We’ve been discussing it for 30 years.

Having people making the same stupid comment after 3 decades needs to be handled more critically

Let’s go back 40 years and listen to the warning:

We should show @blell some grace. Not everybody is born knowing everything. Today is the day they learned about climate change.

Grace is reserved for people with humility and a willingness to learn . Not self destructive suicidal death cult fools.

This again?

The test is optional. Feel free to skip it.

Tell 50 million people they’re likely to have Alzheimer’s then tell them where to donate towards a cure, or treatments to slow it by a decade.

Nobody is ever going to do that with this test, because the overwhelming majority of positive test results in a population-wide sample will be false, and the proposed diagnosis is devastating. This is a test for people who already have symptomatic dementia that helps confirm the diagnosis.

Well this test isn't for whether you will get Alzheimer's, so that disqualifies it before we even consider the accuracy.

But apparently your odds go above 30% if you live long enough, so if you could test for being in that cohort I think that result would be too common to actually be devastating.

> Tell 50 million people they’re likely to have Alzheimer’s then tell them where to donate towards a cure, or treatments to slow it by a decade.

Pharmaceutical companies have spent something like $50 billion on developing Alzheimer's drugs with, well, the most furtive of straw-grasping to show for it. It's probably the most expensive single disease target (especially as things like cancer are families of diseases)... the failure to have good results isn't for lack of money, and merely throwing more money at it is unlikely to actually make progress towards meaningful treatments.

It just seems really obvious to me that it's not one disease. One problem with the research is that there is SO much money. It's corrupting. There's a whole thing about the plaque cartel and if you aren't testing around a possibly flawed concept the availability of funds is much lower.

I just feel the thinking is off, it's like we are trying to treat cuts by removing scabs and scar tissue. We really need deep investigation on the sources, which I feel in many cases are industrial chemicals and how some people's body / immune system respond to them.

One of the most compelling studies I saw was how distance from a Golf Course predicted neurodegenerative diseases, based on their use of certain pesticides.

So, you’re saying it’s an unsolvable problem?

Someone always says “merely throwing money at the problem…”

What time period was the money spent? The last 25 years?

The United States spends $1 trillion a year in debt interest. $50 billion is nothing

I wonder if after services like 23andMe became popular and millions of people found out they have the Alzheimer genes, did donations towards brain research rise?

Gosh, it seems like only yesterday we were being shamed for flying to take a vacation.

Now, along with reintroducing measles, we’re preparing to really crank up our greenhouse emissions

People also don’t think he’s one of the greatest physicists ever.

As he said, he was just an ordinary person who worked very hard.

Everyone thinks they are ordinary. If you have 160 IQ that just feels ordinary. You can only really measure ordinary in terms of achievement.

The 100 IQ person that works that hard doesn't invent that much physics. They might get rich, change the world etc.

Well, the Nobel committee certainly seemed to disagree with you.

I guess you didn’t watch the video so you don’t understand the point I’m trying to address.

At any rate, this garbage doesn’t belong on HN.

Can you elaborate on that point? I didn't downvote you, but I'm also not going to watch a 3-hour #metoo video about a guy from my grandfather's era in order to understand what you mean.

What's next... is she going to tell me that Newton was a real asshole? Noooooo, say it isn't so.

It’s discussed in the first few minutes. That’s basically all I watched. One of the first points she tries to make is that people claim that Feynman is one of the top physicists of all time, comparable to Einstein and Newton. She tries to set us straight.

Anyway, I’m a big Feynman fan. My Discord handle is feynman1918.

“The reversal targets the 2009 “endangerment finding,” which concluded that six greenhouse gases pose a threat to public health and welfare. The finding provided the legal underpinning for the Environmental Protection Agency’s climate rules, which limited emissions from power plants and tightened fuel-economy standards for vehicles under the Clean Air Act.”

What does it mean “if it works “?

What happened to cheap home solar with batteries?

Installation costs dominate the price. I check every few years, and while the hardware is down to about $5k for me, cost for installation remained $45k-$50k. Which is where it’s been for years. Makes diy very attractive though.

This is bananas. Ten years ago I paid £5.5k for a whole 3.9kW installation, which has now more than paid for itself. I can see why everyone in the US is saying "get a trade job", you can rip off householders to a massive extent.

That cost makes absolutely no sense. It takes one single day for a couple of people to install solar and batteries on a residential house.

Baumol's Cost Disease at work, I guess.

It's a third or fourth of the price in Australia with equivalent labor costs.

It's mostly unnecessary red tape and a broken market that cause the differences.

Australian labor costs are significantly lower than the US, as are labor costs in most countries. Americans are paid pretty well.

Solar installer costs are broadly comparable as Australians are better qualified and even if they weren't comparable the fraction of the cost isn't enough to explain the total difference.

There's various studies comparing the two countries, Tesla did one and found various technical approach changes and permitting reforms. It suggests labor is 7% of the cost in the US. Soft costs around acquisition, sales and marketing can be 18%.

What kind of power we're talking about here? I was quoted €10600 (around half of which will be government-subsidized) for 8 kWp worth of panels + 10.24 kWh battery storage, including project documentation (for subsidies), labor, and materials.

50k? I could fly there, stay somewhere nice, buy a decent truck, put the solar PV on your roof, and make it home with 20k in my pocket to upgrade my solar power with and a truck.

That explains why many tradesman here are always driving new trucks.

How big is that system? Without incentives mine was half that for 8kw.

How hard is it to DIY?

The installation is straightforward, but the problem comes when you want to connect to the grid, because you have to get it approved by the utility. I'm sure getting a DYI installation approved by the utility is _possible_, but I wouldn't count on it. And, you may not know that you got disapproved until you've made the investment and are sort of screwed.

What I did was install solar with batteries and inverters that have the ability to never export power to the utility. That way I didn't have to tell them or seek their approval.

You don’t really make that much electricity in the winter when you need the heat

I picked a random spot in New York state. It looks like the solar generation in January is about 68% of July. As solar keeps getting cheaper, one option is to just install more solar.

Don't get me wrong, there are still issues here, like snow or back-to-back-to-back cloudy days. But the rate of a price change for solar has been pretty dramatic.

That's my challenge in Colorado.

I installed a modest solar system (5kwh) in 2024 and was incredibly happy with the results. On any given 24 hour period it'd offset 40% of my electricity consumption (EV, hot tub being the big loads).

Last year I installed a cold climate heat pump. I'm incredibly happy with the switch from gas as my primary heat source. The solar now only covers ~15-20% of my consumption in winter.

So my solution this year will be to add more solar. In the two years since I installed mine prices have halved. I'm fortunate enough to be able to do a DIY install, properly permitted and inspected, for about $350/400w panel once you factor in inverters, mounts, etc.

It's an amazing time for affordable energy.

Where are the emissions generated? Far away from the population of millions.

And much more cleanly/efficiently than a small gasoline-powered generator, regardless of the energy source.

Coal-powered steam turbine is not that more efficient than a portable gas generator so considering coal is more carbon-intensive it's actually about the same or even worse in terms of emissions if you consider coal burning also produces mercury. Now nat gas-powered CCGT - different story. Good news is NYC is mostly powered by the latter and there's zero coal.

EVs are already cheaper to produce. That’s why the US has a 100% tariff on Chinese EVs.

I’m going to Miami next week. Time for my first WayMo ride.

Weirdly (well not for me it's a charter metal festival cruise) I am too and interested in doing the same. Typically we use Uber and it's been a not great experience.
