Cougar Open Revolt Power Stage Milling

If you have been following the "Cougar Controller", now known as the Open ReVolt, you know it has taken on a life of its own!

Started by our friend Paul, with the early version tested in the Electro-Metro, another member of the crew is now MANUFACTURING the circuit board for the latest version. Here is the power circuit board being milled.

Can you spot what's wrong with this picture?

I will give you a hint:
That's an electric car.

This is the first time there has been any gasoline in that car in over a year - since the car's gas tank was removed to make room for batteries to power an electric forklift motor that replaced the car's gasoline engine.

Unfortunately, I have been neglecting my lawn for the past two weeks as I was traveling to an "eco-bed 'n' breakfast" and then off to the big renewable energy fair.

While my car is powered by electricity, my lawn mower is not. Nope, I am stuck in the fossil fuel age when it comes property maintenance. Although my long-term goal is to have a bigger garden and planted areas, for now I must trim my lawn to acceptable neighborhood standards.

A few weeks ago, I had an appointment to go see an Elec-Trak (GE-built electric riding lawn mower) that was for sale, but had it stolen out from under me by somebody who swung by and dropped off a load of cash, sight-unseen!

My friend Tim, with help from all our EV Buddies of the Milwaukee Electric Car Club, are converting an old Simplicity lawn tractor to battery electric. Once done, Tim will be able to mow his lawn fossil-fuel-free.

Although I am busy with several other projects, I think something similar would be great. We'll just let Tim be the Guinea Pig on this one.

So for now, I have to use my electric car to go buy gasoline for my petro-mower.

The irony is not lost on me!


(PS: Safety first! Yes, the windows were kept open, and there were no EV parts near the gasoline capable of igniting any fumes)

Back at the MREA Energy Fair!

June 18, 2009
Custer, Wisconsin.

Right now, I am sitting on the futon of a new friend in Stevens Point, Wisconsin, just miles from the Midwest Renewable Energy Fair in Custer.

This year is the 20th anniversary of the fair, and it's bigger and better than ever.

My particular interest is in sustainable transportation. Lucky for me, the fair includes an entire Clean Energy Car Show. In fact, that's why I am here - to show off a pair of home-built electric vehicles - both a car, and a motorcycle.

Although my interest in clean transportation most likely started with the electric motor my brother put on his bicycle as a kid, my most recent foray into clean transportation started here, at the MREA, three years ago.

I saw a bicycle with a front-wheel drive electric motor on it.
Brilliant! The front tire pulls you along, and you can still pedal with the rear! A plug-in hybrid bicycle.

When I got home, I plunked down the cash (ok - debit card, it was mail order....) to buy an "electric bicycle kit".

The kit included an entire front wheel with motor, controller, charger, and the other required doo-dads - just add a bike and batteries! I hit up my local thrift store and found an old ten-speed, complete wire wire rear baskets - perfect to hold the batteries!

A couple hours later, I had an honest-to-goodness electric bicycle! No more gasoline for me! Just fresh air and sunshine, and silent 20 mph cruising without pedaling!

While I zipped around in an electric euphoria for much of the summer, I eventually found that it wasn't the perfect vehicle for me.

The ten-speed frame had NO suspension. Terrible on my rough country roads. Worse than that, I was shocked how cars treated me. Vehicles constantly pulled out of driveways RIGHT IN FRONT OF ME. I suppose my grannie panniers did not add to the speed-demon image. Indeed, a headlight and horn would not have been back additions.

Hmmm. Suspension. Lights. Horn. Something that says - "Get out of my way! I'm really flying here!" I believe that's the definition of a motorcycle.

That's right a motorcycle - not an engine cycle.
A motorcycle is really just a big bicycle. It couldn't be too hard to make one of those to be electric, could it?

I then began my quest to build an electric motorcycle. Eventually, I found one cheap. The engine and transmission were shot, the tank was dented, and there was no title. But it met my main requirement. It was cheap!

