  how about the fantasy classic "time machine" ? if the time machine ever does become a reality, it will be done by engineers so lets get a start on it ; - )

  Well, we need something concrete to build upon. I doubt Time Machine will ever be created because if we'd ever create it; I'd definitely come back in time to visit myself. But I haven't met me yet, so ... 😒

  well, i don't know much about what is involved in inventing the time machine, but i know it is everyones dream invention. and of course, the first company to invent it will become instant trillionaires and be remembered for centuries. i can personally say that if i had 3 wishes, one of them will go to the invention of a time machine : - )

  Consider someone watching us right now from proxima Centauri. He will be seeing (right now) what happenned four and a quarter years back. However, he cannot act on it because any action initiated will reach the earth after another four and a quarter years. A net lag of about eight and a half years. This is because simultaneity is an anamoly in relativity because of the speed of light being fixed.

  thanks to the idea of this discussion.......but lets use it for the things that we can really do not jst talk.....
  i think that the invention of time mission is almost impossible for now..........of course i agree that every invention was thought to be impossible at first........
  so guys lets come up with all your crazy ideas which will definetly take a shape not just imaginations........👍
  and sorry if i hurt anyone...........😔

  i dont know about going back...bt it is possible to go to future if we invent a train that travels completly around the whole earth atleast 6 tymes per sec........that is to travel with more thanthe spee of light..............

  A study reported in the journal New Scientist taht the total sound energy out put of a full professor in engineering for a whole year when converted to electricity was worth about ten cents.
  
  Not worth the effort.

  if we come to the actual topic not only theoritical but also there are certain succesful experiments done which generated the electricity from sound......
  but unfortunately not all sounds are suitable for this.......and research is going on.....

  It is suitable only for very low power applications. It will not be suitable for any bulk use of power. Just think in reverse One can get an ear splitting noise from just a few watts output from an audio system. What I am getting at is that one needs a huge volume of sound to generate a modest power. If one can consider a laser like sound beam, then a suitable piezo electric device may be able to harvest it more effectively. Normal ambient sounds are not of much use.

  #-Link-Snipped-# yeah sound to electricity conversion is good idea to get electricity but it has some practical difficulties na by designing this kind of things with nano-technology it may be possible to get expected power from the sound👍

  Can you brief me about nano-solar technology

  yeah sure me too know few abt this oly upto that i'm telling k
  first of all solar technology is one to get electricity from sun's radiation of heat
  sun produces enormous amount of heat energy we utilize it by solar technology but by this technology we can get low power(in MW) oly inorder to get required GW from it we r moving to nano-solar technology
  In nano-solar technology, graphene is implemented to get required power
  A most disadvantage in this high cost effiecient one
  in future we can fully utilize the use of nano solar technology with reduceable cost researches r going on that to reduce the cost of it

  Why indeed? The amount of energy depends on the sound flux in watts/sq.cm. The larger the area of the interceptor greater the collected power. A moving coil loud speaker can do a better job than a microphone. Larger the dia of the speaker the better.

  then i think it is not beneficial for us to convert the sound(i.e,due to pollution) to power........

  Creating electricity from sound or noise is really good idea. Because if it become real then the street lights will work on that power and if noise is there then only they will glow and it is really useful for today's traffic and another application is in colleges and schools , in those areas the teachers will encourage students to do noise for power saving 😉 and many.... If we use powerful microphones to capture the small signals whose amplitude may be around 5 -10 mv then the signal may be amplified to 10 or 12 v using op-amp. Then we have to use regulators , amplifiers , power amplifiers to rise this voltage to 230 v 😔. I think it is some what difficult but surely becomes possible.

  Another crazy idea of me is to interface general book and social network like facebook. In detail a book will be there and in that book the first page is having email password and some identification like a finger print. Different types of books will be there based on the requirement of user. If user have 500 friends then 500 pages book will be there ... Then every individual page in that book is having information about friends i,e. profiles( one page for one friend). It becomes very easy to chat and the chat system will also be just like a mind reader( No need of typing or writing).

  If an order of magnitude calculation is done it will be known that this is a non starter.

  Why we wanna create electricity from sound/noise signals, when we are already using Natural resource "Sun" as for solar energy .... yeah the cells are bit costly .. but in recent years cost has dropped a lot.
  
  Plus, Production of electricity using noise/sound signals will increase noise pollution ....

  An object with mass can move with the speed of light or even more !
  Where ?? In Black hole !
  Black-hole has escape velocity (ve) greater than speed of light (theoretically)
  So if by some case we get trapped in black-hole we will be moving more than speed of light, so mass will be converted into energy ... In short, its possible.
  I am getting into quantum mechanics now , pardon me !😯

  Sir you are absolutely correct. Producing electricity from noise or sound is of not effective. The sun based electricity production is also there . But we are still strugggling with lack of electricity.On a cloudy day we may not have that much of effective solar energy but sound will be generated everywhere and on any day. Hence I think it is better to produce elctricity from the available sound. My idea is atleast to develope a circuit that can charge the laptop whle listening to songs , run the bulbs in railway stations and bus stops and highways which will definately crouded .
  
  Thanking you sir
• 

  Ramani Aswath

  It is important for an engineer to an order of magnitude calculation. We are always quantitative. The available sound has negligible realisable power. Unlike emf waves, sound waves are compression rarefaction waves. You need very large area collectors to get even tiny power out. If you are listening to songs from the lap top, how much of that speaker output do you think that you can recover? It just would not recharge the laptop. It will amount to a perpetual motion machine.
  I agree with you that sound is energy but very very low level energy. Not worth the cost of recovery.

  Thank you so much for your valuable response sir. I know that it is highly impossible. But it is one of my crazy idea sir.

  Nothing wrong with having crazy ideas. We should dream. With our heads in the clouds. At the same time we should have our feet firmly on the ground so that we try to actualize our dreams.
  I am sure that you know that a moving coil loud speaker can be used as a microphone. You can check it by connecting a sensitive meter to the terminals of the speaker and pointing the speaker at a source of sound. You will get an ac voltage at the terminals. You can see this much better with an oscilloscope.
  
  Alternatively you can connect the terminals to the input jack of any audiosystem. If you speak into the speaker (It is a listener now) you can hear your voice coming from the audiosystem. If you connect a large number of speakers in a suitable series parallel configuration you can harvest the sound energy. If one can collect discarded speakers, a low cost system may even be possible. It may noe be commercially viable.
  Who knows? If a thin film piezo electric heet can be produced with nano technology, it may even become commercial.

  Again, please do an order of magnitude calculation. An large adult human has a surface area of 2 sq.mtr. at 35 C skin temperature. Sometimes the ambient is higher than that in India. How do you propose to harvest that heat? You need a heat sink at a lower temperature than 35 C.
  Very difficult proposition.

  i dnt know if it is right or not.....but my idea is we know about spell checkers....
  and we also know about the pens that bears various softwares.......
  so if we dump the spell checking software into such a pen we can check the spelling.......
  if it goes wrong we set an arrangement so that beep sound occurs.....
  but it cannot be used anywhere...so i think its betr if its just a warning red light than a beep sound...
  its just my idea.....😉
  see if u can any leads by this.....👍

  The true time machine does not travel in space. It travels in time. Worm holes are for bypassing the speed of light in space travel.
