The Art & Science of Battery Charging and Battery Rejuvenation

Robert L. “Bob” Sewell – Regenerative Electric Car Inventor

It’s difficult to say who developed the first electric car that charges it’s own batteries by coasting down a hill and having the motor become a generator.

One thing is for sure, in the 1950’s, Bob Sewell, of Spokane, Washington, retrofit a 1947 Crosley Station Wagon with an aircraft starter motor that exactly accomplishes these regenerative methods and he did it as an Electrical Engineering student at the University of Idaho.

It made national news and was even featured in a full page story in the November 1957 issue of Popular Mechanics. See it here: November 1957 Popular Mechanics

Bob Sewell
In a popular article about electric cars back in 1960, which was published in the Saturday Evening Post, Bob Sewell is even mentioned in the same paragraph as the legend Charles Proteus Steinmetz. Apparently, Steinmetz had worked out the regenerative electric car back in 1913.

As the subject heats up, ideas keep popping out: Why not put electric chargers on parking meters, an extra dime giving a parked car ten miles of recharge while it waits? Why not design the motor to become a generator going downgrade, recharging the battery and helping to brake the car? Charles P. Steinmetz, the electrical wizard, had that worked out in 1913. Robert Sewell, an engineering student at the University of Idaho last year, now with Washington Water Power, has applied this idea to an electrified Crosley station wagon.

See the original article: Are Electric Cars Coming Back?

Bob recently passed away so there is a lot we’ll never get to share with each other in regards to some fun and exciting electrical experiments. He definitely had a sparkle in his eye when I told him about some of the work of Eric Dollard, Jim Murray and others we’re involved with. Whenever Eric Dollard stayed at my home, he parks his car in perfect view for Bob to see all the antennas on it – something Bob could appreciate as a Ham Radio operator. Bob Sewell was my neighbor.

I’ll always remember him waving at me every time he drove by my house in his little maroon PT Cruiser, literally driving about 2 miles per hour. Happy travels Bob!


Robert L. “Bob” SEWELL (06/07/1934 – 11/07/2014)

SEWELL, Robert L. “Bob” 1934 – 2014 Passed away November 7th 2014, at his home in Spokane, WA of natural causes. His wife of 54 years, Helen (Pugh), preceded Robert in death in May 2010. Robert is survived by son Donald (Kathy Rigsby-Sewell); grandson Tyler (12); daughter Mary Ann Sewell-Driftmeyer (Todd); and Sister Barbara Sewell-Young (Steve). Robert was born June 7th, 1934 in Orofino, ID to Byron and Pauline (Holstein) Sewell. He graduated from Wallace High School in 1952 then attended the University of Idaho, working as a Hasher in Kappa Sigma Fraternity to put himself thru School. While there in Moscow, Bob built one of the World’s first electric cars which he often drove around campus and was featured in the November 1957 edition of Popular Mechanics. It was also during his time at U of I that he met his future wife, his ‘Florence Nightingale’ Nurse Helen Pugh. While home on Christmas break from College in December 1954, Bob developed Appendicitis and was rushed to the E.R. at Deaconess Hospital in Spokane where Helen just happened to be working that day and as they say…the rest was history. He married Helen Louise Pugh at the Hillyard Baptist Church on Sept. 15, 1956. After graduating from U of I in 1957 with a degree in Electrical Engineering, he worked for the Washington Water Power (Avista Corp.) from June 1957 to December 1989 when he took early retirement. In the late 1950’s/early 1960’s, Robert was instrumental in design and development of most of the region’s infrastructure of high-voltage Transmission and Distribution lines built to service the region’s burgeoning Hydroelectric Dams. He was published both regionally and nationally many times, receiving numerous awards for Inventions and patented devices. In 1970 he designed and built his and Helen’s ‘dream house’ on in north Spokane where he lived for 44 years. As Superintendent of Electric Underground and Water, Robert was a major cog in transforming the downtown core of Spokane for the World’s Fair in 1974. Robert was involved for many years in Lion’s Club, Eagles Lodge, Spokane Lilac Festival, Avista Corp. Trailblazers, U of I Alumni Association, enjoyed taking the family on Summer vacations all across the United States and boat camping at area lakes with the Spokane Yacht Club, owning and mounting accessories to unique one-of-a-kind Campers, collecting and wearing hats, was a student of history, loved reading books, loved museums, Auto Drive-away adventures, numerous excursions with Inland Empire Tours, ham radio, car shows, antique and vintage cars, jazz festivals, ‘Big Band’ music, playing in the U of I Pep Band, anything World War II, Hillyard Senior Center, the Silver Café, thrift stores, pawn shops, yard sales, classified ads, auctions and last but not least eating/food especially juice, milk, ice cream and anything chocolate! A Memorial Service will be held Friday December 12, 2014, 2:00 pm at Country Homes Christian Church, 8415 N. Wall Street (SW Corner of Wall and Country Homes Boulevard) Spokane, WA 99208 followed by fellowship time. In lieu of flowers, memorials may be made to Union Gospel Mission Ministries P.O.

