WBMT.....What baffled me today

While she should probably be on the Darwin Award list and is undeniably rather silly, she has lost both hands...

..a phone, I assume. So,she tried to engage with it,then ? It's been suggested it was a Bull Shark,one of the most aggressive of the species. There are quite a few species of sharks around those islands and if it was aBull shark then that is not one of the common ones. Another species thereabouts, but also not common,is the Tiger shark,also aggressive. There's no-way you'd get me swimming in waters where it's known that sharks abound.

Yes, absolutely agree.

Knowledge and the perception of risk are interesting subjects.

There are sharks in pretty much any body of salt water - even round the British coast. The species regarded as dangerous are rare but not unknown!

What I don't understand is why some swimmers in Australia go into the seas off the north east coast despite shark warning flags flying. I'd never go into Australian waters.
 
Having to jump start an electric car.

One of the cars at work hadn't been used for a week, the telematics and radio flattened the 12v battery under the bonnet. Because the 12v battery was flat, when the car was plugged into charger, the car can't communicate with the charger, hence no charging. After putting a battery pack on the 12v battery, and the car coming back to life, after a couple of minutes the charger was talking to the car and the charging began on both batteries.

Baffles me why you still need a 12v battery to run an electric car, I would have thought that everything would have run off the main batteries.
 
The electric batteries on electric cars are somewhere around 300 to 400 volts, a 12 volt battery is needed for lighting on systems etc.

Mrs Nod's iPace had a flat 12V battery on Monday. In a car wash, so we were sitting in it with the "ignition" off but the AC and radio on for 45 minutes or so while queueing and being washed. All sorts of odd behaviour as it shut off! RAC got us going and put a new battery in.

There's no reason why you can't drop the voltage of the big battery by any amount you choose, given the correct circuit.

I wonder if the manufacturers have realised that it's too easy to run down those main batteries, leaving you with a totally dead vehicle?
 
Just like ICE vehicles...
 
To my mind you need the 12V battery to power the relays that allow isolation of the main batteries when not in use.
I have a Noco Booster battery which fits under the front seat which I use to jump start the car, There is a point in the fuse box to connect it to.
You need to keep it in the car as there is only 1 manual key point on my Toyota.
I got the Booster as we sometimes go away in winter and did not want to return to the airport parking to find a flat battery in the middle of the night.
