Biographies
Ray - Ever since I was 6, I've always wanted to work in the science field. I started off with taking apart different electronics such as cameras and radio controlled cars. As I got older, I began to disassemble more significant electronics. At the age of 8, I took apart a computer and a tube monitor. Inside the tube monitor, there was a high voltage transformer which I enjoyed playing for quite a while. At the age of 9, my parents got me my first soldering iron. It was a 100 watt soldering iron and that was what started me off in my journey in the electronic world, building different circuits, lasers, and coilguns. When I was nearly 10, I decided I needed a computer, so I built my own computer from two junked computers, swapping the motherboard and the PSU. Now, at the age of 15, I take on much more advanced projects, such as a 2500 watt electric bike, a fully water cooled computer, my 1500 watt home theater sound system, and a solid state musical Tesla Coil. I get my inspiration from everyday daydreaming and I believe the rest of my life will include my passions in engineering science.
Pearl - Bookworm, techie, a to be engineer, passionate awarded speaker and an international science award winner- I am Pearl and I’m a dreamer. What’s my story? At seven, I made a toy car that worked on water. Ever since, my dream was to design an actual car like that. I researched and thought of designs for days, only to one day read in a magazine of car that worked on water. Being extremely put down and frustrated about not being the first mind to this idea, I learnt, that growing up in a highly competitive metropolis needed me to be unique- to set goals and strive for them. Coming from a past city where pollution is a major concern, doing something for the environment has always been on my list. That’s when working with solar cells and thermoelectric generators made complete sense! Developing and working on something that would be a potential solution to environmental concerns, is what drove me into this project. If given the opportunity, I would love this design to be mass-produced and made widely available. I now believe, if anyone has a goal- even if it’s not the first- they should never give up!

Concentrated Photovoltaic Thermoelectric Hybrid Systems (C.P.T.H.)
Challenge:Innovation
Category:Intermediate
Region:Greater Vancouver
City:Richmond, BC
School:R C Palmer Secondary
Abstract:In this project, a photovoltaic and thermoelectric hybrid module is developed, which produces electricity and delivers a higher efficiency than conventional solar cells by using thermoelectric generators to capture the waste heat. A parabolic dish is used to concentrate sunlight onto a PV cell and a passive thermo siphon cooling system is used to cool down thermoelectric generators.
