Goals of this expedition

ENG: There are several objectives to this double world first expedition I want to reach:
Main goals:

1. Make the first unsupported crossing of Iceland from the extreme North to extreme South points (highest to lowest lattitude).
2. Do the journey twice: once during the summer (not too hard), once during the winter (very hard). IT will be a solo trek. No vehicle to help, no fooddrops or preplaced foodcaches. I will rely only on what I bring from the start.
3. Measure myself against the extreme elements/factors: wind, snow, cold, dehydration, exhaustion, loneliness, heat, rain, hail, whiteouts, "blackouts", ... and hopefully no waking up of volcanoes. This in order to learn how to survive into these elements.
4. Perform scientific research on how my body/mental will evolve during both solo trips: Stress and decision taking in extreme environments is a recent subject being studied to prepare future astronauts who will be exploring Mars and beyond. How will I be affected by walking during the summer in full daylight/twilight and during the winter in complete darkness/twilight.

Optional goals I hope to reach:

1. Take several photos from defined landscapes during both seasons at exactly the same place to have a wonderful idea of the contrast between winter and summer. A very interesting photo exhibition can then organized in several countries interested by the concept. Maybe a photo book related to the exhibition could be printed. Photos of wildlife is also interesting. Remark: the winter challenge will be very hard for photography as I won't have much light. A third supported trip in later winter (March) will probably be added with the only purpose of taking photos to complete the contrasted landscape photos.
2. Shoot HD to make a documentary.
3. Take notes for a future book and articles about the 2 trips.
4. Develop a new lightweight pulka that can be also a sleep device aka the "sleeppulka". With a fast set up, stronger than a tent and attached/part of the pulka, such a gear would help polar scientists or other explorers to be safer and survive storms. A glaciologist friend told me this would be a great tool for them. Remark: numerous expeditions fail because of tents destroyed by wind or fire, I expect the sleeppulka to resist this. And no I don't think it would be polar bear proof !
