Comment: Good Job Tesla - Now how about that GPL source? (Score 1) 211

This is a great move by Tesla and I hope that more companies follow suit.

Now - how about releasing the source code to owners for GPL software and derivatives you ship in your vehicles?

So far I am not aware of any owners who have been successful in getting access to that code.

That's a good point, it could help plug-in hybrids, or even regular hybrids.

But given that it's not very energy dense and other chemistries, what would you rather have? A battery that starts out with 25-50% more energy density and degrades 20-30% over the life of the car, or a battery that starts out with less but only loses a couple percent? I'd personally have the battery that starts out with more energy density even if at the end of life the density is similar.

Long lasting batteries are great but not as important as lower cost and higher capacity to weight ratio...

Exactly. The energy density of these cells are very average at best.

It's nice that they last a long time as that makes them very useful for certain applications, but for EVs that's not the major issue preventing EVs from being more appealing. The major issue is energy density and cost.

Extreme durability might help with the cost aspect as batteries would hold more value for re-use after a car is otherwise useless, but it would be for other applications such as perhaps grid-storage where having batteries that basically last forever would be very useful.

The BIG issue is that the battery would not use an expensive, scarce metal: Lithium. The fact that the author doesn't mention that indicates he understands extremely little.

But Lithium is not expensive or scarce relative to current costs of lithium battery manufacture. Other metals and manufacturing costs dominate the current cost of lithium cells.

PR like this claiming the next breakthrough in batteries has been coming out for years, but what actually makes it to production are basically minor tweaks to existing chemistry.

Inevitably what happens is something keeps the technology from being mass produced, or is too expensive, or simply does not function as advertised.

I hope I'm wrong, but I'm not holding my breath.

Uh, you were the one who was comparing the i3 to the Model S.

Regardless of the cars being in different classes, you still see people comparing all types electrified vehicles against each other.

I know a LOT of Nissan LEAF owners who sold their LEAFs for a Model S, for example. The LEAF is a class down for the i3 (so even further away from the Model S), yet there you go.

I have a LEAF and have considered the same thing, but just can't justify the luxury car price tag and just don't need the extra range all that often.

You should just use the EPA numbers which measure energy from the wall. Many people suspect that the major difference in efficiency between the 60 and 85 kWh Model S were the tires/wheels used for testing - the 60 kWh Model S is lighter, but no-one except Tesla seems to know by how much.

Model S 85 kWh: 38 kWh / 100 mi or 2.60 mi / kWh
Model S 60 kWh: 35 kWh / 100 mi or 2.85 mi / kWh
BMW i3: 27 kWh / 100 mi or 3.7 mi / kWh
Nissan LEAF: 30 kWh / 100 mi or 3.3 mi / kWh
Spark EV: 28 kWh / 100 mi or 3.57 mi / kWh

The i3 is about 30% more efficient than the Model S - very impressive! On the city cycle, it's 50% more efficient! I imagine if the i3 were a lower and longer car (and thus more aerodynamic) it'd do even better on the highway cycle.

There is this stupid tendency here on slashdot to dismiss partial solutions to any problem as unworkable. Solar does not have to supply all our energy needs to still be a good idea. The economics of it still need to make sense but there is no principled reason why it should not be a significant part of the energy supply equation.

Not just slashdot, it happens everywhere.

There's a lot of GPL software in Ubuntu, starting with the Linux kernel. Does Tesla distribute the source code to Model S owners that ask?

I am not aware, yet. Have only see one owner be vocal in the past about trying to get it, but haven't . A few relevant threads. Lots of noise and general ignorance about Copyright in there, so prepare yourself.

Anyone want to get the source code for the Linux (etc.) in your car?

Actually, what's more likely is that they saw his post on the Tesla Motors Club forum detailing what he'd done and then connect the dots between the forum post and ownership data:

Tesla has been known to connect forum users to actual owners and proactively contact the owners via phone when they report problems with their car there.

Even with built-in battery or UPS, while that reduces the risk of unexpected power loss, in my experience it still happens.

As far as comparing reliability of SSDs to HDDs, an actual study found that SSDs were much more likely to lose lots of data, sometimes bricking the entire drive.

Enterprise HDDs were the most reliable, even the best SSD they tested was not as good (though similar to consumer grade HDD).

Unfortunately, the study does not reveal which drives were tested.
