I read this a a rubber roof rack.

Have you tried putting the phone at the focal point of a satellite dish and seeing if you can get a better signal.

No, but as I was paying for a mobile (£10/month), a fixed line with BB for £35/month, but now paying just £20/month with GiffGaff for unlimited downloads, calls and texts, I make that a a £300/year saving. Got to be kept in perspective, I had a dreadful broadband connection and no immediate plans to upgrade the local exchange.

My cheap MotoG has built in WiFi Hotspot software, I can stick it 20 metres from the house and it works well. I am lucking in that I have a decent 4G transmitter less than a mile away. I was over an Joe90s build and it had no signal, maybe my next visit over there I can play with it a bit more (if I ever get invited back, apart to apologise). If going doing the 4G route, it may take a bit of mucking about and an old satellite dish to see what is going on. I also use an free O2 service that that allows me to connect in cafes and other places. May be worth seeing if there is a map of the coverage.

I have gone to 4G and any day now the landline is being disconnected. There are issues with streaming video, but I can live with that (my contract drops to 3G once I have used up my allowance, except between midnight and 8AM), but it saves me £300/year and I can now just take the laptop anywhere and do some work.

My second favourite shop, two books a week is cheaper than a daily paper.

A Marguerite Patten cook book bought in 1981, still earning a living from it. My first PC, earned a living from that too. My Sun bike (got the frame for nothing), many happy months cycling across Europe and Africa on it. Bosch washing machines, they are so much better than Hoover and Hotpoint.

What!!! A grand more than my fridge from Currys. If I cannot afford the best (and I can't anymore), then I buy the cheapest.

Concrete is a composite material i.e. made of many things. It is not unusual to put chopped glass fibres in it. Hemcrete uses hemp fibre, CRP uses carbon fibre, brake pads used to use asbestos, really all comes down to the properties wanted.

If you are quick, get this weeks New Scientist, it has a section all about water recycling.

Or the asbestos fibres that hold is together so firmly

I can understand using polished concrete for a floor, but what is the advantage for smaller areas like counter tops and around showers? I must be easier to get a professional to knock up something from a suitable stone in his workshop.

The rates are here: http://www.icax.co.uk/Renewable_Heat_Incentive_tariff_tables.html Have you looked into becoming your own RHI/MCS installer. The company I worked for fitted a PV system to the bosses house to get accreditation. Was not that costly, and I seem to remember that the cost for an RHI cert was not too much (arond 700 quid). It was 5 years ago, so things may have changed.

That was my thinking at first, it really comes down to the design I think.

And then this: Money, get away Get a good job with good pay and you're okay Money, it's a gas Grab that cash with both hands and make a stash New car, caviar, four star daydream Think I'll buy me a football team Money, get back I'm all right Jack keep your hands off of my stack Money, it's a hit Don't give me that do goody good bullshit I'm in the high-fidelity first class traveling set And I think I need a Lear jet Money, it's a crime Share it fairly but don't take a slice of my pie Money, so they say Is the root of all evil today But if you ask for a raise it's no surprise That they're giving none away Away, away, way (Away, away, away, away) Songwriters GOAPELE K.

Mafaldina There must be a wealth of knowledge down here about sewage treatment plants as there are loads fitted. Such a shame that there is no way of easily getting the info. Ian I am sure you meant to say the air pump should be in a building, not in the house. If in the house, it will suck out the warm air (which may help digestion) and play havoc with the MVHR, I don't know much about these units (just used to see Klargesters units a lot when I lived in Aylesbury), but I suspect that there is a lot of nonsense said in the brochures. They basically work by agitating and aerating the sewage. So bubble size should not make any difference (within reason) as it is the total energy needed, not the instantaneous energy. So a simple timer is probably all you need to 'clean' each 'batch', think of it as a multiple batch process rather than a continuous process. So air volume x time is the important metric rather than bubble size, which is a proxy for surface area (small bubble, greater area, but less energy). Keeps as many things that have to be changed out of the ground (so all pumps, gears, switchgear in 'the shed). As for shape, spherical or conical, this may make a difference for smaller volumes. Just a case of knowing the sizes and volumes. A sphere will have a greater top surface area than a cone for any given height, volume or in this case, the mass of waste in it.

When you try and put a value on anything, you need to ask a few counter questions. So, taking a subject that I know about, beaches, you could ask: How much should I pay to use that beach? How much should I be paid to not have access to that beach? Would others be willing to pay more, or less, for what I currently get for free? Same with planning: If you object to a planning application, are you willing to be compensated, or even by the plot, or move out of the area. You can easily put a price on any of those. So ask yourself the counter factual, which you have done, then put a cash price on them. So say you don't know about loft conversions, but you do know what premium they can support locally. You also know how much you are willing to spend on getting a conversion. Take one from the other, then decide if it can be done within that price. That will tell you if an 'expert' is offering value. X is the unknown factor, spurt is a drip under pressure.

Yes, let your MVHR unit do the work. You do still get a 'biofilm' problem, usually called a scum line. So if you are worried about this, and the environment, then spend the money on a suitable cleaner.

I used to work for a PV installer. I really could not see the difference in modules, except for looks i.e. all black, no silver. Apart from damage, I have also not heard of a module failing. So discard the sales hype, go for the cheapest. This is also true from the different 'chemistries', there may well be a marginal improvement at certain light levels, but like a Porche on the M25, it is rare that you actually benefit from it. No matter the size, performance or price of a module, it will generate very little when it is a dark winters day.

Does SAP (TER/DER) use primary energy as a fuel source? If so, that could swing it as our electricity grid is getting less carbon intensive.

Then shop about for the HP you want, that could save you a fair bit.

Run the waste water though a W2WHP. That would cost even more.

Are you going for the RHI, that pushes the price of the install up.
