Solar Roof

 

 

Sunlight is energy and it is for free!

Good news for those who have been eyeing Tesla’s new Solar Roof – the company just announced pricing for its photovoltaic tiles, and they come in at just $21.85 per square foot. That, they claim is nearly 20 percent cheaper than a normal roof once you factor in the energy savings and tax credits.  Well, almost there – do it without tax credits and then we are there but OK for tax credits to get started.

At least, someone has finally grasped that making a conventional tiled roof, and then retro-fitting solar panels is little short of insane suicide.  We have the technology to make a roof out of solar panels and we should never, from this day on, ever make another conventional roof.

National Debt bigger than education Budget!

The national debt (what successive government have borrowed to buy our votes) is now £1.8 trillion.  The interest, we heard on the BBC News this evening (4th Oct 18) is greater than the entire education budget. That is insane. The people we borrow off (Chinese, Arab countries, etc) ) will not kill us off completely, they will almost do that but not quite, just milk us forever.  That is the nature of debt. We need to balance the books.  The only thing big enough is shale gas. Stop importing energy when we are sitting on a vast reservoir.  by the way, we can do it safely.

The Soil Rumen and Ion Exchange

The soil is much as the cow’s rumen. It is not the cow that digests the food, it is the rumen micro-organisms. then the micro-organisms feed the cow.

Think of the soil much as a cow’s rumen. Click on the blue band above here on “articles” and go to no 16 and click.

Zero till – less cost, more yield

Zero till with a Moore Unidrill; note the independent discs and seed coulters (right) and press wheels on the rear (left) giving even depth of placement and good seed-soil contact. (Photo courtesy Agri-Linc.)

Direct drilling comes in two guises; drilling after a little cultivation (“min till” really), and what in the USA would be called “zero till”.  Each has its own consequence in terms of weed control. Maybe I learned, years ago, most from a farms manager called Richard Noyce, he always had clean bottoms to his crops simply because, after harvest, he cultivated the surface several times to get weeds seeds to germinate, before putting the next crop in. The alternative of one pass to put the crop in does imply more work to do with selective herbicide – but that is probably going to happen anyway, so it is not an extra cost. Generally, in the hands of a sensitive husbandry man, zero till costs less and gives higher yields.

Good husbandry and using the right machinery is aiming at even depth of placement, good seed-soil contact, giving even emergence.

drought and crop yields

A lot of this, this year. Yields down too. It is largely avoidable.

A sandy soil will hold about its own weight in water.  A clay 2 or 3 times. A typical natural peat around 16 times!

A compost made from urban green waste will hold up to 10 times its own weight in water, maybe only 5 times if it is made from woody cuttings in winter (and it would have less N).  However, compost made from urban green waste plus industrial wastes will (depending on the wastes used) hold 8 to 14 times its own weight in water and possibly a lot more NPK.  Although the Environment Agency will restrict quantities, the truth is that the Fens, when Vermuyden drained them some 300 years ago, were up to 40 foot deep of almost pure compost. (Organic soils do not leak excessive N.)  It is also true that high organic, well-composted soils, can halve cultivation energy inputs and reduce chemical spraying.

So, there really should be a national policy of maximizing urban waste recycling to urban farm land. Suggest get a copy of “Survival”, read it and send a copy to your MP.

Shale gas and the NHS

This can pay for more of ………….

……. this. (and in-patients, too!)

Cut the discussion and get down to the raw facts.  The NHS certainly has its faults and can be improved without the addition of cash BUT the NHS and the social services which can take people out of hospital beds for care after treatment ARE short of cash.  The NHS really is a national gem and needs significant and on-going extra cash.  If we want it to care for us, we have to care or it.

It does not have to be supported by extra taxes.  We are sitting on enormous energy reserves of shale gas.  We are importing shale gas in specially made ships from the USA and Arab countries. We are importing natural gas from Russia which owns part of Centrica which, of course, owns British Gas. THIS IS INSANE. The UK has the best shale gas technology in the world and, yes, we can do it safely. In terms of environmental balance, it is better to do shale gas here in the UK and use the revenues to build the NHS and develop renewable energy sources.

Synthetic N Fertiliser

In the UK , around 80 % of the cultivation energy we use is to undo previous traffic compaction and around 50 % of the energy we use to manufacture and spread fertiliser goes into the groundwater. This is neither profitable in the short run nor sustainable in the long.

The nature of the Nitrogen molecule carrier/store dramatically affects not only N fertiliser losses to groundwater, but how it gets into the plant and promotes growth.

Nitrogen fertiliser can be applied in two forms; as soluble in water (such as ammonium nitrate) and as organically bound N (as part of long, Carbon-chain molecules).If the molecule is relatively small and in-organic (mot part of a Carbon chain molecule), then it can be absorbed across the root-hair wall and progressively built up by the plant metabolism into amino acids and plant proteins. This route has served us well and saved countless billions from starving and postponed their death.

There is a problem.  While “artificial” or “synthetic” fertiliser N certainly has its place, the energy cost of manufacture and the losses to groundwater are unsustainable. The alternative will be discussed in the next post on this blog.
