Does your towel make you levitate?

Let me talk to you about my favorite towel of my entire life, Peshtemals. But I have to let you know, we’re not going to be talking about how plush it is. It isn’t the thickest towel. It isn’t the softest towel, but it’s still my favorite towel. And it’s for a number of reasons that you wouldn’t know unless you had these towels.

  • fast-drying
  • packable
  • durable
  • stylish
  • more hygienic
  • convenient

But what makes these towels most remarkable is how much they can help you save on your home electric costs!

Peshtemals, also known as Turkish towels, or hammam towels, were created during the Ottoman Empire in modern day Turkey. They are thin cotton towels that are the perfect do-it-all towel for home use, beach use, gym/ spa, etc., and have become popular globally because of their functionality and versatility.

Peshtemals are fast drying, packable and durable. The fabric is made using 100% Turkish cotton, regarded for its long fibers and softness, spun from manually operated looms in Turkey. The cotton is tightly woven, making it strong and highly absorbent without taking up too much space. The tightly spun fibers help repel sand and earth easier than other fabrics making it perfect for beach days or picnics. Their stylish designs make them perfect decorative pieces and furniture covers as well.

When you’re visiting someone’s house, the guest towels are sometimes the thickest, plushest towels, too thick to be useful. You wouldn’t take a thick plush towel to the swimming pool or the beach and put it down in the sand because it would pick up a lot of sand and grime in those thick plush fibers.

You’re already aware of a variety of towels and that certain towels serve certain purposes. Towels can be made of a variety of fabrics including cotton, cotton polyester blends, linen, bamboo, and synthetic microfibers. Cotton is common because it is soft and absorbent, linen is known for its durability, bamboo is prized for its sustainable softness, and microfibers are known to be quick drying.

Peshtemals are more hygienic

Doctors recommend that when drying ourselves off we pat ourselves dry rather than rub. With a plush towel, you can rub the thick sock fibers over your skin with some force to it. But you might not do that with a thinner towel because it might scratch your skin. If you’re not wanting to be abrasive, you would pat.

Doctors also recommend that we should be washing our towels after each use because dead skin and bacteria collect on the towel and grow when it’s hanging on the towel rack. We may be reusing the plush towel for days in a row and then try to dry it out between the days and that doesn’t work because it introduces new bacteria colonies to the skin. So instead of going that way and reusing thick towels, use these thin towels and wash them after each use – you can fit 2 to 3 times as many peshtemal towels in the washer!

Peshtemals are so convenient

You can take it anywhere! For example, in your carry on luggage, you can pack for about three or four days of clothes and towel for each day. You wouldn’t be able to fit four traditional bath towels and have any room left for your clothes. But you can take a peshtemal towel with you because it’s very lightweight. In fact, when I travel, I might take a whole week’s worth of peshtemals in my bag because I’m a swimmer. So I might swim two or three times on that three or four day trip. I might take four towels and clothes for three to four days, all in one carry-on bag. And you just can’t do that with any other towel.

Utility Cost Savings

Understanding your energy profile is critically important for being able to take control of your energy independence, so that you don’t have to buy too much solar or too much battery to get to your goal, and your energy profile is affected by usage such as washing your towels.

I’m sure we’ve all experienced over loading the washer with thick, plush towels to the point the spin cycle stops working and the towels are left just sitting in still water. We’re forced to run another wash cycle and sometimes the final spin cycle doesn’t ring out enough water and then we have to leave them in the dryer longer, increasing energy costs even more!

Plush towels increase the electric bill more, especially at times of the year when the solar power isn’t producing as much. If you’re running all this extra power to dry your laundry when it didn’t need to be that wet anyways, there’s an incredible amount of savings in changing your towels.

Instead of three plush towels, you can now wash up to 15 peshtemal towels in one load and the washer will not be overloaded. And when it spins dry, it’ll be much drier. And then the heat pump clothes dryer doesn’t have to go through as long a cycle.

Makello Research Assistant in UCSD ESYS Capstone

AuroraSolar solar design model energy analysis irridiance

I was going into my last quarter of undergrad at UCSD when I started interning at Makello. The internship was part of my Senior Project, and I enjoyed working with a diversely skilled team.  I worked with people with experience in many fields including software/electrical engineering, solar installation, non-profit organizations, management experience, and GIS systems all united by a common goal: clean energy.

I recently completed my B.S. in Environmental Systems and Earth Sciences with a minor in Marine Sciences. I am pursuing a career to combat climate change to preserve our planet as we know it, but there is also a part of me that feels a societal obligation to help elevate the standard of living (if they want it) for people who do not have equal access to opportunities such as education, community resources, healthy foods, etc. I believe we live in a society to take care of each other, and generally, disadvantaged communities could use additional resources, so I was excited to work with a company that works closely with non-profit organizations, especially non-profits in disadvantaged communities, such as Groundwork San Diego. I am thrilled to be in a position, right out of college, where I can help combat both social and environmental justice.

