Yep, she sure was .. thats why you both share the bottom wrung of the ladder so well .. both idiots of equal lib-tard value ..

This is an example when a politician exposes her shortcomings, when she is not reading what a speechwriter wrote for her.

The sad part is that some people vote for politicians that do not articulate well and lack thoughtful substance.

She was burdened by what has been. Just the next in line to be the mouthpiece of Bobumba's fourth term. When the cows of the view asked her what she would do different from the third term .. she said I wouldn't change anything. That was one of many things that sealed her fate.

On the other hand, Trump is not a politician, he's a leader who speaks his mind. Like him or not, the whole world calls him daddy.

You can tell the battery lovers this all day long. To them, the end justifies the means. They simply turn away from the truth. They have made up their minds, and will not change them.

Their math is right. They are talking (correctly) about the HUGE tonnage (and associated costs) of mined materials to create grid-scale battery storage that only provides a couple of hours or power.

BUT

There is something more. Something very odd. As if battery storage for unreliables (wind and solar and their part-time nature), isn't nutty enough, there is this irrational drive that it HAS to be done by lithium. Why? Why lithium? OK battery storage is already HUGELY inefficient, takes up tons of space, and is fantastically complex and expensive. But of all the areas where you DON'T need the super high cost and fire danger of lithium, ground-based battery storage, (stupid wasteful and inefficient as it is), has got to be it. These things burn down like crazy because of lithium. If you've already got taxpayer backed, guaranteed profits for your wind and solar, and you really want ground based storage, stupid as it is, why not use something cheaper and safer than lithium? This mania over sticking with lithium with its high cost and high fire danger, even for ground based apps, is a big confuser to me. It smells of crooked politics rather than straight science.

My local plant went to gas turbines years ago. We also have a gas incinerator plant that kicks in some power. Residential price per kilowatt hr has been steady for a while. 12-14cts per kilowatt last I checked. If you use power off peak it's less. My monthly bill has been average of 95 -100 bucks for years. Less in mild months, more when the temps require ac or heat. But, never over 200 bucks. 3 br 3 bath 2750 sq. ft house and 1600 sq. ft. shop. with no ac or heat. Just for reference, hows your costs compare?

I can't talk about it!

You are an IDIOT, no question about that.

Well at least I know when I’m hitting home. But I can’t take credit for the laws of physics any more than you can break them, no matter how badly you want them to be something they aren’t.

Cudes mate, things would go a lot better for you if you would embrace the science instead of fighting it. And don’t take it personally. Science doesn’t care who you are or what your dreams and fantasies are. Science is not denying you just because it doesn't like you. It is however, absolute and unyielding.

For those of you that live and die by your politics, you might want to do a little check on which states generate the most wind and solar. The three wind farms I worked on were run by FPL. They're both viable supplementary systems. As for environmental impact, all forms of energy have their impacts. The real question is the ROI on the massive power requirements AI, not what is powering it. IMO

Why is this topic in general boating section, lol?

Why is this topic in general boating section, lol?

Because the maths and physics involved applies directly to planing hull boating, which is second only aviation, in need of compact energy storage and propulsion.

As to politics, it sucks that it is dripping with liberty grabs and corruption, but politics is smeared all over our lives, whether we have our heads in the sand or not. Everything from overpaying for boutique energy sources, to what kind of cars, boats, motorbikes we are allowed to buy, what we are allowed to do to alter them to better suit our needs, and when and where we can use them. Yes, it would be great if we could get politicians out of those things but I don’t see it happening any time soon. So the question is, do you want to live your life with your eyes open, knowing which politicians have which goals towards your liberties, or with your head in the sand, not caring?

From what I have read it generally takes about 13 yrs to start making a profit on a solar farm in FLA. Land costs, power storage batteries, power transmission lines, and sub stations not to mention man power to build, operate, and maintain them. We get 8% of our power here in FL from solar. So for the land use money outlay etc, not much of an impact power wise. It does make some people feel good though, and lots of income for others...

How many solar farms are in Florida?

As of August 2025, there were 205 utility-scale solar farms in Florida. Their total operatingcapacity is 11,846 megawatts (MW).

It's in the boating section because mister Knowitall from down under is a moron

Please go home, they need you there to fix everything,

A little bit of knowledge is a dangerous thing.

I’m going to hate myself for letting you lure me into re-stating the obvious, but it’s in the boating section because electric boating is a red hot topic around here. Also, you have been a red hot participant, (albeit mostly by cut and paste, and not by contributing your own knowledge and logic thought processes). The physics of electricity storage and generation as well as the terminology such as energy density, specific energy, the difference between power and energy, what have you, are all applicable to boating. In fact, they are essential to boating because of the high demands of planing hull boating. The same things that make lithium ion boat/airplane/car batteries into fire bombs, are the exact same issues that make lithium ion grid storage into fire bombs. The exact same issues that give you 20 minutes of planing time at 22 mph, with your 1000lb battery are the same reasons you only get a couple of hours of backup out of your grid storage for all that price and space and mining of millions of tons of raw materials. The. Issues. Are. The. Same.

Oddly enough, I had a ride in an electric boat a couple of weeks ago. It was a hydrofoil. The boat could go 50 mph or cruise 2 hours, but not at the same time of course. It takes more CO2 emissions to make an electric car than a gas powered car. The payback can take 2 years of daily driving. With the amount I use my boats, the CO2 payback would be never.



On the other hand, batteries continue to improve, so maybe one day



Interestingly, California is already using more battery storage than I knew. It would be interesting to see the cost analysis that led to this.
