Detailed within are some aspects of rural life, the terain, modes of transportation, people, and culture. This trip was related to field research into suitable areas for more portable and light weight solar cooker and heating system for the Himalayan region.

This takes approximately 15 minutes, creating a charge on the capacitor that could be lethal. The capacitor is then discharged through a 12" length of 30 gauge bare iron wire.</p><p>When the high voltage current flows though high resistance wire, the bonds between iron molecules are shattered, resulting in a loud bang, a shower of sparks, and a cascade of wispy filaments floating through the air.</p><p>Not all of the charge on the capacitor is disharged through the wire, so a shorting bar must be used to release the remaining charge. </p> 121 tag:techtv.mit.edu,:Array/219130260 2007-06-01 16:24:55 -0400 Doc Edgerton Films <p>Doc setting up fan, smoke, and strobe experiment, smoke curls around blades. </p><p>E255 </p> 25
