Getting there – slowly
Since my last post, the stitches have been removed from my shoulder – a far less painful operation than I had anticipated. There are still the dissolvable stitches poking out of the wounds and they catch on my shirt, but hey ho!
Yesterday was my first day of physiotherapy. Now, I am no fan of physio as it has caused me no end of problems in the past, the worst giving me sciatica on two occasions within three weeks. I do not recommend sciatica.
But yesterday’s session was gentle. The exercises I have been instructed to do are gentle and quite easy to do, although after doing them, it feels like the muscles in my shoulder have been ripped apart.
Oh, they were.
I am still to keep my arm in a sling for the time being. Its own weight on the repaired muscle could cause damage. But at least I can use my hand now.
The only problem now is that I will have to go through all this again with my other shoulder.
Lack of Posting
I apologise to those of you who regularly visit this blog, hoping to find a new post.
But, following a car accident last year, I am undergoing treatment for the injuries received, the latest being the repair of one of the major muscles in my shoulder. Prior to this latest surgical intervention, I had my wrist repaired, involving a bone graft and a pin.
I hope that I will be able to resume posts when I have the use of both arms again.
The Pug is efficient!
Relating to my previous post about my new acquisition, I have worked out the fuel consumption.
I have only put 30 litres in the car so far, and have done mainly short trips, but so far, it is returning about 49.6 mpg.
I am very pleased with this result, with petrol hitting £129.90 per litre.
Decision Made – Probably
I have given the little Peugeot (see previous post) a good look over. I have driven it and I like it.
I will be sorry to let the Scoobie go, but it is, in all honesty a bit too small for my needs, and the non-standard exhaust would suit someone 40 years younger than me – it is loud.
The only problem with the Pug is that it misfires when cold, when accelerating or when the engine is under load such as going uphill.
So I changed the spark plugs – when I eventually found them, hidden as they are at the rear of the transverse engine and under the coil pack.
This is the first petrol engine I have worked on that does not have a coil, distributor and individual HT leads to each plug. The coil pack sits on top of the spark plugs and is connected to all of them rigidly.
Working with a wrist that was until recently, broken, and torn tendons in both shoulders does not make bending over the small and low engine compartment any easier, but as the last new plug went in, I got a sense of satisfaction. IT was short-lived as the engine still misfires. So it has to be the coil pack.
At least I now know what it is and how to get it off the car!
Electronic Cigarette? What? Why?-
Having been a smoker of cigarettes, pipes and occasionally, cigars for over 40 years, I was a little dismayed when the surgeon told me that I had to give up smoking if I wanted the broken bones in my wrist to knit.
Apparently, the effect of smoking on bone healing is that oxygen flow is limited as there is a lot of other muck in the blood, notably carbon monoxide and oxygen is needed for the bone to heal. This is a layman’s grasp of the situation.
Knowing that I would almost certainly suffer arthritis in my wrist if the bone did not heal properly, I agreed and the surgeon said he could fit me in within the week.
As soon as I got home, I searched the Internet for e-cigarettes and decided on a particular brand, only because their liquid nicotine extract is made in the UK and ordered all the gadgetry needed to smoke without smoking, so to speak.
The parcel duly arrived and I put away my tin of rolling tobacco, filters, papers etc and started up this new toy, expecting very little in the way of satisfaction.
I was ready for cold turkey – but it never happened.
I was admitted to hospital and the operation to repair my scaphoid was carried out, including a small bone graft and the insertion of a screw to hold all the bits together.
When I came round, I was gasping for a fag and remembered the e-fag in my bag.
I took myself for a little walk down the corridor of the hospital, gadget in mouth. The particular one that I chose glows blue when drawn upon, so it cannot be mistaken for a “proper” cigarette – and no one challenged me.
That was last November. I have been experimenting with the e-cigarette, using different strengths and flavours of nicotine extract.
As luck would have it, within a week of my being discharged from hospital, my mother was admitted with a blood clot on her lung.
Now, Mum has been smoking for about 70 years and was not about to give up for anything or anyone. Except of course, in hospital, she was not allowed to smoke.
When she was discharged, she was gasping for a smoke and I gave her an e-cig.
She did not believe that it could replace the pleasure she got from a real cigarette, but soon found that it was, in fact, better!
So, we have both been using these gizmos since before Christmas and Mum has not missed her cigarettes.
As an experiment, I have had the odd real cigarette but can honestly say that I did not enjoy them.
I have opted to refill my own e-cigs, and that is a bit fiddly, especially with a plaster cast on my hand. I could have bought ready-filled tips, but I was not only looking to give up smoking, but to save as much money as possible.
