Why Alice Friedmann is wrong

Just 16 months ago Alice Friedemann asked:-

Diesel is finite. Trucks are the bedrock of civilization. So where are the battery electric trucks?

The answer is Tesla!
Tesla electric trucks will be not only be safer, smarter, faster, and more reliable than diesel trucks, they’ll work out 20% cheaper! They’ll have emergency self driving capabilities, and with bullet-proof glass enjoy less time off road. (In today’s best diesel trucks, mere windshield damage is at least an annual cause of late delivery of goods). They have a 500 mile range and recharge in 30 minutes while they unload.
Oh, and for fun it was carrying the new 2020 Tesla roaster as a “But wait there’s more!” moment. It will be the “fastest production car, period!” and have a 1000km range. That’s Sydney to Melbourne in one charge.

Please, no third Blade Runner movie!

No third movie! Not if the point is “tidying everything up in a nice bow”, as Collider said in the video below. The 2 Blade Runner movies are the Socratic method at its best: asking the ultimate questions about the value of human life, what is sentience, who are we, and how are we to live? A third movie would reduce these classics to a mere Hollywood ‘story’, something synthetic like Joi, a product. But as they are right now, they are something more. Some have asked what all the hype is about the original Blade Runner movie given the plot is quite thin and it takes a long time to unfold. But these movies are positioned and sound-scaped to make us feel something beyond the plot. The mood is the meaning. They are high art. I fear answering all our questions would shirt-circuit the whole point of the two Blade Runner movies and ‘tidy them up’ in a manner that was too domesticated for the raw emotion intended in these masterpieces.

Forget Left V Right, meet Up V Down-wing!

Wow, I’m having flashbacks to my peak-oiler days. “Left” and “Right-wing” versus “Up” and “Down-wing”. I used to have time to read and discuss this stuff. Those were the days! This great article from Slate discusses how elements of both left and right fall into regressive localism “Down-wing” of the modern world, and how elements of both left and right should try and align with a more technologically optimistic “Up-wing” view that celebrates high tech that can both eradicate poverty and protect ecologies. It’s time to move UpWing, and save both people and the planet.

SpaceX airlines?

The EveryDay Astronaut has a good breakdown of the much longer, rambling Elon Musk presentation. It’s 11 minutes compared to Musk’s 40 minute presentation.
In a nutshell, Space X couldn’t fund last year’s plans for a truly gigantic 12m diameter giant ITS (Interplanetary Transport System), because it would have required them to front the cash for a whole new rocketfactory first!
Instead, Elon has decided to scale back the ITS to “just” a 9m diameter ITS — which will still be the biggest rocket the human race has ever built — and build it in the existing factory. It’s so big, and so reusable, that it will be far cheaper than their existing fleet of much smaller rockets. It’s going to become their main workhorse in the satellite, ISS, and moon market, and eventually will replace all their existing rockets.
It will be bigger and cheaper than anything in the rocket market today, and let them cut into the airline industry! This rocket will get you most places in 30 minutes (and anywhere on earth to anywhere in an hour). If they can do that and still turn a profit, then this is the system that will eventually get us to Mars.
Who knows? If in a decade or so SpaceX has enough money, maybe they’ll build a new factory for the 12m diameter ITS, or something even bigger? But for now, I’m excited by the fact that the ITS looks like a practical workhorse for SpaceX to make us an interplanetary species, and one of the biggest questions going is what will they name the thing? I like cool names like the “Super-Dragon” or any other bird of prey name, but Spacey McSpaceface has also been suggested. 😉

Nuclear power PREPARES for climate change!

How many solar farms and wind turbines did cyclone Harvey kill? But the nukes? They’re in concrete hardened bunkers. They’re fine. Nuclear power doesn’t just mitigate climate change, it *prepares* for what we’re already committed to! As Forbes said:


 

Hurricane Harvey made land fall in Texas this week and the flooding was historic. What is shaping up to be the most costly natural disaster in American history, the storm has left refineries shut down, interrupted wind and solar generation, caused a constant worry about gas explosions, and caused a chain of events that led to explosions and fires at the Arkema chemical plant that is only the beginning.

