Some feedback: - found the image on landing page confusing, expected to be able to click the items in it - pricing 'free until we launch'. This would scare me off - if people are going to start using your platform they need some i

Do you have many transport projects on the go currently? One that I always thought would be interesting is looking at optimisation of the distribution of the Santander Cycle Hire bikes. These are redistributed to expected demand, but moveme

Agree. Also surely one of the limitations here is technical / usability. One of the big features of Zoom is transcoding streams from all manner of devices and sending them to all manner of devices. Doing this on the fly is still comput

"The transport HMS Chepstow Castle, carrying troops from New Zealand to the front, coaled at Freetown on August 26 and 27; within three weeks, out of her 1,150 men, inﬂuenza struck down nine hundred of them." This doesn't sou

Wouldn't you really need a log scale or further interrogation to make that claim? To me it seems mortality dropped about 40% in last 50 years which is quite substantial.

Designing high speed rail for large thermal ranges is non-trivial as the forces can be very large. Solutions can be very expensive (e.g. slab track), and therefore it may not be appropriate to build this out for 2 weeks of the year.

Ah yes, they are both very nice structures that would have taken some good engineering at the time. I wonder what would have been used as the impermeable water barrier - puddle clay or similar?

I'm sorry but as an engineer there is no way aqeduct is from 1670, it looks mid 1800s (and definitely no earlier than 1800). Edit: Google shows canal du midi is indeed from 1670 but this aqeduct section is later, completed in 1858 (the

I suppose you could have 'trusted devices' where upon taking pictures/videos a hash of the file is committed to blockchain. Although a privacy nightmare. This obviously wouldn't solve the 'no fake videos' probl

Unfortunately not and that is one of the main issues. Even if we had limitless carbon-free energy there would still be significant carbon outputs directly from the production process. The article shows one possible way of reducing this for

It's not people voting against May, it's just that nothing _could_ command a majority at this point other than a fanciful option that takes the best of EU (no economic shock) but strips out unchecked migration and European courts.

2mm is fine and normally within measurement error. However, buildings should be designed to not fail disproportionately, so there isn't sudden failure such as like with the Miami footbridge. Design errors can lead to sections being ove

It definitely is true, these are electrified lines and rolling resistance is low. For equivalent distances elsewhere emissions are 80-90% lower with rail over air transport. With the potential for solar in SoCal there is no reason this coul

Misleading as this is just the direct marginal costs, you have to account for the indirect costs. Weather and water obviously play a massive factor in wear, a road would not last 1400x longer if used by 1 car rather than 1 semi.

The ducts get very large, so trying to fit them in existing infrastructure is a big challenge. Also consider that much of original 'spare' space has been repurposed for additional systems (CCTV, PA, additional power etc). It'

Grenfell's quite different to this. More similar is the Hammersmith Flyover where they recently had an issue with a post tensioned 60s structure, and corroded tendons snapping. In that case drastic action was taken, closing the structu

I've been involved in modular buildings in the past and one area that seems to end up informing design choices (in a negative way) is the size of elements that can be readily transported from a central facility to a site. Having bays o

Where does this size argument arrive from because it comes up consistently on USA v elsewhere arguments? 95th percentile densities are no more than europe. The population of USA is more than 30x Finland and we are talking about laser scanni

Well this isn't correct either. It's not fully automated in the sense that doors are still operator controlled. LIDAR is completely unrelated and is used for asset management rather than signalling.

I suppose the economics of it comes in to play in a similar vein to mailchimp, the lower the pricing the more scammier clients and the more IPs they lose to blacklists.

The article goes into this though, these challenges are something that comparable international projects have faced in much worse ground conditions (which extenuates the issue). The magnitude of cost difference does not stem from engineerin

Agree with the spirit but this isn't strictly true. Some in Japan do, even London will be paid for fully by fares in next couple of years as the government pulls the grant.
