Old & Obsolete Technology

Post by Yuli Ban »

This thread's for discussing old forms of technology of times long past. Things that used to be cutting edge and the new hotness, the sign of the Future™ in the past, and things obsolete from the word 'Go.'

And remember my friend, future events such as these will affect you in the future

Halogen lightbulb sales to be banned in UK under climate change plans

10 hours ago

Sales of halogen lightbulbs are to be banned in the UK from September, with fluorescent lights to follow, under government climate change plans.

The move will cut 1.26 million tonnes of carbon emissions a year and deliver consumers savings, officials say.

The UK began phasing out the sale of higher-energy halogen lightbulbs in 2018 under EU-wide rules.

Now retailers will no longer be able to sell most remaining halogen bulbs, such as kitchen spotlights.

Legislation for the plans is being brought forward this month by the government.

The plan will help continue the shift to low-energy LED lightbulbs, which account for about two-thirds of lights now sold in Britain.

It is expected to mean LEDs will account for 85% of all bulbs sold by 2030, officials said.

We sell these bulbs at my work, it would be interesting to see what they replace them with?

A point made in this article concerns how the subject vessels were displaced by other better designs, but how this type of vessel did serve as a prototype of sorts for things to come.

The Soviet-Era Hurricane High-Speed Missile Boat Had Absolutely Gargantuan Hydrofoils
June 12, 2021

https://www.thedrive.com/the-war-zone/4 ... hydrofoils

Introduction:
(The Drive) Known in the Soviet Union as the Project 1240 Uragan, meaning hurricane, and given the Western codename Sarancha class, only one example of this hydrofoil missile boat was ever built, but it certainly packed a punch and was in many ways a remarkable design from a technical point of view. With enormous hydrofoil surfaces on either side at the front, and another at the rear mounting propellers, the Uragan could race across the surface of the water at an impressive 60-plus knots.

The torpedo attack craft of the early Cold War years had been supplemented by coastal craft armed with anti-ship missiles by the 1960s, with the Soviet Union pioneering much of this effort. It was Soviet-made Komar class missile boats that sank the Israeli destroyer Eilat in 1967, bringing these types of high-speed attack craft to greater prominence.

In a quest to further increase the performance of missile craft, work began on mating anti-ship missiles with hydrofoil designs, the hulls of which lift out of the water as they increase speed, decreasing drag as they are carried on wing-like surfaces. As well as boosting speed, it also typically improves fuel economy and can improve stability, even in rougher sea states. During the Cold War, the concept was not always a total success, but it certainly produced some interesting designs along the way.

Enter the Uragan, constructed in Leningrad and immediately identified by the sheer size of its titanium-alloy hydrofoils. Those at the front were of the surface-piercing type, which meant they were partly out of the water when foilborne. When not deployed, they projected well clear of the hull at an angle of almost 45 degrees.

The hydrofoil at the rear was of a different type, being fully submerged when foilborne, with vertical struts mounting rudders, plus propulsion pods at the tips. Propulsion came from a pair of gas turbines each developing up to 18,000 horsepower. Reportedly, these were maritime versions of the turboprops that power the Tu-95 Bear strategic bomber, versions of which remain in service today.

Sainsbury's stops selling CDs and DVDs

13 hours ago

Supermarket giant Sainsbury's says it has decided to stop selling CDs and DVDs as streaming services take their toll on sales of the products.

A spokesperson said Sainsbury's customers increasingly went for music and films online instead of buying the shiny silver discs.

The firm said sales were being phased out, although it would continue to sell vinyl records in some stores.

CD sales have shrunk in the past decade but were still worth £115m last year.

Other big supermarkets show no sign of following Sainsbury's lead, with larger branches of Tesco, Asda and Morrisons still stocking a range of CDs and DVDs.

Highly polluting leaded petrol now eradicated from the world, says UN

8 hours ago

There is now no country in the world that uses leaded petrol for cars and lorries, the UN Environment Programme has announced.

The toxic fuel has contaminated air, soil and water for almost a century.

It can cause heart disease, cancer and stroke, and has been linked to problems with brain development in children.

Most high-income countries had banned the fuel by the 1980s, but it was only in July that Algeria - the last country still to use leaded petrol - ran out.

UN Secretary-General António Guterres called the eradication of leaded petrol an "international success story".

"Ending the use of leaded petrol will prevent more than one million premature deaths each year from heart disease, strokes and cancer, and it will protect children whose IQs are damaged by exposure to lead," he said.

Lead started being added to petrol in the early 1920s in order to improve engine performance.
