Solar Impuls 2

homanmihhomanmih Posts: 716 ✭✭✭✭
Solar Impulse 2 (Si2) the zero-fuel airplane is currently circling the world. It is an experimental solar-powered aircraft.
Si2 will take off for its sixth flight from Chongqing to Nanjing China in day or two.
It might be the first expedition flying around the world by using only solar power without the need for fossil fuel.
Solar Impuls took off from Abu Dhabi on March 9. It is scheduled to return to the same location in August 2015.
This unique adventure is showing that with a clear vision we can go beyond what is currently possible, and to use Earth's resources more clever.
What do you think about the meaning of events like this in changing our life?
Let's fly with this amazing airplane, let's talk about exiting future fluently in the air.

    This mobile wouldn’t discharge anywhere. It can fly even day and night!
    It may surprise you yet.
    Let's imagine Solar Airways!
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    Solar Impulse stuck in China. The delay is due to bad weather, as the plane - wide as a Boeing 747 but as light as a car - requires almost perfect conditions in order to fly.
    The plane needs optimal conditions and cannot fly if wind speeds are above four knots (4.4mph or 7km/h)

    Thank you @homanmih for this interesting information.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    @ ManLearner The solar plane, that uses only solar energy, wihtout any drop of fuel will take off for its next flight in around the world trip in about 3h.
    Bertrand Piccard will fly the zero-fuel airplane on about 1190km for an estimated time of 20 hours.
    Solar Impuls 2 is presenting the latest clean greener technology. Future is clean.
  • ManLearnerManLearner Posts: 1,116 ✭✭✭✭
    @homanmih yes it is good for environment. But it will be challenging to use this technology for passenger aircrafts. However solar drones can be useful for courier or other purposes.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    @ManLearner Major companies are approaching this challenge in different ways.The NASA has Helios Prototype as unmanned aerial vehicles. Airbus is drawing up own project. But I have a real vibe with Si2. It'll take off in almost one hour.

    @homanmih I am a bit scared of these experiments. Hopefully, it will go well and we will get environment friendly projects.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    I have a real vibe. Right now Si2 are above the Yangtze River! It's flying above cumulus clouds in the Chinese airspace. I think it's a hystoric moment of the meeting ancient civilisation with future.

    Don't fear @ bubbli. The solar plane, that uses only solar energy, without any drop of fuel is attempting to fly around the world on nothing but solar power.
    There are nothing dangerous but only example of human intellegent behavior and using Earth's resources more clever.
  • BubblyBubbly Nightingale Posts: 30,268 ✭✭✭✭✭✭
    @homanmih On lighter side, What if their power ends while air craft is in air?:)

