It might happens eventually for new builds at least... It just did in the UK!

The CANDU still take a much larger space I guess due to the overall design. You can fit one of these SMRs in 10-15 acres.

He also said Canada is 'not a real country' so...

Oh sorry I googled CANDU to learn a bit more and saw that they were also made in a factory offsite.

I imagine that's at least one of the reasons why its lower capacity per reactor. It can only be so big if built offsite.

If there's any excess capacity (solar/wind/geothermal/nuclear/coal/natural gas), batteries extend it's usefulness and help manage any peaks better and can help you avoid building another generation facility for peak times. It also takes much less land than solar and with SMRs can in theory be brought much closer to population centers reducing transmission losses.

Edit: 300mw of solar would be between 1,500 and 3,000 acres of land. 300mw SMR could be as low as 10-20 acres.

Just buy batteries for the nuclear power plant as well. If you have to turn it off, you're making a mistake with our current tech.

At the lower end of the estimate, at least.

That will probably change for batteries as well as we come up with cheaper options. Lithium Ion ones can be expensive, but don't take up much space, but when you want grid scale, space isn't as big an issue. I have a lot of hope for the new Sodium Ion batteries. They're much cheaper, they just take up more space. Very new tech though.

All you need to counter the baseload though is a shit ton of batteries.

It's doable, but it greatly increases the cost vs just solar. Going that route would still be very competitive price wise when centralized.

Edit: And even the baseload of an SMR might want batteries if there isn't enough usage overnight, so they can use it during the day rather than building another SMR. So we want batteries regardless.

Ah, I didn't realize the CANDU's were also manufactured at a factory unlike the bigger built in place ones.

I guess it's just about getting them even smaller at that point, and the SMRs take up less land space as well.

A SMR-300 (maybe not this one specifically) can be as small as 3 hectares.

You're forgetting that the SMR provides a baseload, while solar would only provide during the daytime hours. You'd need to tack on a battery system capable of running the house overnight which would increase costs further by at a minimum another 10-15k with installation for a small single family dwelling, or build a more centralized MW level scale battery system elsewhere. Wind doesn't really work too well for residential as the turbines aren't as cost effective at smaller sizes. (edit: You'd also need to over provision each house in order to ensure there's enough excess capacity to charge the batteries for the evening, increasing the cost further, and ensure it is over provisioned enough for winter)

The article mentions that IF it comes in on budget, it'd cost around the same as a centralized wind/solar project which would be cheaper than a home system, but home systems obviously provide better national security in terms of not a single point of failure.

Also the goal of these SMR projects is to just churn these things out of a factory which will make them cheaper in the long run. These things are brand new, and saying lets just forgo this new tech because solar, which has had decades to get to it's current cost, are cheaper is a mistake. SMRs could very well be cheaper than solar in the long run if we put the effort into it.

Edit: And I'm not trying to say putting home solar/battery is a bad idea, it's also a critical thing to do. It's not one or the other, it's both!

Edit: Also unless it's on a standing seam metal roof or other similar snap on install roof, assume at least one likely removal/reinstall for the solar panels per lifetime of the roof which would add another few thousand dollars.

It's small compared to typical nuclear reactors which are usually 1GW, and these new units use much less land space.

Edit: They're also designed to be manufactured offsite at a manufacturing facility instead of the very large ones that are built on site.

The dual motor was originally announced at 50k

        Single motor rear-wheel drive with 250 miles of range, 7,500-pound towing capacity, and 0–60 mph capabilities in under 6.5 seconds, for $39,900

    Dual motor all-wheel drive with 300 miles of range, 10,000-pound towing capacity, and 0–60 mph in under 4.5 seconds for $49,900
  

You think a Tesla is only as good as top trim Corolla sedan?

Edit: To be clear, I'm not knocking the Corolla, it's a great car.

OP was talking about a 12k BYD vehicle.

If you want to get a similarly priced BYD you can get similar features, but in terms of that 12k car OP wants

A model 3/Y has

bigger battery (more range)

better sound system

more HP/Torque

more storage capacity

more airbags

multi zone climate control

bigger touch screen

I'm sure the list goes on and on. You get what you pay for.

Edit: I think the BYD Seal is the model 3 competitor in price/features.

I mean... if you want a 12k car you can have a 12k car, but don't expect it to be as good as a 50k car, even if the 50k car is only as good as a 40k car.

Edit: But also the new Y RWD is going for like 38k after rebates, so it's not even a 50k car.

Knock a wall down between them for a door and remove one of the kitchens, and now you have a 2 bedroom 2 bath condo with dual exits for an emergency.

If you can't move between units without going through a bedroom, make that a den or something and put a wall up in one of the 2 living rooms for the 2nd bedroom.

It might be a wonky unit, but it'd still be better than a shoebox

I guess that story a few days ago saying an attack was going to happen was true after all.

Oil and Gas forever, but also won't build local infrastructure to fully use it, and instead have to ship it elsewhere to refine it etc.

If it was him, I wouldn't put it past him to reuse emails for sockpuppets or other identities.

Maybe a Twitter leak one day will connect the dots if it really is him.

I don't know if any of them have actually gone through the whole process yet, but multiple states are trying to ban mrna vaccines
