Mount Conversion
 How do I do an electric vehicle conversion without using the transmission? I would like to convert my 99 Toyota Tacoma 2wd to battery electric. Every conversion kit that I've come across involves bolting an electric motor to the existing transmission. I would like to remove the transmission and mount the electric motor directly to the drive train. I've heard this can be done successfully but there is little information available. Anyone have any experience or ideas on this? I like your thinking -- I agree getting rid of the tranny is a win. However, the folks on the EV List http://www.evdl.org/ have discussed this at great length, and from their experience I can tell you there are several ways to go about that, and all have compromises. The problem is, most single DC motors don't have the torque spread to both freeway cruise at 60 mph and also mountain-goat up really steep hills. You also need to figure out how to apply power in reverse. #1 AC drive. This makes for a very complicated and expensive controller but a somewhat cheaper motor. AC can do *everything* - mountain goat, freeway cruise, reverse, regenerative brake. To buy a commercial motor/controller package you're looking at $8000 and up. Ouch. #2. forget about freeway. Use a low final drive gearing that will climb you up the hills, and just don't go faster than 45/50/whatever. #3. forget about hills. Use a tall final drive gearing that leaves you unable to mountain-goat. #4. Oversize the DC motor. Put a 9" in a car you'd normally use a 7" motor in, or an 11" where you'd use a 9". #5. TWO series-wound DC motors and switch them from 'series' to 'parallel'. Almost every railroad vehicle does it this way. Series for climbing hills, parallel for freeway. An alternative to "parallel" is "single motor", i.e. short around one motor, simpler switching but less power available. #6 Separately Excited DC motor. The controller is somewhat more complicated and the motors are much harder to come by, you might have to take a series DC motor and pay a motor shop to rewind the fields for SepEx. We still need to discuss "reverse". Without a transmission, you'll need to electrically reverse the DC motor. That is, reverse polarity of either the field or armature. For that, you'll need some physical switches. It's the same kind of switches you'll need to select series/parallel. It might be possible to implement all that, together, in a big drum switch of some kind, similar to a streetcar "K" controller. All of this is going to require some engineering, especially to get the final-drive ratio right. That's one reason so many conversions use transmissions, makes everything simpler as you can just correct for gearing deficiencies by changing gears. That would be one hedge, keep the tranny temporarily until you figure out how to have the vehicle do everything you want in 4th (direct) gear, then dump the tranny. |

Wall Mounted Fountains Make a Decorating Splash
Wall mounted fountains can be found in many public places, but have you ever thought of a fountain in a home. If you have ever looked at the beautiful homes in magazines, you will have seen how elegant they look but you could never have one.
Why not?
You may not be able to afford one of those large stone fountains that dominate the foyer of top end hotels and stately homes but there is no reason why you cannot enjoy their beauty and elegance in your own home.
It's easy to be sold on an idea of a wall mounted fountain with its soothing tinkling music playing gently on your ears, but at what cost? Believe it or not, a wall mounted fountain can be surprisingly inexpensive and add so much to a home.
If you are considering remodeling or decorating your home, you may want to think about adding a wall fountain into your plans. A wall mounted fountain is the ultimate in design statements and an excellent way of adding beauty to an empty wall.
You will often see wall mounted fountains in offices or the waiting rooms of medical suites because they promote peace and relaxation as well as providing an unusual and pleasant appearance with their eye catching appeal. There is no reason why you cannot create the same ambience in your own home.
Indoor wall mounted fountains have a surface typically of slate, copper or fiberglass resin down which water flows. The water seeps into a reservoir and recycled to the top of the fountain. Indoor wall mounted fountains require minimal attention and no plumbing is needed so they can be added to any wall in your home.
Wall water fountains with their soothing sounds bring the purest of nature's substances into the home or office. Water fountains for the home or office are typically tabletop, freestanding or wall mounted. I find that the wall mounted water fountain to have more impact than either the freestanding or tabletop styles.
Wall mounted fountains are also the most practical of the three types of fountain. Not only are they pleasing to look at, these artistic masterpieces are also extremely comforting andsoothing and stimulate your ears with their gentle trickling sound.
The sounds of indoor water fountains has universal appeal and the calming "white noise" is believed to help concentration.
The uniquely elegant and stylish design of a wall mounted fountain will transform your home into a masterpiece.
A wall mounted fountain can be your homes centerpiece and the conversation piece of your parties. Create an ambience that will combine the visual appeal of falling water with the soothing sound as it trickles over the stones in the basin.
Why not own the home that makes a splash. How many friends do you have that have their own indoor water fountain?
Indoor fountains can be found at most home improvement stores, specialty design and fountains stores and even through parties and online auction sites.
Indoor wall mounted fountains are the fastest growing trend in remodeling and decorating techniques. They are surprising modestly priced for what you get and can be installed with the minimum of tools. There is no plumbing, they take up relatively little space, they are a pleasure to see and they have health benefits.