During my internship, we attended many events as both attendees and presenters, sometimes with Groundwork San Diego or our solar installation team. Examples of events were community activities, such as organized runs or home and garden shows, where we would provide information about electric vehicles and solar. We also attended car shows and electric vehicle focused events to stay current with new electric vehicle technology and to help explain their benefits to the public.

Part of my initial training was how to use solar design and cash flow analysis software, the site survey measurements and the customer’s goals to determine the Optimal System Size. I grew up doing home remodels and renovations during summers, so I enjoyed visiting different homes and seeing different styles of architecture and landscaping throughout San Diego. It was cool to see some existing solar arrays that customers had already installed too. It was also nice to be able to put a face to the customers whose proposals we were working on. 

Working on customer proposals and site surveys was my favorite part of the internship because it was a combination of computer design and modeling, hands on physical labor, and critical and analytical thinking. I still enjoy the same work, but now my Research Assistant position is 100% remote because we follow CDC guidelines to keep ourselves and our community safe. We used Makello’s software model to create the custom trade-off study proposals for each customer and automatically generate the correct price, ethically, without sales gimmicks.

Makello’s honesty and knowledge of energy efficiency, utility rates, solar power, electric vehicles, and battery storage, as well as assessing the needs of individual customers and their families, is what drives the high win rate with customer proposals.  On more than one occasion, customers wanted to purchase more solar than they needed, or wanted a battery because they believed it would increase cost savings. Using Makello’s model, our team showed that, in fact, a smaller solar system is needed if replacing inefficient appliances, or changing the times the appliances are in use.

I was excited to work on a diversely skilled team to create community pages for our website. We ended up creating a valuable tool with important information and graphics for San Diego communities. The pages had GIS Maps that displayed information on a variety of issues such as air quality, electric vehicle charging station locations, rebate eligibility, etc. We also included a list of different rebates and incentives for solar, electric vehicles and battery storage as well as information as to why they are beneficial to the environment and how they can save money.

Apple on Wheels

Tesla has become the new standard for modern vehicles.

Apple, under Steve Jobs’s leadership, revolutionized the cell phone industry and defined the smart phone as we know it today. Tesla is positioned to do the same for the automotive industry.

Tesla has become the new standard for modern vehicles.
A gold Tesla Model 3 symbolizes the new standard for modern day vehicles.

In 2012, Tesla reinvented the electric vehicle with the Model S and captured people’s desire for clean, sexy, and powerful.

Electric vehicles existed over a hundred years ago, but they failed to succeed in the consumer market. There were also electric cars in the market in the early 2000s, but they sacrificed speed and range to be environmentally-friendly. What Tesla did differently, was create a battery electric vehicle with a futuristic design. The speed and versatile functionality made simple by advanced technology, the durability that you can depend on, and the potential to improve with time. In a way, this is roughly the recipe for the first iPhone, but on wheels instead. 

In 2008, a Tesla Roadster was ruthlessly mocked on Top Gear, the world’s most popular car show. Yet today, if you look at the Monthly Plug-In EV Sales Scorecard [2], you will find that more Teslas are sold in the U.S. than all other (42) Plug-In Vehicles combined. With Tesla finally becoming profitable in Q3 of 2018, Tesla’s stock has become one of those investments that many people wish they had made.  However, deep down, I have always had doubts toward Tesla’s success. 

In February, I decided to visit the “Meet – Greet – Share” event hosted by the San Diego Tesla Club at the Fashion Valley Mall Superchargers, to see if Tesla really is a challenger for the ICE (Internal Combustion Engine) car industry. The gathering of over fifty Teslas and over one hundred Tesla owners, employees, and supporters was impressive.

I enjoyed seeing a Roadster up close, even more than the one sent to space (see that one here).  

Electric vehicles accelerate fast and are fun to drive.
Tesla Roadster. I guess the people at Top Gear weren’t impressed with the paint job? Well, a fast car should look fast!

It’s funny how dozens of Tesla owners just came here to plug into the Superchargers, but then found out about the meeting and stayed! And these Tesla owners, unlike how some are portrayed on the internet, are great people too. They welcomed a non-owner, like me, and were happy to share how their Teslas impacted their lives. Tesla owners are passionate; many said, “Once you got a Tesla, you can never go back [to any other Internal Combustion Engine cars].” 

Contrary to what some harsh comments suggest on the internet, many of the Tesla owners are interested in seeing what the EV market has to offer and how various products have improved ever since Tesla helped to grow the EV market.

Tesla has inspired many technological advancements.
Tesla Employees and EV Enthusiasts come together to appreciate technological advancements.

The Tesla employees were friendly, too.  Signing up to test drive a Model 3 was quick and easy. Bobby, the Tesla representative, was very thorough and professional in his explanation of the Model 3’s features. 

