Question:
Is algae ethanol an environmentally friendly alternative to food crop-based fuels and petroleum-based fuels?
Purpose:
To produce algae ethanol as an environmentally friendly alternative to food crop-based fuels and petroleum-based fuels.
Hypothesis:
Algae ethanol is an environmentally friendly alternative to food crop-based fuels and petroleum-based fuels.
Variables:
For purposes of this experiment following variables were identified and studied:
Independent Variables:
-
Different fuels (ethanol, food crop-based fuels and petroleum-based fuels) used to heat water.
- Ethanol produced from algae grown in different types of water - fresh water, river water and pond water.
Dependent Variable:
- Amount of fuel used - algae ethanol, food crop-based fuels and petroleum-based fuels to heat the same amount of water.
- Heat energy generated by algae ethanol, food crop-based fuels and petroleum-based fuels to heat the same amount of water.
Control Variables:
- Specific gravity of ethanol produced from algae grown in different types of water - fresh water, river water and pond water.
- Specific gravity of food crop-based fuels and petroleum-based fuels.
