The use of the sun as a power source dates back to ancient times and has been used by cultures all over the world ever since. The history of solar power begins when the earliest use of solar power was to warm dwellings by building them into the side of hills where the sun could warm them during the day. This heat would then be released all evening to keep the dwellings warm. This form of passive solar heating is still in use today with minor improvements through the years as it has been adapted for modern residential homes. The Romans were so serious about the harnessing and use of solar power that they constructed large buildings with southern facing windows to capture the heat from the sun. The water used in their bathhouses was also heated by the sun and they designed elaborate collectors to capture this heat to warm the water with solar power. These early societies even passed laws guaranteeing certain solar rights to ensure a homes clear access to this essential solar resource.

Solar Technology goes Commercial

These crude collection schemes were later refined in the mid 1700's by a Swiss inventor named Horace de Saussure who invented the first commercial solar collector. He called it a hotbox and it was used to cook food using nothing but sunlight for fuel. Many of the techniques pioneered as part of this invention are still being used today in modern solar water heating systems. In fact the first commercial solar water heater was produced in 1891 by an inventor named Clarence Kemp that was based on some of the same principles used in this original hotbox.

Solar Goes Electric

This brief history of solar power continues with the discovery of the photovoltaic effect in 1839 by Edmond Becquerel. He noticed that certain materials will produce a small electrical current when exposed to sunlight. This single discovery gave birth to the modern PV technology used in home solar power systems available today. Even though this initial discovery was little more than a scientific exhibition Cheap Women's Nike Vapormax Flyknit Violet Dust Shoes Sale , the concepts he discovered have been improved and refined throughout solar power history to allow these PV home solar power systems to provide a good deal of free power from sunlight.

The Introduction of Silicon Materials

This chapter in solar power history got another significant boost when an American inventor named Charles Fritts made the first solar cells out of silicon wafers instead of selenium in 1883. This single discovery in solar power history made these home solar power systems more efficient and affordable than ever. This was also a historic event in the history of solar power because the older solar cells made of selenium were not safe for commercial production with the manufacturing techniques available at the time.

Growing Silicon Crystals

The development of the silicon crystal line of solar cells continued until a Polish scientist named Jan Czochralski developed a technique in 1918 for growing single crystal silicon. This is far superior to older types of silicon and is several times more efficient than anything that had been available up until this point. This one single event made solar power for homes a reality by allowing modern solar panels to generate a large amount of power from simple sunlight. Modern solar cells are created in much the same way today and through the addition of other doping agents have increased their efficiency several time that of these earlier models.

Whilst you may not wish to think about premature death right now, I do think it's a responsible person who leaves their affairs in an orderly manner as possible so that their next of kin Cheap Nike Air VaporMax Plus Men's White Green , who have the pain and grief to deal with, do not have to deal with a financial mess Cheap Nike Air VaporMax Plus Smokey Mauve Men's Bordeaux Black , especially where the person was the one in charge of running the finances in the household.


So, in an attempt to make this piece more upbeat and less morbid Cheap Nike Air VaporMax Plus String Men's Black Brown , let's look at the 7 'must do' steps you can take to relieve the pressure on your loved ones.


1. Create an information document that includes:


- The name of the professional people to contact in the first instance (this could be your financial adviser planner or accountant solicitor)


- Location of where all your financial documents are held, with an overview of the amounts held in life insurance Cheap Nike Air VaporMax Flyknit Utility Men's Racer Blue Blue , savings, investments and pensions (may be in a filing cabinet or all scanned to PC)


- The action that should be taken with certain policies Cheap Nike VaporMax Moc Flyknit Triple Black Women's , eg cancelling income protection and claiming on life insurance pension funds


- Details of what your wishes are, but hopefully this will have been discussed already! (eg paying off the mortgage Cheap Nike Air Vapormax Flyknit KPU Red Black Men's , investing life insurance lump sums)


- Details of all email accounts with their log in details


- Details of any recurring payments that are being made via Standing Order or credit cards


- The location of all your online passwords. These days many of us use online password managers which store all the passwords in one place (a master password is required to gain access). Make sure the master password is stored in a different location! The service I use is Roboform.


- Details of any bank accounts held in your sole name Details of all online profiles to cancel and perhaps update initially abo.
