“Yes,” says Alexander Haissl of Germany's Berenberg Bank.
My take: established manufacturers will be happy to continue to make a minimal effort while Tesla works out how to make it happen. E.g. General Motors developed a T-shaped battery for the EV1 & Volt. Tesla showed them that flat, under the floor was the way to go, & they adopted that for the Bolt (along with other manufacturers).
When all of the problems are solved & what the market wants becomes clearer, established manufactures expect to be able to scale development &/or token production to take back the market. Nissan is an exception.1
Strength of this strategy is largely obvious – leverage Tesla's huge R&D effort & the the fact that Elon Musk is smarter than any of the competition’s engineers or management. (“He is by far the single smartest person that I have ever worked with … period.”)2
Perhaps their best hope is that Tesla will continue to share its technology.3,4
1 Nissan has been an exception – CEO Ghosn has been committed to EVs & developing them in-house since at least 2008:

Looks like a bunch of fun to share with your dog – which begs the question, why not just throw the ball & leave out the device? Perhaps KaWoof would be useful if the dog owner has a shoulder injury, or some other disability, that makes throwing impractical. Or is the purpose of KaWoof to let the dog play fetch without a human present?
It would be interesting to see how long (or even if) a dog (or dogs) would continue to use KaWoof with no human present.

The government-led push to modernize its telecommunications system was unprecedented, experts say – & provides a cautionary tale for others who might like to try something similar.
“Australia was the first country where a totally national plan to cover every house or business was considered,” said Rod Tucker, a University of Melbourne professor & a member of the expert panel that advised on the effort. “The fact it was a government plan didn’t necessarily make it doomed. In Australia, we have changes of governments every three years, which really works against the ability to undertake long-term planning, & the long-term rollouts of networks like this.”

EP9 from NIO
With just 7 built to-date, & 10 more planned, NIO’s EP9 is not a good fit for the description, “production car”, which some are prepared to give it. But it is road legal. From the look of it, make that, “barely road legal racer”.
One of the more interesting things about the EP9 is that, driven at competition speeds on the Nürburgring, a Tesla Model S drops into reduced power mode due to increasing battery temperature.1 A time of 6:45.90,2 suggests that the EP9 has the battery heating problem under control. Equally, a build price of $1.2 million3 (notice that’s, “build price”, not, “retail price”), suggests, “cost is no object”, is part of NIO’s solution.

