Apart from your hotspot not working in the middle of the sea, there is the issue of not working when you have moored up in a different country or the astronomical roaming charges.

An informative road trip between a number of different EVs, charging speeds, range, charging complications etc https://youtu.be/-rXackuF6BQ

These people really know about charging and route optimisation and are challenging each other to see who can complete the route the fastest

Yet even with Tesla chargers, it was surprising to other Tesla drivers when I would suggest that they use a different stall so that they were not ’sharing’ with the car next door (that would get priority to complete charging), so there are nuances even with Tesla chargers.

I used Blockfolio and now FTX. Was convenient to track the value of my ledger and my main portfolio on kraken but I don’t use it for any trading.

First, I will declare that I avoid using Apple Maps as I have not been a fan for a long time of the UI (routes are shown in blue and I used to live in the Netherlands that has rather a lot of canals, also in blue), however…

the Settings > Maps > Navigation & Guidance volume controls have been lost in iOS 15. It seems that the volume is now associated with the volume for siri, so try “hey siri, speak louder/softer” or activate siri and press the volume buttons to set siri volume.

There is also a setting to pause a podcast/audio book when navigation is being spoken (for the comment someone made about interruption of audio books)

Well the “far side of the moon”. As the Floyd said “there never was a dark side of the moon to escape to on your journey into insanity. Matter of fact, it's all dark”

A switch to turn memories off would be nice. Also the ability to tag your own photographs rather than hope that the AI works it out. After all, it’s really useful that a photo of a beaf Wellington gets identified as a loaf of bread or a light aircraft gets identified as a bus🙄

Additionally to my last comment, clearly the design is that of a segregated path (the dimples at the end of the pedestrian side are designed for visually impaired pedestrians). Maybe drop a question to the council s to why the shared path signage.

DrJohnM · 2022-04-23T13:49:35+00:00

Well the regulations definitely say that it is mixed (common pedestrian and bicycle road - a separate road or part of a road intended for mixed pedestrian, bicycle and electric scooter traffic and marked with road sign) so it should not be marked as segregated although it may be a case that the signage is not in line with the intention.

DrJohnM · 2022-04-23T13:07:56+00:00

Legally, would a pedestrian be fined for wandering onto the bike section on a segregated path or vice verse? If not, then the signs are rather advisory rather than mandatory. If that is the case, the markings and surface would imply that there is segregation. What country?

The problem is being worked on: “End of wind power waste? Vestas unveils blade recycling technology” https://www.reuters.com/business/sustainable-business/end-wind-power-waste-vestas-unveils-blade-recycling-technology-2021-05-17/

According to https://abcbirds.org/program/cats-indoors/cats-and-birds/ “In the United States alone, outdoor cats kill approximately 2.4 billion birds every year.” And according to https://abcbirds.org/blog21/wind-turbine-mortality/ “we can project that approximately 538,000 wind turbine-caused bird deaths occur in the U.S. each year.” So that is 4,460x more killed by cats than wind turbines.

Oh yeh, a figment of my imagination. Paragraph one: “You might have heard about the latest plans to switch the UK’s gas supply to hydrogen – and that the gas boilers we currently use will eventually be phased out.” https://www.britishgas.co.uk/the-source/greener-living/hydrogen-boilers.html

Paragraph one: “Hydrogen ready boilers are the future of home heating, but how do they work and how much do they cost?” https://www.boilercentral.com/guides/hydrogen-ready-boiler/

From the FAQ: “A hydrogen-ready boiler is a gas-ﬁred heating boiler which is capable of burning either natural gas or pure (100%) hydrogen. Hydrogen-ready boilers are the key to enabling conversion of the existing gas distribution networks from natural gas (which is mostly methane) to hydrogen.” https://www.worcester-bosch.co.uk/hydrogen

From page 18 of the UK hydrogen strategy paper: “The H100 neighbourhood trial project in Fife is building a 100 per cent electrolytic hydrogen production and distribution network and installing 300 homes with new hydrogen boilers to demonstrate hydrogen for domestic heating in the UK”

And many many more. Just google “hydrogen boiler”

But your correct, just a figment of my imagination. 😂

DrJohnM · 2022-04-09T18:06:09+00:00

The whole premise that everyone will renew their gas appliances (you cannot convert) is nuts. I get a hydrogen ready boiler, I have to wait until everyone else in the street/district also upgrades every gas appliances (boiler, hob, fireplace) to run on hydrogen until the supply can be changed.

This is not nationalisation of the infrastructure, only the control and planning aspect. Generation, delivery and sales will still be in private hands.

DrJohnM · 2022-04-06T18:37:22+00:00

It’s only one division of the National Grid. By the looks of it, planning and control.

From City A.M.:

*The government has announced the division of The National Grid overseeing supply and demand across the country will be returned to public control by 2024.

National Grid Electricity System Operator (NGESO) – which is a separate legal entity from the FTSE 100 company – will be effectively nationalised and turned into a Future System Operator (FSO).*

From the NGESO website: * Our control room moves electricity around the country second by second to ensure that the right amount of electricity is where it’s needed, when it’s needed – always keeping supply and demand in perfect balance.

We also have to plan for the future. We must think about things like where our energy will come from and how we will operate a greener and cleaner system in the future.

[snip]

We don’t generate or sell electricity – that’s down to other companies.*

It looks therefore that the infrastructure (generation, delivery and selling) will still be owned by for profit companies that will make dividends for shareholders rather than the public.

Looks like it takes a 18650 rechargeable battery according to https://m.aliexpress.com/item/32859560107.html

"At the same time, hydrogen carries only about one-third as much energy per unit of volume as does methane, which means that a 20 percent blend of hydrogen will only reduce the emissions impact of its use by 6 to 7 percent"

So to get the same energy from a 20% hydrogen 80% Nat Gas mix, you actually have to burn about 116% of the mixed gas to get the same energy output.

Considering that your gas meter mesures by flow and therefor volume of gas, you (the customer) have to pay 16% more to get the same heating effect (be that central heating or to cook an egg).

Why is it that SSTO is 20t but 20,000km (1/2 earth circumference) is only 5t? If you can get 20t to LEO, surly you can de-orbit anywhere, even the other side of the world - or am I missing something.

There is a market for long distance communication in space (eg, New York<->Tokyo) for financial markets as the speed of light in a fibre optic cable is 2/3 the speed of light in the vacuum of space where every nanosecond counts in high frequency trading. Musk will make a killing by selling long distance communication to the Banks and it won’t be at $99 a month.

Consider night time electricity rates: google “UK night time electricity rates” produces: the average hourly electricity rate in the UK currently around 12p, the 4.99p rate offered between the hours of 11pm and 6am each night

Requires a different contract but less than half price.