Adam Abraham – Phaelosopher

Earlier this year, Adam Abraham, a researcher, videographer and advocate for natural and safe  healing modalities, green energy solutions and other related topics, came to Spokane for business relating to his water research.

We had already connected in the past so this was a great opportunity to introduce him to a lot of the movers and shakers in the local area who are known in the “free energy” world. He met with John Bedini, Peter Lindemann, Paul Babcock and even stopped by to visit Eric Dollard on his way back down to Arizona.

Here are two videos that he posted on YouTube and there are more to come. The first is an interview with Peter Lindemann on what is Free Energy and the second is a brief overview of what we do at Tesla Chargers. Please give Adam’s videos a thumbs up to show your support and share this post with your friends!

Tesla’s Technology Miniaturized And Simplified For The Masses

Tesla’s Technology Miniaturized And Simplified For The Masses
Legacy of a World-Class Inventor & Humanitarian

Spokane, Washington – November 2, 2014

Fifteen years ago, Shawnee Baughman of Coeur d’Alene, Idaho was competing for an elementary school science project and an electronics wizard happened to work in the same building as her father. She was provided with a simple schematic and a bit of coaching. With that, she went off on her own to build a little motor that spun a wheel, lit an LED light, and ran from the same 9 volt battery for the entire five days of the science fair.

shawnee_baughman-bedinisgShawnee won a Blue Ribbon for the science, and a special award for Best of Show, and ever since that time, the machine has been called the “School Girl Motor” or the “Bedini SG” for short.

John Bedini is an internationally acclaimed audio engineer who has many claims to fame, which include developing the first solid state audio amplifiers that actually replicated the sound qualities of the old vacuum tube models. But his favorite hobby has always been the study of advanced energy conservation methods using unconventional electromagnetic principles that most engineers have never heard of.

The Bedini SG has since taken the world by storm, spreading far and wide across the internet, and allowing countless thousands of people to build their own model and study the physics involved. Just about anybody can get one to spin, but only a handful have ever achieved a level of performance that demonstrates what some would consider “free energy.”

Many experts claim this is impossible, but actually there are many systems that produce more work than we’re required to supply, because the excess energy is provided by the environment. A good example of this is the refrigerator. This ordinary kitchen appliance typically operates with a “coefficient of performance” of 2.0, which means that twice as much heat is removed from inside than the equivalent electricity used to do it. Most scientist believe that this kind of performance is only possible with heat systems, but John Bedini and others have demonstrated these principles with electromagnetics as well.

In 1977, Ilya Prigogine received a Nobel Prize for what is basically an extension to conventional thermodynamics, which only describe how heat operates in “closed systems.” Those are systems that are cut off from any external form of energy. Prigogine’s work helped to extend our understanding of thermodynamics to include systems that are open to the environment, which slows the appearance of entropy down and allows more total work to be done than what we have to supply. That is exactly what the Bedini SG demonstrates in a simple and most elegant way.

Several years ago, A & P Electronic Media, a digital publishing company founded by Aaron Murakami and Peter Lindemann published the first ever authoritative book on Bedini’s technology. Murakami and Lindemann have collectively known John Bedini for over 45 years and both have been personally mentored by him.

