Energy United & Advanced Energy – EV Workshop Presentation

On June 5, 2015 I spoke at the Energy United / Advanced Energy Electric Vehicle Workshop about my family’s experience of driving electric for the past 3 years.  The workshop was great, there was a BMW i3, a Tesla Model S, my Volt, an electric dune buggy, and an electric bicycle.

June 5, 2015 Presentation

Download a copy of the presentation to view the slides. In short it has been a very rewarding three years. We had the first Nissan LEAF in Western North Carolina, delivered in November of 2011. Our first charging station was provided by Duke Energy as part of their Charge Carolina’s EV Charging Station pilot. The charging station is still being used every day.

My wife and I both traded our LEAFs in on Chevrolet Volts in 2013. I very much wish we had started out with the Volts. Having said that, we appreciate them much more coming from the LEAF experience.

Since the last upgrade to our solar PV, we are able to charge both cars and run the house pretty much offset by solar energy. In fact, during the month of May 2015 we produced 48 kWh more than we used to run the house and two cars.

March is National Eye Donor Month!

March 2015: National Eye Donor Month

 

 

 

 

 

 

As a recipient of two corneal transplants I think of my donors every day. Please consider becoming a donor to give the gift of sight to someone.
I would be blind and unable to maintain this site without such an unconditional act of love by two people and their families.

NC Renewable Energy Credits Available for Solar Set-Aside

NC Renewable Energy Credits Available for the Solar Set-Aside

We have two Renewable Energy Facilities registered in the NC-RETS Renewable Energy Portfolio Tracking System.  Both facilities are located inside North Carolina and produce power from certified and calibrated metered systems.  I will consider selling solar PV and metered solar thermal RECs to North Carolina Power Companies, Co-Ops or municipalities who are also registered in the NC-RETS system.

Follow this link ( https://portal2.ncrets.org/myModule/rpt/myrpt.asp?r=204 ) to see a current listing of the NC-RETS Bulletin board, currently about 25 RECs are available for transfer / sale.  Look for facilities GEN259 and GEN266 .

Welcome!

Welcome to Ken Clifton’s blog.

If you are a student you will be most interested in the “teaching” category content. Please feel free to explore the “About” and “Resume” links at the left.  If you are interested in RECs please see the renewable energy credits link.  The Salisbury Post did a front page story on our solar PV facilities that ran on February 8, 2011.

We are excited about renewable energy! This site is run on solar generated electricity.  We have solar PV and solar thermal renewable energy facilities approved by the State of North Carolina at our home.    See the renewable energy link for more information. If you are interested in biomass or CO2 neutral home heating, please read the Salisbury Post newspaper article published on February 11, 2007 for more information.  My presentation made to several groups on biomass is also available.

Thanks, and I look forward to working with you during the Spring 2015 semester!  Please consider becoming an organ donor.  I have vision to maintain this site and work thanks to two corneal transplants.  Without those transplants I would be blind.

Another Step on the Journey

On October 28th I received the gift of sight from a person who selflessly donated their eyes so that others might see. Kat and I are gearing up for the next transplant surgery. We are very thankful for the prayers of so many. A simple “thank you” is just not enough for the many expressions of thoughtfulness made in so many different ways during this difficult time.

My computer time continues to be very limited as I am recovering, but Kat has been wonderful to read many messages to me. Here is the text of a letter I wrote to the family of my eye donor, the identity of whom I will never know. This letter was mailed to the Eye Bank last week:

Subject: Please Convey My Sincere, Heartfelt Thanks

Dear Sir/ Madam,

Words cannot express the difference your loved one’s gift of vision has made in my life, and to my family. My entire life I have had useful vision in only one eye due to a birth defect. Beginning in 2007 I began to lose that vision due to a corneal disease called Fuch’s Corneal Dystrophy.

