I'd love to see the analysis supporting putting data centers in space. A data center on the smallish side is a 10 MW operation. The solar energy available in space is ~1400 watt/meter^2. Really good solar panels operate at ~25% efficiency. The maths say that's 28,000 meters^2 of solar panel, or ~70 acres! For comparison that is an order of magnitude larger than the array on the ISS (which is a fabulously expensive one of a kind). And then add the radio transmitter power to the 10MW. Not to mention it's going to be in the dark half the time so you actually need twice that much plus a big battery (with a limited cycle life) to get you through the dark passes. There are no tech fixes here either - solar panels are very mature tech and you can't change how much the sun shines. Edited Wednesday at 03:09 PM by gehringer_2 Quote

Think again: Trump administration will never support a power source that doesn't use fossil fuels. Those panels probably kill space birds. 1 Quote

Screwball Posted yesterday at 02:39 PM Posted yesterday at 02:39 PM More stupidity. From Seeking Alpha. I'll save you the click but here is the link; The Pattern Day Trading Rule Is Dead Quote Rules rewritten For the past 25 years, day traders of stocks and options in the U.S. needed to have $25,000 sitting in their accounts. If they didn't, they could only execute three day trades over a five-day period, while making a fourth trade would flag them as a pattern day trader and lock them out of their account. No longer. The PDT (Pattern Day Trading) rule is disappearing today—or at least most of it. Backdrop: The pattern day trading rule was implemented by FINRA in 2001 in response to the dot-com bubble. Active traders got hit hard during the downturn given the use of borrowed money, or trading on margin. New requirements were then put in place to fund their accounts in the hope of curbing excessive risk and speculative activity, as well as protecting brokerages from significant losses. However, critics have taken issue with the rule, saying that it was seemingly based on wealth rather than safety, and it was developed before the advent of zero-commission trading and real-time market access. Under the new system, the $25,000 minimum balance is going away, as well as the old rule that counted trades and the label of a "Pattern Day Trader." Instead, brokers will utilize monitoring infrastructure to look at the actual risk of open trades, and could block overleveraged ones or issue a margin call by the end of a trading day. It's also a massive win for fast-moving derivatives, as retail accounts can now rapidly buy and sell zero-days-to-expiration (0DTE) options. Existing margin requirements are sticking around, however, including the $2,000 margin base minimum, the 25% margin maintenance rule, and the restrictions associated with repeatedly failing to pay off margin deficits on time. Outlook: While FINRA is scrapping the PDT rule today, it is giving companies time to implement the changes across their systems. Brokerages like Robinhood (HOOD) and Webull (BULL) are jumping on the bandwagon immediately, though Charles Schwab (SCHW) is waiting until June 8, and Interactive Brokers (IBKR) and E*TRADE (MS) are set to make the changes soon, but haven't stated an exact timeline. Unlocking unrestricted day trading is set to be a tailwind for the companies' bottom lines, fueling fresh transaction volume that will translate directly into higher payment for order flow, margin fees, or premium subscriptions. No day trading rules, margin accounts, credit cards, Robinhood - what can possibly go wrong. Keep that bubble going at all cost. Who gets to hold the bag when the big kaboom happens? Quote

Screwball Posted 19 hours ago Posted 19 hours ago Can most people do anything about it even they wanted to stay away? I'm guessing not. Retail might get beat up, and good, they might be that stupid. The pigmen always win. Quote

Elon especially - has been the most long term successful purveyor of the 'greater fool' theory in my investment lifetime. His cult of followers will buy no matter what the fundamentals and no matter how outlandish the promise (nobody is going to Mars any time remotely soon - at least if getting back is to be included). And as long as they buy it all stays afloat. Like they say about shorts - the Market can stay irrational a lot longer than an individual investor can stay solvent.

The pigmen have to get everything all dialed in to make it look legit for the masses so they arb the rules once they let them on the exchange. They are going to make a killing anyway, but just more ways to suck money from the system. The smartest guys in the room. And besides, the IPO's are underwritten by the big banks. The 21 (not sure how many now - wow - looked it up - now 27) primary market broker dealers (the big banks) control everything anyway. It's good to be the King! Edited 17 hours ago by Screwball Quote
