ISTF Project #

ISTf Project # 11-2528 was developed in response to the 2011-2012 Internet Science and Technology Fair."

Our National Critical Technology category is Energy and our sub- area is Renewable energy- Biomass Fuels. Our main objective is to extract bio- ethanol, which is a bio mass fuel, from algae, specifically blue- green algae, without actually killing it.

When you go out onto the street, you notice a lot of cars and other vehicles on the road which emit a lot of smoke to communte from one place to another. This smoke contains a lot of carbon which help in depleting the ozone layer. Every year, the breach in the Ozone layer is growing bigger and bigger which is leading to many environmental changes and health problems.

Also, the gas used to power these vehicles comes from none other than the burning of fossil fuels, for example coal, bauxite, which is other big contributor to global warming. Adding to this, fossil fuels are non- renewable resources, in other words meaning that once they are used up, you can no longer get them back. This means that the world will eventually run out of these resources and won't have an efficient source to obtain energy from.

Scientists have introduced biomass fuels into market as an alternate fuel because they emit 70% less carbon than actually petrol. Since then bio- mass fuels have become very popular in countries like Brazil and Mexico where are recent survey shows that more than 30% of cars on road in Brazil are bio- mass fuel operated.

This Bio- mass fuel (bio- diesel, bio- ethanol) is obtained by fermenting animal feed stock (corn, potato, sugarcane, algae, anything with cellulosic biomass in it).

This still doesn't help stop the growth of the breach in the Ozone as we obtain this fuel that releases less carbon into the air by killing and fermenting those plants that breath in carbon dioxide and release oxygen. This process is still harmful for the environment and as our point is to be eco- friendly, we want a way to extract this fuel for cars in a more eco- friendly way i.e. without killing these plants.

The picture above depicts how the breach in the ozone has been growing year to year and shows us that we need to take immediate action in regulating the amount of carbon emitted into the atmosphere

Our process not only helps with the problem of global warming by emitting less carbon into the air, but it also helps save non- renewable resources for generations to come.
