Yes, it is time to draw a line under Covid19 and move on.
Lets face it if our queen can catch Omicron variant and just carry on working as usual then so can everyone.  The quicker we stop testing and assume everyone has already had covid and survived the better.  Only doctors in hospitals should be allowed to authorize a Covid test and certainly no death should be recorded as a Covid death unless the coroner is absolutely sure that it was the only reason for death.

It appears that the UK is about to do a U turn on their insistence that all NHS staff must be vaccinated due to staff shortages.
Boris needs to go further and revise the policy that recommends that NHS staff and critical workers need to self isolate if they have been in contact with a person with a positive Omicron Covid result as that is like telling the tide to stop coming in or banning the common cold..
 Only new delta variant patients should be counted as Covid19 cases and probably not people over 80 that die within 28 days who have other more obvious reasons for dying.

I am afraid we will not have any choice in the matter of who will survive as the omicron variant will now rapidly affect everyone.  Everyone will test positive at some stage although 99-9% will not even know.
Anyway, health and critical service workers cannot be allowed to isolate when they meet someone who is positive, as they are required to continue looking after hospital patients who will otherwise die of starvation.

It is a numbers game really.  Spanish flu appears to have killed 0.3% Aussies or 3,000 per million which is still extremely high as Covid is only killing 107 per million due to better vaccines.  Looking at world stats     https://www.worldometers.info/coronavirus/   the world population is still increasing at over 1% per year which results in more CO2 in the air and could be linked to climate change.  Maybe a "let it rip" approach may be better for the planet in the long run.

Australia has a real problem with Omicron as it spreads so fast that another tactic other than tract and trace must be used to avoid high R rates.
Well, if you are feeling flu'y then go to bed immediately and inform nearest and dearest of your plight. Do not go to a test centre as you may then be infecting around 6 or 7 other people or if you test negative you will yourself probably have caught it from them.
Its a numbers game so if everyone in the world is to catch Omicron this year then Australia with 25 million people will have 25,000,000/365 =68,000 per day.    Well, luckily most people have been vaccinated and will not even know they have the Omicron variant; so what then is the point of testing if it will cause them to isolate causing unnecessarily disruption?.

Yes, the research appears to be a joint effort with pharma and universities sharing the costs of running the laboratory experiments.   So if the costs are shared then so also should be the patent rights.  Enough of pharma financial director and market manager running around in Ferrari's and overcharging the public for a third injection and unnecessary additional testings that only confuse everyone into believing they need an extra jab.
 To most double vaccinated people Omicron is just like a common cold and disappears after a week.

COVID-19 / Re: COVID: what does the future will look like?

« on: 30/12/2021 00:46:16 »

If you are correct in guessing that it covid could mutate into something similar to a common cold then we should immediately start to get back to normal.
To stop media hype we should not issue information on test results; in fact we should tell people to self isolate if they have a cold, loose their taste or have a temperature which could be flu.  Only doctors should be allowed to authorize a test.

Alan,   
What needs to be addressed is the requirement to self isolate if you have been near to an infectious person.  This is causing many sportsmen in particular to miss fixtures unnecessarily.  If a covid test then shows them clear then let them play and leave the team medics to keep an eye on them.

To me, everyone is infectious anyway and is carrying the virus but because they have been vaccinated do not develop the flu. Isolation for me is totally unnecessary unless you have tested positive to covid in which case it should be mandatory to stay at home and is common sense anyway.
Medical staff should be the very first to receive any vaccinations and booster treatment and again they should not self isolate unless they have a positive covid test result.
 If we were to stop public testing and issuing the results that would help immeasurably to stop the media hype which is causing so much anxiety and misery to everyone..

Well, it appears that the possible new treatment may not materialise; but we are already 90% vaccinated and herd immune to Covid, so what can we do now?  Possibly we should  consider :-     
1]  Admit that we are not God and cannot stop viruses mutating.

2]  Provide vaccinations to third world counties and develop Covid booster tablets to treat variants

3] Stop testing and track & trace completely as both are causing public anxiety and panic unnecessarily.

4]  Only consider lock-downs only when hospital ICU departments reach 50% Covid patients.

In electric motorbikes Honda are leading the charge but China has already produced a 15 kW permanent magnet motor using a 15kWh lithium battery which is also suitable for city runabout electric cars at a very competitive price.
UK needs to start production of these electric micro cars to limit climate change and improve city air quality.

Yes, we rely on wind otherwise gas or oil based fuel is necessary to keep the lights on. See https://www.gridwatch.templar.co.uk/ for an up to date view of the  grid generation

If a virus has a DNA double spiral then surely it is alive and can mutate.  If we freeze it can survive.

I agree that if the batteries are recharged using solar PV panels that would be ideal.  So maybe all lorry depots should be required to instal solar panels which would be a start particularly those in built up areas.
However the cost of electricity per kWhour is 10 to 20 pence/cents and long haul diesel vehicles can easily achieve this without having to carry extra batteries.  My little car engine generates 10 kWhr of energy for each litre of fuel I pump in

Look at the USA stats this month           https://www.eia.gov/energyexplained/index.cfm?page=us_energy_home      and immediately we see that amount of petrol/diesel used for transport is roughly the same as that used for generation at power stations with only 10% renewables at present.  We are not going to double up on power stations to electrify long distance haulage transport ever are we?  In cities hybrid electric cars are of great benefit to the environment but intercity is uneconomical.

Physics, Astronomy & Cosmology / Re: Are the economics of battery-driven lorries a non starter?

« on: 11/03/2018 23:36:32 »

The main problem is "If petrol and diesil are banned how will the power plants generate their power?"
There is no way of producing sufficeint power at power stations to electrify the road transport fleet.  Possibly one of the scientists on this forum has worked the gas/oil industry and can advise us on what percentage of their production goes into power plants and the percent into gas central heating/industry and percent that goes into petrol/diesel stations for transport use. Solar, hydro, tidal and wind energy should be exploited wherever possible for electric generation which can be used for domestic and industry but I am doubtful there are enough green sources to fuel transport as well and anyway the infrastructure and battery costs are totally OTT

The logistics look real scarry!!!
How many tons of batteries will a 7 ton truck need to drive 100 miles?
Are there sufficient materials in the planet earth to mine and produce billions of batteries?
How long will the driver need to waste time to change or charge his batteries?
How will the electric grid cope with producing enough power to eliminate CO2 emmissions?
If petrol and diesil are banned how will the power plants generate their power?
Power stations are only 50% efficient whereas diesel lorries are about 75%?
Hydrogen gas is not liquifiable economically; so what do we do now??

« on: 02/03/2018 07:23:57 »

In a mechanical sense energy is scalar but when we are dealing with heat and electricity the energy is absorbed by a volume [ not a length or area] of matter or even magnetised space in the case of electromagnetic 3D light energy surely?

« on: 26/02/2018 07:46:22 »

KISS is "keep it simple stupid" by applying Occams razor. But as matter is made up of electric charges and magnetic momentum with enclosure shells that obey Pauli exclusion principle without quarks, then the simplist way to deal with matter is acknowledge the basic facts and agree we live in an electromagnetized magnoflux 3D universe; a new theory indeed.

Yes, the voltage force to acceleration the particle is of course in the forward direction which I am going to designate the z direction.  Now to stop the neutron from hitting the outside wall you will have to increase the magnetic complex current/flux force around the cross section in the x,y direction and therefore the increase in particle energy will be a 3 dimensional increase dont you think? and without increasing the volume?
