Too good to be true, oven makers were going to go out of business.
A Whirlpool electric single oven is on the surface-cooking-kindof oven; as for the Nesco Jet Stream oven it uses a a rack top. So for a more evenly cooking, I would go with the Whirlpool.
Yes, the Nesco JS4000TW will cook foods thoroughly without losing the vitamins and minerals that can occur with the runoff in a traditional oven.
How about direct from nesco, themselves? http://www.nesco.com/files/pdf/jetstream.pdf [try searching google, next time; it's the first unsponsored link.]
The jet stream
The polar jet stream is generally stronger and faster-moving than the subtropical jet stream. The polar jet stream forms at higher latitudes and is located closer to the poles, while the subtropical jet stream is located at lower latitudes. The polar jet stream is associated with larger temperature contrasts and stronger pressure gradients, resulting in stronger winds compared to the subtropical jet stream.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.

No. The jet stream is in the upper troposphere and lower stratosphere.

a jet stream is important because of climate control