Martin Eberhard & Marc Tarpenning, were the founders of the Tesla electric car company. Elon Musk came along later as an investor, flush with Paypal money.
In October 2016, the Tesla founders, spoke at Stanford University on a range of topics, including electric cars, lithium, hydrogen, energy, car-to-grid & climate change.
● Solving problems from first principles (01:42)
“Somewhere along the way, I started thinking that maybe this global warming thing was not a hoax & that maybe that the wars we were having in the Middle East were at least somehow involved in oil & decided that we needed to do something different. I did not start off as an electric car enthusiast, my interest was just simply using less energy. So I spent some time doing a real careful well to wheel energy analysis for every kind of technology I could find & built a spreadsheet that calculated the actual energy footprint & carbon footprint of every pathway I could find … & it was to both of our surprise, that the electric car pathway was not just better than the other choices that were out there, that included hydrogen & every form of petroleum & natural gas & so on, it wasn’t just better, it was dramatically better. So much better that it was stunning to us that no one else was doing it.” – Martin Eberhard
Elon Musk has spoken about the importance of approaching problems from first principles.1 In the quote above, Martin Eberhard, seems to be describing doing just that. Which begs the question: Did Elon Musk learn the importance of approaching problems from first principles from the Tesla founders?
● Tesla – naming the company (03:44)
● Why was the first product a small sports car? (30:00)
● How did they decide that Lotus would be the best source of a rolling chassis? (06:00)
● Lithium – sources, use in batteries, & recycling (16:25)
● Hydrogen fuel cells (22:00)
“Hydrogen is not a fuel … to make elemental hydrogen, to make H2, you have to put energy in. … the efficiency of that, if I’m using the very best technology available today, is in the order of 20-22% efficient. Compare that to a lithium battery which runs in the order of 95% efficient. It’s just not worth it. The hydrogen fuel cell car will require ... 3 to 4 times as much of whatever your source fuel is …”2,3,4
● Vehicle-to-grid (40:50)
“There’s this whole concept of vehicle to grid storage. The idea is the vehicle could draw off the grid & put energy back on the grid. … There’s two troubles with that: one is that every cycle through your battery has some cost – it’s not zero. ... Second thing is that when you’re putting energy on to the grid, (as for example, does the inverter on your solar panel), it puts some pretty heavy-duty regulatory burden on the design ... of the car – it adds some non-trivial cost to the cost of the car.”
“But, there’s another thing to think about: & that is that you can get about 90% of that value, not by allowing the vehicle to put energy onto the grid, but rather, just allowing the grid to have precise control over the charging of the vehicle. So that it can say stop & start or stop & start at this level in real time, OK? And what happens then if you have a large number of vehicles that are plugged in just statistically speaking is that all these electric cars can be used as grid regulation, & they can allow the power company to have a much much smaller amount of what’s called spinning reserve. That’s to say, generating capability that’s not being used. ... So that for example, when a big cloud passes over the giant solar panel array in the Mojave Desert, the grid then tells a whole lot of cars to, ‘Hey stop now,’ & they get off the grid, & when the wind starts honking on Altamont Pass, they can tell a bunch of cars to, ‘Hey start charging now.’ And you get about something like 90% of the value of the vehicle to grid idea, without actually taking energy out of the vehicles.”
● Electric cars will become cheaper than internal combustion engine cars (46:12)
“I’ve been looking closely at the cost of batteries recently, & it’s my belief that the cost of making an electric car will match the cost of making an equivalent gasoline powered car, probably in 2020 or 2022 – it’s coming up pretty fast.”
● Battery swapping (52:19)
“The reason that you would want to do that is because the batteries don’t have enough range, & the reason they don’t have enough range, is basically because they’re too expensive. … And so what you’re doing in a world of battery swapping is you’re taking the most expensive part of the car & you’re making it more expensive because I’ve got to have to have 20-30% more batteries around than I have cars, so I can swap them in.”
● Adapting to climate change (1:09:50)
“Quote from ... some science fiction writer: ‘The future is here now, it’s just not evenly distributed.’ … that is in many ways true, like we know how to do this. We know how to have a really advanced society that is carbon neutral. It’s just hard & it’s only in a few places … it is possible. So, I figure ... we’re gonna have to adapt to the climate change – that train has left – the CO2 is there.”

Teaser image of the forthcoming Tesla semi-truck
Credit: Tesla/TED/Tech Republic
Recently, Elon Musk appeared on TED Talks – a few highlights:
● Add one more problem to the list of shortcomings of the internal combustion engine (ICE) – it makes tunnels more expensive – cost of tunnelling is proportional to the cross sectional area of the tunnel – tunnels need to be 26-28 feet (7.9-8.5 metres) to allow (amongst other things) for ventilation to cope with the poisonous gasses ICEs emit.
● Semi – load-capacity, range, torque (19:48)
“So this is a heavy duty, long range, semi-truck. So it’s like the highest weight capability & with long range ... out-torque any diesel semi & if you had a tug-of-war competition, the Tesla semi will tug the diesel semi uphill.”
● Semi – driving experience (21:40)
“I mean it’s quite bizarre test driving. You know, when I was driving the test prototype for the first truck, it’s really weird because you’re driving around & you’re just you’re so nimble & you’re in this giant truck.” – no doubt, at least in part, due to the low centre of gravity which electric drive makes possible
● Interplanetary Transport System (32:00)
“This configuration is about four times the thrust of the Saturn V moon rocket ... This thing can take a fully loaded 747 with maximum fuel, maximum passengers, maximum cargo on the 747. This can take it as cargo.”

