Idea #2- To make lemon, coin and vinegar cell/battery commercially available
THE LEMON CELL IS A GOOD CONCEPT BUT IT IS STILL NOT COMMERCIALLY AVAILABLE.THE FOLLOWING PICTURES WILL GIVE YOU AN IDEA OF THEIR WORKING

A lemon battery produces 0.906V and that is not capable to replace the 1.5 V battery but the addition of more lemon juice and vinegar combination can resolve our problem. I want you people to think of some new ideas to increase the voltage. Also find if the carbon rod from old batteries could be useful in some way to our lemon cell. Lemon cells will promote agriculture rather than mining activities done to extract the raw materials for normal cells of 1.5V.

The future is lemon cells , just we need to expand our area of knowledge and find new possibilities like the use of foil paper in the lemon cell.

All the best guys, keeping thinking and exploring!

Check this out and give suggestions . Hope you like it 👍.

The jaali ( cross-sectioned wire system) in front of the cooler's fan is on the same principle (Bernoulli's theorem) that was used in the ancient monuments .👍
Propose more applications using this jaali .
Best of luck innovators 👍.

Geo magnetic levitation shoes

               - Tanuj Handa(BCE,USCT,GGSIPU)

The ideology based behind this idea is that , since the earth can be considered as a magnet with magnetic field moving out, a device can be made which can generate a magnetic pole opposite to that of the earth.

This can result in levitation on earth, and based on intensity of field from shoes, the height of levitation can be controlled.

You can also suggest various extensions of this idea and how to make it more efficient and more practical.

Till then , stay tuned 👍

Q- Can you tell me a trigonal bipyramidal coordination compound which is not a metal carbonyl and also does not follow E.A.N rule(effective atomic rule) ?

All the best guys 👍

THESE NEW TECHNOLOGIES CAN REALLY MAKE OUR ENVIRONMENT MORE ECO-FRIENDLY. PLEASE SUGGEST SOME EXTENSION OR FLAWS IN THESE IDEAS.

Q- Can anyone tell me the most important reason for these kinds of windows in ancient monuments?(let's see who answers first)🤓

Idea#1-Generating electricity from body temperature

The two main methods-

1.TEG(thermo electric generators)https://www.google.co.in/amp/s/phys.org/news/2007-08-electricity-body.amp

Although they are semiconductor devices and even difficult to manufacture,as a result they are expensive.

2.Why not use a thermocouple ?

Use of thermocouple is still not a fast growing idea because many feel that it cannot generate much electricity but one must know that in India ,a person's body temperature changes at a high rate than in the US .So, I suggest people to use this idea and innovate.

3.People do suggest more ideas as we need ideas to grow and develop our world and help mankind to evolve.
