Because you are working into an impedance which does not have significantly varying impedance by frequency when compared to the reactive components?

You could also say that it is less than optimal to have reactive components in circuit with a driver when the same job can be done at line level with more predictable results.

If you have a bit of DIY nous and want to dabble, the KMTech boards work well, I have used a set of the 24dB LR crossovers for the Ruark Equinoxes in my mancave system (and Tannoy 607s before that) and they work very well...

We have a cheapo Robert Dyas induction hob and at power levels below 1kW it pulses rather than sets a constant power as well. I suspect more money gets you more sophisticated power control.

Some different Easter music.

Should be stated that the trust I currently work for, along with all of the ones I have had as clients in a previous life, stick to the STPCD.

Presumably ratios of power to weight or space.

Big marine diesel engines are among the only ICE engines (bar F1 engines with energy recovery) that are approaching 50% thermal efficiency.

Just to put this in context, my church which is on the evangelical side of the C of E supports local refugees charities and is working towards the next level of the Eco Church award.

KMTech on ebay have some boards that are quite a lot less expensive than the Neurochrome stuff. https://www.ebay.co.uk/itm/114325427309?mkcid=1&mkrid=710-53481-19255-0&siteid=0&campid=5338728743&customid=&toolid=10001&mkevt=1...

This. They are an ICE car with a moderately more efficient drivetrain, a tech demonstrator for an electric drivetrain and nothing more. The whole point of a BEV or PHEV is that all or some of the energy used comes from electricity rather than directly burning stuff.

We do generally have at least one car at home (1 BEV, one PHEV) at any point so we will generally be able to use whatever solar we generate given hot water diversion as well. The only thing about the Zappi is that there is some fairly obvious functionality that could be put in around charging...

The myenergi Zappi does match charging rates to available spare solar but presumably that would mean replacing your existing charger.

No, he said next not current.

The best place for that is possibly the Carbon Intensity website, it shows predicted CO2 for -24/+48 hours with the ability to download data for chunks of 30 days going back to 2017.
