@  marchanna : (20 September 2014 - 04:37 AM) random?
@  you-are : (19 September 2014 - 09:17 PM) turbo
@  marchanna : (19 September 2014 - 07:07 PM) fair enough
@  FlossyTheSmart : (19 September 2014 - 07:02 PM) It's certainly not concerning enough to put any man-hours into it.
@  marchanna : (19 September 2014 - 07:01 PM) True, but if the moderator didn't approve it then it would be deleted and the space would be reclaimed. The issue of bandwidth however still remains, and I don't know if that is an issue or not.
@  FlossyTheSmart : (19 September 2014 - 06:56 PM) If you needed moderator approval, the image would still have to be uploaded and the space would still be taken up ;)  But we're not really that close to the limit anyway.  The inability to mass upload a huge number of pictures all at once though is naturally slowing the rate at which we fill up though.
@  marchanna : (19 September 2014 - 06:53 PM) Maybe for the time being having a moderator approval for all uploaded images to ensure space isn't exceeded.
@  FlossyTheSmart : (19 September 2014 - 06:53 PM) but of course, any time you upload an image to the site, you should be able to re-add it to later posts, using the "my media" button in the editor.
@  FlossyTheSmart : (19 September 2014 - 06:52 PM) nice***
@  FlossyTheSmart : (19 September 2014 - 06:52 PM) A gallery is an option, but would require more server space for sure. We don't have a huge amount of storage right now, and not having a photo gallery is probably keeping us from filling up instantly. I agree it would be ice.
@  marchanna : (19 September 2014 - 06:49 PM) I'm not terribly concerned with posting pics in the shout box. It would be nice alternatively to have a photo album that pics can be uploaded to, so that when we link images to posts there are permanent on the site and don't get lost when the source is shut down or hat not
@  FlossyTheSmart : (19 September 2014 - 06:21 PM) well yeah, but that's not necessarily intuitive.
@  Francesco : (19 September 2014 - 06:20 PM) even the regular interface allows BBCode including the[img] tag
@  FlossyTheSmart : (19 September 2014 - 05:58 PM) and clicking the icon next to chat with members opens a new window, which, as Francesco pointed out, is a pop-up. Not sure what else could happen.
@  FlossyTheSmart : (19 September 2014 - 05:57 PM) Yeah, the shoutbox isn't supposed to be anything permanent, so you can't upload images through it. If you go into the full shoutbox interface (Via the icon next to chat with members or the tab at the top), you should be able to throw in an image that you've already uploaded to the site. Ultimately, shoutbox shouldn't reaalllyy be used for sharing pictures.
@  marchanna : (19 September 2014 - 05:07 PM) I'll give a try on Firefox later
@  Francesco : (19 September 2014 - 05:05 PM) i don't have Safari for Windows, but it works as a popup on Cr, Fx and IE
@  marchanna : (19 September 2014 - 05:05 PM) I thought maybe the image was too big
@  marchanna : (19 September 2014 - 05:04 PM) I suppose, but it's not very useful or convenient
@  Francesco : (19 September 2014 - 05:04 PM) you have to use BBCode in Shoutbox, so you'd have to save the image somewhere online and link to it.

Electric car with "on board" generator

I thoought that this might be an interesting discussion to kick off here.How big would a portable 120/240v generator have to be to supply enough continuous energy run an electric car? I'm visualizing one mounted on a small trailer and plugged into the battery's charge circuit. Somewhat similar to a diesel-electric locomotive, where the internal combustion engine generates electricity to run the electric motors which propel the vehicle. It would increase the range of the car, but the fuel economy wouldn't likely be very spectacular. Whatever became of the fuel cell? That would be a natural, if it were developed to the level the original hype promised. Feel free to add your thoughts on this subject.

Consider that a high-efficiency electric motor running of lithium-ion batteries (think: Tesla) operates at perhaps 88% efficiency. A modern, four-stroke internal-combustion engine in a car operates at roughly 18% efficiency. In other words, you would have to supply roughly five times the input energy potential to a combustion engine just to get the electric drive train to run.

Overall efficiency will be far lower than if the ICE powered the car directly (ICE loss plus electric loss).....and the ICE used will probably pollute far more than a road legal car engine would, so it's a double hit against air quality and global efficiency. Far better to buy a new Volt if this is the way you want to go.

The efficiency of an ICE dedicated to a generator would likely be higher than that for one powering the car directly. It would be run at an optimum rpm to maximize efficiency. But there is no question that there are losses. The Jaguar C-X75 uses this principle, but uses gas turbines instead of an ICE to drive the generators that charge the batteries. Such a car can run on batteries when emissions are a problem, but extend range by running the generators when on the open road.

This has already been achieved in the Fisker Karma. http://www.fiskerautomotive.com/#!/kar...ions/powertrain This is quite comparable to the tesla but more refined. Alan

Wouldn't the on-sale-now Chevy Volt be the standard bearer in the plug-in hybrid segment, beating the Karma to market by a full six months? The Tesla Roadster and Model S are fully-electric vehicles. But calling the Karma more refined than the Model S is a stretch, since the Karma just began deliveries, and uses a Chevy Cobalt SS engine to charge an A123 Systems battery pack that is considered inferior to those made by Tesla. The electric motors are off-the-shelf units as well, unlike the custom Tesla units.

I think this has been well researched by corporations and shade tree mechanics as well. http://blogs.wsj.com...e-electric-car/ http://evmaine.org/h...v_trailers.html

Sorry the model S is a giant leap forward from the roadster, take my comments with a grain of salt for I have never driven either one. I was however under the impression that the volt only charged by plug and that the conventional internal combustion engine propelled the car after the batteries were depleted but did not recharge the batteries.

Nice car! To be exact though it is more like a luxury Volt than a Tesla - The Tesla is is a Plug-In EV - Fiskar has an onboard motor/generator for extended range. It will be interesting to see which manufacturer woes the buyers. The cars look very similar. Wikipedia notes that Fisker was fired as the designer of the Tesla S for 'substandard work'. Tesla tried to sue him because he incorporated the best of the Tesla S design into the Kharma. Odd to think of Tesla as the establish vendor and Fisker as the upstart! It seems that the smaller more agile companies are bringing better designs to market faster and with less investments than the big three. Will Tesla be the new GM? Interesting times ahead.

Because the trailer is not visible to driver due to its small size perhaps?

As an aside, Toyota announced that they will build the new all-electric RAV here in Ontario. It apparently uses the Tesla power train and will have a range of about 160km (without trailer!)It would be great if the EVs were supplied with a portable generator that could provide enough charge if batteries run out. If it could give you another say 20km, it would save a tow-truck fee!

It still doesn't make sense yet. He has a lens to see the trailer.

The article linked above mentions this:

The micro trailer incorporates intelligent "BackTracker" steering which automatically maintains trailer-to-vehicle alignment during backing to avoid jack-knifing.

Reversing a short trailer is particularly difficult, even for those with experience.