So, every other evening, I sit with a bottle of nicotine mixture, a syringe, a paperclip and some tissue, and fill the used tips. In fact, it takes only about five minutes. Everything is provided by the e-cig company, including surgical rubber gloves to protect the hands against the nicotine concentrate, which, I understand, can be dangerous if it comes into contact with the skin for a prolonged period.
So, what is an e-cigarette?
The one I use comes in three parts, the rechargeable battery, an atomiser and the tip, which contains the nicotine extract.
The battery can be charged in the USB port of a computer, in a car’s cigar lighter, or, at extra cost, from the mains. Mum and I both have three batteries, so when a battery is discharged, another two are always available, as long as I remember to put them on charge.
The Cost?
I have worked out that between the two of us, we spend about £22 a month by refilling our used cartridge filters. If I were to buy ready filled cartridges, the cost would rise to about £50 a month.
Either way, compare that to our monthly cost of traditional tobacco products, about £220.
So, in conclusion, the e-cigarette gives me as much of a kick as an ordinary cigarette. I am not inhaling carbon monoxide (as I am not burning anything) or the other added chemicals that I would get from a “real” cigarette. There is no smoke, so an e-cig can be smoked in places where smoking is prohibited. And I am saving a bucketful of money.
The Kids Cook Dinner
During my last visit to Kenya, I was at a loose end, so thought it might be a good idea to introduce some of my cooking methods to my Kenyan friends.
Of course, the first potential problem was to find the ingredients that I am used to. In the event, all but cheese was readily available and I found that Nakumatt has a cheese counter where they sell cheddar which is just about acceptable. So, macaroni cheese is was going to be. The second problem is that I am not used to cooking a meal for eight on a single gas ring.
Benta (8) and Esther (13) were to be the cooks and I would guide them, but everyone, kids and adults alike all crowded around the single burner gas stove to watch, and in the case of the children, sneak a few bits of cheese from the chopping board!
After cooking the macaroni and storing it in a hot pot, the sauce was made, with much fussing around (and dipping in of fingers to taste it).
When everything was ready, the meal was served, pasta first then the sauce over the top. I am happy to report that it was rather popular.
I also introduced some herbs/spices into the household, the first being ground black pepper. Unfortunately, this was carried up by the steam from the cooking and invariably straight up the nose of whoever was cooking, causing a sneezing fit!
I eventually found black peppercorns in a grinder, which solved that problem.
Goat meat tenderises nicely when marinated in Guinness for 30 or so minutes.
I showed the kids how to make rice crispies chocolate cakes. Unfortunately, these lasted only about 5 minutes.
Still, the kids were happy and I hope I helped with varying the usually diet a bit.
Other Benefits from Push-Pull Pest Control
At the beginning of this year, I posted an article about Push-Pull Pest Control, where to protect a maize crop, a farmer plants other crops, particularly to prevent damage from stem borers, the other crops being silverleaf desmodium (the push) and napier and Sudan grass (the pull).
I have since been reading accounts of Kenyan farmers having adopted this method to control stem borer moths and striga weed, reporting that their crop yield for 1/4 acre plot has increased up to six-fold.
But, there is a side-effect. The desmodium is good cattle fodder and these farmers find that they can acquire or increase their head of livestock.
I am happy to see that push-pull technology is slowly being adopted in areas of Kenya (particularly Western Province and Nyanza) that are afflicted with these pests, but it needs to be promoted more vigorously so that all farmers in Kenya, or Africa in general can use this very effective method of pest control.
Imagine if all maize farmers could increase their yield by a factor of six!

On Anaerobic Digesters and CO2
Regular readers will know that we built a prototype digester last year. It was relatively successful, but not very efficient due to the design, which was based around cost rather than gas production.
It was a proof-of-concept model.
Since then, I have designed, but not built models that should work a lot better, and I have also done some reading on the subject, since I can do little else with my wrist in plaster.
One thing that I found out recently – the gas produced is mainly methane [CH4], but there is a lot of carbon dioxide [CO2] in the mix. This could prove a bit of a problem as CO2 is, of course, inert and is even used in fire extinguishers, not the sort of gas one would want in the supply to a burner of some sort.
The answer, of course, is to clean the gas to remove at least most of the CO2
I believe that passing the CH4/CO2 mix through water does clear out the CO2, leaving a much purer gas fuel.
There is also the possibility of the fuel gas containing sulphur and passing the gas through a stainless steel scrubber will remove this.
However, anaerobic digester design, at personal/small community lever, is a very inexact science. Lots of people are building them, some are successful, others less so. There is a plethora of information on the web, some of it contradictory, so it is a very confusing field.
So, is there anyone out there with experience of building digesters who can verify (or otherwise) the necessity/efficiency of CO2 and sulphur removal?
You input would be most helpful and time saving.
