500 Year Vision

Experiments with sustainable technology in South Bohemia, Czech Republic. A British couple renovating a country house & thinking about our environment.

Water woes, shocks and explosions.

August1

So at last, last month, we finally caught up with (what passes for) civilisation.  We had our new (second hand) Whirlpool washing machine and a shower attached to the boiler in the bathroom. It felt really great. For a glorious moment… then I got electrocuted by the tap on the shower – (luckily before I’d started running the water). The washing machine had blown up and taken out the boiler with it – leaving the taps and shower live. At least it was me, rather than a visitor who got the shock.

The problem was that a plug in the bathroom (which was part of the old wiring) had been wired the wrong way – reminiscent of the copper wire that had been used to bypass the fuse system (which we discovered in the early days). Luckily nobody died either time – but it does leave the lingering impression that the house had been booby trapped.

So, yet again we are without hot water and a washing machine. When the weather is good we’re fine as we have the solar showers and bath outside. The repair cost for the boiler was greater than the cost of the boiler itself – so we’ve ordered a new boiler with three inputs – meaning that we can heat the tank from a back boiler on a stove, from a solar system input as well as a backup in the form of electricity.  That’ll be arriving next week, and the Whirlpool washing machine has been repaired – they phoned us to ask us what the maximum we were prepared to pay for the repair would be – then they charged us this amount. Our cheap second hand washing machine has stopped being.

Still… we hope to rejoin the 20th century again this week.

What do Minstrels and our floorboards have in common?

July22

Wanting to stay as close as possible to nature – we decided to try Shellac as a varnish on the stripped floorboards. This is bought in the form of flakes and dissolved in a very strong alcohol – it would have been nice to use a local alcohol – and would have certainly smelled more pleasant, however it needs to evaporate completely – so Slivovice was not the thing to use. Shellac is a secretion from a bug, which is then scraped off the trees and processed. It is the same bug which is used for the production of cochineal – and in fact, Shellac is used in food production – such as over the brightly coloured coatings on Skittles. Yum. As with anything in our immediate environment – including skin creams, the fact that it comes in an edible form gives me confidence that we’re not inadvertently poisoning ourselves by using chemicals which have not been tested a, in combination with other chemicals, and b, over the course of lifetimes rather than weeks to check of ill effects. Shellac has been used for hundreds of years in the form of French polish. It has a long history as well as uses in the food industry.

We have two litres of Shellac made up, I’m interested to know how far this will go – so far I’ve used it to treat the areas of floorboard which have woodworm damage – long dead woodworm which has attacked the wood from the sides, rather than the top – suggesting to me that the woodworm was in the wood when it was cut into planks.

The filler I made up with sawdust and shellac hasn’t been successful – perhaps because the sawdust wasn’t fine enough. I was hoping I could fill the woodworm holes with this mix, but it’s not quite right yet. It’s nice having the chance to experiment anyway.

Whitewashing in the truest sense

July21

Most people are aware of the quantity of man-made chemicals we now carry in our bodies – with all sorts of nasties even being present in breast milk. Fire retardants are particularly vile, and, as with most modern day decisions, ‘you pays your money and you takes your choice’. Fire retardant on pillows: you are less likely to set fire to your head, and more likely to get cancer.

Whitewash is essentially a mix of calcium hydroxide, chalk and water. I can buy it ready made for 165kc for 15kg – so it’s much, much cheaper than paint. It appeals to me for the same reasons we’re experimenting with Shellac. Once I’ve got the basic repair and decoration finished I plan to experiment with pigments added to the whitewash – though I will certainly not be using pig’s blood as they did to produce ‘Suffolk Pink’. Nice. I was thinking more along the lines of leaves and berries for a hint of colour.

I’ve been painting with the whitewash for a few days now. If you get it on your skin it’s incredibly drying – it’s important to wash it off quickly or your hands will become dry and cracked (rescued only by the Body Shop’s Hemp hand cream).  I’ve been using a domestic whisk to mix the paint – which settles over time into a watery layer over the heavy, cream cheese consistency, lime. Once mixed together thoroughly this should have the appearance of yoghurt.

A few days ago I used paint which hadn’t been mixed properly thinking that it might save me time on additional layers – it went on well, however when I came back to it today I found that it had cracked into small squares and was loose or peeling off the walls on about half of the places I’d painted. My only excuse was I was rather unwell with a horrible cold, but it was a bad job. Mike said it could have been the paint itself, but I know that I tried something different and it’s worked well in the other rooms. Lesson learnt. I then had to sweep down the walls again, vacuum up the mess and start again. The brilliant white emulsion is faster and doesn’t rub off on other things (like a paint made of chalk does), but I’m far more concerned with our health and the health of the house – why add VOCs to your home if you don’t have to?

Global Agents for Change visit – accompanied by a huge storm.

July20

The house feels verry verry quiet.  We had been gearing up for the visit of our 24 cyclists for some time… clearing out the courtyard for the hog roast, building the frame for the solar showers and laying down the hosepipe covered by tin guttering to heat the water, and clearing away as much clutter as possible.

Friday was a wonderfully hot day, but as the first of the cyclists arrived, so did the first signs of bad weather – a storm cloud made it’s way over from Tabor as they did.  As more people arrived, so the rain became heavier.

The last cyclists had not been able to find our road, and instead had stopped at a farm in another village which had the same house number as ours.  The perplexed farmer had no idea why two girls who spoke no Czech were pointing to their T-Shirts and expecting to put up tents in his garden.  Shortly after their arrival here, as we were serving the food, the light show started. A wonderful, wonderful lightening storm – if you weren’t trying to cater for 36.

As well as the Global Agents (Gala’s description), we also had Olivier and Arno – French couchsurfers, and Janni from Finland. Our workaway.inf0 guest Jessica, Shane, Nat and Keith from The English Centre, Tabor. And of course, Pig John (as he now wishes to be known).  After the barbecue we watched the storm from the porch.
