Dyson has stated that it will not be a mass markets car but will compete with top end BMW and Merc's so expect £50 - 80,000. Like all his products very expensive although well made.

Easy solution - Oyster card as used in London. Or like in Rome swipe your card when you get on and swipe it when you get off.

No cash transactions.

90% of passengers round our way are pensioners who just swipe their bus pass.

Nissan Leaf 5 star rating. https://www.euroncap.com/en/results/nissan/leaf/32742

Not so difficult even with a big battery.

Erfolg. To answer your point on crash testing.

Tesla Model 3 crushes NHTSA's crash testing with a 5-star rating - CNet

20 Sep 2018 - The Model 3 received top scores in every category tested by NHTSA, including standard safety equipment.

Go to telemetry page and if RxBt not displayed scroll down and click add sensor. It will now display on your screen top lefthand corner. You don't need any other sensors for that reading.

Just look how quickly we have gone from almost all i/c planes to electric. I would guess there are more electric now which happened in a very short time.

Peter Did you read my post about the Super Hub above. The chargers will operate from an enormous battery facility and will not draw directly on the national grid. Given we have hundreds of wind turbines in this area I expect they will mostly charge up when the wind is blowing. They will also be able to power 6000 homes for 24 hours. We also have a very large battery station in Cleator Moor. Tesla have install a massive battery station in South Australia and after years of constant power cuts that now no longer happen. These batteries are charged from wind turbines and in the short time they have been operating (a couple of years) they are well on the way for paying for themselves.

This super hub will charge 100 vehicles at the same time

A very interesting project with lots of information and data. Shows what can be done with simple and cheap parts.

Thread: Durafly (Hobbyking)new Canadian Vampire compared to old Vampire

I am on my third two originals and the Canadian. The Canadian comes with reinforced booms. I find it better to removed the retracts and hand launch and then she is a real flyer. I use 2.7 4S batteries. With the first one I had a radio problem when flying straight and level it suddenly dived to the right into the ground. The second just became worn out with constant use so retired. If leaving the retracts on the front nose wheel needs attention. I hit a rough patch with the Canadian on take off and knocked the nose wheel off. Having said that a great plane to fly and that's why I have had three.

Went for a 2 hr test drive in the Nissan Leaf yesterday and think it is a very nice car, a bit bigger than I thought. It had plenty of room inside with a large boot. What impressed me was the e-pedal. After the first couple of miles I switched it on and after that never used the foot brake once. I drove on country roads, in town and on duel carriageways. Stopping at junctions, in traffic and parking all so easy. It would be good if they could put such a system on i/c vehicles. It has all the equipment that most cars have now, Lane hold, stops if it thinks you are going to hit something or a pedestrian and all round cameras etc. They told me they had 12 being delivered yesterday and if I ordered one depending on spec I may get it for the 1st September.

Peter Christy.-

With the creation of the United Kingdom Atomic Energy Authority (UKAEA) in 1954, ownership of Windscale Works passed to the UKAEA. The first of four Magnox reactors became operational in 1956 at Calder Hall, adjacent to Windscale and across the River Calder, and the site became Windscale and Calder Works

Calder Hall, first connected to the grid on 27 August 1956 and officially opened by Queen Elizabeth II on 17 October 1956,[40][41] was the world's first power station to generate electricity on an industrial scale (four 60 MWe reactors) from nuclear energy; supplied to the National Grid.

I often think there is short term thinking. 15 years ago I installed solar panel before feed in tariffs etc. I bought them outright admittedly at about half price. Everybody was telling me that it would take 20 years to pay for them and would cost me in repairs. At the time I was paying 3.5 pence per unit of electric. Today I am paying 16 pence for the same unit. Given the price of electricity has gone up by a factor of four then my payback time must have come down by the same factor therefore a payback time of 5 years. OK, I know that's not strictly true given that it has not been 16 pence for the full 15 years. My electric supply company send me a yearly statement of my usage and it says my usage is 50% less than the average similar homes. At the same time I installed thermal panels (hot water). From April to May we very rarely switch our boiler on because we have all the hot water we need. It is difficult for us to convince our energy supplier that we do not use gas during the summer and last year they insisted on changing our gas meter as they said it must be faulty.

Percy, love your sense of humour.

Nissan reuse batteries. Erfolg Nissan batteries have an 8 year warranty and if they fall below about 80% they are replaced under warranty.

 

Reused Batteries. xStorage gives Nissan's electric vehicle batteries a 'second life'. The battery is used as a home storage unit, which you can control, deciding how and when the energy is used.

.Tesla use electric motors that have two moving parts, and single-speed “transmissions” that have no gears. The company says its drivetrain has about 17 moving parts compared with about 500 in a conventional internal combustion drivetrain. Plus more in the ic engine. The Tesla system is virtually maintenance-free.

A single car has about 30,000 parts, counting every part down to the smallest screws. Some of these parts are made at Toyota, but we also have lots of suppliers that make many of these parts. The 30,000 or so parts use different raw materials and different manufacturing processes.
