SAFFRON SPICE


Saffron Crocus sativus, a King of spices, used for centuries 
in culinary dishes, also noted for it's medicinal properties.

In Art, Saffron has been utilized, for the distinctive colour
found in the stigmas growing within the flowering head.
The colour dye from Saffron, was commonly used for dyeing 
cloth, you can see from the next image, the intense 
colour from the stigmas.......... 
here is the Wiki link;http://en.wikipedia.org/wiki/Saffron


The image to the left represents 0.4g, price wise it works out to about £1 British pound per 0.1g !!!!. Making Saffron the most expensive spice, per gram.
Note; price based on supermarket prices.

Some of the oldest records of Saffron's use, date back
over 4,000 years. One record notes, that 50,000 years
ago Saffron pigment was discovered in depictions of prehistoric places, in Northwest Iran.
Closer to home (UK), Saffron Walden in Essex, was a big producer of Saffron, in the sixteenth century.
But things come and go, Saffron is no longer grown on a large scale, in Saffron Walden.

But fear not, in Caergwrle in Wales. a Saffron grower is having great success, in cultivating Saffron  Crocus sativus, see the link; http://www.britishsaffron.co.uk


Saffron used in Art may have limitations 
Here's why; if you buy any
reputable Saffron, look at the use label. It nearly always states" keep
out of direct Sunlight" or "keep in an airtight container", both drawing the conclusion, to the fact that Saffron, starts to degrade in Oxygen, so
any dye or colour derived from the Saffron, will over time change.
Colorists or pigment makers, refer to this as permanence, so it might
be a good idea not to use Saffron as a dye or pigment.

medicinal properties of Saffron are well known 

 today research indicates
Saffron may provide anti cancer properties, it's also an antioxidant.
Yet other research has evidence of protection against eye problems, macular degeneration for one, in fact it even reversed to a degree, eye disease in test patients with established eye conditions. Follow this link; http://www.news-medical.net/news/2009/05/17/Saffron-could-stopping-blindness-and-cure-eye-disease.aspx

How easy is it to grow saffron?. 
I do plan on growing my own, but there are a few things that make it more successful, the soil needs to be a neutral pH 7 and the soil needs to be very well draining, the corms need to be planted 6" deep, deeper than other varieties of crocus, and last of all they must be planted in a full Sun position. For every corm you plant, you get ten corms after four years, is that not a great return!.

UPDATE; 27/10/2014   I grew my first crop of Saffron this Year, they flowered in fits and starts
but produced what will be a flower from every bulb, next two Years
 should double the population of planted bulbs, my brother photographed the harvest;
he used a background of Autumn Blueberry leaves, to make a great photo set.

HYDROGEN ECONOMY....

Hydrogen the most abundant element in the Universe, if you could find an efficient way to 
extract it out of water, economies all across the world would benefit.
File:3D model hydrogen bonds in water.svg
1 =Hydrogen water bonds
Many people in many countries are experimenting as you read this page.
They are not exclusively main stream scientists, some are ordinary, science
interested people, but not with qualifications or degrees.
Amateurs have no preconceptions, they are not hindered by fixed ideals, so 
maybe they will stumble upon ( as do many main stream scientists ),
 new outside the box ideas. 

several methods are used to break the Hydrogen/Oxygen bonds.
Electrolysis is a good method, but...... it uses a lot of energy to break the covalent
bonds of Hydrogen H2 and Oxygen O.

 Even our DNA have bonds that use Hydrogen

A typical setup for extracting Hydrogen and Oxygen, the operating voltage should be around 1.2 volts DC. If you recombine the Oxygen with the Hydrogen you will have
a VERY volatile mixture, that is more explosive than Hydrogen alone. It can be used
in a car ( I don't endorse use in a automobile) either directly into cylinders or to fuel a fuel cell. This combined mixture is called "browns gas", in this form it should NEVER be
stored under pressure, as autoignition occurs at about 570 °C (1065 °F).

I do have a plan in the future to assist the Fuel consumption in my own car ( not on the Road )
but it can not be used in cars with computer controlled engines. Or EMS (Engine management systems). My car is very old and does not even have a exhaust catalyzer, so
It will not effect the set air/petrol mixture entering the engine.
My design is based on an multi stainless steel / Electrolytic cell, with a PWM (pulse width modulator) to drive it. See My assembled unit below. But not yet wired or tested.


I will post any test results I gain in a future post.

In the news recently is a new method of producing Hydrogen, without using Sun light/electricity or chemical additives. It would make it
more efficient (Maybe?)than current methods. It uses spherical silicon particles
in water to produce Hydrogen, the silicon is only 10 nanometers in diameter!, a human hair is approx 90,000  nanometers wide so
10 nanometers must be smoke particle size, so its going to take a fare amount of
energy to make silicon spherical's that small, but if you could produce enough
Hydrogen to self loop the process of making the spherical silicon particles, with
energy in reserve then it would be a top technology. Original story from; http://www.sciencedaily.com/releases/2013/01/130122143224.htm
So get inventing solve this problem, solve world energy needs.
