When the grade 12 physics class started building a go cart in February 2006 together with WESC, the idea was to build a go kart that basically had the layout of a normal go kart, except for the fact that it was not supposed to produce any type of emission. In other words we had to resort to an alternative source of energy. At first we thought about building a solar powered go kart, and the idea seemed quite good at first, especially since the sun is always shining in Egypt, but as we thought about the design and cost of building a solar powered go kart we ran into some problems. First of all solar panels are quite expensive, we looked at prices for rather small solar panels and saw that these were already over 100$US a piece, plus they would add a considerable amount of weight to an already quite heavy chassis. Second they would have to be mounted all around the go-kart in order to achieve a good amount of energy being produced from the panels.

With this in mind we started looking at some alternatives: we thought about building a fuel cell and using it as our main source of propulsion, but again the cost was simply too much for us. So we came to the conclusion that we would build an electric go kart powered by car batteries (but rechargeable by solar energy). We went out and bought 2 car batteries, each putting out around 70 Amps. With the batteries purchased, we also bought a used Hyundai steering column (including the steering wheel and the steering shaft) suspended by ball bearings. This was quite useful, as the cover offered a few mounting points, so we could use it to solidly attach the shaft to our chassis.

We were ready for a visit to WESC, to prepare the barebones chassis with proper dimensions we had calculated from a 1/20 scale model. We spent the next few weeks building the go-kart piece by piece. After the chassis was built, we mounted the rear axle, welded the front wheel attachments, configured a break, engine, and battery mount, as well as placing the seat on the cart. The last steps were to properly mount the engine and connect it to the axle with a motorbike chain, and with a gear ratio around
3:1. This gear ratio is laid out for a high top speed, but provides rather poor acceleration.

The kart was presented at the CISE Science fair after some last preparations, which included giving the kart a black paint job and doing some last minute reparations to the steering and rear axle, caused by the transport to and from our school.

I think Mr. Ian, our physics teacher, as well as WESC and of course us: Hadir, Shamarke, Kary, Waleed and Felix can be proud of the overall result. Below we have some pictures of the building and finalizing processes of the go kart.

Our first day at WESC, Felix is designing the 1/20 scale model of the go kart


The basic scetch of what it is all supposed to look like


Kary and Shmark checking whether to wire the batteries in a Series of Parallel circuit

The first metal work for the chassis being done, Kary paying close attention...


The first look at the complete barebone chassis


Calculations being done on certain dimension values for the chassis

February 27.2006


Felix and Waleed Examining the front skid plate that was installed while we were gone


Hadir attaching the mounts for the seat


Installing the Brake mount with the worker in charge of the welding


Waleed attempting to weld a part of the brake mount

The go kart is coming together nicely, batteries mounted, chair fixed, and steering being prepared


Everyone looking focused as we try to tune the brake


Sometimes things got a bit boring, but that is part of the process


After the Science fair, our go kart was complete and the end result impressed us all

In Conclusion it seems we can all be satisfied with the results, even though we were uncertain how everything was going to work out at times, we managed to put it all together into quite a respectable package. All of us gained practical experiance, as well as team coordination skills, as all of us had parts to focus on and people to work with. It was a great experiance for all of us and we are all glad it worked out the way it did. A big thank you to WESC for supplying us with a workshop, a team of mechanics and various materials we needed to complete the project.

 


Environmentally Friendly Go-Karts
Take CISE By Storm!
By Kirolos Iskander

In today's day and age there is a definite energy crisis plaguing the world, there is simply to petroleum based fuels to accommodate the every growing demand of gas guzzling internal combustion engines. This is not the only problem, inefficient engines and accumulations of greenhouse gases are exacerbating and accelerating the ever present threat of global warming and on the same wave length the emission of these gases are degrading fragile ecosystems and the natural environment as a whole. This is especially true when one looks at the gaseous cloud looming over Cairo's inner city. In a recent assessment done by the WHO Cairo ranks along side the likes of Mexico City in terms of the world's worst cities in terms of air pollution. Cairo streets are a medley of old cars and inefficient engines which release copious amounts of carbon dioxide into the air. A recent project initiated by a local non-profit organization referred to as the Wadi Environmental Science Center has put forth an idea that is attempting to curb these troubling trends.

Incorporating several schools and universities the Wadi has set up an interactive program which allows physics students and future engineers to build their own go-kart. There is of course a twist, the cars must be environmentally friendly and must be devoid of any greenhouse gas as a by product of propulsion. Universities and schools were given several ideas as too what form of propulsion could be used, these ranged from hydrogen powered cars to solar powered cars. Students were too choose how and where the go-karts were too be built and were even assigned the trying task of finding materials including the motor. I had the opportunity to take part in this process along with a team of my colleagues at the Canadian International School of Egypt as a final project for all grade twelve physics students. My colleagues and I spent countless hours searching for spare parts in the shadiest of Cairo's streets. Day after day we searched for spare parts including batteries and a working motor, often times bargaining with stubborn sales personnel to no avail. After shopping my colleagues and I travelled back and forth to the Wadi often twice a week over a period of one month to aid the in the manufacturing of the chassis and the assembly of parts. This was no easy task, problems ranged from a lack of parts, absenteeism and lack of proper planning often times resulting in both internal conflict and conflict with the on-site technicians. After a month of fine tuning and hard work, we managed to build a battery-powered car, rusty and slow but none the less functional and ultimately the fruit of our labour.

It is safe to say that the world's energy problems are the responsibility of those who inhabit the world, but often times we are careless and apathetic when we address this issue. Projects such as this give the youth a chance to consider this responsibility and give them the opportunity to attempt to address this on going problem not only by word of mouth but by action as well. I found that this experience helped open my eyes to the reality and prevalence of this problem in today's modern world, it also gave me hope that perhaps there is still time for us a people to change and focus on reversing come of the damage we've done to our earth. Ultimately our predecessors have placed the burden on us to assume a constructive and improve the global condition not only for ourselves but for those to come.
