Scammers – The dark side of the web!!

scammer with laptopScammers try every avenue available to obtain money from people and companies. Today we experienced the dark side of the web first hand.

In this morning’s post was a letter returned by the Royal Mail as address unknown, it was addressed to one of our customers, but obviously at an incorrect address. When my FD opened it she was stunned by the contents. It was fake letter that looked as though it was from us informing our customer that we had changed our bank details and that all future payments should go to this new account. It was even signed by someone pretending to be the company secretary.

We have obviously informed all our customers that this is a scam along with the police in both Cardiff and London who are investigating the origin. Continue reading

Solar powered aircraft ready for flight

solar power panelsHere at PRV Engineering we have always kept a keen eye on developments in the aerospace industry.

Therefore, it was with great interest when recently, we read about the first attempt to circumnavigate the globe in an aircraft powered entirely by the sun.
After 12 years of research and testing, the Swiss engineering team Solar Impulse has unveiled the craft that will undertake the mission, next year.
Having already demonstrated the ability to fly non-stop for 24 hours in their first solar powered aircraft, engineer Andre Borschberg and psychiatrist Bertrand Piccard have unveiled a second, more efficient single-seater craft that will enable them to take turns flying for up to five consecutive days and nights at a time — including flights over the Atlantic and Pacific oceans.

Tubular rail is the future?

22717803_mAlthough forms of rail transport can be traced back to 600BC when the ‘rutway’ was built to assist with transportation, it is widely accepted that railways, as we know them, have been in existence for almost 200 years.

Born of the Industrial Revolution, trains powered by locomotives were the fulfilment of the dreams of their creators.

Today’s railway system differs greatly to the days when steam trains could be seen chugging around the industrial heartland of Britain, transporting coal, iron and wood.

Further changes and development have been in the pipeline for some time, with Britain’s railways poised to undergo a major programme of development. Continue reading

Plans agreed for downdraft tower

Downdraft tower word cloudIt’s a fact that around 20% of global final energy consumption comes from renewable sources with more than 10% of all energy from traditional biomass, being used for heating.

At national level, at least 30 countries already have renewable energy contributing more than 20% of energy supply. Furthermore, national renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. Continue reading

CNC machining and the importance of avoiding overheating

Overheating is an issue within industry, not just for those workers struggling to cope with the increasing temperatures that even a British summer can bring, but for the industry’s machinery too.

Whilst the rising heat and humidity levels create physical discomfort, they represent real danger for the electronic components of machine tools, computers and other shop equipment. Overheating and humidity can cause switch contacts to become oxidized and begin arcing. It can also cause decreased insulation resistance, leading to shorts, loss of conductivity and changes in resistance. Continue reading
