Solar Impulse 2 Breaks Three Records En Route To Hawaii

Zothecula writes: Solar Impulse 2 has started smashing records even before the longest leg of its round-the-world flight is complete. At around three quarters of the way to its next touch down in Hawaii, the single-pilot aircraft has broken the world records for longest distance and duration for solar aviation, with the record for longest ever solo flight of any kind thrown in for good measure.

    It seems that in the modern era of flight, with high tech radio and navigation equipment, and modern weather forecasting, that solo flight isn't quite the feat it used to be. Not to say that this is easy, but it doesn't seem like it is the risky endeavour it used to be, either.

    Records are almost always broken due to advances in technology, or at least knowledge. Better equipment or better training are consequences of improved knowledge. But it still counts. Even track records are due to better shoes, and new knowledge of how to train the human machine. The four minute mile was once the holy grail of track, now it is routinely run under 4 minutes. Technology plus knowledge.

    Since you can't be bothered to actually read the article (yes, I know, who does that?), here is a quote:

    "Solar Impulse 2 took off from Nagoya, Japan on Sunday for its audacious five-day flight across the Pacific Ocean to Hawaii with Swiss pilot and Solar Impulse co-founder André Borschberg at the helm. It has since stayed in the air for three days and nights without using a single drop of fuel, grabbing the distance and duration records, 5,663 km (3,518 mi) and 80 hours respectively, in the process."

    Hoping it's not too much for you to read, you should be able to see that the plane does not fly only during the day.

    This isn't some jet engine which does this in a few hours.

    Really? New shoes make you run faster? Physical speed & endurance records are usually broken because of psychology. When the Kenyans started competing in marathons, they weren't winning because of their shoes or because of the teams of scientists training them back home. Often they literally had neither shoes nor coaches.

    For any particular record it's easy to point to the shoes or some special training technique to explain what put them over the top. But if you look at the evolution of how any particular record is repeatedly moved over time, it quickly becomes apparent that technology isn't worth nearly as much as we thought it did. And psychology becomes one of the most important critical factors, if not _the_ most important. People train and gauge their progress by what they believe is possible and achievable.

    Where technology (i.e. shoes, training, etc) really shines is in preventing injuries. But the time, place, and participants of record-breaking events are mostly anomalous. I doubt the pace of record breaks would slow much if we went back to the prevalence of injuries of 50 years ago, _presuming_ there wasn't a concomitant _psychological_ impact which dissuaded athletes from trying so hard. There are over 7 billion people on this planet, more than enough fodder to throw at breaking records.

      For sure birds *are* solar powered, where do you think the energy for making plants, other animals, and for moving air is coming from?

      The point with clean energy is that the time interval between the arrival of solar energy on earth and the moment we use it, it transforms into heat and is finally released into space as infrared radiation should be short with respect to the longest time-scale of our ecosystem, so as to not disturb it too much. In this way the carbon released into the atmosphere remains bounded.

      Jet planes use oil which normally does not participate to the ecosystem. Oil needed 100's of millions years to accumulate, if not more, and releasing this carbon in a couple of centuries is not the smartest idea. The solar or not origin of oil is irrelevant.

    Its one of very few solar powered manned aircraft to have ever flown, of course its going to be breaking records. That "longest ever solo flight" is less impressive when you consider that it HAS to be flown by a single person because built as flimsily as it is it can't handle the weight of a second person. And I am wondering if it is pushing for another record, longest time ever transit time for an aircraft. It left the start on March 9th 2015 and won't get back there until sometime in August. That's almost 5 months, your average commercial jet could make that trip in a couple days. Heck an unpowered balloon circumnavigated the planet in about 20 days and it didn't need to stop a dozen times. Its an achievement to be sure, but not the most practical that I've ever seen.
