Re: [EVDL] What is needed to build a successful practical solar vehicle.

[EVDL] Solar EV Boats (was Practical solar EV's)

A new definition of powerboat!!;^) Yes, the number of boats and mostly RV's just sitting in the sun 99% of the year are a great place to put solar panels and backfeed the house that 99% of the time. Though 4-5 mph for solar should be doable... Mine above does 3.3 knots on both trolling motors on full speed. Drops to 2.5 kts at HALF the power. But now I am humbled by looking at your amazing home-built below! I never thought of the autopilot! What a great idea. Because that is all I ever do, is just take a loop around the creek! Bob, WB4APR My Firefly's motors (http://www.evalbum.com/3432) are only about 800 watts total power from my crude homemade panel is 140 watts. This gives me roughly a 4.:1 ratio of charge to drive during daylight i.e. it take 4 hours of sunlight to allow travel for 1 hour. While that only means 3-4 miles of travel, it's more than enough to travel to the end of the lake and back. The boat was purpose built to fish, cruise and dive off on a small lake so big power or speed wasn't considered but it is still practical. Obviously more speed requires more power and the panel size and weight becomes an issue. I have a larger faster electric boat I plan to convert to solar some day ( http://www.evalbum.com/4767) but I expect the charge ratio to be 30:1 if the boat could maintain full throttle for 1 hour, but likely closer to 10:1 for normal cruising speeds.

Re: [EVDL] EVLN: PGE wants CA ratepayers to pay bill for $653M public
Rolling coal is a lot less cool than it used to be. A lot of diesel enthusiasts see it as waste, and don't really want the public hate (or stiffer regulation). My diesel will do this in certain settings depending on the rpm; I try to avoid it. I think for many, if it's going to have a sound, it needs to sound good. Quieter is better and allows you to hear your music. I used the most quiet muffler I could fit on my jeep, but admittedly the rumble of the 454 does sound nice. I do wish it was a little more quiet at times out on the trail. My son's jeep has a 4cyl, and the way it sounds, I wish it made no sound at all. Many new cars are very very quiet and that is a desirable selling point. Performance and convenience will win the day.

II think that intelligent, educated gearheads who will jump at EVs. However, EVs are missing a couple of things that other kinds of people want: noise and pollution. There is a sizable population of people who, for want of a better analogy (forgive me), like to mark territory. A clean vehicle won't do that. The din of a barely muffled ICE is part of the thrill. Of course some of that din can be simulated. As we've seen with the recent revelations that ICEV manufacturers are adding electronic exhaust noise to their cars, it won't take much to design an EV with an Enterprise-style whoosh or a nice, gear-y, turbine-like whine. (IIRC GM designed the latter into the EV1 deliberately.) But the type of guys who like to roll coal - you are NEVER going to get them into EVs.

(kidding) [Fuel] prices don't need to be especially high in such circumstances to make gasoline undesirable. Just the unpredictability and uncertainty alone will make people want to avoid it. What I think would do it more than price is consistent and significant inconvenience. During the 1970s mideast oil embargo, it wasn't so much the rising prices that got to drivers as it was lousy availability. In some areas of the US, buying fuel was a lot like buying TP or beef in Russia. Some stations had gasoline; many didn't. Where your gas gauge was didn't much matter. If you heard from a neighbor or relative (today it would be on the net) that a filling station had just gotten its allocation, you'd head over there to top off the tank, or buy your 8 or 10 gallon limit. You'd get there and find a line of cars stretching round the block. In winter they'd be idling, wasting the scarce fuel they were trying to buy. A cottage industry appeared, especially in university towns, with people who would - for a price - sit in your car for you in queue. It was a perfect job for college students, who could study while they waited. Of course it was mostly the upper crust VIPs who were willing to pay for that service. For the rest, a fuel efficient vehicle was suddenly REALLY desirable. Auto dealers had subcompacts sold, with hefty additional markup above sticker price, before they ever hit the lots. Used land yachts gathered dust on those lots before selling for fire-sale prices. (A friend of mine scored a once in a lifetime deal on a midsize car with a small V8, thanks to this scramble for small cars.) You can expect a similar demand for EVs if / when this happens again. In today's high-energy, hurry-up society, no one can stand to wait for anything. The rich folks will again be able to hire someone to get their fuel, but many others will be prime candidates for EVs. That just might be a good thing.

