An arborist is a very special career, as it requires a detailed knowledge of all the tree types, a detailed knowledge of the operation of all the associated machinery, a detailed knowledge of all of the safety aspects and a high degree of physical fitness plus a excellent ability to get on with people and work in a close team.
Arborists are called in to deal with trees on residential and commercial properties, as well as for councils and farms and general forestry. The work maybe just trimming up trees and making them safe, or it may be pruning damaged trees after a storm, or it may be clearing a stand of trees for a commercial operator or residential homeowner. All this work requires a high degree of knowledge about individual tree types and what sort of pruning is required, and what sort of safety aspects are required.
Often tree fellers are required to remove trees that are located amongst buildings, and in this case they will have to climb the trees using safety harnesses and ropes, and then start cutting the tree in pieces from the top. To the casual observer this looks very dangerous work, and indeed it would be dangerous if the operator wasn’t experienced, but these arborists have had many years of experience and training, are very fit, and work in a very close team so that the whole project is extremely safe.
The arborist Tauranga will climb the tree using ropes and an ascender and with special spikes on their boots, and then after they have tied themselves off safely they will start trimming the tree from the top down. They have a full size chainsaw hanging from their belt plus a much smaller battery operated saw for trimming small branches, and with this equipment and their years of experience and extreme fitness they can make very short work of even the tallest tree. All that will be left after their work is a big pile of short logs and branches around the base of where the tree was.
A highly skilled digger operator will come in after the arborist has finished cutting a tree down, and will use his grabber to haul the timber and logs and branches off to the wood chipper. The casual observer will generally be amazed at the speed that the small teams can operate at, and in the matter of a couple of days an entire stand of trees can be heaped ready to be crunched up by the wood chipper. The wood chipper is a very impressive machine that is exceedingly powerful, and can demolish a very large log in seconds and pump all the chips at high speed into the tray of a large lorry. When the team finally depart the scene there should be nothing left.
Skilled tradespeople are found across all lines of business, but possibly the most productive of these trades could be those highly skilled operators of the very heavy machinery found Outdoors in the construction, roading, farming and Forestry businesses. The reason these tradesperson’s are so productive is that with their heavy machinery they can perform apparent miracles in a very short space of time if they really understand their machine and a highly skilled in the way they operate it.
Heavy machinery is by it’s very nature very expensive to purchase and expensive to operate, and skilled operators of vital if they are to work at maximum efficiency what’s the minimum amount of damage and maintenance to the machinery. For example a backhoe operator digging a large and long Trench will need to have a very fine touch if the trench is to be very accurate and it’s the operator there’s not to get stuck in difficult patches. The type of skills that are valued my company’s running these machines can take many years of Constant experience to build up.
Sometimes the achievements of the operator and the Machine can appear miraculous to the casual Observer, particularly when a skilled operator is operating a very large hymac for digging trenches, shifting Earth and rocks and rubbish, demolishing buildings and structures, and moving trees and scrub. The operator experienced in the forestry sector will achieve miracles over a few hours with their massive grabber on the end of the long hydraulic arm that can literally rip trees out of the ground and can move massive branches and logs around with ease. A skilled operator can clear a felled grove of trees and scrub with about the same amount of personal effort as a homeowner raking up the leaves off their back wall. The massive swinging rubber can appear very ungainly and uncontrollable at first but in actual fact is pretty much an extension of their own hand, but multiplied in the size of grip and the strength of left by many hundreds of times. A gripper for example can pick up a collection of massive branches and trunks up to a metal or more in diameter and weighing up to 10 tonnes, and then carefully and easily move those around and stack them or even feed them into a high powered industrial strength wood chipper.
Who scored heavy machinery operator will deeply understand how they’re machine works, what it’s weak points are but what it’s strengths are and how much work it is able to do. The operator also have learnt how to operate the machinery and such a delicate fashion that it is like operating their own hand and fingers. Very good operators of the massive Digger’s for example able to demonstrate their supreme skills by lifting and egg out of an egg cup and putting it into another egg cup without breaking the egg or the egg cup. The same digger can pick up 4 or 5 tons of rock in one bite and deposited 10 metres away.
Climate change is forcing the world to move away from fossil fuels into renewable energy. While there is obviously a lot of resistance from the fossil fuel industry, dramatic cost reductions in solar panels and installations and in wind turbines has meant that in many countries it is now cheaper to install solar or wind then it is to install a more traditional coal fired or oil or gas fired Power Station. And in most countries it is even cheaper to install solar then it is to continue burning coal in an existing coal fired Power Station. Consequently a lot of coal fired stations are closing down.
Wind and Solar Power are great Solutions except that the power supply is intermittent. Power is not generated if there is no wind or if it is night and there’s no Solar power. The solution for many countries is to use Wind and Solar Power as a replacement during the day for burning coal, and then use coal when the Wind and Solar Power is not being generated.
A brand new technology dad is coming onto the market in a big way is lithium ion battery storage on a very large scale that can be charged up during the day and then discharged overnight. There are hundreds of thousands of homeowners in North America and millions of homeowners in Europe who have solar panels and a growing number with battery storage, maybe to save power cost over the life of the installation but also to provide an emergency supply if the power goes off. There are also a number of utility scale battery storage installations dotted around the world to not only provide storage for solar power but also to store power up during the day and prevent power spikes occurring in the network.

Battery storage can be a low-cost alternative to the massive cost of upgrading an electrical power network. A very interesting feature is that the supply and installation time for the storage battery array is generally very quick, and it can be an ideal solution for emergency situations such as in South Australia.
A very recent development from Tesla is the solar roof, where the solar panel is embedded inside glass tiles that are shaped to resemble standard roofing tiles and slates. The glass tiles have micro louvres embedded in the surface so that from ground level the tile looks like a normal tile but from above the solar panel is completely visible. The glass panels are reputed to be tougher than any comparable roofing tile, and the lifetime cost including power savings is considerably less than a cost of a normal new roof.
