Revolutionary multi-directional elevator concept (video)



Unsurprisingly, Douglas Adams suggested it first*, but ThyssenKrupp look like bringing it to fruition: elevators (lifts) that move horizontally, as well as vertically. They are able to do this because they are driven electromagnetically. Elimination of heavy cables allows multiple lift-cars to occupy the same lift-shaft at the same time & improves energy-efficiency. Other claimed benefits include less floor space occupied by lift shafts & less waiting time for passengers.

http://www.gizmag.com/thyssenkrupp-magnet-drive-elevator/34976/

Claim of, “world's first cable-free elevator”, in the article linked above ignores hydraulic lifts, such as are used in the Statue of Liberty, which recently had an oil change:

_________________
* The Restaurant at the End of the Universe, by Douglas Adams, 1980, chapter 10

“Modern elevators are strange and complex entities. The ancient electric winch and “maximum-capacity-eight-persons" jobs bear as much relation to a Sirius Cybernetics Corporation Happy Vertical People Transporter as a packet of mixed nuts does to the entire west wing of the Sirian State Mental Hospital.
“This is because they operate on the curious principle of “defocused temporal perception.” In other words they have the capacity to see dimly into the immediate future, which enables the elevator to be on the right floor to pick you up even before you knew you wanted it, thus eliminating all the tedious chatting, relaxing and making friends that people were previously forced to do while waiting for elevators.
“Not unnaturally, many elevators imbued with intelligence and precognition became terribly frustrated with the mindless business of going up and down, up and down, experimented briefly with the notion of going sideways, as a sort of existential protest, demanded participation in the decision-making process and finally took to squatting in basements sulking.

Pilots report increased near-collisions with drones


Credit: Daily Mail

Air flight is relatively safe. At least, about as safe as flying through the air at hundreds of knots, thousands of feet up, in a fragile aluminium tube, carrying many gallons of flammable fuel, with an on-board ignition sources (electronic system & engine), can be.

Actually, the most dangerous parts are taking off &, most of all, landing. Which is why most air crashes occur at airports.

See image above.

Why is aviation relatively safe?
• participants put their life on the line
• barriers to entry are high: aircraft are expensive, pilot training is both expensive & time consuming
• very tightly regulated
• if you do something wrong, sooner or later you have to come back down, at one of few landing spots, & face the music

None of the above applies to the rapidly growing drone market. Regulations are rudimentary & difficult to enforce. In the USA there is a, “not above 400 feet, not within 5 miles of an airport”, rule. It is not always observed (placing aircraft at risk when they are most vulnerable – see links below), & doesn’t apply to areas such as hospitals, where rescue helicopters have to land from time-to-time. Another at-risk area is fire-bombing sites.

Want to fund a mission to the Moon?



Want to finance a space mission? Through the wonder of crowd funding, now you can be a part of Lunar Mission One, for as little as three British pounds.

Aims:
• land near the South Pole of the Moon – not previously explored
• drill a hole at least 20 metres (up to 100 metres) deep
• recover cores for examination by on board instruments
• insert a time capsule into the hole

Part of the time capsule will be occupied by private material, submitted by funders.

An ambitious project in itself will be the remainder of the contents of the time capsule:

"a publically assembled, authoritative record of life on Earth, with a history of humankind and a species database that chronicles the Earth's known biodiversity and how it all fits together – from geology to atmosphere. This archive will be available online both during development and after the Mission has been accomplished. We will have laid the groundwork for future generations to develop and maintain this hugely valuable research and educational tool. Publically owned and accessible to all, this archive is a hugely ambitious plan that could only be resourced by a project of this scale." – Wow!

Lollipop for first gen Samsung Note & Motorola Moto G


CyanogenMod 12.0 incorporating Android 5.0 Lollipop

There is reason to think that there will be no release of Android 5.0 Lollipop for the original Samsung Note (N7000) or first gen Motorola Moto G.

http://www.techradar.com/au/news/phone-and-communications/mobile-phones/android-l-5-0-release-date-when-can-i-get-it--1257804

A problem with any hardware is that, sooner or later, support from the manufacturer comes to an end. In this case, though there is an alternative: CyanogenMod will be releasing Lollipop for first generation Note 1 & Motorola Moto G. This illustrates just two of the advantages of custom ROMs: typically sooner to release, & continue support long after the manufacturer has lost interest:

Electric vehicles have a number of advantages over those powered by internal combustion engines. For the armed services, they have some additional advantages:

• silence is an aid to covert operations
US military pays $400 per gallon for gasoline delivered, in theatre*. Electric vehicles hold the promise of reduced costs.

With this in mind, the general purpose vehicle fleet of the Los Angeles Air Force Base has been replaced with plug-in vehicles. Many of them with vehicle to grid capability.