Re: [EVDL] PB-6 Extra Wire
There is one video I uploaded to my customers from my store, I made it to explain my Mexican customers how this work (Spanish), but you can see exactly how those 3 wires works. As lee Hart says; connecting the pot ends would give you a maximum resistance on the center and 0ohm on when turning it on each side. Not a popular connection on EVs. https://www.youtube.com/watch?v=L-63p-MA3UE Usually the 3 wires Pots are used for electronics where there is needed to have a positive and negative references for making the 'wing' process, from an 'X' specific voltage to another 'y' different than ground or ground too. For almost any EV controller you should only require one side and the center, depending on the controller input logic; from 0 to 5K ohm or from 5K to 0ohm. Other outgoing wires, if the PB-6 keeps original; only can be the micro-switch (that is 3 leads in it) for certain controllers as confirmation of 'end/start of track' or force to off mode in case the pot inside track fails or there is a false contact on the pot wiring.

Re: [EVDL] PB-6 Extra Wire
I am presuming that the intention of connecting wires together was to avoid the resistance to change more than the max value of the pot, you do this by connecting the wiper to one of the end wires, which turns the 3-wire pot into a 2-wire variable resistor as used in PB6. If you need to lower the value range of the pot, you can add a fixed parallel resistor from the wiper of the pot/variable resistor to the end wire at zero position. For example a 5k resistor (or 4.7k) added to a 5k pot will turn it into effectively a 2.5k pot (with a slightly different control range than an actual 2.5k pot, but that is not significant in most pedal controls). I have modified my potbox with a parallel and series resistor: - the series resistor keeps a very low output even at pedal up so my motor is idling - the parallel resistor shifts the active range of the pot away from where the pot has developed a bad spot so I can do more than on/off control that it used to give.

Then, connect one lead of your ohmmeter to the remaining potbox wire (the wiper), and the other ohmmeter lead to each of the above two in turn. With one of the ends, you should see a resistance that varies from 0 to 5k ohms as you move the potbox lever. With your meter lead on the other wire, resistance should vary from 5k ohms to 0 ohms. To connect this potbox to most 2-wire-potbox controllers, use the pair of wires that varies from 0 to 5k ohms. (Warning, some controllers require a 5k to 0 range, so test with a light bulb before testing with your motor!) If Roland's description is right, your ohmmeter should be able to identify the two wires that vary from 0-5k as the lever position is increased. Those are the ones you want to use with most controllers. See the above warning.

Re: [EVDL] Solar EV Boats (was Practical solar EV's)
Thanks Bob! . You have a dual drive like I do so it can be steered via the motors. I used a Sabertooth 2x60 motor controller, an RC controller with an Ardupilot in between, all the typical parts you would find a quadrocopter/ RC car. Remote range is great (line of sight) and there is an app that allows the pilot to be managed via tablet/smartphone. If you ever need more info on how I wired it all up just let me know.

A new definition of powerboat!!;^) Yes, the number of boats and mostly RV's just sitting in the sun 99% of the year are a great place to put solar panels and backfeed the house that 99% of the time. Though 4-5 mph for solar should be doable... Mine above does 3.3 knots on both trolling motors on full speed. Drops to 2.5 kts at HALF the power. But now I am humbled by looking at your amazing home-built below! I never thought of the autopilot! What a great idea. Because that is all I ever do, is just take a loop around the creek! Bob, WB4APR My Firefly's motors (http://www.evalbum.com/3432) are only about 800 watts total power from my crude homemade panel is 140 watts. This gives me roughly a 4.:1 ratio of charge to drive during daylight i.e. it take 4 hours of sunlight to allow travel for 1 hour. While that only means 3-4 miles of travel, it's more than enough to travel to the end of the lake and back. The boat was purpose built to fish, cruise and dive off on a small lake so big power or speed wasn't considered but it is still practical. Obviously more speed requires more power and the panel size and weight becomes an issue. I have a larger faster electric boat I plan to convert to solar some day ( http://www.evalbum.com/4767) but I expect the charge ratio to be 30:1 if the boat could maintain full throttle for 1 hour, but likely closer to 10:1 for normal cruising speeds.

