A Message from Alaskans (to Texas) on Wind Power

Spacedog79 says...

The whole industry in the US is being hamstrung but obstructionist greens, lack of access to cheap financing and dithering politicians.

Asia are building reactors on time and on budget, the US and EU need to play catch up especially as China and Russia are developing soft power from exports.

I'm all for nuclear, but what's the reality of that happening in the states anytime soon or at all? Are there plants being built right now or planned to be built?

A Message from Alaskans (to Texas) on Wind Power

Spacedog79 says...

Indeed, amazingly the wind power in Texas actually met expectations of the power it would provide in the cold snap.

The trouble is wind is so undependable they only counted on there being about 10% of capacity available. Wind gets absolved of blame by having almost no expectation that it will be available in the first place.

I say screw wind, build nuclear reactors instead and get the job done properly.

The bullshit lie Texan politicians sold was that wind turbines don't work in the cold. They do.

In Texas, the good old fossil fuel plants failed before the wind turbines and for longer....so couldn't pick up the slack. Had the turbines been retrofitted to operate in cold, a simple fix strongly suggested the last time their grid failed from cold, they could have taken up the slack from the failed fossil fuel plants and kept Texas out of the dark.

Why are we picking this guy over Sanders?

Spacedog79 says...

Sanders wants to ban nuclear power which would be a disaster for the planet, while Biden supports next gen reactors which are the future and will one day power everything. I like Sanders but is is a stupid and ideologically driven policy.

Star Wars: The Rise of Skywalker | Final Trailer

Digitalfiend says...

I still have a hard time getting into these new movies with Rey as the protagonist. The first movie started off promising but the Last Jedi really killed it for me. Rey will probably end up choke-slamming the Emperor back down the nearest reactor shaft without breaking a sweat, so, I'm just going to see it for the space battles...

Could Earth's Heat Solve Our Energy Problems?

newtboy says...

The 1mSv per year is the max the employees at the dump/recycling plant can be exposed to, so leeching more than that into public water systems seems impossible unless I'm missing something. This comes mainly from solid scale deposits removed from the closed loop systems.
Average employees in German plants seemed to get around 3 mSv/yr on their table.

At Fukushima, According to TEPCO records, the average workers’ effective dose over the first 19 months after the accident was about 12 mSv. About 35% of the workforce received total doses of more than 10 mSv over that period, while 0.7% of the workforce received doses of more than 100 mSv.
The 10mSv was the estimated average exposure for those who evacuated immediately, not the area. Because iodine 131 has a half life of 8 days, the local exposure levels dropped rapidly, but because caesium-137 has a half life of 30 years, contaminated areas will be "hot" for quite a while, and are still off limits as I understand it.

Sort of...., most of the area surrounding Chernobyl is just above background levels after major decontamination including removal of all soil, but many areas closer to the plant are still being measured at well above safe levels to this day, and unapproachable, while others may be visited only with monitoring equipment, dose meters, and only for short times. It's not back to background levels everywhere, with measurements up to 336uSv/hr recorded in enclosed areas and abandoned recovery equipment (the claw used to dig at the reactor for instance)....no where near that low at the plant itself. Places like the nearby cemetery which couldn't have the contamination removed still measure higher than maximum occupational limits for adults working with radioactive material. The radiation levels in the worst-hit areas of the reactor building, including the control room, have been estimated at 300Sv/hr, (300,000mSv/hr) providing a fatal dose in just over a minute.

Don't get me wrong, I support nuclear power. I just don't believe in pretending it's "safe". That's how Chernobyl happened....overconfidence and irresponsibility. If we consider it unacceptably disastrous if it goes wrong, we might design plants that can't go wrong...The tech exists.

You'd be surprised.

Geothermal try to keep public exposure to less than 1 mSv per year.

Living near a Nuclear Power station will get you about 0.00009 mSv/year.

Living in Fukushima will get you about 10 mSv in a lifetime, with life expectancy there at about 84 years that is 0.177 mSv/year.

https://www.who.int/ionizing_radiation/a_e/fukushima/faqs-fukushima/en/

Even Chernobyl is almost entirely background radiation now. Radiation is all scaremongering and misinformation these days, so people freak out about it but it really isn't that dangerous. It takes about 100 mSv a year to have even the slightest statistically detectable health effect and far more than that to actually kill someone.

David Attenborough on how to save the planet

Spacedog79 says...

Nuclear energy is the only way we can do it, we can run the planet forever and do things cleanly and more densely to leave more of our planet for wildlife.

The trouble is almost everything we hold as common wisdom about it is completely wrong, using breeder reactors have enough uranium to run the planet forever leaving almost no waste and removing the possibility of big accidents which actually aren't as harmful as commonly believed anyway.

We have thorium too, and many designs of each that can do the job. In fact we have a wealth of of options, but also a decades old and highly effective PR campaign from the fossil fuel industry to convince us otherwise.

We Believe: The Best Men Can Be - Gillette Ad

BSR says...

Funny thing about anger. It generates energy. Pure unadulterated energy. Much like a nuclear reactor. It can be somewhat of a gift. Anyone can do anything they desire with that energy. What a person chooses to do with that power can strengthen them and others or destroy them and others.

Don't let Trump destroy you.

newtboy said:

Not by intent, but as the model for America's youth of the best known and most successful person that constantly and clearly exemplifies every bad behavior mentioned to a ridiculous extreme, publicly and proudly, and worse is rewarded for it by his base, it is somewhat about him, intentionally or not.

Trump, our "leader", is following that outdated map and dragging the country along the path. It's hard to get people to change course when the leader keeps driving them farther down the wrong trail.

How Neutrons Changed Everything

Spacedog79 says...

Fair point. I barely consider reactors that need control rods as a legitimate design, there are much better ways to build a reactor that doesn't need to depend on such things for safety. Basic design using a molten salt core should be more than enough, and in any case none of them are anywhere near the chain reaction that would be in a nuclear bomb.

Jinx said:

So does inserting a control rod actually speed up the reaction?

Armadillo Cargo Bike With Hydrogen Fuel Cell, 300 km range

AeroMechanical says...

In terms of exploding or burning, probably not nearly as dangerous as gasoline. The biggest problem with it is that, since the molecules are so tiny, it's very hard to store and transport without it leaking away. Also, the standard procedure for getting hydrogen from water (electrolysis) requires considerably more energy than you get out of the hydrogen, so that's a problem. Still all that aside, if you use power from a nuclear reactor to crack the water to make the hydrogen, you have a nearly unlimited supply of a portable, energy-dense, very clean fuel. Researching and refining its use as a fuel is a Good Thing.

Sagemind said:

I thought we learned our lesson with Hydrogen?

Does any know what the dangers are ,when compared with regular gasoline? (or other fuels).

( I admit I'm uninformed and judge all Hydrogen vehicles by the fate of the Hindenburg.)
