I did some time on the flowers in the desert hydroponics program a few years ago. How it was done at time was raw sewage solids in 50 gallon tank flittering water thru powered by a 40w solar pump.
Electronic monitoring systems are more about salad vegetables reaching the supermarket shelfs on time and maximizing profits.
The chart you post on electricity imports is related to decommissioning of old nuclear and fossil fuels power stations. The new power stations to replace them were held up by planning issues & changing government policy. I believe all six of the new nuclear power stations will use light water reactors. This may change over to thorium before completion.
Using hydroponics, Humber grow cumbers and Kent grows tomatoes. In main cites they grow cannabis. Its not 1939 and we can grow food anywhere these days. In vitro fertilization means we’re no long depend randy bull in a field.
The only reason the UK food production is down was due to EU quoters.
Waters not really an issue. Most places where built on springs or streams that have since been piped and covered up. Temporary wells only take a short time to reach the water table.
Steam trains can run on wood or coal. A simple design, easy to fix and learn to use. The Paris Accords wont apply if we ever need reactive steam trains.
The national grid is more robust than you think. The UK’s hydro, wind, solar and nuclear systems meet our needs. Like the rest of the world the UK over produces electricity and trades.
The plan is design to work with 100,000 people around the UK.
For the UK to activate this plan things need to end of the world bad. With millions dead or dying costs and accords become irrelevant…. its a battle for survival.
Im sure land rovers probably have some critical uses somewhere in forestry or agriculture, but JLR is just one example, all car makers are running a limited production due to shortages.
Do we need cars to live?
In the modern world, yes.
We need cars to get to work, lorries and vans to transport goods, ambulences to take people to the hospital, ect.
Oh God….. where to start on this
Our rail network was built to transport freight not people. Few in the UK who aren’t within 20 miles of railway station. The system was mostly updated to electric over the last 40 years too. In an emergency main stations will be used for food distribution.
For those areas outside the rail network military vehicles take over.
Ambulance’s and fire engines have there own reserves of fuel.
In the last lockdown: people did work from home.
If we just cut out none essential goods our roads would empty. Lets say you don’t have a car for example:
No car mechanics.
No break down services.
No fuel stations.
No car insurant.
No car manufacturing.
No demand for materials to built or repair them.
Less road maintenance.
And you think to yourself… they cant take all non military vehicles off the road?
Yes they can. The plan was design for nuclear attack back in the 80’s. Since then new cars were design not work if there was an electromagnetic pulse common in nuclear attacks. Government grants towards steam railways weren’t hand out cause some MP’s like trains. They can be put back into service if necessity.
And while these day’s we don’t give an nuclear attack a second thought…. the plans made were the corner stone of our covid 19 response.
Somer took the comment out of context. On a river bank there no time to set up forms for concrete and there little access for delivery’s of ready mix. Its why we only use piling.
There are plans in place to ensure essential supplies are available. From food to petrol, drugs to water. The UK can go 1 to 2 years without any manufacturing or imports.
If you look around at renewable low maintenance energy projects that have pop up in the last few years you’ll have idea of the kind of planning involved.
The UK’s phone land line system is still in place and maintained while most only use a mobile phone.
Manufacturers are forced by law to ensure all goods last a min of 12 months.
Swapping from fossil fuels to electric transport is a common one we all see daily.
The UK could lockdown now for 18 months, put troops on the streets to enforce it and no one would stave or go without basic medical treatment.
And due to changing environment and weather conditions, there’s large stocks of materials in storage for use at short notice.
As for the computers, phones and more… well I hate to say this but there not really needed. There a time saver and nothing more. A man walking along the river bank can spot issues and then get on his cycle and peddle down to the yard.
