One question I had but was not answered by the FAQ is whether the London Mainnet updates will require updates to Beacon / validator implementations. Apologies if the answer is obvious to everyone else, but is is not obvious to me.

An important aspect of this is that it is located in Singapore. Singapore is a heavily regulated sandbox in many, many areas. And it is small. For example, there is only a single companies registry and only a single tax authority. And Singapore has a history of mandating big changes. And a lot of effort sunk into presenting itself as cutting edge in terms of government services and management of its population. I'd suggest that it may be possible for Legalese to try some things in Singapore, perhaps in concert with one of the government authorities, that could be an interesting demonstrator.

(Disclosure: One of the founders is a good friend, and I am wishing them success.)

Are you saying that trading on market sentiment is an invalid trading strategy?

I am with you brother. If there is an argument for bitcoin, this is it. Large banks that impose their own priorities over that of their customers.

I got a little from the Bitcoin Faucet too. The wallet is long since lost...let alone the password.

"Why should I take a 125% hit when I'm providing a convenience for the patient by doing all their scans on the same day?"

You don't see what is wrong here? If your mechanic told you he wanted you to come to the shop 3 times instead of one for his convenience, you would find another mechanic.

I'm from the US and I've lived in Singapore and the UAE for many years. And I've had to deal with the US system from time to time as well. Medical services cost a fraction in Asia and the Middle East compared to the US and the paperwork is much simpler. And most of the doctors are educated in Europe. And lately I've seen more US doctors moving abroad simply out of frustration.

One time I was in West Virginia with my family and I had trouble catching my breath so we went to the ER. 1.5 hours of waiting, literally a 5 minute visit from the ER doctor and a 3600 USD bill. No treatment. No meds. Later I had to negotiate with the hospital over the bill. Eventually they told me that the insurance reimbursement rate for my vist would have been 600 bucks, but because I had no insurance, I was expected to pay 3600. I eventually got it down to 2200 after much angst and effort. Sick people don't need this aggro. Nor do they need the pain and discomfort for visiting the medical facility 3 times instead of 1 because of the vagaries of the US insurance/hospital billing system.

The US system is broken.

This sounds both interesting and audacious. I'm nearing retirement and considering various options for what to do next. Could you explain how you earn $$ from 'social presence'? I'm a personable guy, but I don't know that I could convince anyone to give me money just for showing up to something.

REALLY bad article. Don't waste your time.

I was just in Singapore for the past few days, after living there for several years. It really is awful this year.

The haze did make the laser show from the top of the Marina Sands really spectacular. ;-)

It is a fantastic automobile and a great video from Jay Leno, whom we all owe a debt of gratitude for preserving our technological legacy, similarly to Bill Harrah from a generation earlier.

Imagine what a Doble could be with a few processors handling all the complexity....

Well I never took the PE exam, and it is a couple of decades since my undergrad and graduate engineering degrees that included a couple of courses in thermo, so things are a little rusty, but prodded by a few of these posts I've just dusted off the math and made a go of it. BEST case, requires an 8 oz zinc-air battery. And they are going to sell that, and the device itself for $3..?!

Part of my reaction is that I am a patent attorney, and every patent attorney gets 'inventions' that come through the door from well-meaning but essentially clueless people. After a while you get to develop a bullsh*t detector. This one just rang my gong. I suffer from sleep apnea and I know what a real thing it is, and the idea of these guys just walking away with $$ from desperate people, just, again, rang my gong.

I will say that it has been fun seeing these posts--thank you!

Well now I guess I have to do the math:

W = P(b)V(b) ln(P(a)/P(b))

(https://en.wikipedia.org/wiki/Compressed_air_energy_storage)

CPAP requires roughly 10 cm of water pressure = 0.01 Bar Sea level atmospheric pressure is roughly 1 bar So the device has to pressurize to 1.01 Bar Now I’ve looked it up, and a typical CPAP machine moves 20 to 60 liters per minute Let’s say 30 liters per minute = 1800 liters per hour

W = (1.007)(1.8)ln(1/1.007) = (1.81)*(-00698) = 0.0127 MJ = 3.53 Watt Hour

So assuming perfect efficiency you would still need 28.64 watt hours of battery, just to do the compression.

470 Wh/kg for Zinc-air battery implies this device requires a 60gm battery (2 oz to those of us of a certain age)

I looked up CPU fan efficiency (what they say they derived it from) and PEAK fan efficiency only approaches 25%

So, you’d really need an 8 oz battery hanging from your nose to make this work, not counting what you need to run the electronics, etc.
