Great wind resource review. This has helped me immensely as I've studied this in college, but it's been some time since I've needed to have the knowledge on hand. Thank you Dr. Gardner!

the presentation is very informative and useful, thanks so much John!

Hello Professor, I have Stephenson I six bar mechanism. Which approach would be better to solve the theta values on it ? I have theta2 value and torque on mechanism with the link distances

Thanks John

can you explain why we need 2 functions here? it makes sense that for two unknowns we need two equations. but to find the roots of one function from R^2 to R, why do we need a second function? what is this second function? is it somehow related to the original function?

Okay I know this is from 9 years ago but I'm hoping by some miracle you can help me today. When I do the spider chart and I change one of the variables, a portion of the gradient for another variable changes completely (goes from positive to negative gradient) and I can't understand why or what that means. I really hope you see this, it's driving me crazy!

Thanks for the explanation, it really helped a lot

Thanks boss

Just one question: is there the possibility to meet the load with the configurations that Homer creates without write in input which one to simulate manually? I mean, maybe the best configuration could be one that I didn't choose to simulate in the search space. Thank you

Superb introduction, thanks so much. One small thing: I noticed that in the summary bar of the first wind rose you show (from Wikipedia), the %s add up to only around 97%. I'm guessing the rest might have been gusts exceeding the maximum speed which the rose cover.

Um

the HOMER tutorial

Hello Professor, 2nd input is velocity or acceleration. I am confused, Could you please elaborate it. Thanks!

Excellent video

How to calculate cooling load and heating load using hommer software?

is it $155,902.36?

Thanks for disseminating your excellent knowledge. This helped me a lot.

Hi. I'm testing HomerSIP, my scenario is several asterisk, I built a VM just for HomerSIP, and I configured my asterisk to send data to HomerSIP, but I can't find how I can configure HomerSIP to receive this data. I am Brazilian, and looking for a configuration manual, which helps me in a practical way. where can I find ?

Thanks John

Does this still apply if the pivots for the crank and follower are offset? Is a translation to a global coordinate system needed?

Thank you Mr. Gardner

THANK YOU. But, how I can download this?

Hello John , please how can I get crack for this program

Thank you! Dear Professor John, your videos about HOMER are just so helpful!

can you make an pv*diesel*battery plants model connected to the distribution grid

Thanks for the video, It was really helpful.

good work

Great stuff, really helped me understand how this method works. Thank you! Are you familiar with how to cite an instructional video like this?

Could you show the function commands into excel please? This is incredibley frustrating. The concepts are clearly understandable but as students we are not taught the specific inputs for excel. Skipping to the final output of the graph doesnt help the badly needed technically understanding.

Hello John I am currently writing my Masters thesis and your videos on HOMER have been incredibly useful! At the end of this video you are about to talk about unmet electrical load and capacity shortage but your computer crashes. This is an area in my results I am struggling to make sense of. It would be much appreciated if you could explain a little about them? using the example you have in you video would be fine.

Nice video, Is very important to install the barometric and temperature sensors in order to calculate the air density of the site, and then to select the best turbine according to its power curve.

Thank you for sharing this John. I was wondering, would it be possible to know more about how to compute the LDC in Matlab?? I see that's the program you use in the video. Thanks again!

What book is this based on?

Dear sir, I used homer and it appeared "An invalid argument was encountered. " Can you tell me how to solve this problem?

Thank very helpful

The graph showing Estimated US Energy Use in 2010, you pointed wrong about solar. In that case, only 0.01 (no unit) of solar were used to produce electricity and 0.10 were used to residential heating (solar thermal technology). When renewables that don't convert fuels into electricity are represented in figures for households, they are represented as final values. i.e. all the losses through the renewable system were already taken into account.

whats the book you are referring to ?

Good Evening John! You have literally made me understand differential equation to Simulink block diagram conversion within these few videos. Thank you very much. I would like to know if you perhaps have any resource regarding the position correction via either PID control or some sort of feedback element? I have been struggling for hours to get the position of the ball to stay at the 0.007 m position.

thanks for the detailed explanation

Very good explanation and very informative. How I wish that the voice audio is much better.

Excellent video, tks

it is a beautiful and useful explanation so thanks

bonjour je besoin des conseil sur le thème système hybride sur la ville d'ORAN-Algerie Comment compléter les information de Primary Load et solar resouse please

Can you write similation including Wind turbine, Solar panel, load, and genertor? Thanks.

Thanks John

Thank you!

Pretty simple explanation_Thank You,
