  2. PROBLEM STATEMENT • The challenge is to design a portable system which produces 20 Wh energy for at least one hour by utilizing the energy wasted in household processes or the energy naturally available to us. • Changes shouldn’t interfere with the existing systems.

  3. PROPOSED IDEA We plan to use the excess heat dissipated through the sides of a stove to power up our system. It consists of these 3 principal parts:

  4. NOVELTY OF THE IDEA

  5. FEASIBILITY OF THE IDEA ( TECHNICAL) • The technology to produce such PVs already exists. • The system we have designed is simple and light, with minimal circuitry • Research into the components, be it emitter, photocell, etc has gained momentum and is likely to continue, yielding better results every year. Usage of cooking gas in average Indian home = 3 hours Energy generated in burning gas in 1 hour = 3-6 kWh We assume generated energy = 4.5 kWh Therefore, power generated = 4.5 kW & energy generated = (3*4.5) kWh = 13.5 kWh Energy available for conversion = ((27/100)*13.5) kWh = 3.645 kWh (Since 73% of the power is utilized in cooking and rest 23% is wasted as heat) Power available for conversion = 1.215kW 0.1m2 for a fuel input 12.3 kW causes 1.5 kW of electrical power output Thus for 0.0785 m2 for a fuel input 1.215 kW causes energy output = (1.5*0.0787*1.1215/12.3*0.1) = 116 W Thus, energy output = 348 Wh This amount is 17 times the target value of 20Wh $$$$$

  6. TECHNICAL CHALLENGES : (What could go wrong)

  7. FEASIBILITY : (COST PROFILE )

  8. COMMERCIALIZATION PLANS $

  9. CONCLUSIONS We can conclude from above points that cogenrative use of TPV is a very viable idea and it is no longer a question of if but rather a question of when……until then all we can do is put our efforts into it. Acknowledgements: Besides Tim Berners Lee(inventor of WWW), we’d like to thank our teachers and of course our parents for guiding and helping us. But perhaps most important are our friends who helped us out most when we were depressed or unwilling to go any further.
