Undergrad Can a Wind Turbine Powered Boat Travel Directly Upwind Without Storing Energy?
It gets a bit complicated. For one thing due to real world situations due to wind shear as you go from (near) stationary sea surface where wind velocity is near zero, to full wind velocity at altitude you can make it work without any pitch adjustment. The energy harvested by the turbine 10m...- silverslith

Undergrad Can a Wind Turbine Powered Boat Travel Directly Upwind Without Storing Energy?
Been done by a few people. Seen a 30ft boat with a windmill -water screw setup firsthand. With a vertical axis , vane setup with cyclic pitch control you don't even need a drivetrain and waterscrew. electric Motor/generator on it and you can motorsail or generate and/or sail. Losses are less...- silverslith

Graduate Is there a func' for ideal x-section area in a resonant beam?
Obviously it has to taper from the fixed end to the most mobile one. Or from the centre (node) of a symmetrical one to the ends (antinodes). Talking about longatudinal harmonic resonance only here. Ideally the static instants at full compression or tension would give a constant...- silverslith

Tectonics driven by ice mass changes?
It may be that the long term carbon cycle is not a steady conveyorbelt but a periodic system. The usual exit from glacial periods might be from CO2 expelled through volcanism from recycled crust by the pressures exerted by ice masses on antarctica, sth america, greenland, nth america and nth...- silverslith

Tectonics driven by ice mass changes?
I'm not saying that mantle convection cannot move plates. I'm sure it can. And that might cause a stable smooth and gradual movement, that is predictable over MA+ timescales. I'm concerned that magma containing high percentages of water is far more fluid than the deep mantle, fairly standard in...- silverslith

Tectonics driven by ice mass changes?
I've read that there's no more heat flux in the mid ocean trenches as in "subduction" trench areas and other faultlines at present. That midocean ridges are compression features from isostatically driven volume adjustments buckling them recently, not spreading forces from vulcanism in the...- silverslith

Tectonics driven by ice mass changes?
Increasing glacification creates crustal tension pulling apart the mid ocean trench zones? Decreasing glaciation sucks out the stuffing and wreaks havok with compressive stresses, violent crustal crumpling and dropping of vunerable thin seafloor and mobile landmass plates? Seems a plausible...- silverslith

Graduate Production of C14 in the upper atmosphere
Not at all Vanadium. Thank you for the attention, but the energy density of the particle fluxes in the belts is not comparible to what is able to flow in in less temporally constricted processess. How do we define "correct" whether observational or belief based here anyway? I'm just at this...- silverslith

Graduate Production of C14 in the upper atmosphere
I'm getting over 3 kilowatts per sqcm as an energy flux from those electrons. At typical nuclear reaction level quanta for the electron energies that make up that total. Is there some kind of political problem that is preventing peoples engagement with this subject matter?- silverslith

Graduate Production of C14 in the upper atmosphere
perhaps the intricacies of nuclear shake and bake in the atmospheric fringes of the magnetically active planets deserves a new thread with a more juicyer title. This one seems to be repelling discussion like it has too much equal polarity with the local monopoles. Lol Anyone bother to look at...- silverslith

Graduate Production of C14 in the upper atmosphere
Obviously my brain slipped out of gear as I typed that. O16 + fast P > C14 + 3P Also possible may be : (natural abundance 0.366%) N15 + fast P > C14 + 2P (natural abundance 0.038%) O17 + fast P > C14 + He3 + P (or C14+ 2P +D) (natural abundance 0.2%) 018 + fast P > C14 + He4 +p (or C14 +...- silverslith

Graduate Production of C14 in the upper atmosphere
I guess my curiosity has been activated by other references to reversal of beta decay reactions in other enviroments. And I think that it is a valid point that the C14 stability before beta decay, halflife almost 6000years: is an unusually wide shelf. Perhaps not so unlikely to occasionally be...- silverslith

So you are weakly interacting with this question? Please clarify. Is there a strong interaction with other parties relevant to your response? ;-)- silverslith

Graduate Production of C14 in the upper atmosphere
I'm having some doubts about the standard idea of N14 + energetic Neutron > C14 + Proton. Is it possible that the generation of C14 could be a reverse form of the C14 beta decay to N14, initiated by the relativistic electrons entering the ionosphere in the auroras? An endothermic Electron...- silverslith