HitchHiker’s Guide 2 Tech has been published for a little over 6 years (first, 16 March 2011). Since that date, at least one item has been published every day – holidays, weekends, significant family & life events. In total, over 8,000 posts have attracted over 115,000 page views – even deducting a generous allowance of 56,000 page views to account for spamming from known sources.
At the moment I have a major project in train which has to be completed in a little over 60 days. As you may imagine, HitchHiker’s Guide 2 Tech consumes a substantial amount of time, which is interfering with the completion of the major project. Thus, it is with some reluctance that I will be ceasing publication on these pages with this post.
After completion of the project, time may become available again.
In the interim, I may find time to make occasional posts which will consist simply of a heading & a link to a particularly interesting article.

467 robots are being installed at the Tesla Fremont factory prior to the start of Model 3 production.
Tesla’s Model S is a luxury sporting sedan – the Model 3 is a, “mass market”, car. To appeal to a mass market, the price has to come down – “$35,000 before incentives”,1,2 has been promised repeatedly, for the US market.
Make it smaller, make it out of steel
● Most obviously, reduce cost by decreasing size by 20% compared to the Model S.3
● Extensive use of steel, rather than the more expensive aluminium widely used in the Model S.4
Reduce battery pack cost
An electric motor is simpler & cheaper than an a comparable internal combustion engine – electric cars are more expensive largley because of battery cost. A $35,000 Model 3 will require a substantial reduction in battery pack cost. This will be achieved by:
● Battery costs have been coming down world-wide for some time – including 80% in six years.5
● Price will be driven down further by increased volume – i.e. Gigafactory.6
● Reduce cell count – Tesla has historically used commodity 28650 size lithium ion cells. Individual cells in the Model 3, will be 47% larger in volume, with a similar effect on storage capacity, for negligible increase in cell cost.7
● Each cell stores more power, so fewer are needed for a given pack capacity.7
● Assembling fewer cells to make a pack is faster & cheaper.7
● Smaller battery pack – two options, the larger of which will be, at most, the same size as the smallest currently available in the Model S – “The shorter wheelbase only allows for a 75 kWh pack in Model 3 at current cell/module energy densities.” – Elon Musk, Twitter8,9
Automate the production line
● 467 robots are being installed at the Tesla Fremont factory prior to the start of Model 3 production.10
● Level of automation will increase over time, with no people on the production line itself, “in a few more years”.10
● Increased automation is planned to ultimately yield a 20 times increase in production line speed, further reducing production cost.10
Simplify the production line initially
● Initially, the production line will be simplified by producing only rear wheel drive cars. First 4WD, “probably in 6 to 9 months.”9
Streamline the delivery process
● “We need to deliver three or four times as many cars. But we don’t want to have three or four times as many delivery centers.” – Elon Musk11
● “Less paperwork, less bureaucracy.”11
● Shorten the hand-over to customers: “... get people ready ahead of time with really well-produced instruction videos.”11__________

Hoverboard was a no-show in Back to the Future year.1 We’ve been waiting even longer for the flying car, but Uber has promised them for 2020.
As you’ve no doubt noticed, the problem is that the technology doesn’t exist. Uber’s way around this is something like an X-prize – competitive development of a device to carry out a defined task – in this case, a flying car. And the prize? Access to Uber’s world-wide client-base. Though, at this point only Dallas-Fort Worth & Dubai have indicated an interest.
Uber has signed deals with five companies – if they don’t deliver, an obvious contender would be the Lilium jet electric aircraft.2

Some details of the, “flying car”, backed by Google co-founder Larry Page, have finally surfaced.
Available specs are thin on the ground:
● weighs 220 lbs (100 kg)
● single passenger
● altitude 15 feet (4.6 metres)
● 8 electric motors drive downward-facing propellers
Kitty Hawk claims that it is possible to learn to pilot the Flyer in minutes, & that it qualifies as an ultra light, so that no licence is required.
Consumer version is promised for the end of 2017.
Trusted Reviews – “Forget self-driving cars, the Kitty Hawk Flyer is officially off the ground”
The Verge – “This is the first footage of Larry Page’s ‘flying car’”
If the name rings a bell, Wright Flyer was the name of the first heavier-than-air machine flown by the Wright Brothers at Kitty Hawk in 1903.1

