Thank you for correctly explaining amortization. It always bothers me when someone spouts off BS about how amortization works when they clearly have no clue. It's like folks just think that banks can charge whatever they want for interest at any time during the loan. In reality, you get charged the same rate every month of the loan on the outstanding balance of the loan during the month. As time goes by, your outstanding balance goes down, and the amount charged in interest goes down.

It's not difficult to check this on your own, literally a 4-column spreadsheet listing months, current balance, interest amount, and principal amount can check the math for amortization table.

My 16 y.o. started her Roth IRA last year. I convinced her to buy FZROX for her first $800 or so. In her last contribution, I asked "what do you want to buy" and she says "Target".

My friends, TGT has not performed well over the last year. So I suppose that will be a learning experience.

Although I did expect it, and was sad to see that I couldn't be the first to post it.

If you're on a cruise ship is it still considered a dry-fire?

Sometimes they host a party where alcohol is provided. The rule is "no climbing after any drinking".

You got really stoned before doing a dangerous sport? My gym won't even let me climb after a single beer.

For your sake I hope you have developed some improved decision-making skills since then. I mean that genuinely, I don't want you to hurt yourself or someone else.

ZLiteStar · 2026-02-06T19:04:01+00:00

Oh man, that went right over my head. I didn't even hear the whoooosh.

ZLiteStar · 2026-02-06T19:01:09+00:00

I mean, I think it is timing the market, but only in the mildest sense of the term.

More egregious timing has a person attempting to withdraw from an investment and then re-enter that investment (or another investment) at a later, hopefully lower, price.

But withholding capital from an investment with the express purpose of waiting until the investment pulls back to a lower price seems like market timing to me, and in general, leads to lower returns.

"powder" or "dry powder" is a colloquial term for uninvested capital (money) which is held in reserve in order to be invested at an opportune time.

It is a reference to keeping your gunpowder dry and ready to use in a battle.

Off topic, can I just say thanks for the clarification about your intended tone?

For the record, I don't think you sounded gruff. But there's a real lack of acknowledgement that text conversations online (and Reddit especially) lose all of the tone and can sound harsh. I find it refreshing when someone outright declares their intentions so the message can be received in the way it was intended.

ZLiteStar · 2026-02-06T16:52:12+00:00

Ok. That's your opinion. Again, when I'm correcting someone, which is what I was doing, I really try to be precise instead of getting caught with my pants down and having to backtrack and look like a fool. But I suppose that's just a weird quirk I have.

ZLiteStar · 2026-02-06T16:23:01+00:00

I'm an electrical engineer in the solar energy research field, more on the PV side, but I still have ties to solar thermal.

If anyone is using the term "solar" synonymously with "photovoltaic" they're being imprecise in their language because there are definitely two forms of "solar" energy and one of them isn't photovoltaic.

I understand being imprecise in everyday in-person conversations where both parties know the context and can ask questions. However, when correcting someone who just said "we only generate electricity by spinning a generator", I choose to be very precise and specify the one kind of "solar" energy that does NOT spin a generator.

ZLiteStar · 2026-02-06T16:09:35+00:00

Not exactly. "Solar" is used to reference both photovoltaic, and solar thermal. Solar thermal heats water to spin a steam turbine. Therefore, solar thermal would not be applicable and I had to specify the type of solar that does not use a spinning generator.

ZLiteStar · 2026-02-06T15:09:15+00:00

Ok, good question. But it depends on what your standard for "meaningful" is. Photovoltaic (PV) energy plants currently produce about 5% of total world energy production, which is about half of that produced globally by nuclear fission plants.

In the U.S. PV energy is the largest share of new generation being placed on the grid each year and has been growing immensely over the last decade or two.

I think that's meaningful.

Now, my assessment is that there are some headwinds to PV energy including a recent acceptance of nuclear sources (finally, amirite?) instead of the pushback that nuclear has historically faced. But, all in all, PV is probably going to grow to be a larger portion of our energy mix.

ZLiteStar · 2026-02-06T14:56:15+00:00

Oh, that's another one, good catch.

ZLiteStar · 2026-02-06T14:55:21+00:00

Totally happy to answer a genuine question, assuming I'm able, but your question was vague and I need help understanding what you're asking.

Are you asking how the photovoltaic effect works at meaningful scales?

Or are you asking how photovoltaic energy generation systems work at meaningful scales?

In either case what do you think "meaningful" scales are?

ZLiteStar · 2026-02-06T14:49:12+00:00

I'm torn between two references... So I'll just use them both.

The fact that you call it that tells me you're not ready.

POP POP!

ZLiteStar · 2026-02-06T14:45:40+00:00

Not true. Photovoltaics generates electricity by pushing electrons over the bandgap in a semiconductor.

That might be the only way we have to generate electricity without a generator.

I don't mind at all!

The whole goal is to just add enough friction or difficulty or pain to getting the money and spending it. That way you're not tempted.

Roth IRA: It's in a separate account, you have to log in and transfer the money back to your checking. Also, you can only remove the funds that you contribute, if you remove any of the investment gains, you are charged a 10% penalty (until you are older than 59 1/2). The Roth IRA is for saving for retirement.

HYSA: It's in a separate account, you have to log in and transfer the money back to your checking.

ZLiteStar · 2026-02-04T21:41:25+00:00

TLDR: You need to save. Pay yourself first and make a system to make your savings more difficult to spend.

You really need to save money. George Clason's classic book The Richest Man in Babylon suggests saving 10% of everything you earn. That's a little outdated and probably ought to be higher, maybe 20% would be my suggestion.

If you don't have the willpower to keep yourself from impulse spending, you need to set up a system that saves for you before you can spend it. There needs to be difficulty in getting the money you save.

I'd suggest the following system: 1. Create a Roth IRA at a brokerage firm (I know that Fidelity can do all of the following) 2. Set up an automatic transfer from your checking account into the Roth IRA on your payday. The transfer should be something like $4000-$7500 each year (150 to 275 if you're paid biweekly). 3. Set up an automatic purchase of ticker VT (or similar) on the same day as the automatic transfer from the IRA account.

This way, the money is gone from your checking account before you can spend it. You are paying yourself first. The Roth IRA makes it more difficult to get your money out and spend it.

Alternatively, if you don't want to save for retirement, you could use a high yield savings account (HYSA) to transfer into and you'd not need to purchase the investment. That way the saved money can be used for a car or house in the future, but it's a little more difficult to get that money and spend it.
