PART 1 WIND POWER PROGRAMS – RPM AT MPH.wmv

THIS IS A VIDEO THAT I WROTE TO FIGURE OUT HOW MANY RPMs THE WIND TURBINE WILL SPIN FREELY WITH NO LOAD ON IT IN THE GIVEN WIND CONDITIONS IN A CERTAIN AREA. THAT WAY I WOULD KNOW WHAT VOLTAGES TO EXPECT IN THE AVERAGE WINDS OF THAT AREA. AND IF THE WINDS ARE LOWER FOR THAT AREA I COULD EITHER SHORTEN THE PROP FOR A LITTLE MORE RPMs. OR I COULD JUST ADD MORE MAGNETS, OR REWIRE THE OUTPUTS. ONE OTHER ADVANTAGE TO THIS PROGRAM IS IF I KNOW THE EVERY DAY AVERAGE WIND SPEED , I CAN DESIGN THE ALTERNATOR TO GIVE ME A DESIRED OUTPUT. TOGETHER WITH THE OTHER PROGRAM THAT IS PART 2, I CAN FIGURE OUT THE EXPECTED POWER OUT AND DETERMINE THE PROP SIZE AND THE RPMS NEEDED TO GET THE JOB DONE, AND THE DESIRED WIRE SIZE. ALL THESE FACTORS ARE VERY IMPORTANT IN THE DESIGN OF A WIND TURBINE FOR YOUR AREA. THIS IS A GIFT TO YOU MY VIEWERS AND I HOPE YOU FIGURE OUT HOW TO GET THE MOST OUT OF IT. I WILL PROBABLY OFFER THE FULL 2 PROGRAMS TO DOWN LOAD IF I CAN FIND A SITE TO PLACE THEM AT. THESE PROGRAMS ARE IN GWBASIC LANGUAGE. THERE IS A SITE CALLED FRIENDLYRAT.COM WHERE YOU CAN DOWN LOAD THE BASIC COMPILER TO RUN THESE PROGRAMS. SORRY I LEARNED TO PROGRAM WHEN I WAS GOING THROUGH ROBOTICS AT TEXAS STATE TECHNICAL INSTITUTE IN SWEETWATER/ROSCOE CAMPUS, A DIVISION OF A&M. THIS WAS WAY BACK IN 1982 OR 83. HELLO COMMODORE 64 AND TRS 80s AND TI 99s THE CUTTING EDGE OF TECHNOLOGY FOR THE 80s , AND HELLO BASIC PROGRAMMING. THAT WAS WHEN 64 MEGABITES WAS REALLY COOL. BUT THE BEST THING IS THAT

Glenn Pew interviews Eric Raymond. Eric has been flying his battery launched solar assisted sailplane since the late ’80s. He knows the road to progress doesn’t come as bolts of lightning in time but through years of small steps. Glenn Pew caught up with Eric to learn about Sunseeker the Solar Impulse project and more… www.glennpew.com