10 questions on hydrogen fuel cell cars to ask Toyota, Honda & Hyundai

A couple of issues which are not well developed in the linked articles:

• While hydrogen can be produced by splitting water electrolytically, “… in practice, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming or partial oxidation of methane & coal gasification …”* I.e. it is not “green”.
• “The large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), package the light gas by compression or liquefaction, transfer the energy carrier to the user, plus the energy lost when it is converted to useful electricity with fuel cells, leaves around 25% for practical use.” – Dr. Ulf Bossel**

Does a feather really fall as fast as a bowling ball? Brian Cox takes a look – update

You may remember your science teacher telling you that all objects fall at the same velocity, regardless of mass. There is something counter-intuitive about this, but in practice, two rocks of different masses do fall at the same speed. What about a bowling ball & a feather? Obviously, the feather is slowed by air resistance. But what would happen if there was no air resistance?

Professor Brian Cox1 took a look:

11 reasons why the iPhone 6 Plus is better than the iPhone 6


Credit: Apple/Pocket-lint

http://www.pocket-lint.com/news/131751-11-reasons-why-the-iphone-6-plus-is-better-than-the-iphone-6

My list:

• Will it bend? – despite all the hype about bend-gate, when Consumer Reports actually did some measurements, they found that the 6 Plus is actually less bend-prone than the 6.
• More screen real estate – I've owned a succession of tablets because a 4 to 5 inch screen just isn’t big enough. 5 to 6 inch just might be.
• I have big hands – more comfortable with a bigger phone. Bigger fingers are less precise for touch screen use, so I use a stylus. For this reason, two-handed phone use is not a barrier for me. Also, on a bigger screen, all other things being equal, all of the touch-targets are bigger, so, paradoxically, I may actually be able to go to one-handed use with a bigger phone.

But … the iPhone 6 is outselling the 6 Plus 3 to 1:

Tesla Model S – tyres cost more than “fuel”


Credit: islandus.is

Electric vehicles are very cheap to run, compared with internal combustion engine (ICE) vehicles. There are many factors which operate together to make this happen: an electric motor has one moving part. An ICE has hundreds, all grinding away at one another. And the whole thing is driven by explosions! An ICE vehicle has to be serviced frequently because of the ICE itself. Explosions & hundreds of pieces grinding one another to destruction have to be cooled &/or lubricated. Oil gradually loses its ability to lubricate, largely due to contamination with fuel & combustion products. Spark plugs, fan belts, air filters, oil filters & the oil itself all need to be replaced.

Another factor is that electricity is much cheaper per kilometre than petrol or diesel, or, as one Tesla owner has found, than tyres:

Want to try the stock Android experience? Now it's easy


Credit: Google/Reddit

Want to try the stock Android experience? If you have Android 4.1 or later, you can. Just install Google Now Launcher.

Before you do that, you might like to install Home Switcher, which does pretty much what it says: allows you to easily switch the launcher you get when you press the Home button. A search for Home Switcher in the Play Store will find many matches, some with exactly that spelling. I’m using the one by “ymst”. Others may work as well, or better, but that’s the one that has done everything I’ve wanted on a Samsung Galaxy S4.

Home Switcher:
https://play.google.com/store/apps/details?id=ymst.android.homeswitcher

Google Now Launcher:
https://play.google.com/store/apps/details?id=com.google.android.launcher

When the installation has finished, click [OPEN]. Congratulations, you’re now having the stock Android experience.

http://www.forbes.com/sites/gordonkelly/2014/08/06/stock-android-on-every-device/

If you decide you don’t like it, or want to switch back temporarily, just use Home Switcher to switch back & forth.

If neither the stock launcher, nor Google Now Launcher are to your liking, try Nova Launcher. Free & paid versions, with many options to tweak, if you are so inclined.

You may remember a recent post about an upcoming survey of public electric vehicle charging facilities in Japan by Toyota & how puzzling such a survey is, when conducted by a company whose corporate attitude to electric vehicles varies between hostility & indifference.

Something the linked article doesn’t mention is the Note 4’s adaptive fast charging – zero to 50% charge in 30 minutes – only works with the supplied charger, but could be a lifesaver.

Toyota to survey electric vehicle charging facilities in Japan – updated


Credit: Charged EVs

Toyota’s effort to manufacture sustainable vehicles has, so far been restricted to the Prius hybrid. In some markets, there is a plug-in version (with a larger battery), in which petrol is augmented by electricity from the grid.

In the US, Toyota marketed a battery electric vehicle (BEV) variant of the RAV 4, with battery & drivetrain supplied by Tesla. However, this vehicle was seen as a compliance car. I.e. produced & sold in small numbers, in restricted markets, to comply with emissions rules. Toyota hasn’t renewed its contract for supply of battery & drivetrain, & has, in fact, sold its Tesla shares.

A misleading advertisement produced by Toyota’s Lexus subsidiary in the US suggests that all BEVs require 4 hours to charge at a public charging station.

Update: accuracy of Toyota anti-BEV advertisements isn't improving.

Toyota’s plan to begin marketing a hydrogen fuel cell car in the US in December, seemed to put an end to any possibility of a BEV from that company.

