How many hoops did they have to jump through to get permits for zoning, excavation, disruption of "wetlands", don't step on this beetle, utility easements, etc. These are the real cahllenges to a project of this type. The technical part is simple!
I agree that there needs to be support and commitment at the micro level. The challenging economic climate of the last few years has definitely fanned the flames of the local movement and a do-it-yourself mentality. Perhaps that will translate into more people attempting projects as ambitious as this one.
What wasn't clear to me is if they generated single phase or three phase power. Why the three motors? 15hp is about equal to 20kW, so any one motor could have been a generator. Can anyone fill in the blanks here?
Also, I'm curious what prompted the report--it does read suspiciously like an Automation Direct ad....
@letsthink: I agree with you that the numbers don't add up. If 40 cubic feet per second of water (18,000 gallons per minute) falling 10 feet generates 20 kW, then 2 gallons per minute falling 2 feet should generate about 1/90,000 as much power, or 0.2 W. Maybe you could make a LED light up with this.
If renewables are going to make a significant impact, a certain percentage of the power and a certain percentage of the storage will have to happen on the micro level. This is a great effort and it's a perfect example of what can happen at that micro level.
I agree, Rob, this sure eliminates the storage problem. And it's heartening to read that the minimum for generating hydroelectric power is only a two-foot drop and two gallons per minute. That's a lot less than I would have guessed.
I've often wondered if we could generate power from the creek in back of our house. At least part of the year, it fulfills those minimum requirements.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