1/4 mile drag race video of the new 2015 Tesla P85D against a 2015 Dodge
Challenger Hellcat. The 2015 ...
]
A YouTuber fed up with seeing the Hellcat fail because of the driver created
a video to teach people to race a Hellcat correctly: 7 Commandments for
Dodge SRT Hellcat Owners
[image] Two 2015 Dodge Challenger SRT Hellcats [ice]
Both the Dodge Challenger and Charger SRT Hellcats lay down 707 horsepower.
They should be dominating the competition left and right at the drag strip.
Yet a number of videos have been uploaded to the interwebs showing less
potent cars destroying the Hellcats on the strip. Why? It’s not because the
Hellcats aren’t good; it’s because the drivers aren’t.
One YouTuber, bigtruckseriesreview [
https://www.youtube.com/channel/UCe1kDlxUzWTdjMAGCo956UA
] is fed up with dealing with internet trolls who tell him that the Hellcat
sucks and that his penis is small (we’re just guessing the second part). He
is especially angry at the video below, which shows a Tesla Model S [EV]
obliterating a Challenger SRT Hellcat [ice] at the strip.
So naturally, he created a very eloquent (not really, he actually uses lots
of bad language) video entitled “7 Commandments for Dodge SRT Hellcat
Owners.” Check it out, but remember, it’s definitely NSFW and also more than
a little bit (a lotta bit) sexist:
What are the main takeaways from this incredibly grouchy man with wounded
pride? Here are a few:
-Use the damn red key, for the love of god, no matter what, unless you’re a
girl because you’ll wreck the car. (Did Saleh al-Saadoon make this video?)
-Teslas are for liberals, and liberals are for Canada, and Canada is for
communists.
-Use the shift light system, dagnabbit.
-If you’re old, learn to use computers or die. You’re no good to society
alive but stupid.
-Widen those rear tires. What were you thinking?!
-All-wheel drive is for squares. And squares belong in Canada, and we
already covered Canada.
-Why the hell are you racing with a retracting spoiler?
-Don’t race an electric vehicle because you will lose, and who wants to lose
to a sissy EV? Trees can kiss my butt.
-Don’t race planes. Probably because your car can’t fly.
-Get your shit together, guys. Come on.
Seriously, despite the guy’s flaws, he does make some valid points as to how
to race with your Hellcat. If you’re interested in taking a Challenger or
Charger SRT Hellcat to the drag strip, keep the video’s 7 commandments in
mind. Unless you’re a girl, because [according to bigtruckseriesreview] you
shouldn’t be driving a Hellcat [ice].

Tesla Motors reportedly goes Apple picking on a regular basis, padding its 6,000-strong ranks with a number of former Cupertino-ites. The automaker has hired at least 150 former Apple employees—more than any other company, according to Bloomberg. Tesla CEO Elon Musk and his lineup of electric vehicles serve as the modern equivalent of Steve Jobs and the first iDevices. Musk and Jobs, Bloomberg pointed out, even share similar reputations: a quick temper and obsessive attention to detail. So is it any wonder that Apple workers are flocking to the hottest car maker in the country? From a design philosophy, (Apple) is relatively closely aligned, Tesla CEO Elon Musk told the news site. Neither Apple nor Tesla responded to PCMag's request for comment. In October 2013, Doug Field ditched his position leading Apple's Mac Hardware Engineering team for a spot as Tesla's vice president of vehicle programs. Until Tesla came along, I had never seriously considered leaving Apple, Field said at the time. As the first high-tech auto company in modern history, Tesla is at least an opportunity for me and many others to pursue the dream of building the best cars in the world—while being part of one of the most innovative companies in Silicon Valley. Musk has been poaching Apple workers since 2010, when Tesla hired George Blankenship to head its showroom design and sales efforts. Tesla has also pulled in executives from tech giants like Google, VMware, and NXP Semiconductors, as well as rival car makers Ford, Mazda, Toyota, and Daimler. Apple, however, is fighting back, reportedly offering $250,000 signing bonuses and 60 percent salary increases to Tesla employees who join Apple. Apple tries very hard to recruit from Tesla, Musk told Bloomberg. But so far they've actually recruited very few people. Last year, Musk confirmed that he had informal talks with execs at Apple, but he denied any acquisition plans.

