Part of the latest design plan is to be able to raise the solar panels when my little boat is going on an epic adventure, rather than just a day trip.
During transit on the tralier, I want my solar panels as close to the deck of the boat as I can make them so they dont fly of in a direction of their choosing. I want them to be a little more under my control that the wind might, so keeping them low means I get a bit less wobble. If you don't know what I'm talking about, get a neighbour's kid (don't use one of your own) and see how much more they move about if you lift them up high on a post.
That's physics at work.
Or something.
But anyway, if you built a carport on 300ft long broomsticks, it would fall over in the first stiff breeze. But the same carport would hand it just fine if the broomsticks were only 4 foot tall. (I presume you drive a Ferrari)
So I want my solar panels to sit atop their low rise roof in 110 kph transit, but be extended to a more convenient height when I'm on an epic adventure. I don't mind stooping a bit to get under cover, but it will drive me nuts if I have to crawl under the panels if I ever need to sleep on board.
So..
The in the low rise version (road transit, and day trips) the solar panels will sit at around 400mm high.
In high rise mode, they will sit at more like 1200mm high.
In order to move from low to high mode, I figured I'd mount the entire frame on hinges so I could add the extension tubes first to one side, and then to the other by lifting the frame with one hand and adding the extension tubes with the other.
But I have a problem. I cant wrap my head around Newton and his pesky rules...
If I mount a 1.8m cube of grow house frame so that all four of it's legs are hinged to enable it to tilt around an axis running front to back of the boat, will it fall down, or will it's integrity be maintained by the structure of the top.
I realise the answer is going to start with "it depends", but arggggh!.
I want my old brain back.
120 Things in 20 years wants to start using the invention engine again. It's always worked much better than this brain thing.
