If they wait long enough so that EVs are the majority of vehicles on the road, they could just prohibit vehicles with internal combustion engines from the tunnel. That reduces the need for ventilation by a very large amount. About 15 to 18 years of delay will do, which is roughly what you typically get for these kinds of projects.
In the mean time, they could look at a second Chunnel, which likely has a better payback.
Not that easy, in terms of both EU and domestic politics, and of simply gumming up the legislative timetable. The next government is going to have a lot of messes to sort out without creating a new one.
I was being serious about a wind assist since it can noticeably improve the MPG on my Prius when the wind is going the right direction, but I know that forcing air through the tunnel at that speed isn’t feasible in the first place and would probably create hazardous baffles in the airstream.
It was part of another study to look at plan for improving transport across the whole of the UK which cost a couple of million.
These plans for tunnels and bridges are nothing without improving the roads that connect them.
Boris does not have the money for this kind of infrastructure project., especially when it is not connecting major population centres. The big lump of expenditure is tied up in the HS2 rail project, whose latest project cost is £107billion.
A million or so on a feasibility project is really a political ruse. These things are going nowhere except as material to pad out his speeches. A bit of kite flying to keep the Northern Ireland Unionist politicians quiet.
An HS2 project that was recently slashed in such a way that it will still costs a fortune but won’t actually provide high speed rail connections to the North.
If this was Wikipedia, there would be a “who by?” after the word North there. When Leeds is referred to as being in “the North”, the implication is generally that it is the north of England. This is a thread on the UK infrastructure, so your comment would confuse people not from the UK.
He had the wall. That seemed to satisfy him. Even though only a small psrt was actually built. And much of that was torn down by the next guy, although maybe he doesn’t realize that.
