I know the purpose of Planet Solar was a one-time mission only, but there was not much redundancy built into it, like spare motors, easy access to the internals components or even a drilling/welding station. Apparently there wasn't even a water maker on board and they had to buy bottled water, kinda of a bummer when you think of all the electricity and time they had at hand. Yes, they were energy independent but they were very dependent on everything else.

As a demonstration of what is possible with solar, I think it's up there with the solar powered plane. I was cruising round the UK canals in a solar powered narrowboat in 2013, a very practical application of solar for a live-aboard boat, given the low cruising speeds on the canals. On cloudy days, there's still ample power for onboard appliances and trickle charging the battery ready for the next good weather cruise.

There is an arrogance here in saying that solar is everything and the only way to save the planet. This is simply not true and surely a way to fail the planet. Solar is important and will be more important, but it cannot do everything or even most things that will be needed as populations continue to grow. Nuclear is necessary to fill the gaps and provide baseload power as well as process heat for heavy industry, all without putting a single molecule of CO2 into the atmosphere after construction is complete. Nuclear can be used to pull CO2 out of the atmosphere and turn it into fuel for the things that still need carbon-based fuels. That will make a closed loop out of that issue while the electricity generated with nuclear will power almost all vehicles and even some airplanes as batteries get better. Nuclear will power desalination plants to provide fresh water to coastal areas and possibly beyond so that we can quit draining our natural aquifers and drying up our rivers. Nuclear can make heating greenhouses for year round production economically possible. Greenland and Iceland already use geothermal heat for that purpose and other places can also do that where feasible. Modern reactors cooled with molten salts can run at more efficient higher temperatures without using high pressure steam which is the source of so many problems. Those reactors can then be sited away from our precious water resources, getting rid of the threat of contamination. These are the things which will be needed to close the loop where solar can't and avoid the heavy mining necessary to build enough batteries to close that loop. We have enough fuel to run molten salt reactors for centuries already in the pools around present reactors and when they are done using it, the remainder will be much lower in volume and much shorter lifetime. What's not to like? I know that you couldn't get me on a boat that couldn't make enough speed to avoid a reef in a storm. Your boat is beautiful but woefully inadequate and there doesn't seem to be much room to make it less so.

Surface piercing props, The center of the prop sits just above the waterline and the blades slice into the surface at an angle... Seems like a Strange choice as usually surface Piercers are used for VERY high speed applications where fully submerged props would cavitate from the extremely high RPM needed for those speeds, And are only normally used on high speed "planing Hull" types where the boat uses it's speed and shape to generate lift and Skims along the surface of the water like a water skier... However surface propellers enjoy a very significant efficiency advantage. This advantage is most dramatic for low-speed applications, but is still present throughout the performance spectrum. for getting more distance traveled for any given amount of energy, the best way is to go slow and stay fully immersed in the water with what's known as a "full displacement" Hull type, essentially those beautiful streamlined hull shapes on pretty much any sailboat. And you travel at or under "hull speed" which is usually pretty slow, though is higher the larger and longer you boat is, Which means large ships can travel at a higher speed efficiently than small boats... A 300ft long ship may easily slip through the water at around 20 Knots using comparatively little power considering it's size, Where a 46 Ft trawler type hull may be limited to around 7 or 8 knots, if it tries to go any faster then all it really does is pull half the ocean behind it generating huge drag For example the 46 foot boat At 7 Knots is only using around 20 Horsepower and can cross oceans on a single 1000 Gallon tank of diesel, where's if it opens up with the full 300HP it may only reach around 12 Knots and burn through all its fuel before getting anywhere far, massively inefficient

The story starts out, that one noticed a glacier had disappeared and we must do something about what we are doing to this planet. Well, I stood on a mountain top, with massive round boulders that clearly did not fall to that spot but was carried there, by glaciers. Looking down from the mountain, I could picture how massive the glacier must of been and wondered how many more feet over my head it would of been. But it was gone, before the invention of the first combustible engine. Climate change without mans interference had removed thousands of feet of ice cover. Another cold period arrived hundreds of years ago, called the "little Ice Age" and ended pretty much when the thermometer was invented. That's why when you hear of "record heat" it really is not a record at all, it is just recent recorded history. The Earth has been around for more than 150 years and has been warmer, I promise you. Off the coast of Florida, a few hundred yards and more than 30 feet down are a series of Native American burial mounds. The fact they were built on land, to bury the dead and are more than 30 feet under the ocean should give you an idea of how much the oceans have risen without the help of man destroying the earth. As for the boat, it is nifty, but 15,000 pounds of lithium batteries needed to promote "clean energy" did not fall from the sky. Massive mining trucks with huge diesel engines were needed to mine the raw materials which were put on massive ships with even larger engines burning fossil fuels to bring them to factories running off of fossil fuels and shipped to locations for assembly with huge fossil fuel engine trucks and trains. A lot of fossil fuels were needed just to make your clean energy boat, NO?

You are absolutely right, climate change has been going on without us for a very long time, but I don't think climate change is the entire question. In any case the term been politicised and this is about reality, something politics is completely unfamiliar with. The real question is, are we humans living sustainably on this planet? If the answer is no then it follows that, unless we do something about it, the inescapable consequence is our extinction because unsustainable is, by definition, terminal. If the answer is no, and there's an abundance of evidence to support that, then our species continued existence is at risk and this is where climate change comes in. The climate may well change to a state outside of the relatively narrow parameters we require for life, something it's done many times, and that spells the end for us. Life would probably continue on this planet, just not ours.

Get up to speed on technology please

Aug 6, 2020 - Carbon fiber fueled from rayon or the petroleum pitch process. But now dumped and ageing craft are breaking up, releasing toxins and microplastics across the world. The International Renewable Energy Agency (IRENA) estimated that at the end of 2016, there were around 250,000 metric tons of solar panel waste globally. The solar panels contain lead (Pb), cadmium (Cd) and many other harmful chemicals that could not be removed.

I have a feeling they plugged that boat into shore power to charge the batteries every time they got a chance.

Посмотрел с удовольствием!👍👍 Один вопрос - Гребные винты наполовину в воздухе висели и молотили над водой.... Это так задумано, или это экспериментальный прототип?

It needs about four vertical axis wind turbines, two of them could be attached to a gearboxs then a shafts & propellers. Wind & solar power is all you need & lithium-ion battery bank to store energy.

If they wanted to test wind turbines they would have done that. This is about solar

Ce documentaire fantastique est un coup de pied au front de tous les terraplanistes, qui doivent être des gens très désolés parce qu'ils sont piégés par les limites d'un militantisme idéologique inutile au lieu de profiter des merveilles de la planète. Mais je ne suis pas désolé pour eux, car l'ignorance n'est pas une option, c'est une maladie. Du Brésil ... Des câlins .

Super! Ako sa môžem zúčastniť takejto plavby? Aj ja!

The people on the bow told me this is not a "giant" boat. And it better have a sail.
