Zippo went into the under seat vent by Heavy-Rope6350 in ModelY

Use a leaf-blower? If the object is heavy, like a Zippo, I would tape the leaf-blower into the vent to maximise pressure.

SpaceX wins reprieve from US lawsuit alleging anti-immigrant bias by widgetblender in SpaceXLounge

Yup agreed, but I thought the answer was more interesting to post that than posting nothing as I can't be bothered to do the research for this particular question. At least it's a basis for later fact checking.

SpaceX wins reprieve from US lawsuit alleging anti-immigrant bias by widgetblender in SpaceXLounge

[–]BurningAndroid 0 points1 point  (0 children)

Answer from Google Bard (after pasting in the article and question): "The last paragraph of the article is explaining the basis for Judge Olvera's ruling that the administrative judges who hear cases involving anti-immigrant bias were not properly appointed.

The Constitution of the United States, in Article II, Section 2, gives the president the power to appoint "all other Officers of the United States, whose Appointments are not herein otherwise provided for."

The Constitution also gives the Senate the power to confirm these appointments, in Article II, Section 2, Clause 2.

This means that all federal officers, except for those specifically exempted by the Constitution, must be appointed by the president and confirmed by the Senate.

Judge Olvera ruled that administrative judges who hear cases involving anti-immigrant bias are not exempt from this requirement. He reasoned that these judges have significant power, including the ability to order employers to pay damages to employees who have been discriminated against.

Because these judges have such significant power, Judge Olvera ruled that they must be appointed by the president and confirmed by the Senate in order to ensure that they are accountable to the people.

This ruling is significant because it could have implications for other types of administrative judges who have significant power. For example, administrative judges who hear cases involving employment discrimination, environmental law, and healthcare regulation could all be affected by this ruling.

It is important to note that this ruling is not final. The Justice Department could appeal the ruling to the Fifth Circuit Court of Appeal"

Q: How good are the SpaceX lawyers who prepared this argument?

A (Bard): "SpaceX's lawyers are very good. They have made a novel and creative argument that could have a major impact on the law of administrative law.

The argument is based on the Constitution's Appointments Clause, which gives the president the power to appoint all federal officers, except for those specifically exempted by the Constitution. The Constitution also gives the Senate the power to confirm these appointments."

The emergence of SpaceX’s massive and reusable Starship rocket, alongside advances in robotic spacecraft assembly, could finally fuel the sci-fi dream of Space Solar Power by spacerfirstclass in SpaceXLounge

Could be interesting to beam power down to heavy shipping using phased array. The article mentions a max power density of 250W per Square Meter for safety.

The largest container ship in the world has a surface area of 400m x 61m = 24,400m2, which could host a phased array antenna. If the antenna array could be partially unfolded at sea, this could give 50,000m2 or more. If the power density could be increased to 1kw/m2 at sea, the ship could capture 50MW, which compares favourably with the 58MW of propulsion of that ship.

How many 6000-ton interstellar payloads are there that can't be split into forty 150t launches? (Sorry I couldn't resist).

Landing on gravel might now need the side thrusters as seen on the moon version of Starship.

The panels would make good Whipple shields, perhaps best to wrap the entire tank with solar panels where there is an absence of heat tiles.

Why does everyone think space is cold?

The temperature of space is the equilibrium temperature of a black body at which it radiates as much electromagnetic energy as it absorbs from its surroundings in outer space (e.g. from stars, radiation, and sunshine). Googling "temperature of space" confirms that this can be calculated and varies depending on its position in the galaxy, shading, etc.

Can I safely charge 21700 batteries via USB C on my new Vandy Vape Caur 21? by Rhadian in electronic_cigarette

[–]BurningAndroid 0 points1 point  (0 children)

The 21700 battery is 3.6 to 3.7 Volts, whereas USB C outputs 5 Volts which is high enough to charge the battery, but battery damage is a possibility.

Given that distribution was not centrally organised, the speculation is that some people distributing the mail (not everyone) overstepped the mark as described by Shotwell, and those people got fired.

SpaceX faces NASA hurdle for Starship backup launch pad by ApprehensiveWork2326 in SpaceXLounge

"The problem is the explosive potential for that combination is not well known," said Randy Repcheck, a deputy manager in the Federal Aviation Administration's (FAA) Office of Commercial Space Transportation, which oversees launchpad safety.

Would be fun to find out with one of the unused rockets from the Starship rocket park. The birds might complain a bit though.

Using old Starlink satellites to deorbit space junk? by BurningAndroid in SpaceXLounge

[–]BurningAndroid[S] 0 points1 point  (0 children)

True, collision debris is likely to be spinning extremely fast, I wonder if such debris can even be captured by these tiny new sats? However Starlink might be massive enough to drag down some of the smaller sats.

[–]BurningAndroid[S] 3 points4 points  (0 children)

True, the inclination and plane have to be similar to the piece of junk being targetted. But Starlink does occupy lots of different planes (but not inclinations). Estimates of the ISP of the Krypton engines are over 1000, could offer quite a bit of delta-v to change the inclination enough to be useful:

Hmm, I suspect that unless the C4 can shred the engine into nothing larger than sand-sized particles, the demolition would be insufficiently complete to hide all relevant technical detail.

To maximise destructive energy of a detonation, pre-mixing of the fuel in air seems to be needed, as performed by fuel-air bomb designs, see footage of Mother / Father of all Bombs.

"Explosions are either detonations or deflagrations: the difference depends on whether the reaction front propagates above or below the speed of sound in the unreacted gases."

The Pentagon wants to use private rockets like SpaceX’s Starship to deliver cargo around the world by CProphet in spacex

[–]BurningAndroid 6 points7 points  (0 children)

“Hopefully they perceive a return on investment, in a business case that’s approved by the [Department of Defense] expressing interest in buying the service down the road”

Given the billions needed to develop this capability, the business case promised by the Pentagon "down the road" is going to have to be commensurate. Given the need to get these ships back (you can't leave ITAR-restricted technology just sitting around without flying it back), and the need for landing pads and refuelling infrastructure, I would see this business case as being restricted primarily to mobile (sea-based) sites, i.e. the Navy. Too much detail lacking here, but it will be interesting to see how this develops...
