Tesla Talk 2

What was the purpose of announcing that focus is on autonomous if nothing is going to change with regards to the private EV market? If the plan is business as usual then we could expect a refresh model for the M3 and MY. It's the fact he bothered to announce a shift from EV to autonomous that would suggest less on EV innovation, unless it is something specific to autonomy or a design feature that benefits a taxi fleet.

But it's all good for me for now with my face lift MYj and I welcome whatever autopilot improvements come from it. But I'm slightly concerned the company is spread too thin and the car design will stagnate. I'd hate this to be my first and last Tesla.

It might yet turn out that the one truthful thing Musk has said all year is that Trump is in the Epstein files 😬😀

178x earnings.
How long can bagholders realistically have so much hope in the future.

Low volumes traded today (considering a 9% fall) says it’s mostly retail sellers. Institutions expected everything in the financials, and they also learned nothing from musk to steer things up or down.

Id say it won’t drop much further on yesterdays results, there’s no momentum

You needn't worry too much about retrofitting insulation if your insulation is already reasonable with all the cheaper things done like attic insulation, etc. I've known people who got their windows replaced with triple glazed ones in their 20 year old home with double glazing, because they think they need it for a heat pump to work. It cost them €15k. It will give slightly lower bills, but the pay back is never never.

A heatpump will work fine in even an uninsulated house, but the SCOP will simply be lower

At the moment retrofitting heatpumps in Ireland (except when you DIY) makes little sense as gas / oil are far too cheap, they need to be heavily loaded with excise duty. With typical gas at 8c / kWh and typical electricity at 25c / kWh, even with a SCOP of 3 there is zero saving. And for people on the cheap night rates like myself, it makes even less sense. I can buy electricty at 5c and use it for heating. But I could instead sell it to the grid for 25c and use 8c gas for heating. The government rewards us for heating with fossil fuels, which is insane given climate change and even if you don't believe in any of that, just given the huge emissions fines Ireland is about to pay

Same here. We have the walls pumped and I'd love to go to a heat pump (and honestly I'd love to replace my existing setup with a few powerwalls but that's another story) but it just doesn't make sense. I've promised myself that if/when our 12-15y/o oil boiler gives up the ghost I'm not paying for another new oil or fossil fuel boiler.

But there's no real reason currently - financially - to switch from oil to a heat pump. Especially if you need to do insulation. We have 2 'sides' of the house, the main house and a 2 bed+kitchen+bath office addendum. The main house is well insulated but the office side needs new windows (wooden old double glazed) so I'd likely do that too. After spending 20k+ on solar, storage and some other related improvements when we moved in in '22 I can't really justify another significant spend yet (at least, without it being a necessity as in if the existing system gives up).

This is what people don't get, heat pumps don't 'not work' in non-insulated houses, they just won't be as efficient.

Don't even think about using an old degraded Leaf battery for home storage. Even if you can't DIY at all (as in you are incapable of assembling an Ikea flat pack), you can buy a complete 15kWh battery brand new on adverts for €2000. DIY as low as €900

I'm more thinking of - after what happened to me in my Tesla - imagine your old EV was written off and you got a few k from the insurance, you'd have a free storage battery!

It is the message that is delivered, presumably because installers want to make more on the top selling insulation etc.

If each kWh of energy spent to deliver heat was priced the same, heat pumps would be no brainers even at 2COP!

There's many of them, this guy sells a lot of them and seems well regarded

I could do it a bit cheaper for any regular in here. I would build a better system, using a superior JK BMS. But it would be a personal favour. I do them privately, mainly for myself and friends, it is not a business

That would not be a free storage battery. A better approach would be to sell the Tesla with that battery and then buy or make a brand new LiFePO4 battery for home storage

It really isn't that simple to use a high voltage car battery as home storage, nor safe in many cases. And the installers in Ireland that do these installs, ask for a lot of money to do so. Where a ready made battery is safe, lasts a lot longer and is simple plug and play (once a standard hybrid inverter is installed)

No, and only an electrician is allowed to enter a consumer unit to install a group needed for an inverter. That's why I said "once a hybrid inverter is installed". I do not do any of that. But I do build batteries, but just for myself and friends. Basically the same as that guy does, but he does it for profit / commercially. Even if you pay what he charges, you basically get a 15kWh battery of better quality than the 5kWh off the shelf packs that official SEAI installers install, for similar money

5kWh is nowhere near enough to be able to use the 3-4 hour supercheap night rates. As most people with fresh PV / battery installs very soon after install find out 😂

So because you don't go near the consumer unit, only the pre-installed inverter, you are within the law… Makes sense. I assume these are more than just plug and play units and requires an amount of disassembling/reassembling etc must have a look for installation videos over the weekend because that does sound interesting

Yeah definitely the 3-4hr window is nowhere near enough for me or my ilk, I have been saying exactly that to be fair!
