At least Lincoln and Jefferson designed some practical devices. Name a 20-21st century President who has.

Some people like Bessemer with a 100+ patents are bound to have a few that don't cut the mustard, but his steel processing changed the world in profound ways.

"In 1898, Scientific American published an article called Bessemer Steel and its Effect on the World explaining the significant economic effects of the increased supply in cheap steel. They noted that the expansion of railroads into previously sparsely inhabited regions of the country had led to settlement in those regions, and had made the trade of certain goods profitable, which had previously been too costly to transport."

Man that is freaky to watch . but these huge ships have to have flex or they would break apart

[Radioman]

When it stops flexing like that is when you have to worry!

Like P.M's they are all too busy blowing off hot air & saying they understand folk & economics. Trade & Jobs? I see where RECORD (UK) are starting to rebuild their home industry. Sorry , I'm on a side-track again.

I am beginning to think we can explore this nautical motion compensating theme forever. Here we have a rotating interior in a racing sailboat.

[Frank S]

Not sure I understand the reasoning for having a rotating computer console and coffee pot in the lower cabin of said boat, it doesn't appear to be compensating for anything other than access to other areas in the cabin. Maybe seeing the concept from a different vantage point or seeing it in use while the vessel is underway might help.

Per my recently-acquired expertise (5 minutes ago), I can tell you that what's not visible here is that batteries and hydraulics are concealed under that console, so that these heavy items can be moved to windward as desired. Interesting, but probably largely gimmicky; this is for the cruiser who wants to go fast.

A friend of mine up in Minnesota bought a 63 ft sailing yacht a few years back I don't know how much it set him back but I do know he said it cost more than 3 of his soybean combines. I don't think it was new but the way he described it, it was posh to the max. One of those things like some top end sport cars you have to be invited to purchase one. He said he and his wife had to spend months in Sweden attending a factory sponsored training course then make 3 5000 mile yachting ventures before they would even sell it to him. I've crewed on a few small regattas and I know he had years of sailing experience prior to wanting the thing so I can't imagine what all was in his yacht.
Gimmicky? Probably but who's to say
