This lacks a topic and a list of any unsuccessful choices of letters. Makes it too hard compared to earlier puzzles.

The great Roman dictator had his name immortalised. Caesar became Kaiser, Czar, Tsar, Shah and a salad.

To be fair, we were all wearing tinted safety glasses on that ute. Three of us in the front and five or six in the back (I took the photo).

They pulled it out. I don't know whether it was fixed, I guess so because they had extensive workshops and lots of apprentices. We had to use big International utes after that. Here's a pic on the way to a job.

Its just another dating service.

I was working on a mine that used Mini Mokes for scouting around the lease. We had some empty bitumen lined overflow dams that were near the mill, and we used to take a shortcut through the dams. One day there was an overflow and the dam had a metre or so of water in it - my mate drove the Moke in without looking and it almost disappeared. I reckon just the windscreen was sticking out.

There really aren't that many new sources of copper. The ones I have reported on all seem to have problems. Some have massive environmental impacts. Others, worldwide, have first nations objectors. There is a difference between a natural deposit in the ground, however massive, and a resource that can become an ore reserve. Trump seems to be finally overruling the objections to Resolution Copper in Arizona, but it will be the deepest large underground mine in the world and I expect there will be massive problems developing and operating it. It will be a Block Cave 2000 metres deep. Recent block caves by Rio Tinto have not gone well.

"Your average EV has six times more mineral content than a petrol- or diesel-powered vehicle. All those metals need to be dug, scraped, blasted, or leached out of the earth. There is massive demand for batteries as countries eye up ambitious zero-emissions targets. But what's the cost?" This is the intro from an article in Business Insider. See The true cost of the global resource race to make electric car batteries While I expect most of the people here will leap to discredit MSN or the authors, please do some research first. Let me give you the true situation using copper as an example. This is based on my own data and calculations, so don't ask me for a reference. Minera Escondida operates two open pit copper mines in the Atacama Desert, 170 km southeast of Antofagasta in northern Chile. It is currently the highest producing copper mine in the world. I have been there. Construction of the mine started in 1988, which including the stripping of over 180 million tonnes of waste to get to the orebody. If we amortise that over the last 37 years, it is about 5 million tonnes per year. They mine about 340 million tonnes of rock (ore and waste) per year, so total mining including the pre-strip is 345 million tonnes. From this they produce 1.4 million tonnes of copper. So, they mine 246 tonnes of rock to get one tonne of copper. A Tesla model S contains 82 kg of copper, so it requires mining 20 tonnes of rock. And this is the highest producing mine, others are less efficient. Goldman Sachs are forecasting 73 million EV sales globally in 2040. This would require mining 1.46 billion tonnes of rock if all mining was as efficient as Escondida. And of course there are many other minerals involved. Nickel is currently in the news with Indonesia stripping vast areas of forest to strip-mine lateritic nickel. The madness has to stop before we destroy our planet.

Onetrack I was running a mine contracting business in the late 1980s (JARA mine construction) and we had similar problems. We dropped the contracting and went consulting. Over the next 30 years there were times I tried to borrow from banks but they wanted personal guarantees. Then when our business was booming they tried to lend us money but we didn’t need it.

One MW is a flow rate of power, 100 KWh is the stored quantity. The faster you want to fill it the more flow you need.

Our forecast is one degree from now 8 pm until tomorrow morning.

Battery size / charging power = charge time A Tesla has a 100kWh battery 5 minutes is 5/60 hours. 100/x = 5/60 6000/x=5 x=600/5 x=1200 kW = 1.2 MW But we are not starting from dead empty, so say 1 MW.

The extremely fast charges now being talked about, in 5 minutes, require 1 MW per vehicle. So, a ten-car station would require 10 MW. This is simply impossible. The half hour charge is probably the best we will see.

When a group of Spanish journalists embarked on a 2,500-kilometer journey across Europe, their mission seemed clear: test the viability of electric cars on long-distance trips. But after their trek from Berlin to Madrid, the team returned with an unexpected conclusion. One major factor they couldn’t ignore: the time spent waiting for the vehicles to recharge was often far longer than the time it would take to fill up a diesel car at a fuel station. When the journey came to an end, the team sat down to crunch the numbers. According to data from the European Union’s official fuel price reports, the costs associated with recharging the Teslas were significantly higher than refueling a diesel vehicle. Over the course of 2,500 kilometers, recharging the electric vehicles cost them €53.62 more than if they had fueled a comparable diesel car. This cost discrepancy grew even more when comparing the electric vehicles to a gasoline car, with the electric vehicles’ total fuel cost exceeding the gasoline vehicle’s by €136.61. The study underscored a stark reality for electric car enthusiasts: while electric vehicles are often advertised as more affordable to fuel, long-distance trips could incur unexpected costs—particularly if fast-charging options like Tesla’s Superchargers are used. After Driving 2,500 Kilometers in Electric Car, they Reached an Irrefutable Conclusion: “Diesel” Is Still King on the Road

The July 2015 deal was aimed at making it harder for Iran to make a nuclear bomb. At the time, it was believed Iran might be two to three months away from getting a nuclear bomb. But if Iran abided by restrictions imposed by the deal, it would take at least 12 months to build a weapon. In exchange for curbing its nuclear program, Iran got access to tens of billions of dollars in assets (estimates are as high as $150 billion, but the exact amount is not known). But the vast majority of those assets were Iran’s own money, assets frozen as a result of sanctions imposed on Iran by the United States and other countries. Clinton has said that her work as secretary of state in putting together sanctions against Iran helped usher Iran to the negotiating table. But Clinton was referring to work she did in 2009 and 2010. And she left the secretary position in February 2013. That means Clinton was gone for 2.5 years before the nuclear deal was struck. In other words, the heavy lifting was done under John Kerry, although Clinton endorsed it. And President Barack Obama had to sign off on the deal, so it belongs to him more than any secretary of state.

I know virtually nothing about military weapons. But I do know about blasting rock and have done my fair share of it when I was young. It is hard to understand how those bunker buster bombs could damage a deep underground facility. Quite a few times I have been a couple of hundred metres to the side from a blast a couple of tonnes of explosive at a depth of around 1000 metres below the surface. I put my fingers in my ears, and stood in a side tunnel, but was never in danger of being blown up. Nothing was damaged in the mine, other than the rock being broken where it was intended. This happens all the time in large mines with large stope blasts. So if the bombs did not penetrate the facility, the shock wave probably didn't destabilise the tunnels and galleries very much. If they had centrifuges or delicate machinery, then it could certainly have been wrecked. My point is that the tunnels and galleries can probably very easily be reinstated and are not actually destroyed.

No, I am happy to believe whatever reinforces my political inclinations. Like just about everybody who posts here.

He said he would decide within two weeks. Exactly what happened. A bit deceptive, exactly as intended.
