How to make a Solar Panel – Wiring, Soldering, and Cell Layout – Explained Simply!

Published January 11, 2015 in Sun Water Wind Energy - 0 Comments

This “how to make a solar panel” video shows how to connect everything together including all wiring, soldering and cell layout (using tabbed solar cells). Full easy instructions. if you are using “untabbed” solar cells watch my video on “Solar Cell Tabbing”. (tabbing is very easy to do). items can be bought as a kit on ebay. for about $48.00 you can get 40 solar cells, tabbing wire, bus wire, flux pen and even blocking diode. i used lead free rosin core solder from harbor freight. cost about $2.50. soldering iron is just a basic 30 watter. the third (and final) video will show how to encase/enclose the panels in either a plywood box or metal framed case.

Extreme Weight Loss – “James” (Season 1 / Episode 4)

Published January 10, 2015 in Weight Loss Secret - 0 Comments

James is a 26-year-old man who had hopes of becoming a pro football player. Now he gets winded just walking down the street to the lamppost outside his home. His abdominal hernia can’t be fixed because it’s unsafe for a person of his stature to go under anesthesia. James has been engaging in late night workouts so that no one else will be around to see him. It’s a start, but he needs help. Well, help is on the way.

Chris Powell surprises James at one of his 2 a.m. gym sessions. They jet off to Los Angeles for boot camp and the initial weigh-in which registers James at 651 pounds. There’s some combativeness during the first workout, with James making demands for water. Chris won’t give him any until he finishes the fight. When James returns home to Texas, his home has been transformed to an environment conducive to weight loss. His bedroom is now a home gym.

James is tasked with losing 150 pounds in three months. If he does this, Chris will reward him with a special bike that will hold his weight. James drops 51 pounds over the first 30 days. He’s getting support from his family, with his mom being his biggest advocate. On day 50, Chris challenges a stubborn James make a roundtrip run to and from that pesky lamppost. He makes it with a few seconds to spare. At the 90-day weigh-in, James is down to 497. Time to go for a bike ride!

The next phase involves losing 80 pound over three months. James works hard right up until the day he’s admitted to the hospital after suffering from heavy fevers and shortness of breath. This illness threw a monkey wrench into his workout regime. At the next weigh-in, he’s down to 486. That means he only lost 11 pounds.

James is introduced to former Dallas Cowboys stars Nate Newton and Michael Irvin. Why? Well, for his milestone, James plays a little football under their watchful eyes. The workout impresses Michael Irvin, as well the men James plays against. Then it’s time for Phase Three. Chris asks James how much he wants to lose this time around. He sets the goal of 30 pounds a month to get back on track.

As day 270 rolls around, James heads back to Los Angeles for the next weigh-in. Chris realizes that his client is a completely different person. His target weight was 396. James comes in at 394. That’s 257 pounds lost in nine months. Three more months to go!

At the end of a grueling year, James is brought to the site of Super Bowl XLV where a cheering crowd awaits. His transformation is amazing. At the final weigh-in, James comes in at 338 pounds. That means he lost 313 pounds in one year. As a reward for this remarkable achievement, Chris gives James two tickets to the big game. You could say this entire experience has been a total touchdown. Way to go, James!

Extreme Weight Loss – “Jeff and Juliana” (Season 4 / Episode 13)

Published January 10, 2015 in Weight Loss Secret - 0 Comments

Jeff and his daughter Juliana have a strained relationship. Juliana was born to Jeff and his wife late in life (her two siblings are more than a decade older). As a result, Juliana struggled to connect with her father, and often felt ignored and overlooked. Now 15, Juliana can no longer keep her resentment toward Jeff buried inside. Realizing he needed to be a better father and role model to his daughter, Jeff wrote a letter to trainers and transformation specialists Chris and Heidi Powell asking for help.

At 423 pounds, 55-year-old Jeff is 200 pounds overweight. 265-pound Juliana is bullied and ostracized at high school over her size. Chris and Heidi team up to try and help repair the strained relationship between father and daughter while challenging Jeff and Juliana to lose over 330 pounds together.

Along the way, Chris and Heidi make some of Jeff and Julian’s dreams come true. Jeff gets the chance to meet and work out with his favorite football team, the Denver Broncos-including Pro Bowl stars Terrell Davis and Karl Mecklenburg, plus current star Demaryius Thomas and former Bronco Eric Decker (who is now a member of the New York Jets). Meanwhile, Juliana realizes her lifelong dream of riding roller coasters with her dad at Disney World, where they also run a half-marathon together.

However, their journey doesn’t always go smoothly. After noticing that Jeff and Juliana aren’t losing as much weight as they should be, Chris and Heidi place them under surveillance, and discover that both father and daughter are cheating on their diet and exercise plans. Also in the episode, Rocco DiSpirito shows Jeff and Juliana how to make double chocolate cookies that taste great and have fewer than 100 calories each.

Jeff and Juliana’s yearlong physical and emotional journey together is an inspiring story of the importance of family, love and perseverance.

Extreme Weight Loss – “Brandi” (Season 4 / Episode 7)

Published January 10, 2015 in Weight Loss Secret - 0 Comments

As a child, Brandi fell in love with beauty pageants after watching them on television with her mother. A born performer, she took ballet plus tap lessons and competed in pageants for years. By the time she was 12, Brandi weighed more than 250 pounds, and comment cards from pageant judges told her over and over that she was too heavy to compete.

Crushed by the criticism, Brandi quit competing and continued to put on weight throughout high school and well into her 20s. After reaching 329 pounds, she wrote a letter to trainer and transformation specialist Chris Powell asking him for help.

At 29 years old, Brandi is a freelance makeup artist in the beauty pageant world. Though she says making others feel beautiful makes her feel beautiful as well, she still secretly wishes to be one of the beauty queens standing on stage. Brandi gets a once-in-a-lifetime opportunity to meet and work with Miss America 2014, Nina Davuluri.

Brandi becomes Chris’ first client to compete in a Half Ironman, under the tutelage of Ironman competitor and Sugarland guitarist Thad Beaty. The Half Ironman Triathlon is a brutal challenge that forces her to swim, bike and run a combined 70.3 miles in under eight hours. Also, celebrity chef Rocco Dispirito teaches Brandi how to eat healthier versions of her favorite meals in order to achieve her goal of losing a pound a day.

How to Make Solar Cells using Transistors (2N3055)

Published January 9, 2015 in Sun Water Wind Energy - 0 Comments

It’s easy to cut open a power transistor like the 2N3055 to expose the NPN silicon material inside to make a solar cell. When exposed to sunlight, or household lights, it conducts electricity. The N-type and P-type materials work like a solar cell. The best way is from the Base to the Collector though from both the Base and Emitter combined and then to the Collector also works well. The voltage and current aren’t much but with just a few of them in series you can power a small 1.5 volt calculator.

The past two years has seen the uniquely rapid emergence of a new class of solar cell based on mixed organic-inorganic halide perovskites. Although the first efficient solid-state perovskite cells were reported only in mid-2012, progress was extremely rapid during 2013 with energy conversion efficiency reaching a confirmed 16.2% at year-end, increasing to a confirmed 17.9% efficiency in early-2014, with unconfirmed values as high as 19.3% claimed. Moreover, a broad range of different fabrication approaches and device concepts is represented amongst the highest performing devices with this diversity suggesting performance is still far from fully optimised. This report briefly outlines notable achievements to date, describes the unique attributes of these perovskites leading to their rapid emergence and discusses the challenges facing the successful development and commercialisation of perovskite solar cells.
