-feels power-loner-difficult time with relationships and jobs-Physical disorders

What is an accelerant?

Example…

-A petroleum product used to start or

enhance a fire -gasoline, kerosene, paint thinner

List some observations from the NOVA video.

-No common accelerant used-business types burned are the same (craft, furniture and fabric stores)-took place near a highway-point of origin was stuffing and

pillows-occurred near times of firefighter conferences-time delay device was a used (match, cigarette, rubber band with paper,)

What are the disadvantages to alternative fueled vehicles?

-CNG compressor in fueling system is expensive.-Electric- initially more money, batteries are expensive, heavy and don’t last, recharging situations not in place yet.-H2/ Fuel Cell- manufacturing and operating costs are high, and high quality H2 is expensive.-Hybrid Gas/ Electric – Still produce some polluting emissions.
