Wait But Why

I haven’t posted an external link in a while but this is a great recent find I wanted to share: Wait But Why.  Tim Urban puts together some really brilliant, fascinating and in-depth posts about a myriad of topics.  I stumbled on it by way of his amusing post about his unexpected call from (and subsequent visit/tour/lunch with) Elon Musk (“The World’s Raddest Man“).  I later found myself up late, still caught up in his fascinating, two-part exploration of the current state (and potential, future existential threat) of artificial intelligence.

There’s an archive of posts to explore and upon subscribing for updates, you’ll receive an enticing list of popular articles to sink your time into, including these on “Science, Philosophy, Space and Anything Mind-Blowing”:

The Fermi Paradox – “The mind-twisting discussion of whether alien life exists and why we’ve never seen evidence of any. The post I get the second-most emails about.”

The AI Revolution – “A long, two-part post that took me six weeks to do—a full overview of what everyone’s been talking about with AI and the reasons I believe this is the most important topic in the world right now.”

Putting Time in Perspective – “An infographic that starts with today and works its way backwards, in increasingly large time increments, all the way to the Big Bang. Good way to put all of history in perspective.”

Brought Home a Tesla!

Okay, well… half a Tesla.  ;-)  Tesla Motors supplies the battery and drivetrain for this vehicle, Toyota’s second generation RAV4 EV.

Hey, but it’s shiny!  And fast!  And it goes much further on a charge than my 2011 Nissan LEAF:  folks say they get 120+ miles even at highway speeds.  This will be much more convenient since I currently give up half my range in my LEAF whenever I want to make a round trip over the hill from Santa Cruz.  And it has a 10 kW charger on board as compared to my old LEAF’s 3.3 kW (or 6.6 kW in 2013 or newer LEAFs).  Unfortunately Toyota chose not to include support for any DC fast charging.


Update after a couple of days:  Yup, it does 120 miles easily!  It’s great to drive the 40 miles to Palo Alto from Santa Cruz at normal highway speeds of 65-70 mph, picking up friends along the way, and find you still have 80+ miles of charge left!  Particularly when you see that the charge stations in downtown Palo Alto are all occupied anyway! ;-)

Or, as another example one month later, to drive the 95 miles to Fairfax at 70-75 mph (two passengers, two bikes and gear on board) and have 25+ miles of margin leftover.  Then plug in at a public charge station while out for a mountain bike ride and a meal and be fully charged for the return trip.  And using the heater all the way back seemed to only affect the range by about 10% – still plenty of charge leftover after getting home.  It’s so sweet to be able to easily make a 190 mile day trip without needing to burn any gas!  Looking forward to the clearer air as these gradually supplant most of those silly, old-fashioned internal combustion engines!

This second generation Toyota RAV4 EV has an MSRP of about $50,000 before rebates.  However, Toyota has been offering large cash back deals over the year from between $10,000-14,000 off the list price (purchase vs. lease), then you also get $2500 back from California as part of their program to encourage EV adoption and, lastly, up to $7500 off your Federal taxes if you purchase.  (Update: As of Feb 2014, it’s $16,500 off with an essentially interest-free lease.)

All this brings the cost down to the mid-30’s before taxes – cheap compared to Tesla Model S, but still expensive compared to Nissan LEAF. But when you also take into account that there is no gas to buy or oil changes or regular engine maintenance, any pure EV becomes even more enticing.  Driving around without ever needing to burn gas and on power generated or offset by your own solar panels is a lot of fun!  Of course, the LEAF has all these EV advantages too and it is both a much more affordable and a more efficient vehicle.

As for the Tesla Model S, it is a beautiful car but it’s way too big for my tastes.  Ideally, I’d like a reasonably-sized, sport-performance, four door hatchback with AWD (for traveling in the Sierra winter).  Something like my old Audi A3, but all electric!  (And maybe a little bigger.) The LEAF is a good size and is fun to drive (all electric torque!) but this RAV4 will let me go further (and faster) while I wait for something more ideal.  But yes, this does mean I will be selling my cute little red LEAF…  awww….

