How will Tesla’s Gigafactory reduce cost? — update


Chevrolet Volt battery pack uses proprietary cells
Credit: GM/Green Car Reports

Electric vehicle (EV) manufacturers use lithium iron phosphate cells, connected together to form a battery pack for electricity storage. Almost all use proprietary cells.

Almost all — Tesla is the exception, using 186501 size laptop cells. Why 18650? Because they are commodity cells. I.e. multiple large volume manufacturers world-wide, for widespread use in multiple applications (including laptops), has reduced cost by competitive, volume production.


AA cell left, 18650 cell right
Credit: Kaayee Electronics

18650 cells are cheaper than the proprietary cells used by other EV manufacturers, both individually & per kWh of capacity. But it’s not all good news: each individual cell is smaller, so more of them are required to construct a battery pack of a given capacity. Thats more wiring, & more connections, which adds to cost.

Tesla’s Gigafactory, as its name implies, will not just add a few percent to annual world production. Planned 2020 Gigafactory production will exceed 2013 global production2.

In addition to volume of production, there is reason to believe that Tesla will also force costs down by changing the volume of the cells themselves3. A slightly larger cell of 20700 size (i.e. 2 mm wider, 5 mm longer than 18650) will be 33% larger in volume4, with a similar effect on storage capacity, for negligible increase in cell cost. There has also been speculation about 26650 cells5 (8 mm wider, same length as 18650).

For a given pack capacity, using 20700 cells will yield a battery pack containing 33% fewer cells & a similar reduction in wiring & connections, further reducing cost.

In summary, pack cost is expected to be reduced by:
1. volume cell production
2. reduction in cell count & cost
3. reduced pack assembly costs
____________

1 18650 — what do those numbers mean?
Rather than continue with the multiple, chaotic naming systems used for other battery chemistries, a naming system which specifies the physical dimensions of lithium ion cells has been adopted:
first 2 digits: diameter in mm — 18 mm diameter for 18650
last 3 digits: length in tenths of a mm — 65.0 mm length for 18650
AA size in a lithium cell is 14500 — 14 mm diameter x 50.0 mm length
AAA lithium cell is 10400 — 10 mm x 40.0 mm
Length is specified to one tenth of a millimetre because it is a more critical dimension for making a good electrical contact.

Daimler SuperTruck — 115% improvement in fuel efficiency


Credit: Daimler Trucks North America/Auto Blog

Big rigs are relatively small in number, but clock up huge distances — 120,000 miles per year (193,000 km), at very high fuel consumption — 5.5 to 6.5 mpg* (US) (6.6 mpg UK, 42.8 litres/100km).

Fuel improvements in this class of vehicle can yield substantial reductions in fuel use & CO2 emisssions. Daimler Trucks North America is researching ways to make this happen, & their SuperTruck is one of the products.

Testing included highway driving in Oregon & Texas, city driving in Portland, Oregon, & laboratory tests. Between San Antonio & Dallas, at an average speed of 65 mph, with a gross weight of 65,000 pounds, the truck averaged 12.2 mpg (US) (14.7 mpg (UK), 19.3 litres/100km).

Just what have the other car manufacturers been doing all this time?


Credit: TestDriven

“In fact, it makes us wonder: just what have the other car manufacturers been doing all this time, if what amounts to an internet start-up company can suddenly come out with this.”

http://www.testdriven.co.uk/tesla-model-s-review/

The item linked above reads in part: “Let’s not get bogged down in hypothetical meta-discussions about an electric car’s green credentials, because that way lies endless debates about how its ecological aspirations extend only as far as those of the power station it’s fed by.”

That statement is misleading. No, “endless debates”, about an, “electric car’s green credentials”, are justified. The issues are actually quite simple.

Pro: Any electric vehicle (EV) driver can provide for renewable electricity for that vehicle by generating green electricity with rooftop solar or entering into one of the many, “green power”, arrangements available around the world. All EV owners I know are doing one or both of these.

Con: But the EV driver can’t be sure that, in a mixed grid (part renewable, part fossil), that the green electricity paid for, is actually going into the EV.

Pro: Who uses a particular electron doesn’t matter. What does matter is the mix of renewable verses fossil electricity on the grid. If an EV driver pays for additional renewable energy to be generated, it will displace the same amount of fossil electricity, no matter where, or by whom, it is consumed.

Pro: Electric grids around the world are becoming cleaner. Worst case, if a driver takes no steps to provide green electricity for an EV, it will become progressively cleaner, as the grid it is charged on becomes cleaner.

Flat green house gas emissions — trend or aberration?

Recently on these pages, some good news on climate change: in 2014, CO2 emissions were the same as in 2013, while the world economy grew by 3.3%.

Next question: Was 2014 the beginning of a downward trend in CO2 emissions, or merely an aberration?

Google’s 2015 Pixel — best Chromebook to date

Many people’s requirement of a computer are modest:
● email
● web surfing
● social media

This seems to be the target market for Chromebooks. Modest price matches the modest capabilities.

Then came the Google Pixel. Far from modest hardware & price, with ordinary battery life.

In its second incarnation, somewhat better price ($US999 & $US1,299), premium hardware, & battery life right up there with the best.

