I commute on the northern line 3 times a week ... it's not fun, but it's bearable ... just. The trick is, if the window at the end of the carriage isn't open, make a beeline and open it, as the air moving past does help keep

Yep ... know people who commute on the Victoria and it doesn't sound fun. I've had to get it when my usual commute on the Northern line was impossible (only once, thankfully) and it was horrendous. And the Northern line is no picn

That's odd - I've got the Zappi and it works perfectly with Intelligent Octopus Go. Plug the car in, have a HomeAssistant automation that detects this and sets the "charge to add" on Octopus and enjoy the car being charg

I mean, it's a bit more than a contactor and an RCD, it also has PEN fault detection because TN-C-S is how most of us are wired up to the grid. Then for use with smart tariffs like IOG there's a microcontroller, cloud gateway for

Didn't Florida suggest using mining waste for road construction ... the kicker being that it's mildly radioactive?

It doesn't help that the official Tesla repair guide essentially says "Order a new side panel for the car, cut the damaged section from the car, weld in part of the side panel". And the side panel in this case stretches the e

Yep - the UK prescribing guidelines from NICE are eminently sensible as a way of staving off antibiotic armaggedon. One example of the guidance: https://elearning.rcgp.org.uk/pluginfile.php/199275/mod_book...

It already is on wholesale markets - in the UK you can get on Agile Octopus which gives you half hourly prices. When there is a glut of renewables on the grid you can end up being paid to use energy. This highlights the need for grid scale

I have an east/west array on my roof, as my house is positioned with the front facing west. In the winter it's outperformed by a south facing array (northern hemisphere) but in the summer the east array gets a ton of sun before mi

It often happens much faster than you'd think, and towards the end you're often on constant morphine for comfort.

You're often on a syringe driver of constant morphine towards the end in hospice care, either in patient, or out patient.

That was a difficult read for me - after watching my father die peacefully, and with dignity in a wonderful hospice I can't help but admire the doctors, nurses and other practicioners who dedicate their life to caring for people at the

I managed to get it to do just that. Interestingly, the share link I created goes to a 404 now ...

My mental model is saying it might do, much like on slow hard drives DoubleSpace in DOS slightly sped up loading data from disk.

and power density. They want you to be able to switch out the old mainframe racks for z17 racks and still stay within the same power budget.

by philjohn 1y ago
IBM advertise 8 nines of reliability for the z17 (i.e. a second of downtime per year). If you have a workload that cannot go down it's going to be more reliable than orchestrating a bunch of cloud servers where you're dealing with

They already send an email or push notification ... so yeah, there would be very little metric movement to justify this as having enough impact for year end PSC.

Not 100%. A lot in the US, for sure, less in the EU where renewables are a much larger part of the grid, as is Nuclear (thanks to interconnects from France). And if we work at it that number might go the same way as Coal has within our life

Try 2-300%.

Toyota have been researching hydrogen cars since the early 90's. Unless you can find a way to double their efficiency, and also get hydrogen down to close to 1:1 energy input to output it's just not an efficienct use of electricit

by philjohn 1y ago
Hydrogen that doesn't come from the natural gas industry requires that very same electricity to be extracted from water - so they're operating from the same baseline in my efficiency calculations.

by philjohn 1y ago
And much cheaper to fill as well. On a pretty efficienct ICE that I had I was averaging about 20p per mile driven. On my EV I'm averaging 2.5p per mile driven.
145.
by philjohn 1y ago
I’ve also gone for the max efficiency figures for the Hydrogen car. And that’s before we get to the fuel costs - £90 to go 400 miles in a Mirai, versus £5.50 to go 300 in an EV6.

Except it's efficiency for the same class of vehicles we're talking about, so a bike is an apples to oranges comparison. Proton Exchange Membrane is 40-45% efficient. Generating hydrogen from electricity is 70% efficient - meaning

https://www.sciencedirect.com/topics/engineering/fuel-cell-e... I believe all Hydrogen vehicles are using proton exchange membranes still, which have roughly 40-50% efficiency. And that's before you take into

by philjohn 1y ago
Yes - but Hydrogen vehicles have not proven to match or even beat EV's in a lot of key metrics that matter. The biggest one is efficiency. 40% efficient is one figure I saw, versus 80% for EV's. Yes, you can refill quicker, but ti

Is there now a section of the employee policies that forbids charging drones in the office?

It is expensive. I'm paying £40 a month for symmetric gigabit to my home, which is a house, in a suburb full of other houses, with no apartment blocks in sight.
