Around the World in a Solar Plane

    So, assuming he has clear skies for most of that trip, no problem. However, if he hits "inclement weather," how much energy does that plane store up before it runs out of juice? Or can it be assumed he will be above the cloud cover for the whole trip? And, is it assumed the trip is continuous or will he be able to stop at "jump points" (this makes more sense for obvious reasons). If he can stop even briefly, this idea becomes a lot more feasible.

    We need the wood.

    Spare me the "any mention of ecology gets a lukewarm response from the public because their comfortable existence is threatened".

    The problem with many so-called 'ecologists' is that they frame everything in terms of 'saving the Planet'. Here's a clue - the Planet will survive long after we're all dead. The Earth will be there when the sun becomes a red giant and eats it. We shouldn't save the Planet, we should save ourselves. Does the Earth 'care' if biodiversity diminishes due to pollution? Does the Earth 'care' if the light pollution causes algae disruptions in the Great Lakes? No. but we should.

    This project is great at raising visibility and research focus in the fields of energy capture, storage and motor design, but these folks aren't the Messaihs.

    So after a few years of r&D half a dozen custom built protoypes (to be discarded as non-biodegradable junk) and other discarded parts they can have something that probably took more energy to make than a small town uses in a year, but then fly it around the world using only energy from the sun...

    A Proof of Concept product is always more costly. You can think of R&D costs not concentrated in a single product, but amortized across the series of product lines inspired by the new engineering, whether those costs are money or calories or a balance of available resources. The long-term savings (in all economic senses) represented by efficient design suggests a real bargain for global society.

    The publicity stunt aspect of this is really a kind of marketing for sustainable tech in the long view.

    Perhaps we have a right to wipe humanity of the face of the planet, perhaps we don't. But I don't see how we have a right to wipe out all the countless other species and to poison the earth, sky and the seas.

    To use a famous quote, this is a beautiful planet, it's a miracle and we're destroying it.

    (Cue a dozen posts from people who think environmental awareness is for only for hippies high as a kite.)

      We aren't going to "wipe out all the countless other species" out there. I seriously doubt we could do it, even if we tried, at this point.

      We'll kill some, but we'll also create new environmental niches for other species to evolve to fill. The various rodents, and pets, and farm animals that have evolved and prospered in symbiosis with man may not be "exotic" enough to satisfy those high as a kite hippies you mentioned, but they are no less alive or a part of this world's environment.

      What one being sees as "poison(ing) the earth, sky and the seas" is just the opening of new ecological niches.
      The last time there was a truely large scale "poison(ing) (of) the earth, sky and the seas" was when plants first flooded the world with harsh burning oxygen, killing all sorts of anaerobic life, and giving birth to aerobic life and animals as we know them. I trust you don't see that as having been a bad thing?

      Whatever nasty reactive chemicals we spew into the environment are likely to become the food of tomorrow's most feccund life.
      Our nuclear waste and depleted ozone will generate mutations, and spur new evolution to fill those niches we're creating.

      We won't, we can't, destroy the planet; but we will change it.
      If you're so small minded that you have to classify everything that evolved before man as 'a good ecosystem' and everything that evolved after we became dominant as 'a bad ecosystem', then you're missing a whole lot of the beauty of this planet's life.

    Do you truly not see why developing solar energy technology to the level that makes this kind of plane possible is eco-friendly proejct, or are you just trying to troll?

    And it's not just developing better solar cells to enhance current applications of solar energy.

    Consider for example that if a lot of oribital satellites could be replaced with purely solar-powered autonomous planes that could stay up theoretically indefinitely. Just think how much "non-biodegradable junk" can this project produce to match the environmental impact of just a single space rocket launch...

    Or imagine a hydrogen fuel-cell car that could partly refuel itself in a sunny parking lot during the workday, and could keep moving (slowly) even if you run out of fuel. Not much use in higher latitudes maybe, but imagine southern China, India and entire SE Asia with 2 billion cars like this instead of 2 billion cars using fossil fuels.

    Just repeat after me:

    "It's all about money."

    "It's all about money."

    I have a 2kw solar system on my roof so I'm certainly not anti-renewable energy. I just think people should realize that the problem has nothing to do with technology or people's desire maintain their lifestyle because it's not even allowed to come down to that. It's about greed and established infrastructure. I don't think it's any coincidence that the major solar panel manufacturers are all owned by oil companies. I can't prove it but it doesn't seem unreasonable to assume that they are controlling the price of solar panels to keep the usage at a level that is comfortable to them.

    We have reached the level of corporate control in this world that is reminicent of the movie Rollerball (for those of you old enough to remember it). The U.S. courts and the EU and make a good show of protecting their citizens but corporations don't need to do anything illegal to get what they want. With enough money and lawyers you can blunt any reform that comes down the pike. Movies have to be more dramatic but the truth is much more banal.

    I'm glad Mr. Piccard has the ability to put together these inspiring projects. I wish he'd invite me to be on his team. I just don't think for a minute that it's going to address the real problem.