I went to the library and found a book about converting vehicles to electric, and bought an electric motorcycle guide through the internet.
I scrounged for parts on E-Bay, finding an electric motor being sold from college robotics battles, and purchased a motor controller through a golf-cart store.

The motorcycle was really coming together. Of course, I have no background in welding, nor do I really have any tools beyond a socket set. Everything on the motorcycle was simply bolted in using threaded rod through the original frame mounting points.

The motorcycle was ready and on the road only days before the MREA Fair, exactly one year after I had first seen that electric bicycle. Of course, it wasn't pretty, and it was running on the tiny 18ah batteries that I had been using for the bicycle.

It wasn't until the next year that the motorcycle was back at the fair with the Optima Yellow Tops.

I love the motorcycle, but it still isn't the perfect vehicle for Wisconsin, especially the 8 months of the year with snow on the group. If only I had some sort of motorcycle with a roof and more than two wheels on the ground.....

Of course that then lead me to thinking about building an electric car. Come on! I gotta be kidding myself. How could I possibly build an electric car?

Well, I already learned some basics working on the motorcycle. The car is heavier, needs more batteries, but is pretty much the same otherwise, right?

Well, it's a bit more complicated than that, but in the year in a half since I decided to build an electric car, I have learned more about motors, power brakes, batteries, guages, watts, ohms, amps, cables, and myself, than I ever thought possible.

I have made new friends, chit-chatted with the Tesla salesperson as I sat in a Roadster, learned that brake fluid and plasma cutters are a bad combination, and so much more. I even bought a 1970's street legal electric car, met the creator of the vehicle, and drag-raced it (winning!) against others.

Now, I have been asked to consult on a battery-powered vehicle for a net-energy-producing "house of the future".

So here I am, at the Energy Fair again, where so much of this started, ready to show off both an electric car and motorcycle I couldn't have DREAMED of a few years ago.

Last year, I lost my voice speaking to so many fair attendees about clean transportation. Just two weeks ago, I installed the cheapest radio I could buy in the Metro. One of the radio features is MP3 audio playback from a solid-state USB thumbrive. Rather than answer the same questions over and over - How far does it go on a charge? What's the top speed? - I will simply record a sound file and have it play through the stereo.

This time, the work will simply speak for itself.

Prius 70 MPH Electric Mode (Second Demo): Ewert Energy Systems

The Ewerts are at it again!

This time with a more watchable / less bouncy demo of the 70 mph EV Prius mode! Filming during the day makes the view screen much more watchable. They also answer a few questions that people have asked since the first video.

Electro-Metro Instrument panel

I am trying to get as much "spit and polish" on the car as possible right now.

The MREA energy fair - the largest in the Midwest, and one of the largest in America, is only a week away, but I am gone all next week!

I just got the dashboard back in with the new stereo, and mounted the ammeter, volt-meter, vac guage, and 12V gauge.

Still not really a "final" version, but it is functional and looks much better than what was there!

Next Up: Zip-tying ALL the loose cables under the hood!

Local man builds electric car

Here's a little news piece on a guy in Indian who did a really nice conversion on an Eagle Summit.

I like the green lightning on the side of the car! Sort of what I was thinking for my Metro!

Prius 70 MPH Electric Mode: Ewert Energy Demo

A Prius that can go 70 Miles per Hour on just electric?

Yep! A couple guys in Chicago just did that last night!

Just watch the video! (Or listen to it, the video is a little bumpy!)

Ride the Citicar ! Tomorrows technology, yesterday.

I spoke with a guy in Madison on his way to the HotRod power tour who had a Amphi-car. In talking with him, I found out he bought it from a guy in Illinois who restores them.

That guy is known as "Dave the Wave".
I was also told he had a Citicar.

I looked him up and found a YouTube video I had seen before. It features Dave the Wave and his Citicar.

Chicago EVs and Alt. Autos

Recently, I had a chance to speak with George Gladic on the phone about his Prius converted to a Plug-In Hybrid Electric Vehicle. (PHEV)

George and other members of the FVEAA (a Chicago electric car club) are featured in this video.