It is no longer surprising that Elon Musk’s and his teams technology vision has found solutions and technology experts at Apple’s DNA-structured headquarters or closed-laboratories, for Tesla Motors continues to hire more experts from here. Ex-Apple employees at Tesla One of the best examples of recent hiring patterns by the world’s most famous electric car builder has been Doug Field. Field who is a technology officer and has roots deep in product and hardware design first at Segway and then at Ford, and later at Apple’s MacBook products, eventually became Vice President at Tesla Motors Vehicle program. At last count, Tesla Motors has over 150 of Apple best and brightest now on its payrolls. In CEO Elon Musk’s words, Apple’s engineers share the same ‘design philosophy’ and closely match the vision Tesla has into the future. Tesla Motors Inc use of software on its cars has brought about profound changes in the automotive industry, thus far. As analysts remark, higher software-driven cars development has meant that the traditional car makers are under pressure. The impact of the ex-Apple Inc. based employees is felt in the design of the 2012 car release the Model S, a full-sized sedan. The touchscreen based controls for many of the function and smartphone, device-like software updates are rendering similar user-experience as the iPad or an iPhone. However, it needs to be seen how far the people at Tesla Motors Inc will opt to be an Apple-like product and when the style differentiation will begin!

[EVDL] EVLN: Tesla Model X Beta Prototype Spotted Testing
http://gas2.org/2015/02/12/tesla-model-x-beta-prototype-spotted-testing/ Tesla Model X Beta Prototype Spotted Testing Christopher DeMorro 2015/02/12 [images / yobigd20 http://gas2.org/wp-content/uploads/2015/02/model-x-prototype-1.jpg (X Beta) http://gas2.org/wp-content/uploads/2015/02/model-x-prototype-4.jpg http://gas2.org/wp-content/uploads/2015/02/model-x-prototype-5.jpg http://gas2.org/wp-content/uploads/2015/02/model-x-prototype-3.jpg http://gas2.org/wp-content/uploads/2015/02/model-x-prototype-2.jpg ] During last night’s quarterly report call, Elon Musk mentioned that though the public wouldn’t see the final, finished Tesla Model X before deliveries began, there were already about 30 “beta” prototypes testing on the roads. Coincidentally, one of these prototypes was spotted by a Tesla Motors Club forum member, just hours ahead of Musk’s big call. The camo-clad Model X prototype shows much of the same design as the original concept, barring the addition of real sideview mirrors as opposed to the video cameras Musk would prefer. You can clearly make out the falcon-wing doors, which are partly responsible for the repeated delays of Model X deliveries. From the back, it looks a lot like other crossovers and SUVs on the road with a fat booty and high waistline. The front end also looks a like like the Model S sedan, which should come as no surprise since the two vehicles share a platform. Last night Musk mentioned that there are features on the Model X the public doesn’t even know about yet. Considering features we already know about, like the falcon-wing doors, towing capacity (a first for a production electric vehicle), Dual Motor all-wheel drive, and an optional third row of seating, it’s hard to imagine what Musk might have in store. For those Tesla Model X reservation holders, these spy pics are the closest we’ll get to seeing the electric SUV before deliveries begin later this year.

