Read my previous post, I specifically said that would be something that you would protect against! Also why would you value your £400k property at £2 million, would you like to pay 5X council tax? Were you to actually use this method to set property taxes (which would then be progressive)...

I don't think you are following: You are to be taxed on an asset based on its value, you must value the asset. If you under value the asset to avoid paying tax on it someone else has the right to buy the asset from you at the amount you are valuing for tax. If you overvalue the asset you will...

There is a very basic method to value anything for tax purposes, the owner states a taxable value, if anyone offers to buy the asset for that value the owner is obliged to sell. Thus unless the owner values the asset correctly, plus a bit more to stop people buying it they will end up losing the...

One would hope that they are not totally unaware of public reaction to it, as well as professional reaction to it. The red white and blue theme is fine, the issue is that it doesn't work along a long thin object like a train. The nose design is ok (not good), the intermediate coaches is where...

Errrr have you noticed the multiple cities where autonomous taxis are running? All of the above issues are easily handled because the person hiring has to use ID and it's pretty easy to do a before and after image of the vehicle then use AI to detect vandalism or soiling and then bill them. If...

Such a debate is pretty pointless without considering what will happen in the near future due to autonomous cars. I was recently listening to the YIMBY podcast where a think tanker was talking about their plans for bus/train integration in the Hope Valley and the creation of a...

I did some prelim scaling on this site a few months back, a pipe that could supply a million people would be about 1-1.5m in diameter so relatively trivial to bury and/or conceal it above ground. The cost of desalination when done at scale is pretty low compared to the current cost of water...

The first one on the list typifies why the UK civil service and processes suck: Location Objective(s) not met Sub-criteria on which the location was assessed as not meeting this objective Rationale Albion Forest City Objective 4 – Deliverability Have identified a robust funding, leadership...

Everywhere! The long term vision is based on two technological changes: 1: Autonomous cars are going to change how we get around massively and do so well within the timescales of any rail plan set out today 2: Electric cars have essentially made extreme performance a negligible cost option...

Those Shinkansen are close to the limits of current you can pull from a 25KV line. The N700 pulls 17MW, the highest speed Chinese trains pull 20MW, Eurostar is 16MW. Hence it can go at 0.72m/s2 until about 120kph. With a battery a 16 car 400m long train could have ~65MW, which would mean it...

This is why I suggested having a drinking carriage(s), which you have to book in advance and you have to use photo ID so you can be banned if you are anti-social. Best of both worlds?

This is reminisant of the speech in The Wire about the police letting people get away with public drinking so long as the put the alcohol in a brown paper bag. People who are concealing their drinking are unlikely to be much of a problem. The most basic argument in favour is that they banned...

I think if you were doing that today you would use LFP types which have the best cost per cycle hence why they use them in grid storage. That would get you to about 150kwh/tonne at end of life. 1774889549 If we were designing from scratch the battery could actually be part of the structure...

Another way of looking at it is that if you can halve the cost of tunnelling you can have high speed rail basically anywhere you want. I wonder what the cost of a development programme would be to increase the productivity of tunnelling by a factor of two, I suspect it would be an accounting...

I have done a decent amount of pre-lim design on that; I assumed a 1.3m/s acceleration limit 22MW peak discharge for the reference train base on a 5 car class 800. The battery was sized to equal the mass of diesels + fuel on the class 800 plus an allowance for using the battery as structure and...

Not sure it would be unenforceable, at the moment anti social behaviour is pretty difficult evidence and thus combat, whereas some people drinking and being anti-social is pretty easy to evidence. Someone complains, BTP turn up the the next station stop, they are ejected from the train. Doing...

Almost sounds like we should have just put nearly all the track on a giant viaduct! 1774879198 Railways last hundreds of years, one of the reasons we needed HS2 was because all our railways were built with slow trains that don't like gradients. Future proofing the alignment should very much...

Also need to be careful to avoid a "status quo" biase, current high speed trains take a long time to accelerate to 225mph. If we start designing battery assisted trains that are limited only by steel on steel traction and passenger comfort then we can get to 225mph in around 100 seconds and 5km...

By Vectron! Loads more variables to play with: 2MWh is far from the only available battery capacity, 2MWh is a relatively small battery. The Progress Rail Joule can carry up to 14MWh admittedly on a larger loading gauge and heavier axle weight. Distributing some smaller batteries over some...

It's got 5 seats, the back ones have individual monitors, it's still more powerful than a Bugatti, has 5 seats and costs 1/20 the price. If you can live with only 1000bhp you can have the Tesla Model S which is definitely a family car, there is also the Lucid Air. Even the most basic 5 door...
