I have hired one of these off the street in Gothenburgh and i have nothing but praise.  They must be safest form of transport with power.  More safe than electric bikes and mobility scooters.  At worst you can just jump off and throw the scooter down.

I guess the problem could be when there are large numbers of them.  I think they should be kept to the roads and preferably cycle lanes marked with direction of travel as per bycycles (of all ages)  and even horse riders (of all ages)

Hello Rob

Ref "  Theres no glycol left in our system at the moment, I’ve just been refilling with water for the last few months. "

I installed two systems. Mine and next door. In the first few weeks of Navitron selling the panels. Never had Glycol
in the systems. Might be a problem further North.  snow

I think I’ve fixed it:-).  The unit has two crystals, 32khz for a real time clock, and 8Mhz for normal running.  The 8MHz one didn't always start when I powered the unit from dc, needing a touch on one of the pins to get it going.  I bought another (31p farnel), and it starts up every time now.  I’m guessing the old part esr (equivalent series resistance) increased as it aged, until there is insufficient gain to guarantee oscillations.
Fingers crossed, if it lasts 2 weeks it’s good.  If not.... gah.  Theres no glycol left in our system at the moment, I’ve just been refilling with water for the last few months.

I am around the same usage as KDMNX in July 21.31. You seem quite a low power user compared to my usage. I am using an ASHP, there are 4 of us here, so mainly 3-4 showers a day. The ASHP uses about 3 to 3.3 kWh for about 15-30 mins to reheat the water after each shower. Just something to bear in mind timing-wise. Not a problem in Summer as export about 60% some days.

The 3 batteries ties in nicely with the lux input/output thresholds lux input/output is around 3.6 kWh and 3 batteries are around the same. I got 6 for 2 reasons, firstly I was going to get parallel systems for more max output, but it's on hold, for now, to see how it works over winter with 1. Secondly, I wanted more storage based on my high usage, so I could pull from the grid and cheap rates.

So, Voi (Swedish company) have an interesting page..

Laying out reduced speed (automatically) parking zones etc...

Also unlike lime in europe they are requiring *cough* you to be 18 or over to use their kit.

Lime in Germany require you to be 14+ it was recently amended.

If we rely on folks honesty then figures for vandalism, accidents & the like are going to be heavily skewed as folk tick boxes on an age compliance (& provisional / full license).

The International Transport Forum (ITF) published a report in February 2020 entitled ‘Safe Micromobility’, which compared the safety of electric scooters with other vehicles. The report includes electric scooters in its definition of ‘Type A micro-vehicle’ due to their low weight and top speed of less than 15.5mph, and states,

“A trip by car or by motorcycle in a dense urban area is much more likely to result in the death of a road user – this includes pedestrians – than a trip by a Type A micro-vehicle. A modal shift from motor vehicles towards Type A micro-vehicles can thus make a city safer.”

The report goes on to state that a road fatality is not significantly more likely when using an e-scooter rather than a bicycle, and the risk of an emergency department visit for an e-scooter rider is similar to that for cyclists.

Among the 10 recommendations the ITF makes, the report suggests that street layouts could be altered to make urban traffic with micromobility vehicles safer, along with suggestions for safer vehicle design and operation.

Bet it's fundamentally the same as the 800V one on the Taycan with reduced margins - they'll both be using 1200V power electronics.

Blimey.  Audi are you watching?!

900v drivetrain sounds interesting.

Running the pumps few a minute every day is to help prevent them from jamming.

Slightly off topic from OP.

I have dealt with a similar failure of a same type of divertor valve fault in a Baxi Platinum combi. Wet the kitchen and trashed the actuator motor too.

The trouble with combi s is the divertor valve and plate heat exchanger. Your Main boiler is basically a budget baxi duotec/ platinum. Baxi just use a different warranty, price point and a cheaper aluminium main heat exchanger in the Main brand ( Quite a reasonable boiler).

Your plumber is probably right. The problem is that we all have our favourite brands of boiler. A lot of the big installers ( Those who advertise on the TV) like to fit market brand leader but won't mend them later.

Personally, I fit the Glow-worm, some people don't like them, but I think they are good all rounders. Great controls too. I fit ideals too sometimes ( same divertor valve as the Baxi) .

The best divertor valve (Inherently Leak proof) is that fitted in the Viessman and Worcester Bosch combi s (That is the only good bit of a WB imo.)

Seams that corrosion inhibitor additive can lead to premature divertor seal failure, but so does corrosion and sludge deposits too. Therefore must have a leek free system, good expansion vessel and non drip PRV along with a good magnetic system filter to keep to particulate levels down.Other things that dont help matters are very hot water and high system pressures.
