Well yesterday was the first burn of the season.  I did prime the flue just in case, and I lit it with a regular lighter 'cos I'd mislaid the gas blowlamp.  But she did us proud and fired right up and burned very nicely.  As yet still no bench, that's lined up for building this winter with luck.

Today, didn't bother priming just bypass open and off she went.  Feels like I can shut the bypass sooner but that may just be the wood is nice and dry, so it gets going fast. Anyway, the stove is burning nicely.  It's not all that cold here, mind, but recent rain made the house damp downstairs.

1-2 chicken livers and hearts chopped finely
Maybe we need to ask Burra for her recipe?  See how different they are?



Well, when I make it...  it's about like this

Ingredients:
About 1/3 Kg chicken livers, cut into smallish pieces  (we use re-purposed butter tubs to freeze the liver when we get a lot cheap from the shop and they go 3 to the Kg for fresh liver)
1 medium onion or equivalent, chopped
4-5 cloves garlic, chopped (or to taste)
If available about 100g mushrooms, chopped
If available fatty scraps from meat or failing that a decent amount of fat.  Can be lard, oil, butter, whatever is to hand.  You want a generous amount for frying, which ends up in the paté
herbs to taste
salt/pepper to taste

method:
Using an iron skillet or other pan-of-choice melt the fat if needed (or heat oil), add the onions, garlic, mushrooms and fry for a few minutes on a medium heat.  Add in the herbs, stir around nicely then add the liver.  Turn the liver frequently until it's browned all over, then reduce the heat, add a small amount of water (around 2 tbsp) and let it simmer until the liver is cooked through (doesn't take long if you cut it small).  Turn off the heat, cover the pan and let it cool.
When it's cool enough blend it with a magic wand/stick blender etc.  If you don't have that it can be done in a jug blender but that's more cleaning.  Or you can use a fork but that's a bit like work - my grandmother would approve though
Season to taste and place in jar(s) with a good lid and put in the fridge.  It keeps for at least a week in the fridge although in this house it rarely lasts that long!

modern day Vimes got sent back in time to when young Vimes had just joined the night watch.  Old-Vimes takes on the identity of Sgt. Keene (IIRC).  In due course they start the treacle mine road republic or some such and foment a revolution against the city, with the aims of achieving "freedom, reasonably-priced love and a hard-boiled egg"  - on the grounds that old-Vimes didn't much rate their chances of achieving the first 2 but a hard-boiled egg should be do-able.

They wore lilac to identify themselves.

the other aspect of drive though, the drive wheel is on the center line of the trike and has all your weight on it.  Cheap deltas tend to be 1-wheel drive, and thus the drive is off-center and your weight is split between the 2 wheels.

Better ones have either a double-freewheel or a differential.  There are advantages and disadvantages in both systems.  

The cargo trike was a prototype I built but sadly never had the funds to develop fully.  It would've allowed for carrying large items and shopping, or fitting child car seats to the front so you could carry small children safely and where they could be seen.  With modern systems now available it could easily have had electric assist as well.

Per the "tadpole" thing, My father and I used to make the Newton tricycle which was that format.  It was based on the Kendrick trikes which were made in the early 20th century although in fact Kendricks weren't that good as the steering wasn't well adjusted.  My father had a background in automotive design and built a trike with stable Ackermann style steering.  Eventually I took over the building until we had to sell the farm where the workshop was.  My father decided to pursue this after he got a "normal" delta trike and wasn't impressed with its performance.

"Tadpole" vs "delta" is a debate at least 100 years old  However, I can make a good argument based on physics for why tadpole is better:

The most unstable condition for any trike is when going fast around corners.  The biggest risk for tipping any trike is cornering fast downhill when braking.  Now, consider the trike when it begins to tip.  When the inside wheel on the turn leaves the ground, the machine begins to tip over, pivoting around the line between the 2 wheels that are still on the ground.  With a delta layout (2 wheels at the rear) that line is inclined towards the front, and so weight of the machine and rider try to tip on a diagonal which is partly sideways, partly forwards - and in the downhill-cornering scenario, your weight is trying to go forwards anyway.  Now if we consider the tadpole layout, that tipping line is inclined backwards so the forces tipping the trike over act partly in the opposite direction to the force of cornering and braking.

There's another aspect: it's easier to transfer your body weight to the "light" side of the trike with a tadpole.  If you watch racers on deltas, when they are cornering hard they have to get off the saddle and hang off the side of the machine, which is all very well if you're young and athletic.  With a tadpole you can lean your upper body over and put your weight more on one handlebar.

That's a great build, I like that you incorporated a water tank as well.  That's one thing I didn't do on ours, although we do plan a heated bench alongside it.  Intrigued that you put the chimney base at the side, which makes it stick out into the room a whole lot less.  For use the space isn't a problem but in a small room that's a very worthwhile alteration.

The LED is still going.



Furtling around in these old threads now basically CFls are dead and gone and lighting has moved on to LEDs in large part...

I'd just like to say top marks to Paul for running the light bulb test for over 10 years, and coming back to report the result 10 years later!

