One of the core concepts of PicoTurbine can be stated: Tell me, and I will forget. Show me, and I might remember some of it. Involve me, and I will master it. Based on this old tried and true adage, the kits that the company produces come with activity suggestions to get the young people into hands-on learning situations. One suggestion of the company is to demonstrate how heat can be produced by wind energy (the company's speciality) through using a “picture wire” for the heating element. PicoTurbine has found that people typically think of wind energy as being “cold” energy, and are pleasantly surprised to see how wind can be used for generating heat in the home. Another project suggests that the company offers is to have different groups split off in the classroom and then compare the respective wind turbines that they have built. They can see which ones produce the most or least electricity; which ones start up with the need of the least amount of wind power; and for very young children, which ones have the most aesthetic appeal.
There is a core curriculum that PicoTurbine has in mind for teachers to instil in their pupils. Renewable, alternative sources of energy include solar, hydroelectric, geothermal, and biomass in addition to wind-produced energy. When we use more alternative sources of energy, we decrease our nation's dependence on foreign oil supplies, which often come from nations who cannot really be called our “allies”. Alternative energy is already becoming cost effective when set against the fossil fuels that we are so reliant on currently.
PicoTurbine points out that wind farms and solar arrays are already letting their makers enjoy commercial success. In the last two decades, the cost of photovoltaic cells expressed in terms of per-watt has gone from nearly $1000 to just $4! It has been predicted by analysts that by the year 2015, the cost per watt should only be about $1 (in today's dollars). Students also need to be taught about the hidden cost of fossil fuels: pollution and environmental degradation. Air pollution from burning fossil fuels has been shown through studies to increase incidences of asthma attacks, heighten the effects of allergies, and even cause cancer. Switching over to clean, green energy found in the alternative forms would prevent air pollution and help bolster the environment.
