Where is it all

This one reminds me of those old “Tintin on the Moon” comics ?????? and how in the early fifties we were imagining the world and inventing crazy interesting concepts. Some of them could have benefitted us all, some others would clearly have no future ?? But I wonder; what happened to the Rolligon tire? ???? Rolligon tires are a unique type of low-pressure, high-surface-area tire invented by William Albee in 1951. Inspired by Inuit methods of moving heavy loads over soft terrain, Albee designed these tires in a way to distribute vehicle weight over a large area, allowing for travel across challenging surfaces like tundra, sand, and mud without causing damage. The tires can be inflated to pressures as low as 5 psi, enabling vehicles to traverse difficult terrain at speeds up to 16 km/h. Rolligon-equipped vehicles have found applications in the oil industry, particularly in Alaska’s North Slope, where they can efficiently transport supplies and personnel across the permafrost-covered landscape. I don’t know but this Rolligon tire technology seems like they could potentially be adapted for space exploration? It’d seem logical that the tires’ ability to operate in extreme conditions and distribute weight effectively could be valuable for rovers or other vehicles designed to traverse the challenging terrains of the Moon or even Mars, no? Their low-pressure design could be particularly useful in low-gravity environments, where maintaining traction and minimizing surface damage are pretty crucial. Anyway, I’m sure someone thought about it and there’s a reason why it was never used. If you know why, let me know in the comments below ?? ???

Nozzles: The New Technology New nozzle designs, such as the Rice Speed Nozzle, have been developed to improve propulsion efficiency. These nozzles feature a NASA-designed airfoil profile, which accelerates water flow and increases thrust. According to trials, the Rice Speed Nozzle achieved: 7% fuel savings 8-12% greater running speed 4-6% more bollard pull 8-10% more trawling thrust compared to traditional Kort 19a nozzle designs. Fuel Consumption Impact The use of nozzles can significantly impact fuel consumption in marine engines. By accelerating water flow and increasing thrust, nozzles can reduce fuel consumption by up to 22% or more on most trawlers, fishing, and tuna vessels up to 15 knots. Nozzles can significantly impact fuel consumption in marine engines, offering up to 22% fuel savings or more compared to traditional propeller designs. The Rice Speed Nozzle, in particular, has demonstrated superior performance in trials, making it a viable option for marine engine applications. https://lnkd.in/daMG7F24

This tessellation is based on the Gosper 13 space-filling curve, discovered by Fukuda et al., with deformed rhombus tiles filled with a bird. The generated segments of the curve indicate whether a rhombus must be rendered to its left or to its right (yellow). Each rhombus consists of two equilateral triangles. One triangle has its base on a curve segment, and one of its two remaining edges is the base for the other triangle. However, it is not obvious (for me) which of the two edges. I used some heuristical rules, as well as a search algorithm to determine the correct edges. After two iterations the tessellation has 13 * 13 = 169 tiles. The curve starts at the middle right, and ends at the bottom left. You can follow the curve on the dark edges of the birds. #mcescher #escherart #escher #mathart #digitalart #space #curve #path #bird #Tissellator

Dwarf planets are a fascinating category of celestial objects in our solar system. Unlike the eight classical planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), which have cleared their orbits of other debris, dwarf planets have not achieved this criterion. This means they share their orbital space with other objects, such as asteroids or other small bodies. The most well-known dwarf planet is Pluto, which was reclassified from a planet to a dwarf planet by the International Astronomical Union (IAU) in 2006. Other notable dwarf planets include Eris, Haumea, Makemake, and Ceres. Ceres, located in the asteroid belt between Mars and Jupiter, was the first dwarf planet to be discovered and is also the largest object in the asteroid belt. Dwarf planets come in various sizes and compositions. Some have moons (like Pluto and Eris), and they can have diverse surface features, including icy regions, craters, and even atmospheres in some cases.

Telescopic rods are not only good for measuring the height of a span ????

Space plane covers: These spatial structures are composed of planar substructures. Their behavior is similar to that of a plate in which the deflections in the plane are channeled through the horizontal bars and the shear forces are supported by the diagonals. #Spaceframe #Buildingmaterials #JointBall #Steelstructure #SteelTruss #SteelTrussStadiums #ACPpanelwall #Curtainwall #Membranestructure https://lnkd.in/gEDEN6J5