With an attitude to BEVs which seems to range between disinterest & hostility, Toyota’s plan to survey charging facilities in Japan is puzzling:

Voicing Darth Vader

You may be aware that the Darth Vader character in the Star Wars movies was played by English actor, David Prowse. Did you know that James Earl Jones provided the voice?

Prowse’s voice certainly doesn’t have the presence of Jones, due at least in part, to the muffling effect of the mask, perhaps also affected by Prowse’s West Country accent.



Interesting, perhaps slightly amusing, but a long way from being as hilarious as some want to suggest.

Google study finds email scams are more effective than you'd expect

There’s a widespread belief that phishing emails have a very low success rate, & depend on a huge volume at virtually zero unit cost to get a return. Don’t relax just yet, thought, because a recent co-operative study involving Google & UCSD, shows a success rate of up to 45%:

0 to 100 km/h in 1.785 seconds* & less than 30 metres (video)


Credit: AMZ Racing/Gizmag

* awaiting official ratification by the Guinness Book of World Records

Built by students from ETH Zurich & Lucerne University of Applied Sciences & Arts in Switzerland, for the Formula Student international competition. Design & construction time was less than 12 months. Total output is only 147 kW (200 hp). Available power is put to best use by:
carbon fibre construction, including monocoque chassis & wheel rims, limits mass to 168 kg (370 lb)
• hub motors drive all 4 wheels, with individual electronic traction control

Video of the 0-100 kph run:





This vehicle is so competent, none of the drama comes through in either video. Over so soon too! ;)

From the driver's seat, it must feel very different. Witness this description of 0-100 in 3.2 seconds in a McLaren F1: "It was among the most shattering few seconds of my life ... I just hung the hell on as the world melted into a smear."

Richard Branson angered by coverage of Virgin Galactic test accident


Credit: AP/BBC

Having seen the images above, the recent Virgin Galactic accident was widely interpreted as an engine explosion. However, a US National Transport Safety Board (NTSB) representative has said that premature deployment of the feather capability was the cause of the accident.

National Transport Safety Board representative explains feathering



Spaceship 2 feathering in testing



Feathering is the solution Virgin Galactic has adopted for the problem of re-entry into the Earth's atmosphere*. It was designed to be deployed at 350,000 feet. By decelerating the SpaceShip at extreme altitude, in a thin atmosphere, extreme heat build-up, as experienced by NASA & other space vehicles (with occasional catastrophic results), is avoided. Richard Branson & others have referred to this as, "carefree re-entry"**.

In the recent accident, feathering was deployed at a relatively low altitude (40,000 feet), where the atmosphere is much thicker, at a velocity greater than Mach 1. Forces generated were much greater than SpaceShip 2 would normally encounter. Apparently these forces destroyed the aircraft.

In the image at the top of this post, the right hand pane appears to show a ball of flame at the top right, with pieces of SpaceShip 2 & a debris trail below & to the left. The apparent ball of flame was widely interpreted as an explosion in progress.

In light of the NTSB investigation, the image may be interpreted as the feathered space vehicle with the rocket engine pointing straight up. I.e. away from the camera. In this case, the apparent, “ball of flame”, would be the rocket exhaust pointing straight down toward the camera.

TrackR bravo – not just another tracker for your keys (video)



There are lots of trackers out there. Attach it to keys. Link it to an app on your smartphone. When your keys go missing, locate it using the app. You can even make the tracker beep. Works the other way too. If you misplace your phone, press a button on the tracker & your phone will beep. Even if on silent.

Heard all this before.

What makes TrackR bravo different is a, “crowd GPS network”. To quote the Indiegogo page: “When another user of the TrackR app comes within 100ft range of your lost item, you will receive a GPS update of where your item is.”

So they sell a few thousand TrackR bravos world wide, that doesn’t create a very big “crowd GPS network”.

Well, it doesn’t have to, because the the “crowd GPS network” already exists:

Virgin crash sets space tourism back by years – update – no explosion


SpaceShip 2 has an engine explosion soon after being dropped from the White Knight 2 launch vehicle.
Credit: AP/BBC

Update: US National Transport Safety Board investigation has revealed the accident was caused by premature deployment of the re-entry system.

Virgin’s launch system has a “re-useable first stage” in the form of the jet-powered aircraft, White Knight 2. At 40,000 feet, SpaceShip 2, the second stage, is dropped, the pilot starts the rocket engine, & the craft continues to around 350,000 feet.

Virgin rocket motors are of a relatively new type, using rubber as fuel, with nitrous oxide as the oxidising agent. Porous rubber allows the oxidiser to diffuse through. Throttle control is obtained by varying the flow of nitrous oxide.

Rocket motors by their very nature, release huge amounts of energy in a very short period of time. By this means, they achieve amazing outcomes, such as lifting SpaceShip 2 to 350,000 feet. Sometimes the mechanisms creating, containing & directing this energy, fail. Result: an accident such as has just occurred.

And space tourism? Virgin had plans to carry it's first paying passengers into space in 2015. That schedule will have to be revised.
