Meh, Lidl sells 3200w kettles.
Where are the three phase models?? Seriously though, a 15A kettle sounds great.
I started with:
sqrt(1-((1/(1+120 PeV / (neutrino mass * c^2)))^2))
120 PeV to 120e15 * 1.602176634e-19 kg m^2 s^-2
neutrino mass to 1.25e-37kg
speed of light to 299792458 m/s
0.999999999999999999999999999999999999829277971
If you want details about the way this is calculated, I dug up the formula from an article I'd written about particle velocities in the LHC, back in 2008[2]. For comparison, their 7 TeV protons were going at 0.999999991 × c.

For context, 120 PeV is about 10% the kinetic energy of a ping pong ball during typical play.

Oddly another detector caught a burst of low energy neutrinos that came a few hours before the burst that everyone accepts was from 1987a https://www.sciencedirect.com/science/article/pii/S092765051... Low energy tachyons would go a little faster, but you've got the additional problem of explaining why neutrinos got emitted in a spectral line.
That is weird. Is the conventional explanation a flash from one of the last fusion stages right before core collapse?
It took a few tries, but I got Wolfram Alpha to compute its velocity compared to the speed of light[1]. I started with: sqrt(1-((1/(1+120 PeV / (neutrino mass * c^2)))^2)) but it simply said "data not available". So I changed: 120 PeV to 120e15 * 1.602176634e-19 kg m^2 s^-2 neutrino mass to 1.25e-37kg speed of light to 299792458 m/s and finally it gave a numeric result: 0.999999999999999999999999999999999999829277971…

Neutrinos “interact with regular matter so rarely that it's estimated you'd need about a light-year of lead to completely block a bright source of them. Every one of us has tens of trillions of neutrinos passing through us every second, but fewer than five of them actually interact with the matter in our bodies in our entire lifetimes.” They have 1/500,000 the mass of electrons. They interact only through the super s…
These rare interactions with matter are also a cause of concern in voting machines, right? Or at least it was a concern at one point. A random bit being flipped or something.
But the main source is from cosmic rays and local radiation sources in the ceramic packaging and/or decaying elements in the metal frame/leads/solder.