Their first book outlining the basics of this technology is Bedini SG – The Complete Beginner’s Handbook, which includes all of Bedini’s own personal specifications for building his machines, as well as an in depth explanation of the science and theory behind its operation. With this book, just about anyone can build a working model.

The second book is Bedini SG – The Complete Intermediate Handbook. It digs deeper into the theory of the technology and shows how John’s circuits act like miniaturizations of systems developed by Nikola Tesla over 120 years ago. What this process does is take the high voltage spikes from an electromagnetic oscillator and charge a capacitor with them. This capacitor is then discharged into a load, such as a lead acid battery.

Engineers are normally taught to ground these spikes out so they don’t damage other electronics on an electrical line. In fact, that is what a “surge protector” is designed to do. Through experimentation, John discovered that these electrical transients have a number of unusual characteristics. One of these benefits includes the ability to charge batteries extremely efficiently, and even revive some batteries that are considered dead.

Although many engineers claim these spikes can’t charge a battery because they are just high voltage with virtually no current, there are thousands upon thousands of global experiments being conducted with these circuits that prove otherwise. And if these spikes are used to charge a capacitor and then that capacitor is discharged into a battery, even more amazing results can be had. And this is one of the methods for using electricity that Nikola Tesla developed back in 1893. John’s circuits are literally a miniaturized version of some of Tesla’s greatest discoveries.

A & P Electronic Media has now released Bedini SG – The Complete Advanced Handbook. The finale to this paradigm-shattering trilogy teaches the reader how to convert the mechanical work produced on the wheel into even more electricity, in an extremely efficient way. As a matter of fact, it is so efficient that at the recent 2014 Energy Science & Technology Conference, Peter Lindemann was able to demonstrate how to light a large bank of LEDs to a very bright level without reflecting almost any mechanical load back to the machine.

This third book also reveals many details from John Bedini’s other related technologies, some of which have never been released or explained to the public before. In that sense, it also doubles as a tribute to his tireless contribution to the field of advanced energy research over the last four decades.

LiFePO4 – Lithium Iron Phosphate Batteries

For years, the “Lithium Ion” battery has dominated the market whenever high capacity, small size and low weight were application requirements. That means, they have been used exclusively in cell phones, Tablet computers, Laptops, and most of the new high capacity portable tools. But that is not all. They are also used in the newer Hybrid electric automobiles and even the latest transcontinental commercial airliners, like the Boeing 787 Dreamliner.

Although these batteries have a very high energy density for their size and weight, they can also be dangerous if they are not charged properly. You may recall some of the stories in the last few years about laptop computers bursting into flames, and even the whole fleet of 787 airliners being grounded because of battery fires. So, behind the scenes, the battery industry has been trying to develop a battery that has all of the benefits of Lithium Ion batteries, but none of the dangers.

Over the last two years, a new type of Lithium battery has been quietly showing up on the market. In the last 6 months, this battery has started becoming available in almost all sizes and for almost all applications. This battery is called the Lithium Iron Phosphate battery, and is referred to as the LiFePO4 for short.

This new kid on the block, has a slightly lower energy density than the typical “Lithium Ion” batteries (about 14% less), but they are much safer to use than either Lithium Ion or even the standard Lead Acid batteries are. The cost of the LiFePO4 batteries are still fairly high, but the prices are coming down pretty fast at this point.

Here’s a picture of a Lead Acid battery used to start a car next to its equivalent battery in the LiFePO4 chemistry. You can see from this that the battery is about half the size and only one fifth the weight. Now THAT is a better battery!

Lead Acid vs LiFePO4
Lead Acid vs LiFePO4

But the best thing about these batteries is their safety. The LiFePO4 battery doesn’t have a liquid electrolyte, so it can’t leak or boil out to make a mess, and you never need to add water. It can be charged quickly without harming the battery, so it won’t over-heat. And best of all, there is NO FIRE DANGER like with the more common types of Lithium Ion batteries.