    Si2 wouldn’t discharge anywhere. It can fly even day and night!
    Solar Impulse will take off for its seventh flight from Nanjing in the People's Republic of China, to Hawaii in the United States of America. The pilot will fly the zero-fuel airplane on about 8,500km for an estimated time of 120 hours. This flight across the Pacific is a feat of endurance for the pilot, and for the support teams that constantly monitor and plan for Si2's route. Over 5 days, the pilot will head for the small target of the Hawaiian islands.
    The legs of the flight crossing the Pacific and Atlantic oceans are the longest stages of the circumnavigation.
  • BubblyBubbly Nightingale Posts: 30,268 ✭✭✭✭✭✭
    @homanmih So it is a testing flight or they have already tested it?
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    In 2014 they crossed over USA. Solar Impulse is the only airplane of perpetual endurance, able to fly day and night on solar power, without a drop of fuel.
    Solar Impulse challenge is to attempt the First Round-The-World Solar Flight in 2015. A way for they to demonstrate how pioneering spirit, innovation and clean technologies can change the world.
  • BubblyBubbly Nightingale Posts: 30,268 ✭✭✭✭✭✭
    Thats Interesting! But I never head about it before. It's really an interesting development so far.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    @bubbli That's very interesting for people but aren't pleasure for big oil companies. Becouse main media don't notice this bright event.
  • BubblyBubbly Nightingale Posts: 30,268 ✭✭✭✭✭✭
    @homanmih right!
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    Solar Impuls right now can be seen above Nanjing airport! Almost time to descent.
    Landing an aircraft with a 72m wingspan, weigthing only 2,300Kg, is a challenge for any pilot! Winds and gusts make landing Si2 extremely challenging due to its light weight and broad wingspan.
    The pilot must keep a slow rate of descent. Si2 lands at a speed of 30-33knots, with no tail wind and a maximum headwind of 4knots.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    You can be proud. Si2 has successfully landed in Nanjing!
    It's strategic location, close to the Pacific ocean, will allow the most thorough preparation before taking off for Hawaii, the most challenging flight since the beginning of the adventure.
    NEXT Flight7 will be Pacific crossing, the moment of truth!
    The pilot will fly the zero-fuel airplane on about 8172km for an estimated time of 120 hours, over 5 days.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    The First Round-The-World Solar Flight started and will ending its historic adventure in Abu Dhabi. It isn't by chance.
    The Si2 team was hosted by Masdar and Abu Dhabi for testing and training.
    Masdar City is being constructed in 17 kilometres of Abu Dhabi, beside International Airport.
    Designed by the British famous architector Foster, the city relies on solar energy and other renewable energy sources.
    The Masdar City Solar Photovoltaic Plant is the largest of its kind in the Middle East. The facility produces about 17,500 megawatt-hours of clean electricity annually and offsets 15,000 tonnes of carbon emissions per year.
    Masdar City is the world’s most sustainable eco-city, fantastic smart city.
    This is the first real arcology project.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    It's realy exсiting for humen beeings, but is very unpleasant to major oil companies. I think becouse main media don't notice this unique adventure.
  • [Ex Member][Ex Member] Posts: 47 ✭✭
    I am very exciting to hear that ... thank you for this interesting information
  • BobmendezBobmendez Posts: 397 ✭✭✭✭
    I think this plane can fly without any power supply for a while because of its weight. Like a kite :)
  • BobmendezBobmendez Posts: 397 ✭✭✭✭
    Let's hope the discovery of the Higgs boson will help to invent a kind of antigravity engines or global transportation system will never become green.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    @Bobmendez This single-seater aircraft made of carbon fiber has a 72 meter wingspan (larger than that of the Boeing 747-8I) for a weight of just 2,300 Kg, equivalent to that of a car.
    The 17,000 solar cells built into the wing supply four electric motors (17.5 CV each) with renewable energy.
    During the day, the solar cells recharge lithium batteries weighing 633 Kg (2077 lbs.) which allow the aircraft to fly at night and therefore to have virtually unlimited autonomy.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    After 10th May Solar Impulse will take off for its seventh flight from Nanjing in China, to Hawaii. The pilot will fly the zero-fuel airplane on about 8172km (4412NM) for an estimated time of 120 hours, over 5 days. This flight across the Pacific will be the most importent event in real using of clean energy.
  • BobmendezBobmendez Posts: 397 ✭✭✭✭
    @homanmih The question is How big the aircraft should be when transporting at least 100 passengers. Can such a green machine be built?
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    It isn't the time for such a question yet. But electric car "Tesla" is the best example.
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    Kofi Annan message of support to Si2. We are proud to count him amongst the patrons of ‪#‎futureisclean‬!
  • homanmihhomanmih Posts: 716 ✭✭✭✭
    Si2 took off from Japan's Nagoya at 18:03 GMT on Sunday.
    The journey to Hawaii is expected to take approximately 120 hours: 5 days and 5 nights.
    It will be the longest-duration solo flight in aviation history, as well as the furthest distance flown by a craft that is powered only by the Sun.
    The Pacific crossing is the eighth leg of Solar Impulse's journey around the world.

    The Stanford Solar Car Project just unveiled its next generation sun-powered car: the Arctan. The solar array built on the Arctan’s upper surface is composed of SunPower Maxeon cells, one of the most advanced solar cells available. In order to increase the vehicle’s performance over the team’s previous model, the Arctan was manufactured using lighter materials and a more efficient method of solar cell encapsulation. This new system resulted in a 50 percent weight reduction over the previous model, the Luminos.

    'Arctan' will take part in The 2015 World Solar Challenge, that will start in Darwin on Sunday 18 October and finish on 25 October 2015 in Adelaide.
