"That slewing bearing will be very expensive!"

"My experience is that after the 2008 elections, research funding for NREL projects was greatly reduced. Not much support there! My current project is entirely private funded. We as an industry need to be self sufficient and not be dependent upon the…"

"The difficulty with the US wind industry is that there are some real-world "challenges" with the existing technology. The biggest is that marketing/sales want the turbines to be less expensive and this causes the engineers to reduce safety…"

"No sir not a lot but I'm an engineer by trade. Had my own company for years building and designing semiconductor production equipment."

"Do you have any experience with electrical interconnections that are needed for renewable (wind) projects?"

"Structurally, what size of poles will be necessary to withstand the wind load? Small turbines are not so much a problem, but as you get bigger, it takes more to support. I'm also finding that to get the torque, we had to go to a larger…"

"How is the torque/power transmitted to a generator? Is it through the 3 shafts? How big do you think you can get? Can you get to 10 or 20 kW?"

"Interesting concept. We looked at a similar idea,but ran into noise and vibration issues. You can hear the contact of the wind capture plates hitting the stop during the video. If you increase the size too much, that noise becomes a lot of…"

"Concerning the Hydraulic pump windmill: All manner of power conversion (from wind to mechanical to electrical) has a certain amount of inefficiency. By converting the mechanical (rotating blades) to hydraulic, transporting that hydraulic power,…"

"Ross, We have a concept that we will be testing in the next 2 weeks. At this point, it is being kept (somewhat) secret. But, once the patent applications have been filed, my clients should allow me to show everyone. I like the variable speed drive…"

"Thank you! Please call 978-930-2110 or email alanlefavour2112@hotmail.com if you have any thoughts. I can envision 100m plus height. The force on a sail is cubed to the speed of the wind"

"Interesting concept - that wind sail/turbine. I wonder what happens at high wind speeds. Is the sail able to "slough off" some of the wind to keep from being damaged?"

"It is very interesting reading our comments and ideas! I am in the process of testing a 'non-traditional' type of wind turbine and as soon as we are allowed to publicize pictures, etc. I'll put them here (if possible). Our project is…"

"The primary reason all the hardware is on top is due to cost and not wanting to work with the unknown. Gearing/generators are tried and true - even if there have been problems. Trying to qualify a different method is expensive. Finally, there is the…"