One thing that's happened relatively recently (probably in the last 5 years or so) is ready and reasonably priced replacements for regular tube-type fluorescent lights.  I recently got one for the 4ft one I have in the kitchen.  

O'course another thing that's come along is lighting fixtures wherein the LED light source is not (easily) replaceable and those I think are an abomination.  But the LED "bulbs" and now strip lights have come on a heck of a lot since 14 -odd years ago when Paul first posted about CFLs being crap (and in hindsight, they were: but at that time LED tech hadn't progressed to where it is now).  I well recall the first ever commercially available CFL which Philips sold which was as dim as heck for the first couple of minutes.  Now we have LEDs that make instant light, we can to a fair extent choose the color temperature of the light for different applications and provided you avoid ultra-cheap ones form dodgy stores, they are reliable.   I have had a couple that failed prematurely, likely due to being el-cheapo.  But that was always a thing even with incandescent bulbs - if you bought el-cheapo brand from the bargain store, a percentage of them failed on first switch-on.

The technology already exists for vehicle activated lights. I wonder if that technology used to only light up the signal light when there are cars approaching from that direction, would use more or less power?

Maybe not in big cities with traffic round the clock, but in many smaller communities or housing development areas, I suspect you could manage a net gain. We appear to have already done that with some of our people lighting for paths in my area. The people paths are also making more of an effort to keep the light pointed downward to minimize light pollution.

I truly wish we would do more publicity about the damage of light pollution to all living creatures, including humans, and work on reducing it. One downside I have observed about the supposedly 'cheap' LED's is the proliferation of outdoor lighting when none is really required.



A signal activated by an approaching car might be hard to make work reliably at a long enough distance.  Signals which change when a car approaches have been around for years - but if we're talking about a stop light, it needs to be on when the vehicle is far enough away to see it and stop safely.  I daresay that could be made to work.  

As for the street lighting, that reminds me:  When I first moved here about 5 years ago, looking out over the plain from my mountain there were orange sodium street lamps all over the place.  The plain has lots of little villages dotted all over it.  Fast forward 5 years and many of them including the one near our house which I'm not 100% convinced we need have been swapped to LED.  From where we are we're looking down on the plain from a few hundred feet up and there's way less light shining upwards than there used to be.  The remaining clumps of sodium lamps stand out from the rest.

I think once you get it dried out well it will settle down and behave.  Not seen any issues with condensation here recently, even with damp wood it's been burning well if not making quite the same heat so fast.  The wood's not green just damp from all the rain.  

I've been stacking the next load on the hotplate to dry out once the stove's up and running. Couple of fattish logs, a few thinner ones and some smallish stick-sized bits which I put up against the hot coals to make it restart promptly.

which reminds me, need a photo of the Tool I made.

John Wolfram makes an excellent point.  I've been avoiding those kind of lights for precisely that reason. In my house though there's not one incandescent light.  For my work spaces I like a cool or daylight light and that's inefficient to do with incandescent, even with the modern ones with a halogen lamp inside: There used to be special "northlight" bulbs for artists with a blue glass envelope and you needed about twice the power rating to get the same amount of usable light.  

Other lights are a mix of cool or warm, depending on what was to hand and where they are fitted.  My partner prefers the warm one for a bedroom light. In the kitchen I have a 4000K 4ft fluorescent tube replacement which uses less power than the original 4ft tube did to give more light, it doesn't have a starter (it comes with a plug-in "starter replacement" which I guess simply connects the power to it) and has the added advantage of instant full power light just like the other LEDs.

Going back to Paul's original point about altering other, much more power-hungry aspects of your life such as using a washing line or clothes rack vs. using an electric dryer, or washing up by hand in a sink and putting the dishes on a drainer vs. using a dishwasher: I think the point is that swapping out the lights is a low-effort thing that most anyone can do at more or less zero inconvenience.  Making those other changes would have much more effect but many people don't do that because they don't want the extra effort.

There is one aspect of LED lighting where I can see a definitive benefit in electricity cost and that's traffic signals.  Some years back they began converting all the traffic signals in the UK to LED lamp units.  The old signals used a 250W incandescent bulb in each of the 3 lamps (I know because I asked a chap who was changing out a bad bulb once).  Consider a simple 4-way cross road.  In the UK that will have 3 signals facing each direction: one either side of the road at the stop line, and one on the opposite side of the road so you can see it when parked at the line.  That's a total of 12 signals on that one junction, and all of them have 1 light illuminated 24/7* for an ongoing consumption of 72KWh per day, or 26,280KWh per year for just ONE road junction. 26MWh of energy for ONE road junction!

Now consider the same junction with LEDs. Even if the LED lamps are 25W which I doubt, that would still cut the power consumption by 90%.

It's not the same everywhere as the lights differ: for example, I believe US rail signals use a mere 35CP bulb due to clever design of the lamp.

However I found this webpage about traffic signals in the city of Yakima.  They had 100W bulbs in their signals and their LED replacements are 15W, and the bottom line is that they cut the energy use per 100 intersections by about 80%.

* OK in the UK they have a red+yellow phase, but that just makes the consumption higher.  Other places only have 1 lamp lit at a time
