Lock out, tag out; and prove test prove. These are the simple rules that will keep you alive.

Volcanic sulphur isn’t that bad, you get used to out petty quickly.

Some very still mornings it I can be quite strong…

True

This.

Bloody Aussies stole out shitty design.

I’m not sure why you are getting down votes.

The reasons fur the demand sick, but you are correct, demand is fast outstripping supply… Price rises are inevitable.

I’m conflicted.

As an “enemy” of Putin, I have to assume assignation, but no windows? Russia has lots its way, are the classics no longer respected.

Probably from the chemical properties; very unlikely from radiation.

Reading through this. There are plenty of carcinogenic chemicals such as arsenic, beryllium, cadmium, chromium, cobalt…

What the hell; light bars, these are critical…you will never be afraid of the dark again with 1,000,000 lumen light bars.

I was hoping to day this same thing.

My now 10yo loved all the Enid Blyton books a few years ago, especially the famous 5.

I use windows at work, I have local admin which removed a lot of friction for a more technical user.

But the difference between my home machines (18 years Linux) and my work machine is friction. Windows makes things hard, it is always a few extra clicks or a stupid reg key change.

E.g. recently wanted my full right click menu back on win11, no nice setting option. Go edit this unnamed registry key, it seemed so janky in a modern os.

I’m a long time Mint user, jumped around a fair few distros but mint works well for me. It is so polished compared to windows, it seems crazy it is the free one.

No it isn’t.

Oil can be pumped at atmospheric pressure and temperature, it is a little easier to warm it a bit, but not a hard requirement. This is easy to work with.

Electricity is easy to work with, it will stay in the wires and can be switched on and off in milliseconds.

To work with hydrogen, you have to either compress it a lot, or liquefy it. Both have significant challenges.

For example I was working on a hydrogen pilot project, we were using 700 bar compressed hydrogen as the storage mechanism. Getting the compressed gas out of storage was always a pain in the arse, valves would freeze open causing control problems. Perhaps physically larger valving wouldn’t have this problem, but the cooling potential of expanding 700bar gas back to atmosphere is significant. Compressed hydrogen is an explosion risk independent of oxidiser, so you have a double explosion risk, first the compression explosion then the chemical reaction in atmosphere of a spark (likely) is generated by the first. There are a bunch of other issues with it, but these are major ones.

Cryogenic hydrogen has it’s own I issues. I’m not as familiar with it.

Saying hydrogen isn’t difficult to work with is just your lack of experience. Difficult is just engineering challenges, but hydrogen has some unique issues that other options don’t.

If efficiency at point of use is faceted in, things get better for electric, bit not enough to bridge the divide.

Hydrogen is difficult to work with, massive compression or cryogenic temperatures. Metal embrittlement is a long term concern.

Windows, nothing I still dislike Microsoft products.

But seriously.
Peanut butter, good quality 100% peanut version changed my mind.

Bandit and Chilli Healer. Final answer.

I don’t get why materials for HVDC are so much higher than everything else. Towers and cables are relatively cheap, the substation hardware is not, but neither are pumping stations with all of the safety requirements.

Also why only 500kV when there are 1.2MV systems in the world. Not that it would make much difference since the bulk of the cost is down to materials.

I didn’t see the amortisation time in my quick skim through.

I know in NZ the compliance cost to get a pipeline through would kill any project that tried to do this.

Obviously leaks etc are ignored in this model, but they at a significant contributor to climate change.

The way to eliminate the risk is a lot more complex tracking wise but worth it for the risk reduction.

Effectively using spread focus tracking; multiple lower powered lasers provide the power to destroy the mosquito but no single laser has enough energy to damage your eye.

It would require extremely accurate positioning and pointing of the lasers and most likely two cameras for the tracking to get accurate distance to target. I thought of this years ago…but never really cared enough, I live in an area with no mosquito issues.
