES. WE'VE BENT IT AND WE'LL TAKE THIS WIRE. MOVE IT TO THE LAST BEAKER. CARBON IS HERE AND ZINC THERE.

 SEE HOW WE'RE CONNECTING. SINCE ZINC IS HERE, NEXT SHOULD BE CARBON. JUST INSERT AS YOU SEE HERE.   JUST LIKE THIS. HERE IT IS ZINC, SO THIS SHOULD BE CARBON.     MUD IS ALMOST DRY NOW. WE'VE TAKEN THE LAST PIECE. SINCE ZINC IS HERE, WE'LL PLACE CARBON. INSERTED IT     WE'VE CONNECTED THE CELL AS A SERIES. WE CAN CHECK THE VOLT. WE'VE TAKEN THE MULTIMETER. WE'LL CHECK IT. POSITIVE AND NEGATIVE PROBES ARE CONNECTED. PRAVEEN WILL READ OUT THE READING. 4.59 V. EARLIER WE KEPT ONE AND GOT 1V. NOW WE'VE GOT 4V FROM 4 ONES. WE'LL CHECK IF LED & MOTORS WILL WORK ON THIS.     WE'LL SEE HOW EFFICIENT IS THIS. SIMILARLY WE CAN CHECK THE LED AND MOTORS. WE'LL CONNECT THE BULB. WE GOT 4V FROM THIS WHEN WE CHECKED. SO LET'S TEST IF WE CAN MAKE A LED BULB TO WORK. 

WE'VE TAKEN A LED BULB. CONNECT THE LEADS TO THESE WIRES HERE. SEE THE LED BULB IS ILLUMINATED. SO THIS BULB IS ILLUMINATED FROM THIS MUD CELL. WE CAN CHECK IF A MINI MOTOR WILL WORK ON THIS. THIS REQUIRES MORE POWER. LET'S SEE. WHEN WE CONNECTED THE LEAD TO THE BATTERY... SEE! MOTOR IS WORKING IN GOOD POWER. EVEN THIS IS WORKING. SO WE'RE GETTING ENOUGH POWER FROM THIS. LET'S CHECK A MOBILE PHONE, IF WE CAN CHARGE IT.   FOR THAT WE'VE CUT OUT THE CHARGING CABLE AND CONNECTED WITH MUD CELL. WE'LL CONNECT IT TO PHONE AND CHECK IF IT IS WORKING. WE'VE CONNECTED THE CHARGING PIN. LET'S WAIT FOR SOMETIME. DID WE GET AN INDICATION? WHAT'S THE CHARGE IT IS SHOWING? 81%.   WE CAN SEE THAT OUR PHONE IS CHARGING. IF WE WAIT FOR 1 OR 2 HOURS,   IT MIGHT CHARGE FOR ANOTHER 3%. SINCE THE POWER OUTPUT IS  VERY LOW IN THIS. EVEN THOUGH WE GET MORE THAN 4V, THE POWER IS VERY LESS. SO CHARGING WILL BE SLOW. ALSO THIS IS NOT RECOMMENDABLE. 

WE'RE NOT SUPPOSED TO CHARGE WITH REGULATED POWER. WE JUST WANTED TO SHOW THE RESULT OF THIS EXPERIMENT.     WE CAN SAY THIS AS A DRAWBACK OF THIS EXPERIMENT. OUR EXPERIMENT WAS A SUCCESS. AFTER THE LOCKDOWN IS OVER, WHEN CLASSES START & IN SCHOOL EXHIBITIONS, WE CAN PRESENT THIS EXPERIMENT. IT'LL BE USEFUL FOR THEM. I THINK THERE WAS A MISTAKE IN WHAT WE SAID. WE TOOK ZINC AS ANODE AND CARBON AS CATHODE. I DOUBT THERE MIGHT BE A MISCOMMUCATION IN IT.   APOLOGIZE IF THERE'S A MISTAKE.