The credit card-like car key means you can slip it easily in your wallet or purse instead of getting it scratched on the key chain. The Model 3 achieves efficient usability through the 15 inch touchscreen and the two sphere controls on the steering wheel that provide all of the customization for the driving experience. 

The experience enters a new dimension once you start driving. The lack of engine noise provides a sense of peace and calm. The car starts instantly and can drive immediately, without needing to warm up. On a hot day, the cabin cools within seconds due to the seamless full width vent. 

Once we got to the open road, Bobby encouraged me to put my foot down on the accelerator pedal. After stepping gently on the pedal several times, I said to him, “I am gonna give it the beans, you ready?” Bobby said, “Yeah.” I floored the accelerator pedal. Within 3 seconds, the silence of the sudden acceleration was interrupted by a warning beep for going over the 40 mph speed limit. In the process, Bobby almost spilled his coffee (good thing there was a lid). When the light turned green at the next intersection, I did it again. None of the other cars had moved by the time we were through the intersection.

Now, following the launch of the Model Y, there really is something “S-3-X-Y” in Tesla’s lineup. The excitement and innovation that Tesla products offer makes those of us who love cars, love them even more, and for those who never cared, can now find driving more enjoyable than ever. 

Progress works in unique ways, even when it doesn’t happen easily or overnight. Not all of us can recognize the next big thing when it comes along, and some of us might even reject it at first. That’s why despite the challenges laid ahead of Tesla by profitability, layoffs, the stock market, and even the SEC, Tesla’s role in the history of automobile development is undeniable.

Today, we are at a turning point of automotive history, similar to when the early cars displaced the use of horses for transportation.  It is our job to embrace the future that belongs to electric vehicles. When we face our grandchildren decades from today, we can proudly tell them, “We weren’t the ones crushed by the giant wheel of history. We were the ones who rode on it. In fact, we were in ludicrous mode on a Tesla.” 

After the event ended, I test drove the MINI Countryman SE All4 featured in my last blog article (which you can read more here). The Countryman’s 0 – 60 mph time of 6.7 seconds isn’t slow at all, but it was not even close to the acceleration and thrill of driving the Model 3.

(See Track 6, Section 6-9-2 ‘Distributed Generation and CCHP’)APPLICATION OF AN ADVANCED SIMULATION MODEL TO A MICRO-CHP ORC-BASED SYSTEM FOR ULTRA-LOW GRADE HEAT RECOVERY

Davide Ziviani, Asfaw Beyene¹, and Mauro Venturini²This paper presents the results of the application of an advanced thermodynamic model developed by the authors for the simulation of Organic Rankine Cycles (ORCs). The model allows ORC simulation both for steady and transient analysis. The expander, selected to be a scroll expander, is modeled in detail by decomposing the behavior of the fluid stream into several steps. The heat source is coupled with the system through a plate heat exchanger, which is modeled using an iterative sub-heat exchanger modeling approach.

The considered ORC system uses solar thermal energy for ultra-low grade heat recovery. The simulation model is used to investigate the influence of ORC characteristic parameters related to the working medium, hot reservoir and component efficiencies for the purpose of optimizing the ORC system efficiency and power output. Moreover, dynamic response of the ORC is also evaluated for two scenarios, i.e. (i) supplying electricity for a typical residential user and (ii) being driven by a hot reservoir. Finally, the simulation model is used to evaluate ORC capability to meet electric, thermal and cooling loads of a single residential building, for typical temperatures of the hot water exiting from a solar collector.

DEVELOPMENT AND VALIDATION OF AN ADVANCED SIMULATION MODEL FOR ORC-BASED SYSTEMS
Davide Ziviani, Asfaw Beyene¹, and Mauro Venturini²Low-grade heat recovery from solar or geothermal energy may be an eco-friendly resource for electric and thermal energy recovery. The Organic Rankine Cycle (ORC) is one of the main candidates to exploit low-temperature heat sources, otherwise difficult to access using conventional power generation systems.
In this paper, an advanced thermodynamic model of an ORC is developed, with the final aim to optimize ORC conversion efficiency, especially for micro-CHP applications. First, a thorough review of issues related to ORC system modeling is presented by analyzing the state-of-the-art experience and advancements. Subsequently, an advanced simulation model is developed, by taking advantage of all the key characteristics of the models presented in the literature. The simulation model is developed in Matlab®/AMESim® environment, which allows system modeling both for steady and transient analysis. The heat source is coupled with the system through a plate heat exchanger, which is modeled using an iterative sub-heat exchanger modeling approach. A scroll expander, modeled in detail by decomposing the behavior of the fluid stream into several steps, is used to extract the useful work.
Finally, model predictions for the evaporator and the expander are validated against both numerical and experimental data published in literature. The simulation model of the entire ORC system is also validated against literature data taken on a test bench.
