Football kit (American football), has changed dramatically over a relatively short history, such that early football helmets look positively medieval and the latest anti-concussion helmets are fully fledged gadgets in their own right.The first football helmet designs were soft shell lattices that resemble those still worn by rugby players. Unlike rugby, however, contact can be made when you don’t have possession of the ball, so helmets became progressively more robust and elaborate. Around the 1920s helmets were clearly inspired by Roman army ones, only made of soft leather and occasionally with full face-masks. These ‘executioner’ helmets are the most sought after collectors items, today.The first metal face masks appeared in the 30s although they did not become commonplace until the 50s, when the modern helmet took shape, eventually becoming a hard plastic or composite shell.

Today is the 50th anniversary of the launch of Sputnik, here are some of the other lesser known Soviet satellites.Soviet space gear looked different to NASA space gear. There was something alarming about this, since it meant that there was a cultural and aesthetic aspect to the type of their design that we expect to be based purely on rational criteria.These days the variety of satellite design does tend to reflect their function more than their provenance, however here are our picks of the ones that were quintessentially Soviet. Vote on your faves.

Nothing less than human made lightning. The massive fields generated by resonance between pairs of stepped up induced capacitors create potential differences greater than the resistance of air between the coil and a nearby conductor. This allows fractal currents to flow as the air itself conducts and ionizes.Although Tesla coils are largely created for fun by dedicated enthusiasts, they originally had a real purpose in mind. Tesla figured that he could create a wireless electrical grid and went as far as to build a tower on Long Island that would be its first transmitter. The idea was never realized, however in Russia really large scale wireless power networks were actually tried, as can be seen in this list.Vote for your faves.

Apple’s refresh of the Macbook line this fall is more evolutionary than revolutionary. In terms of design they have continued the trend, which started with the iPhone (see the drilled headphone jack hole on the original model) towards machining directly from block metal. This has lead to the latest Macbooks as being described as having monocoque structures, something which may not strictly be false but which is meaningless in the context.A monocoque is a single piece shell structure, it is a nice sounding word and is often used in marketing literature because it sounds technical. Because of this, and because of the fact that things like commercial airliners are hybrids of frame and shell structures almost anything can be described as such. There is a perfect geodesic truss in the list below which is described as a monocoque shell structure (the opposite), while an ordinary soda can is a monocoque. The use of machining for Apple parts has more to do with tolerances and finish and almost nothing to do with structure, so the term is not relevant.Below we discuss the merits of things which are described as monocoque – but as for the Macbook, not really

Apple monocoque or not

I’ve picked the most interesting selection I could find from the worlds largest gatherings. The largest anti war protest was in Rome in 2003, against the Iraq war, where more people gathered than for the annual pilgrimage to Mecca, the Haj. In fact, Sao Paulo’s Gay Pride festival is roughly the same size as the Haj, with 2.5 million attending in 2006 and the Haj isn’t even necessarily the largest gathering in Islam, with 14 million people attending the Shiite Arab’een in Iraq. Religious ceremonies dominate, with a Papal mass in Ireland in 1979 resulting in a third of the population (1.25M) gathering in a single field, but paling in comparison with religious gatherings in India, including the Kumbh Mela which drew an unbelievable 60-70 million people over 45 days in 2007, making it the largest gathering in history.

The legendary fleet of BBC spy vehicles. The BBC has a cosy reputation, but to people outside the UK the fact that TV owners have to pay a compulsory license fee to fund the BBC (even if they only watch other channels) seems absurd. Coupled with this, the BBC actively police whether people pay for their license and to do so they have a mythical fleet of hilariously creepy ‘TV detector vans’ that supposedly can spy on you and pinpoint exactly which room you might be watching a TV in. Whether they work, or whether they even exist or not, is open to question, these few images are the only ones we could find of them. Nevertheless, their very concept is an Orwellian nightmare.

Aside from a couple of custom versions that we couldn’t resist, the emphasis here is not on novelty but on design, since, as we believe these picks show, sidecars are a genuinely viable and interesting mode of transport.

The Apollo 12 Quarantine Airstream – which ended up on a fish farm

July 15th, 2009 #link

Vintage Airstreams are cool enough, but imagine owning a NASA moon astronaut quarantine version.

The Apollo 11 Quarantine trailer is in a museum and the never used Apollo 13 one is on board the USS Hornet, but the Apollo 12 one was sold off as surplus and ended up at a fish farm, as seen here.
An amazing find.
