It doesn't particularly matter what it maxes out at if the utilisation over time is much lower. e.g. a spike loading a new texture set would potentially have to wait 4 cycles rather than 1 but if there isn't another texture set waiting to be loaded after it's a small hit on performance.

The main bottlenecks for modern graphics cards aren't usually the PCIe lanes. As I put performance tests show it's about a 20% hit on a desktop class card with current games. Before eGPUs existed similar tests were done with GPUs running on 4 and 8 lanes with similar results. The result will vary by game, texture volume and the cards memory. The more memory the card has the less it will use PCIe.

For the future Thunderbolt 5 will be 80Gb/s uni-directional or upto 120 bi-directional so it will be even less of an issue. PCIe 5 will be a similar increase but again is likely low utilisation over time.

Razer Core X and similar eGPUs seem to do ok. I have seen a RTX 3080 rated at about 20% slower than on a desktop. Slightly better if you don't have to return the graphics output back down the thunderbolt connection. A large amount of memory on the cards can certainly help with the bandwidth. I can't really see it being an issue for most graphics cards when heat will stop them first in a laptop.

I'm pretty sure condenser boilers are more efficient (94% for a new one). The radiators are on a separate loop not combined with the hot water system so you don't need human consumption rating.

Most modern houses in the UK use a "combi" boiler. That's a radiator loop heater and tankless hot water system in one. It heats the cold water feed direct for hot water on demand but that does mean a supply limit. Advantages are no efficiency loss through hot water storage, no space loss for the water tank, no legionnaires or similar concerns.

The other common type is a tanked system. Again the boiler does all the heating but in this case either feeding a hot water tank or the radiators. Hot water tanks are more common in older properties, those with pressure issues or those with too high demand for a direct feed.

We will probably be going back to tanks as we are slowly moving towards heat pumps from gas boilers.

How much are you getting rid of? Can't you just take it to the local tip?

Also if you put an advert on Facebook or similar for free hardcore someone will take it.

I don't think you could detect the force direction quickly enough to do that.

On a static phone you can detect down using gravity. When the phone is potentially spinning and moving in any direction you can't as easily separate the forces applied from the phone motion. Essentially you get an output of forces in 3d but it isn't tied to a direction directly.

Yes I think it's still a 50 years away technology. SPARC looks promising with its magnet technology and small size (so I assume less tritium).

The target Q factor is 2 but it could be as high as 10 which is atleast approaching a real net gain. We probably need a much larger q factor to make it a viable power source though. Wind, solar and other renewables have become really cheap.
