Sorry, not feeling up to it tonight...

So computers that are 16 and 32 bit were not effected.

A few reasons come to mind for why shadow is causing is as to how the single panels are wired internally as a wired orred (basically shorted together) which means the node currents are source and sinking to the same circuit wire causing the power to become low. If the segments are diode isolated that solves and causes the input to the MPPT that KBD512 has a loading issue such that the trigger voltage is being loaded down by its inputs.

Yes, seeing the articles now coming up including those saying that he should stop being president as well. That would give a few months for those that need to make up their minds on Pamela Harris as president.

The tank I believe is isolated and a small area heat exchanger is used to to do the transfer and expansion of the working fluid and its at that location the pressure rises and is allowed to flow to the means to make motion.

Have had the unpleasantness of passing a kidney stone yesterday evening. It sure was painful.

The monocrystaline solar are said to be the best performer with shade so one needs to see if the issue is at the panel joiner box or down the connection of the power wall.

Post is being made from cellphone as something is wrong with the hotspot for the computer. Still sick but somewhat coming out of it slowly.

That is due to the size of the power wall.

A use once system for the compressed air and water heated is about the same as driving an EV that the battery pack is made up of the common AA dry cells,

Installing solar panels over fish farms can help boost seafood harvests by 50%
The study looked at an aquaculture site near the mouth of the Yellow River in China's Shandong Province. In 2021, solar panels were installed several meters above the water to generate clean energy. The results have been astonishing.
The solar installation now generates 260 gigawatt-hours of clean electricity per year — enough to power 113,000 homes. At the same time, the shade from the panels keeps the water 3.6 to 5.4 degrees Fahrenheit cooler, which has led to 50% higher yields of shrimp and sea cucumbers.

For the moon one can modify the moon as the structure for Spin Launch SpinLaunch Vacuum Launches Centrifuge Launched Mass
will not be needed. Surely we can send heavy mass from the moon.
#15 Re: Home improvements » DIY pallet home building » 2024-07-07 14:17:45
The towns dump has 4 very long pallets that carried metal sheets for the new shed that was built on the site. I am awaiting approval to be able to get them. These would make a very good floor for the shed that I need to build.
As for the getting them home the car should be able to fit them just nicely.
It's a good question for those that do not have such available to do so on their own.
The Home Depot and Lowes have sleds that allow for material to be taken out of a store so something similar could be created to do just that from bike parts.

Atmospheric density and drag are a function of the shape of the nose. We know that atmospheric aerobraking has to do mostly with the diameter of the flat area of the heat shield so having a sharp shaped nose should reduce the heat and drag.

Repurposed technology used to probe new regions of Mars' atmosphere
To achieve this, ExoMars' Trace Gas Orbiter (TGO) teamed up with another ESA spacecraft orbiting the red planet: Mars Express (MEX). The two craft maintain a radio link, so that as one passes behind the planet, radio waves cut through the deeper layers of the Martian atmosphere.
Changes in the atmosphere's refractivity—how it bends the radio waves—cause tiny but detectable shifts in the radio frequencies received by the spacecraft. By analyzing this shift, scientists can determine the density of the lower atmosphere and the electron density in the ionosphere—a charged upper layer of the atmosphere. The technique is called mutual radio occultation.

Pressure treated wood such as those used where water is constant but not all are. methyl bromide is used in the treatment of pallets
seal the wood using a coating of polyurethane, wood varnish, or lacquer.
The treatment process makes the pallets immune to termites, rot, and decay. Before they are treated, the wood pallets are soaked in a water solution, which is made up of wood preservatives and other chemicals, which kills the bacteria and fungal spores on the wooden pallets.

A parabolic loop that extends from the surface vertically that is electrically charge would rise the field above the planet for sure.

Result in Plain English
5,000 miles per hour is equal to about 2,240 meters per second.
In Scientific Notation
5,000 miles per hour
= 5 x 103 miles per hour
= 2.2352 x 103 meters per second
Earth's orbital speed averages 29.78 km/s (107,208 km/h; 66,616 mph)

Electromagnetic field is a physical field produced by electrically charged objects
Gravity pulls along the 45% angle equally vertically or horizontally slowing it until the amount drops.
test flight details

previous tests that flew to altitudes of 30,000 ft (9,150 m)
https://en.wikipedia.org/wiki/SpinLaunch
The technology uses a vacuum-sealed centrifuge to spin a rocket and then hurl it to space at up to 4,700 mph (7,500 km/h; 2.1 km/s). The rocket then ignites its engines at an altitude of roughly 200,000 ft (60 km) to reach orbital speed of 17,150 mph (27,600 km/h; 7.666 km/s) with a payload of up to 200kg.
SpinLaunch conducted the first vertical test of their accelerator at 20% of its full power capacity, hurling a 10-foot-long (3.0 m) passive projectile to an altitude of "tens of thousands of feet." This test accelerator is 108 ft (33 m) in diameter, which makes it a one-third scale of the operational system that is being designed

https://bigthink.com/starts-with-a-bang … pinlaunch/
In order to successfully enter low-Earth orbit, a spacecraft needs to reach altitudes of around 300 kilometers (186 miles) with orbital speeds of 25,000 kph (16,000 mph), which implies much greater speeds and heights than SpinLaunch has been able to reach. To get there, the plan is to have the full-scale SpinLaunch system achieve exit speeds of 5,000 mph (8,100 kph), and to then have a working late-stage rocket activate to take the payload the rest of the way into orbit once it reaches a height of ~60 kilometers.