My 240V Nissan LEAF charge cord (upgraded by EVSEUpgrade) isn’t compatible with the RAV4 (there is a known compatibility issue with these older units – a missing signal) so for now I’m having to rely on the Toyota-supplied 120V charge cord and, oh boy, is that slow!  It takes over two days of continuous charging at 120V to get back to full from empty.  In other words, it still isn’t fully charged from when I brought it home on Tuesday night even though I’ve been keeping it plugged in as much as possible.  But this is temporary.  I’m getting one of Tesla’s universal mobile chargers (instead of a wall-mounted unit) and have it adapted to use the standard J1772 plug that the RAV4 uses.  Then my charge times will become very reasonable and I’ll be back to being fully charged whenever I want to go out — and it will give me extra flexibility when away from home.  A lot of RAV4 owners have done this because the Tesla mobile unit is really compact and convenient:  It’s small and portable and yet it will charge at whatever the appropriate amperage is based on the plug adaptor you use.  (12 amps @ 120V vs. 30 or 40 amps at 240V, based on NEMA plug type)


Update:  I have the Tesla charging cord now (modified Tesla UMC).  Seems well built and it has a hefty, secure-looking wall plug.  And I can now gain somewhere around 30 miles of charge back per hour.  Woot! Hardly necessary for overnight recharging, but handy when topping off between day trips!


Driving a Tesla Model S

I went to the Tesla Model S test drive event today in Fremont.  As a Model S reservation holder, I was able to go to the factory tour last November (here’s my pictures and video from that) but this weekend, with the delivery of the first vehicles to customers, this was the first of several drive events being held around the country this summer.

The test drive route was a nice mix of private and public roads and highways over about eight minutes.  There’s lots of pictures, videos and commentary available on the web already from this weekend but I thought I would add my feedback comparing it to driving my Nissan LEAF (and the Audi A3 3.2 that I used to own).

My first impression on pressing the accelerator and turning the wheel was “damn, this thing feels like a tank.”  It’s a beautiful, very fast tank, but oh does it feel big and heavy.  As a passenger at the ride-along last November, it wasn’t noticeable — because it is so quick and handles very well (even through the slalom course).  But when you’re behind the wheel and coming from the likes of smaller cars, you definitely notice the weight and the size.  I was disappointed by this.  I know it looks big but I had hoped to not be able to really feel it when behind the wheel.

Given that the Model S has a much more powerful electric motor than the LEAF, I think part of what I was feeling was how they’ve calibrated the accelerator.  (Or perhaps it’s really just the significant amount of mass you’re having to throw around!)  I suppose the LEAF’s accelerator is actually a bit touchy.  It leaps forward with just a slight press.  But then this contributes to the fun and lively feel of driving the LEAF around town.  And this despite it’s actually rather poor 0-60 time.  Of course, with full torque immediately available and no gears to shift, it is actually very quick at typical city speeds of 0-30/40 mph.  And its small size helps it feel more nimble than something like the Model S.  Of course the Model S is flat out faster (must faster than most cars and certainly most sedans) and it actually handles that speed and its weight far better than the LEAF.  Unlike the LEAF, it’s definitely engineered for performance.

But the Model S is still a big, “executive-styled”, “BMW 7-class series” kind of vehicle and isn’t really my kind of vehicle.  So I still have a lot of doubt about following through with a purchase.  Yes, it is expensive, as Tesla’s business plan is built around the notion of starting on the luxury end and working to bring down costs to develop a more affordable mid-priced electric vehicle.  While the expense is understandable – we’re still on the leading early-adopter edge for all electric vehicles, much like cellphones and plasma TVs when they were first brought to market – for this kind of money, I need to really love the vehicle as it is.  I’m not canceling my reservation just yet as I’ll probably have until the fall before I have to commit, but what I really want is a smaller, sporty, all wheel drive hatchback – all electric, of course!  Maybe I’ll have to wait for the third generation Tesla, the supposed Model E.  Or maybe somebody else will step up to the plate?

EV Car Hater’s Guide

Plugincars.com recently put out a couple of “guides” that make fun of all the anti-EV arguments — they’re up to two chapters now.  Kinda fun:


I definitely encounter these folk now and again — one today at a biking group lunch of eight or so who were otherwise enthusiastic.

New Shiny!!

Look at my new shiny! An all electric Nissan LEAF. Yay!

After a test drive of the LEAF at the SF Auto Show in November last year and discovering what a fun, surprisingly-roomy little vehicle it was, I knew I wanted to drive electric, even if it meant giving up my Audi A3.

Unfortunately, I also discovered that the waiting list was already closed, so I immediately jumped on the reservation list for the still-under-development Tesla Model S instead.  But this week I found out that I could take home an “orphaned” LEAF immediately despite the waiting list (though, for a premium).  This is a vehicle that somebody ordered but then decided to back out of – the dealers are selling them to other buyers willing to pay a little extra.  So I get to enjoy it while still waiting to see what comes of the Tesla Model S.

Awesome! Driving electric now!

Classic Car Show

Clay and I went to the Palo Alto Concours d’Elegance at Stanford to see some classic cars… and the Tesla Roadster!

Okay, it was really just to see the Tesla but the classic cars were great too!
