I wonder how many miles are on the final motor after Tesla figured out what the design issue was. Nice to get the stat that battery pack is $10k and good for 300k miles.

Sounds like the manufacturer just wants to ship palettes of the product to amazon and not deal directly with individual customers and are happy to have amazon make their markup for the service they provide.

The “fibre bearer” term that GP comment used does not imply OPGW

I have seen Lashing fibre to power conductors and it was a bad idea. The conductors sag when heavily loaded on hot days and the lashing digs in to the fibre jacket.

For some company to get financing to build a battery it requires some certainty they will not go bankrupt, which means a contract with someone than ensures they will make money. Gambling on the arbitrage opportunity in electricity market rates alone isn’t going to get a 100 million dollar loan.

The last line of your comment is the most interesting to me, electricity is more expensive than ever in Australia.

RIP your home insurance

The difference in the cost also needs to be enough for people to care. If it costs 25 cents more to get the laundry done now instead of later in a world where a head of lettuce is $4 I am just going to do the laundry when it is convenient for me.

The major loads such as heating and cooling people Also want them immediately and not later.

Are the raw materials that much cheaper in China? I hope there is more than $4k worth of materials in any vehicle I drive or how long can it last?

What negative outcomes do you foresee? Surely they will build the first tower, ensure it is adequately utilized, then build the next one etc?

It’s not a realistic hourly rate given the overheads tradespeople have for things like insurance. Where I live a plumber is $135 for the first half hour and then $135 for every hour after that. Canadian dollars. When the phone rings off the hook at that rate who is going to bother with a $20 job.

You shouldn’t do electrical work on someone else’s house. If it burns down and electrical is the cause as an unlicensed uninsured electrician you are going to regret that $20 you made.

Coding a web page for a neighbour is different since there are often no ramifications in the physical world if it doesn’t load or look exactly as desired

> Solar inverters can produce/absorb reactive power easily

> Solar and wind systems today typically do not have a voltage setpoint or control loop. That's because there is no big gas/steam valve to adjust the amount of power generated. The operator wants to inject all the power from the sun/wind into the grid, whatever the voltage.

reactive power being easily controlled is the same as a voltage control loop with droop when connected to a larger system.

Control of the traditional prime mover by way of devices like steam throttle valve controls real power (MW) and not voltage or reactive power (MVAR).

I am curious how an inverter operating away from unity power factor fails to deliver roughly the identical amount of energy as at unity. Can you provide a link that explains it? Traditional generators pump out the same MW barring losses due to increased current no matter the power factor. MW in mechanical * efficiency = MW out electrical. And of course there is a limit to how out of phase the voltage and current waveforms can be, usually +/- 0.9 pf.

A 60Hz cycle is 16.7 ms, A 13 kV breaker takes 80ms to open, to detect a fault (except for differential element) let alone clear it takes a lot longer than 20ms.

In the case where a system splits and one area is 6.3 GW in deficit how is an inverter going to conjure up that power?

The only thing that can help in that case is batteries.

98% of the power plants I’ve been to run the voltage regulator in voltage control mode with 5% droop. Solar and wind farms can do that too, and I am sure it is required by the system operators to allow them to connect.

If grid operators want more or less reactive power they call us and tell us to change our voltage setpoint on our plants. Can’t they do the same with solar and wind? The grid operator does not need real time control of the setpoint since the control loop responds in real time.

The market operators always need people who can help make sure the market is operating correctly and that market power is not being abused

Getting any waves in BC or alaska?

For frontend display and reporting, or cases where human life and the environment are at risk if there is a misoperation?

In New Zealand they were remotely controlling residential customer hot water tanks and heaters with energy stored in hot oil using a “ripple” signal on the power lines … probably in the eighties by the age of the equipment I saw.

The variability of wind/solar can also be handled without time of use pricing by the grid operator including terms in the energy purchase or interconnection agreement requiring the generating facility to maintain some degree of consistency to the output. Then it is up to the generator to figure out how to do that, perhaps with batteries.

The problem we saw in Ontario when the market was introduced in 2001 or so was that it was politically unfavorable to have the extremely high prices, even for an hour let alone long term, that would encourage an investor to build a storage facility.

Do aluminum factories shut down daily due to fluctuating prices or are they located in areas with cheap and plentiful reliable electricity supply?

What factory that produces X is so cheap to build in relation to the cost of energy on a daily basis that it is worth producing less X at different times of day due to the price of energy? The cost of the energy is usually such a small component of total costs it is not worth altering behavior for daily small energy price fluctuations, and nobody is advocating for energy prices to change by 10x throughout the day.

If someone breaks in to the locked filing cabinet in my house I have bigger problems than 1 factor being compromised

Bank of New Zealand and Canadian government both issue a 4x4 grid of three character codes and ask for some of them when I login to online services, this proves the “something I physically have” component of the authentication. I have the grid either on a card or printed off. I like that it doesn’t depend on a phone.

>The crabs likely died of starvation as a consequence of marine heat waves in 2018 and 2019

It’s 1.4 acres 3 minutes from all the amenities of huntsville which I see has a hospital, multiple community swimming pools etc. the house has two kitchens so easily you can rent out a suite.

The house is not in the middle Of the lot so you can Sell half the land.

Honestly looks like a good buy from where I’m sitting in BC.

Go Build a house and take advantage of the high prices!

Is it adequate for you?

I didn’t mean to denigrate cleaners, I have friends who clean air bnbs and they are charging more than $45/hr, I just saw that advertised. Anybody can pick up $50 worth of cleaning products and start scrubbing without any special education or training so we might disagree on how much skill is required, but my Airbnb cleaning friends definitely have motivation, and a positive attitude and outlook on life despite the challenges they face in other areas.

Either you rent for your whole life or you buy something and have to compromise on some of the variables. I see lots of people working hard, mostly in jobs they don’t love, and making those compromises and choosing to buy somewhere.

> despite literally not having a job, any prospects, or the possibility of owning a home at any point in my life, even as a software developer

I hope things turn around for you! I meant to point out that home ownership is possible, but it sounds like you have already evaluated the variables and if you are set on only living in some specific area then home ownership might not be possible in that location without a couple of well above average incomes.

I think mortgage brokers were a bit more flexible than the big banks at recognizing future rental income, especially if you already had one property generating some rental income indicating you would probably make it work again.

For the first property I agree you would need to qualify without taking the rental income in to account.

I meant brailsafe’s share of the down payment is 90k, and brailsafe’s partner would also have to come up with 90k. 20% down. Agree 10% down is not plan A.

Also agree on the banks being difficult to work with on including the future rental income when qualifying.

It sucks if you are a single person - probably have to go apartment route or 1 bedroom condo. The most successful guy I know, who has a pretty sick motor yacht now, had a room mate until his now wife moved in.