Fuch’s disease not only causes loss of vision, but in its later stages extremely painful blisters can erupt on the eyes, causing severe pain. For the last six months I have suffered from multiple blisters on both eyes. The pain and loss of vision are a terrible combination.

This October, at the age of 54 my vision was so bad I had to stop my college teaching due to the loss of vision. I could no longer work to support my two young children, aged 7 and 13. This was a very stressful time for my family.

By the grace of God, I found a very gifted surgeon at the University of Alabama, Callahan Eye Hospital. Dr. Parker was able to perform a transplant for me on October 28th that not only restored my vision to 20/20, but also took away the terrible pain in one of my eyes. Your loved one’s gift changed my life.

I am scheduled to receive another corneal transplant soon. Our hope is that it will eliminate the pain and restore some vision in my other eye with the birth defect. That eye also has multiple blisters from Fuch’s disease.

Thanks to the caring donation of the eyes of a kind, selfless person I am able to see. I can’t describe the powerful explosion of color, beauty and light that I have seen this week. When we returned home I was able to see the faces of my two children again. In January of 2015, I hope to return to teaching at the Community College to continue making a difference in the lives of hundreds of students.

Please know that your loving donation of sight has made a HUGE difference, and has touched many lives.

With Sincere, Heartfelt Thanks

New Challenges, But Not My Last Post

The last few months have been very difficult. I have struggled from one day to the next in a good bit of “extreme” pain as my vision is slowly taken away by Fuch’s Corneal Dystrophy. Much of my limited computer time is done with the help of a magnifying glass or the accessibility tools. Last week I turned over all my Fall classes at RCCC to other professors.

I remain steadfast in my faith that God has directed me to a wonderful transplant surgeon. My hope is that soon I will once again be able to “see” my children grow up for a few more years and to see many more happy moments with my wonderful wife Kat.

Even when faced with the vision challenges we added another 3 kW of solar in the summer of 2014. What stronger statement could I make than to undertake a solar project while in the midst of a potentially life-changing event? Make no mistake, I had a laser-like focus to ensure the project would provide continuously increasing benefits to my family for many years to come.

Lastly, I want to say thank you to all my students of the past 23 years! I hope that each of you will continue to be life-long learners. The best things in life come through faith, perseverance and hard work. I know we worked hard together in my classes.

Battery-Less Wind Turbine and Micro-Inverter

Primus AIR-40 Wind Turbine

Primus AIR-40 Wind Turbine

I have been interested in small wind turbines for some time. But, not because they are practical in my area from a power production perspective.  My interest is that I could use the wind turbine’s production to reduce the demand-charges imposed by our utility.  With our time-of-use service, the power company imposes an additional charge for each kW we draw during the peak rate periods.

While a wind turbine’s payback in my area is pretty long based on power production, if it reduced demand charges that is a different matter.  In fact a wind turbine might pay for itself very quickly considering that when we don’t have good sun, we usually have wind.

Another detractor regarding the wind turbines is the added complexity of a battery bank and dump loads.  The cost and maintenance of a battery bank just did not interest me. All that changed yesterday when I found a Masters Thesis by Christopher Eldridge (2011) at Kansas State University.

In his thesis, Eldridge experimented with using an Enphase micro-inverter, and a Primus AIR Breeze 160 watt wind turbine without a battery bank.  His thesis is very interesting.  I expect to be looking for some capacitor boards, and power NFETs very soon.  Mr. Eldridge’s work is much appreciated and definitely changed my perspective.

Thoughts and insights from other solar producers are welcomed!

Here is the information on his thesis:

NISSAN DC Fast Charger in Salisbury, NC

As of today, NISSAN electric cars with a quick charge port can charge up to 80 percent in 30 minutes here in Salisbury, NC.  The fast charger should really help folks driving I-85 between Greensboro and Charlotte since we are right in the middle. Kevin Murphy of Ben Mynatt NISSAN sent me this photo today of the new DC fast charger that is now operational:  click to view status .
