GB News Criticized for Extensive Focus on Muslims Amid Controversy Over Reporting
You are correct to a certain extent. The UK has 6,500,000 people of workable age who are claiming benefits and this knowledge is a draw for the Illegal Economic migrants. -

Electric Vehicles in Thailand
There may be no major differences between a wall and portable chargers other than outside physical design, input electrical wire/plug, etc. Both types do the same basic thing which is monitor/control the amount of amps flowing to the EVs in conjunction with the EV's onboard charger. A wall/portable charger does "not" rectify 220V AC to a DC voltage.... so, it's not really a charger at all. Technically it's "EV Supply Equipment (EVSE)." An EVSE is basically an electronic safety switch/breaker which communicates with the EV telling the EV onboard charger (this is the real charger) that the EVSE will only honor a certain maximum amperage flow/pass-thru like 32A, 16A, ec., "and" the EVSE will also monitor for earth faults/shorts/etc. The EV onboard charger must agree to not request more than a certain amperage as identified by the EVSE. When the onboard charger and EVSE come to agreement the EVSE will then engage its high power relays allowing AC current to flow thru it to the EV onboard charger where the AC to DC rectification magic occurs....that is, the EVSE turns on it's electric spigot allowing AC current to flow to the onboard charger where it's converted to DC voltage to charge the battery. And the EVSE monitors the current flow in coordination with the onboard charger. If the onboard tries to draw more current than the EVSE told it earlier then the EVSE immediately breaks/stops the current flow....the EVSE acts like a circuit breaker because the onboard charger broke its agreement with the EVSE that the onboard charger would not draw more than X-amount of amps. As to other differences between a wall or portable EVSE like does it have a Wifi connection, RFID on/off, display, selectable amperage max, mobile app, etc., well, that all depends on the manufacturer. And if you take the cover off a wall EVSE you will find a lot of empty space and only see a small circuit board or two inside with some connectors, relays, and wires. In a portable charger it will have very little un-occupied space, a "smaller" circuit board, etc.,...and its input power cord comes with a plug attached....it could be a plug that plugs into a typical household outlet, a big 32A special plug, etc. Regarding wall EVSE that cost Bt30K-50K those must be brand name premium (i.e., over-priced) EVSE and/or that pricing includes "installation costs" where high amps wire, circuit breaker, upgraded electric meter, etc., come into play. Even if you buy a Bt6K 32A portable EVSE if you plan to run it at 32A or maybe even 16A you may need to upgrade your house wiring, add circuit breakers, etc.., which cranks up the total cost. And you can get wall mounted 32A chargers for a LOT less than Bt30K...just for example the BYD ESVE for under Bt10K posted at the bottom. And you may be wondering why I said ".....maybe even 16A...." Well, if the 16A outlet you plan to run the portable EVSE on is on a circuit that is already powering other outlets which you have things like refrigerators, microwave, lights, TV, etc., plugged into already then than circuit is already pulling X-amount of amps....let's say 5A just for discussion. Plug-in the portable EVSE set to 16A max....add 5A and you are now at 21A....even more (maybe around 8A more) if you turn your microwave on for a few minutes. If the main breaker box circuit breaker all those electrical devices are hooked to say a 16A or 20A breaker then that breaker is going to trip within a few minutes to a few hours...probably trip while you are asleep and you wake up to a warm refrigerator, the EV stopped charging, etc. And there is even the possibility of overheat wires. Now what do you do since the circuit breaker tripped? Well, you try setting the EVSE to a lower max amps....maybe 13A...maybe 10A...maybe all the way down to 8A. Get down to 10A or lower then that no better than the 10A portable EVSE that probably came with your EV. So, be sure to fully evaluate....know the max amps....of the house circuit you plan to use the EVSE on. You may find out you will need to have some higher amperage wires, circuit breaker, etc., installed if you want to charge at 16A or 32A. Every house will be different as to the electrical circuits it has running around the house and what those circuits power. -

Yes, and they should also recognized the problems with doing that in the street. Look at me, Look at me. oops, it's gone. -

Thaksin Announces New Anti-Drug Task Force Led by PM Paetongtarn
It’s obvious that illegal drugs are a problem the world over. It’s becoming worse every day and luring young kids in to the business and or becoming addicts very young. Thailand made a huge mistake in legalizing all these sleazy shops that have opened on every soi corner. It has attracted the worst type of tourists imaginable. Look at Marseille in France, Paris, Lyon all over. Drug cartels have taken over. Kids of 12 are missing school to work as “ lookouts” for their boss. 2 children were killed lately . 14 yr olds arrested for shooting someone who didn’t pay the goods. There are so many reasons to stop this business. Why work, why study, when you can earn 3 , 5 or more thousands euros a month for 2 or 3 hours of work a day. It’s breaking down families and society as a whole. It’s out of hand. -

Foreigner Wrecks Chiang Mai Stall After Smoking Ban Warning
Anyone who shows disrespect of others and the norms has no place in mixing with society. Oh, maybe you like the dickhead think that you are superior to others. Just another whimp.