In fact, you may have already been using these LiFePO4 batteries and didn’t even know it. Many of the solar yard lights sold in the last year actually use these batteries. They get charged throughout the day and when it gets dark, the light comes on and runs the light until the battery goes completely dead! In the morning, the process starts over. And, this is done day after day after day for months and the battery still seems to be working fine.

That is one of the biggest benefits of these new LiFePO4 batteries – they can take a serious beating and still come back over and over! There isn’t another type of battery out there that can take this kind of treatment. Any other battery, such as a sealed lead acid type, would be on its death bed if it took that kind of abuse.

The LiFePO4 batteries also have a much higher life cycle rating than lead acids or the common “Lithium Ion” batteries. That means you can charge and discharge them many more times.

The LiFePO4 batteries are also a constant voltage battery. For example, with a lead acid battery, as you power a load, the voltage goes down little by little until it takes a nose dive. With the LiFePO4, you pretty much get the full voltage as you’re powering a load with them for nearly the entire time and then suddenly, they drop off a cliff. This is much more desirable because you get full power for most of the capacity of the battery, which you won’t get with lead acid batteries.

If you were in an emergency situation and needed a power supply for some light, a radio, a mobile phone charger, etc… what kind of battery would you want? There definitely is no comparison – the only kind of battery to have on hand in an emergency situation is a LiFePO4, no contest.

As you may have heard, Tesla Motors is creating a $5 Billion factory to mass produce “Lithium Ion” battery banks in order to make the mass production of electric cars a reality. The goal is to have a 200 miles range for the battery bank, which will actually be made by Panasonic. If they produced a Lithium Iron Phosphate battery as an option, the cars would have a 172 mile range, but the batteries would last much longer and they would be environmentally friendly.

Also, this could drastically reduce the cost of Lithium Iron Phosphate batteries, which would revolutionize the entire battery industry, not just for automobile applications, but also for back up battery banks in solar applications as well.

For quite a while now, John Bedini, a world-renown expert in battery charging technologies has manufactured the most effective chargers and rejuvenators for lead acid batteries commercially available to the public. These chargers have been shown to be able to bring about 80% of the batteries doomed for the dump back to many more years of useful service.

Unfortunately, these charging and rejuvenation technologies were never compatible with the common “Lithium Ion” batteries, primarily because of the problems in the battery itself.

Fortunately, John Bedini has created a small line of solar charge controllers made specifically for the new LiFePO4 batteries. That means that the ultimate in small-scale emergency solar systems are now available, which completely surpass any other similar sized solar energy system.

This new line of chargers is part of Tesla Chargers solar charge controller line known as the Tesla Solar Tracker 5’s. The LiFePO4 solar charge controllers are rated for 12 volt 3 amp and 12 volt 7.5 amp solar arrays. That is roughly 45 watts and 110 watts of solar panels respectively.

Metal Air Battery 80% Lighter than Tesla’s Model S Battery Bank

Metal air batteries have been around for a while, but they just don’t seem to be taking off in any significant way. Are they suppressed because they work too well?

We don’t know, but with this new Lithium air battery that is only 1/5th the weight of a standard lithium ion battery, you might think so.

Phinergy’s Lithium Air Battery

NEW BATTERY – 1% INSPIRATION AND 99% PERSPIRATION

Here is a new battery that is literally powered by sweat! With this battery stuck to your arm, it could be charging your phone while you work out, go hiking or do other physical activities.

Sweat-Powered Battery Prototype

The new battery is powered by lactate, which is present in human perspiration. It has a very low output right now and is in the “proof of concept” stage, but they’re working on increasing this.

At the moment the power is not that high – only four microwatts. But we are working on enhancing it so it can power small electronic devices.

Battery Secrets & Battery Rejuvenation

The Battery Secrets and Battery Rejuvenation presentations by Peter Lindemann are the definitive talks on lead acid battery chemistry and how to properly charge and rejuvenate them.

We have proven to be able to recover 80% of the lead acid batteries doomed for the dump AND be able to bring them back to 80% to 110% of the capacity of a new one. That’s right! We can even bring back some old used batteries to better than new condition.

Both presentations are available here: http://batterysecrets.com