In other news, a member of Tesla Motors Club forum shared a photo of a beta version of Model X, spotted in California a few days back. The picture reveals a four wheel electric SUV in a pitch black color, gliding across the streets. Model X’s door mirrors can be seen in the photo, which will most likely be replaced with video cameras to make the design aerodynamic. It is thought the door mirrors pulls back the vehicle to boost maximum drive range. Second photo of Model X reveals the rear-view of the vehicle, where the gullwing doors can be clearly seen. On display is the width of the gullwing doors, which are touching the rooftop of the vehicle. The automaker has been delaying the launch of the EV for almost a year. At first, the Palo Alto-based automaker announced the Model X would hit markets by late 2013, but later the launch was delayed to “somewhere in 2014.” Last month, Tesla Motors Inc CEO Elon Musk confirmed the Model X will be on roads by the third-quarter this year. In its 4QFY14 earnings release on Wednesday, the company announced that currently 30 beta version of Model X have been built, and are currently in the testing phase. So far, the crash results of the beta version have been great, and will meet up to “high safety standards set by Model S.” The company’s press release further mentioned that Release Candidate Model X will be tested in March, which will have a design close to the final version. The vehicle will be all wheel drive (AWD), and carry similar dual electric motors that are used in Model S.

Re: [EVDL] PB-6 Extra Wire
I looked at Marco's Youtube video and even with my poor understanding of Spanish, I can understand how the Pot works.

Not a popular connection on EVs. https://www.youtube.com/watch?v=L-63p-MA3UE Usually the 3 wires Pots are used for electronics where there is needed to have a positive and negative references for making the 'wing' process, from an 'X' specific voltage to another 'y' different than ground or ground too. For almost any EV controller you should only require one side and the center, depending on the controller input logic; from 0 to 5K ohm or from 5K to 0ohm. Other outgoing wires, if the PB-6 keeps original; only can be the micro- switch (that is 3 leads in it) for certain controllers as confirmation of 'end/start of track' or force to off mode in case the pot inside track fails or there is a false contact on the pot wiring.

To convert to a 2.5 K Pot, you can still connect the two ends together. Something's not right here. If you connect the ends of a 5k pot together, you end up with a 1.25k pot. As you turn it from one end to the middle, the resistance would go from 0 to 1.25k. As you keep turning it to the other end, the resistance goes back DOWN from 1.25k to 0. Such pots are used in wig-wag throttles, where it is spring-loaded in the center. They use these on electric pallet trucks, for example. You operate the throttle with your thumb. Pressing it to rotate one way is forward, pressing it the other way is reverse. A further complication is that the Curtis pots are weird. Instead of a resistance track that covers the full 300 degrees of rotation, they had it printed on only about 90 degrees, with solid metal for the remaining 210 degrees. On this kind of pot, you get 0 to 5k as you rotate it from 0 to 90 degrees (normal throttle usage). But then it STAYS at 5k as you keep rotating it the other 3/4 of a turn. If you connected a wire to the far end of this kind of pot, it starts at 5k, decreases from 5k to 0k as you rotate it 90 degrees, and then STAYS at 0 ohms as you rotate it the other 3/4 turn. So I don't know what you really have.

As far as I know the Xof1 car still holds the long distance record, at 35,000 km. Canadian Marcelo Da Luz and numerous volunteers and helpers built a purely solar powered car and drove it all over the U. S. and Canada beginning in 2008. Marcelo drove it from Niagara Falls to Chicago, Bemidji, Winnepeg, Moose Jaw, Edmonton, Dawson City, Inuvik (the furthest north one can go on a road), Anchorage, Whitehorse, Vancouver, Seattle, Portland, San Francisco, Los Angeles, New Orleans, Key West, Baltimore, and Pittsburgh. It retraced its earlier journey back to the Arctic Circle and Inuvik again, in August 2009. The car was very aerodynamic, was quite uncomfortable, weighed 460 pounds, carried 960 watts of PV and approximately 4kWh of Kokams lithium ion batteries. The body tilted up on struts for charging while stopped. It traveled 300 miles one sunny day, and even 130 miles at night. Top speed was 75 mph. Its consumption was 25 Wh per mile, more than ten times my own EV’s efficiency. Marcelo never charged from the grid. Curiously, the province of Ontario where Marcelo lives, prohibited solar cars at the time; maybe it still does.

Re: [EVDL] What is needed to build a successful practical solar vehicle.
I found some of theses Ev scooter used, with just a few k on them, but they have a such a small battery pack . I'd like to know what voltage this pack is, I'm sure I could build a pack with the extra LFP cells, increase my range. Ideas or where I could find this info.?? ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)

If they have batteries now, have you disassembled what they have to see how many cells it has, and what type?
