Hello i'm a fifth year electrical engineering student. i am planning to design and fabricate a low power alternator connected to a car exhaust. it's prime mover is a wind turbine run by the smoke emissions so that the smoke can still b useful. i just wanted to make something new because i think there are many projects made on piezoelectricity,TEGs and the like. is this a possible thing to make? and please can it make it to a power in Watts or just milliwatts? i'm also thinking for what i can use this power? thanks!