VW investigating 700 km electric vehicle battery

Actually, a bit more than investigate — they’ve bought a 5 percent holding in QuantumScape, the company developing the battery, with an option to buy a bigger share, after it makes a decision on the battery — “by July”.

And the battery? Its solid state, & in addition to higher capacity than other EV batteries, it’s variously described as, "fire proof", or, "fire resistant".

What Apple's website looked like in 1998


Credit: CBSNEWS

If it looks less sophisticated than you would expect from a multi-billion-dollar company, keep in mind that Apple was much smaller at that time, HTML itself was a lot less capable, most of the supporting technologies didn’t exist, & few users had the bandwidth to view anything more complex.

How to maximise your free storage space on every cloud service

Lots of free storage in the cloud from Dropbox, Google, Box & others. Once you have an account, there a few things you can do to increase storage, depending on the provider.

Another option for more storage, is to just sign up with another service. There are quite a few listed in the linked articles, & below.

https://www.lifehacker.com.au/2015/03/how-to-maximise-your-free-storage-space-on-every-cloud-service/

Something to consider before taking up time-limited storage, such as the Dropbox offer of 48GB of space for two years with a new Samsung or HTC phone. What will you do at the end of the two years? Start paying? Abandon your files?

If you want more security, a less-well-known service, called SpiderOak, may be for you:

If global warming is real, why is this (northern) winter so cold?


Credit: How Stuff Works

Weather happens over hours, days & weeks. Climate happens over years & decades. The atmosphere is a heat engine, which moves heat around the Globe. Oceans too, redistribute heat around the Earth. While some parts of the Earth are becoming hotter, others are becoming colder.

In parts of the northern hemisphere, cold weather is being experienced. Unusually hot weather is being experienced in parts of the southern hemisphere.

“Global warming” & “climate change” are terms used to summarise the ideas in the paragraphs above.

New MacBook 12”

Apple’s new MacBook (no Air, no Pro, just MacBook) has more lighter, more thinner, more smaller, plus a retina display.

● 13.1 mm (0.52”) thick
● 920 grams (1 pound)

Other features:
● edge-to-edge keyboard
● 12 inch retina screen (2304 x 1440)
● no fan
● touchpad no longer clicks — tactile feedback is generated by vibration motors & managed via a system of force sensors & software
● includes what Apple calls "Force Click" which allows the touchpad to respond to a range of pressures to, for instance, vary the speed of video

Inside
● new "butterfly mechanism" keys
● “terraced” battery allows shaping to more closely fit around the other components, saving space
● consumes 30 percent less power than previous displays
● which has facilitated the elimination of fans & longer battery life

Many things have been reduced, including weight & size. Another is the number of ports: the new MacBook has just 2:
USB C (the new, reversible standard)
● 3.5 mm audio

Apart from audio, USB C provides all i/o, including video if an external display is used, plus charging (USB C provides 100 Watts of power, up from 10 Watts available previously).

While the new MacBook is lighter & smaller, the list of things you will need to carry won't be:
● SD card reader — no SD card reader in the new MacBook
● USB C to USB 2/3 adapter
● USB C multiport adapter, when they become available

Need to carry a proprietary charger will be reduced, but not until USB C power supplies become more widely available.

Apple will sell you the adapters — not only is the laptop lighter, but your wallet too:

Solar powered round-the-world flight — update

At 07:12 Abu Dhabi time (03:12 GMT) Andre Borschberg took off on the first leg of a round-the-world flight in a solar powered plane, Solar Impulse 2. First stop Muscat, Oman, 12 hours away. The aircraft is single seat — Borschberg will be alternating pilot duties with fellow Swiss, Bertrand Piccard.



Part of the journey will be at night. Crossing the Pacific, between Nanjing (China) & Hawaii, is projected to take 120 hours (5 days) non-stop. With only one source of energy, the Sun, it is essential to store electricity in the 633 kg of lithium ion battery during the day, to power the plane at night.

Inherent in an aircraft, is another energy storage system: altitude. In addition to charging the battery, the plane will climb during daylight to around 3,000 metres (10,000 feet). At night, energy stored in the battery can be supplemented by allowing the aircraft to glide to a lower altitude. This works well in the Solar Impulse 2: it has been designed on sailplane principles & so has a glide ratio over 40 (how many metres it moves forward for each metre of altitude it loses)¹. At that glide ratio, 3,000 metres of altitude can be turned into 3,000 * 40 = 120,000 metres = 120 km (74.5 miles) of forward progress.

By contrast, a Boeing 747, with a glide ratio around 12 moves forward 3,000 * 12 = 36,000 metres = 36 km for a loss of 3,000 metres².

Update: 06 April, @solarimpulse tweeted: "#Si2's pilot climbs up to the height of Mt. Everest, 8,500 m (28,000 ft), in an unpressurized cabin!" At a glide ratio of 40, 8,500 metres = 8,500 * 40 = 340,000 metres = 340 km = 211 miles.

Like the idea of a smartwatch, but they’re too expensive?

How does $US32 sound?


Credit: Pipo

Standard smartwatch functions such as phone connectivity via Bluetooth, display of notifications, & pedometer are included.

Uniquely, a built in microphone & speaker + the ability to unclip the watch from the band combine to allow use like a conventional (though tiny) phone to answer calls without first dragging your mobile (cell) out of your pocket, or searching for it in your bag.