Although the Lilium aircraft is called, a “jet”, it would be more usual to describe its propulsion as, “ducted fan”.1
Advantages of ducted fans compared to conventional propellers1
● more, shorter blades allow higher speed of rotation & more thrust, without the problems caused by the tips of the blades approaching the speed of sound● reduced noise – especially when driven by an almost-silent electric motor
● surrounding shroud makes ducted fan safer
● occupies less space
In urban environments, where Lilium sees many of it's aircraft operating, these advantages are particularly valuable.
Conventional aircraft generate lift by using relatively few engines to produce thrust (jet &/or propeller) to drive the aircraft forward. Forward speed produces lift due to the motion of the wings through the air.2
A small number of engines is a limitation imposed by internal combustion engines. In an electric aircraft, many small motors can be used.2 Illustrations show the Lilium with 36. Many motors allow lift to be generated at low aircraft speed (even zero) because they can drive air over the wings at a speed independent of the aircraft’s forward motion.
Update – Other advantages of multiple engines include:2
● shorter (front-to-back & side-to-side) wing is lighter & generates less drag
● wings can be optimised for cruise, rather than take off & landing, improving overall efficiency
In an aircraft with few engines, the most difficult & dangerous parts of a flight are taking off & landing, due to the direct dependance of lift on speed. Wings are optimised for these purposes.
Multiple motors, by disconnecting lift & speed, increase safety at take off & landing. Wings can be optimised for cruise, increasing overall efficiency – wings are shorter & narrower & so lighter, with less drag. Check the image above & the video.
Such a configuration will have disastrous glide characteristics. Electric motors are very reliable, & 36 of them provide plenty of redundancy, but battery failure is a problem which does not appear to have been addressed. This is not surprising in a prototype with only one unmanned test flight to its credit. Two solutions which spring to mind are battery redundancy (which may already have been allowed for in the existing battery configuration) or a Cirrus Airframe Parachute System.3
Lilium has its ducted fans pivoted vertically, to direct thrust at a range of angles, including straight down, for vertical take off.
Multiple motors can be run at different speeds to turn the aircraft, eliminating the drag created by a vertical tail.
Drag is further reduced by a lifting body design4 – the body of the aircraft is shaped to produce lift – thus the wings can be smaller & lighter for the same total lift.
Lilium has backing from the European Space Agency.

Futurism – “A Real Life, All-Electric Flying Car Just Took Off”

1 Just to complicate things, almost all current jets are of the turbofan type, which is a ducted fan, where the fan is driven by a gas turbine – that is to say, a jet engine.
Wikipedia: “Ducted fan”, https://en.wikipedia.org/wiki/Ducted_fan
“The most common ducted fan arrangement used in full-sized aircraft is a turbofan engine, where the power to turn the fan is provided by a gas turbine. Turbofan engines are used on nearly all airliners, fighters, & bombers.”

Bright, shiny new mobile phone – but what to do with the old one? Some people have a drawer full of them. Two of the more popular options are: sell it, or pass it on to a family member or friend. These are obviously good options, depending on your circumstances, but there are others.
Keep it as a spare – that bright, shiny new phone, may suffer a misadventure – drop, or other physical damage, internal failure, loss or theft. In any of these circumstances, another phone to swap the SIM into, or a new SIM, depending on the misadventure, could be very useful.
Second phone – many have abandoned their fixed phone. A second phone with its own account can become a home phone. Some mobile phone providers have pay-as-you-go accounts, with no cost while the phone remains unused. I used such an account with an old phone, for several years, to contact family members at home, at no cost.
Use it as a mobile router – free public WiFi, is not always available when you need it, & is not secure1 – your own mobile data is a more flexible & secure choice. You can use the hotspot function of your mobile phone, or, if your data allocation is insufficient, an additional, data only account. Rather than buying a purpose-built mobile router,2 use your old phone at no cost.
Other possibilities include:
● add it to a multi-camera video shoot
● baby monitor
● video doorbell
● GoPro replacement
● dedicated VR headset
● white noise generator