Over a fifth of the country’s oil production has been shuttered. Natural gas futures hit a 2-year high as did gasoline prices at the pump.

But the Texas nuclear power plants have been running smoothly.

The two nuclear reactors at the South Texas Project plant near Houston were operating at full capacity despite wind gusts that peaked at 130 mph as the Hurricane made landfall. The plant implemented its severe weather protocols as planned and completed hurricane preparations ahead of Category 4 Hurricane Harvey striking the Texas Gulf Coast on August 25th.

Anyone who knows anything about nuclear was not surprised. Nuclear is the only energy source immune to all extreme weather events – by design.

This nuclear plant has steel-reinforced concrete containment with 4-foot (1.2 meter) thick walls. The buildings housing the two reactors, vital equipment and used fuel have steel-reinforced concrete walls up to 7 feet (2.1 meters) thick, which are built to withstand any category hurricane or tornadoe. It can even withstand a plane flying directly into it.

The plant is located 10 miles (16 kilometers) inland and at an elevation of 29 feet (8.8 meters) above sea-level. The facility is designed with watertight buildings and doors, with all buildings housing safety-related equipment being flood-proof to an elevation of at least 41 feet (12.5 meters).

‘We’ve got significant rain but flooding has not been an issue here,’ plant spokesman Buddy Eller said in a phone call about the reactors.

That the nuclear plant is just fine seemed to irk anti-nuclear groups who don’t want to see nuclear ever performing well, even if it helps the storm-wracked people of south Texas when other power sources are failing.

Three watchdog groups, the Sustainable Energy & Economic Development coalition (SEED), the South Texas Association for Responsible Energy and Beyond Nuclear recklessly urged politicians, the owners, and regulators to shut down the plant because of Harvey, even if it hurt residents, emergency workers and hospitals who desperately need that power.

But the regulators and the State would have none of that nonsense, understanding that these groups just peddle fear. The reactors provide 2,700 MW of power to 2,000,000 customers in the area.

U.S. Nuclear Regulatory Commission (NRC) staff are at the plant, constantly assessing the situation and safety aspects. ‘The South Texas Project reactors have been operating safely throughout Harvey and continue to do so,’ NRC spokesman Scott Burnell said. The reactors can be shut down quickly if something develops, but that’s not expected to be necessary.

Two-hundred and fifty storm crew workers, along with regulators, were running the plant and were set up with sleeping arrangements, food and water to weather the storm no matter how long it took. None of them were afraid, knowing how safe the reactors are.

No other industry was as prepared.

According to the online news source North American Wind Power, one large wind installation in the path of the storm sent all 39 workers home as the hurricane closed in, but operated remotely until the wind hit 55 mph. It then shut down automatically like all farms when wind speeds exceed their design limits. Most wind farms have not sustained much damage, but getting them back to capacity will be difficult.

The Nuclear Regulatory Commission also said Harvey does not pose a threat to the Waterford Nuclear Power Plant in New Orleans and the River Bend Plant near Baton Rouge.

We’ve seen this before. Last summer, a heat wave cooked Americawith extreme temperatures, affecting most energy production as well as causing fires and water shortages, sucking electricity like crazy to power the cooling necessary to avoid discomfort and even death. According to the National Weather Service, 122 million Americans were under heat alerts.

Fortunately, nuclear power didn’t mind, scoring record capacity factors of 96% and up, with no increase in price. Other energy sources did not fare so well and some gas plants gouged consumers just because they could.

In 2014, a Polar Vortex shut down natural gas and coal plants, and stopped wind turbines and solar generation. But nuclear performed wonderfully and provided more power to the hard-hit northeast than any other source.

Whether it’s hurricanes, floods, earthquakes, heat waves or severe cold, nuclear performs more reliably than anything else. There’s no better reason to retain our nuclear fleet, and even expand it, to give us a diverse energy mix that can handle any natural disaster that can occur.

Organic looking robots work smoother

As a layperson Geek watching the development of robots over the years, what fascinates me is the way engineering requirements — not aesthetics — are driving the evolution of some robots to *look* more organic.
