And yet home solar panels keep working!

Solar panels dont wear three layers of clothing and a beanie to go outside.

That is a matter for a person, not a demonstration of new strange physics during winter!

You can sit inside in the warm in a northerly aspect and get 30 ~ 60 minutes of midday sun, it still works through glass.

Its funny, how wrong we can be, and right we can be all at the same time.

2)    UVB radiation:  Your skin requires UVB radiation to produce vitamin D.  Since glass blocks UVB – this means you need to be outdoors in the sun.  As we discussed in our section on irradiance, UVB is produced by the sun; and in our section on insolation, the amount of the sun's radiation varies with latitude, altitude  (e.g. in Denver you need 20% less time in the sun because of the altitude), weather conditions, time of day, time of year, etc.

While it is generally true that you can produce solar energy – as long as there is visible sunlight, the research on producing vitamin D from the sun seems to suggest that there is a threshold level of UVB your skin requires in order to produce Vitamin D. 

In other words – depending on where you live - the number of days and hours where there is sufficient UVB radiation your sun can use to produce Vitamin D will vary.  So while it might take you 15 minutes in the peak (10:00 AM  to 2:00 PM) time in the summer to produce the vitamin D you need – it could take much longer than that in the spring and fall  (substantially more if the weather is still chilly and you are wearing more clothing), and may not be possible at all in the winter.

@ Thry

I spent much of my early life in a cold climate devoid of too much sunshine for months at a time. It proved to be  real problem for the darker skinned people who suffered from Rickets (caused by Vit D deficiency) unless they took a supplement.

It's often propagated by the health industry that you need supplements, unless you have some medical condition that affects your production of vitamin-D you do not. Females are about 10x more likely than men to need supplements as they age due to biological concerns.

UV radiation is a continuous spectrum, that is divided in UVA, UVB and UVC to simplify discussions about it's effects on biology.

In reality all UV is attenuated by glass and other transparent surfaces, but it's not a cut-off filter effect. It is a curve like the graph below with UVB between 285 and 315nm, UVB is only a small percentage of solar UV radiation.

Note that graph is based on 10mm glass, most homes or buildings only have 3mm or 4mm glass!



Car windscreens and, greenhouse glass some of which contain reflective films can greatly alter the effect. But all it does is change how much time you need to spend in the sunlit window, being behind simple glass does not stop it the production of vitamin D it just slows the rate of production!

Plus, be careful reading websites, the data might be based on and targeted for people living in the Arctic circle, but then they are pale white in general for a reason, it is not an accident many are translucent blond!

Frankston hospital in real trouble with 700 staff being tested for Covid and patients being transferred out, fair chance to close IMO as they dont have the staff left to handle the workload unless they get other hospital or interstate help.
Three wards closed a week a go but that never made the news and a lot of the staff came down sick but again they didnt want
that making the news either .....staff are being tested even if not sick.

I heard they moved a bunch of SARS-CoV-2 positive patients out of northern suburbs aged care into Frankston Hospital a few weeks back, I bet they regret that now!

FWIW, I also heard a rumor they did the same over at Peninsula Private Hospital, that would be the two major hospitals in the area put at risk by the transfer of patients out of the northern suburbs!

There are a bunch of Emergency Services workers down that way who are ropeable about how it was handled!

[capcom]

I'm not sure what's worse.  What's revealed or what's not being told.  The secrecy is despicable, either from this government or the idiot media (or both) in not pursuing the truth.  One thing is certain ... aged care will change enormously from this point forward

Its a badly managed hospital at the best of times and like Sunshine hospital in the West its under resourced and under pressure just with day to day business, both areas need another Public Hospital built and staffed properly.

 Maybe that is the political motivation behind the current series of events, the State will put it on the Feds as public health is primarily a Fed concern?
