Electric Compact Equipment
Does anyone know of electric skids or other compact equipment? If so, do you have any ideas where they may be used, Mines? Tunnels? Other indoor environment? Have you encountered night work in city centers where there are noise/pollution restrictions that would require use of electric vehicles?
The thinking is that with the new Obama administration stress on Green, there may be some potential there...

DavidLevin,
I fear that the gummitup may be on a course to destroy our nation.
The push for electric vehicles has me laughing....a lot......and scratching my head even more.
For the life of me, I can't figure out how the gummitup figures to supply the billions of extra kilowatts of electricity we'll need to charge our vehicles while at work, and again at night after arriving home from our evening commutes.
The nation's electrical grid simply won't handle the extreme increase in electrical power that will be required to replace the power we currently get from gasoline.
And what are we going to have to burn in order to make all of this additional electricity? Coal.....right? But I thought the entire GREEN program was designed to ween us from these filthy fossil-fuels.
Me thinks we're spending a whole lot of money just to go in circles.
Joel

David, for decades there've been forklifts powered by batteries or propane. I bought a small tractor powered by six golf-cart batteries in 1972, and it's worked hard for me since with just new batteries every 5-7 yrs. Similar units work in barns and greenhouses. I've heard of battery compact tractors but haven't seen one. Other heavy battery-run industrial equipment is rare, but I'm sure will increase as battery technology improves over lead-acid. There are sites devoted to this topic.

Joel, a couple of points:
1. The "green" footprint of the energy (assuming coal) required to charge your batteries would be less than that of combustion engines.
2. The idea is that Coal will not be the only way to power up the grids.
Either way, can't stop the investment train in Green. Question is, where/when/how will it fit with tractors?

DavidLevin, our Israeli friend, I have been following your many posts on the web about this and the easy-on/off tracks for loaders on other sites.
To the others here that don't know about Mr. Levin he purports to represent a major manufacturer in Israel--but won't give any details as to his involvement. (Me thinks this a teenager dreaming up ideas--IMHO, of course)
While there is some entertainment value you bring to the table, I'm highly suspicous of a. your credentials and b. your approach which at best is amaturish. Think about it: The brain-trust at your "corporation" must be empty; no self-respecting corporation would be asking the questions you ask--even in light of the boundless resources of the internet. (BTW, elctric equipment has been around in Europe for decades---BUT it's NOT rechargeable AND needs a power cord) And by that I mean you could easily google any search word and found a result.
Be that as it may, you will continue to ask inane questions and won't stop until someone tells you the answer you seek.
So here it is: Yes the world needs electric compact equipment. Knock yourself out.

If my "cordless tractor" is anything like my cordless drill, I'll use the front end loader to dig a big hole.......until the batteries go dead......then I'll use a hand shovel to bury it.

Hello, my name is Avishay and I am a colleague of Mr. Levin. One thing I am sure about is that he is no teenager! (sadly for him…)
I have founded the company some 10 years ago- www.galileo-mobility.com - and we are trying to find different application for the track wheel mechanism we have developed.
So far we have built a prototype for a climbing stairs wheelchair and a portable Military robot known as 'VIPER' (currently been field tested by Israeli Army)
Recently we have been asked whether we can fit our mechanism to a large tractor, so what we are trying to find out with your help is, where if at all lay the benefits of our technology in your world.
The reason we are asking about electrical tractors is due to the fact that one of the major qualities of our mechanism is energy efficiency since we only operates on wheels when needed and stay on wheels as long as it is possible. And as you know tracks tend to draw more energy than wheels.
That fact comes to be more important when your energy source is batteries as oppose to fuel.
As we are not familiar so much with tractor world we can only imagine where electric tractor might be in use, but those are only guesses.
We thought of places where diesel fumes cant be tolerated, in closed places such as tunnels, mines, etc. we can guess that there might be a need for an electric tractor when job need to be done in an urban environment, and that work need to be done at night time to avoid traffic, but loud noise can be a problem too.
Again these are only our guess and we would like to here your opinion about how far or close from reality they are.
Sorry for my unpolished English and we will appreciate your cooperation.
Avishay.

Shalom, Avishay, thank you and I'll try to help.
I saw a video on your wheel-track mechanism, and can now respond better to David Levin's original question. You use a clever and unique flexible wheel-cover that can be automatically expanded to include a pair of bogey wheels, increasing the ground contact and therefore the traction, and allow it to climb stairs. That works on small, light applications like wheelchairs and robots, but I do not see any flexible material having the strength needed for agricultural or construction equipment.
As for batteries, yes they can provide plenty of clean, quiet power (think of World-War II submarines) but they are so heavy (the 24V ones used in many forklifts must be installed/removed by machinery) that the first step has to be more power-dense batteries. And that problem (for the desperate car industry) always seems to be next year's solution. But there are companies selling small tractors like mine, as well as low-speed "city cars," powered by lead-acid batteries.
NEW: on Reuters UK, see the clip called "China's Walking Chair." It's an equally elegant but mechanically different approach to a stair-climbing chair.

Seems like someone here on TP talked about an electric tractor he was recharging with a solar panel. I don't remember much more about it.
