This has always been my dream.  Capture the energy from a river or a stream for household independence.  I certainly will pay attention to Hydrovolts to see how they progress.  I would even like to see if they could use another engineer on this project.  But I don't think it is so important where it is made.  If you do it right, and have the inspiration to think it globally, it might be designed to be made in any country with a minimum of skill.

The other interest of mine is power from the waves.  Surely there is money to be made from harnessing it properly.  And again, there are a lot of poor countries with coast lines.  What a boon to those economies either of these technologies could be.  Plus the infrastructure that would have to be built and maintained.  It is mind boggling!

I think sustainable design starts with thinking things through.  We learn that, in theory, in design school but it's rarely put into practice.  Our disposable economy has been around for almost a century.  It's no wonder that sustainable design has had a difficult time being accepted in the mainstream until now.

It's good to see more tools to help designer/engineers today get back to the basics of thinking things through and creating sustainable design.

Somehow we need to bridge the thinking and address the disposable society mentality with a sustainable bend to our design tactics. I do think more and more of that is starting to filter into engineers' mind sets.

I doubt if this can be done via improved engineering tools.  The push must come from the customer, the evil marketing dept.  To change these evildoers might require serious legislation. eg Mandated Warranty and Cost Effective (to the customer) Service support for all electronic, white goods and automatic product for at least 10 yrs.

This might reduce the number of 'designed by monkeys' products which are really 'specified to ridiculous timescales by monkeys' products.

@Richardo: I agree that improved design tools aren't enough to ensure a more sustainable mentality when it comes to design, but they can certainly help and ensure the engineer has the data and tools they need to make key decisions along the way. But you're right in pointing out that the real challenge lies within the organizational culture and the vision from top management. Without that, any kind of sustainbility effort is doomed.

Sustainability - Future Trends

I'm seeng where design for sustainability is becoming more and more of a factor in product development and design and I expect this trend to grow.  To penetrate the European market, products currently have to meet EU RoHS requirements.  Also, some domestic states like California are now starting to have their own RoHS regulations.  Whatever side you are on, this will continue to be a growing design consideration in the future.

@Greg: I agree with you, Greg. I think RoHS and some of the other compliance directives are leading the push as are customer requirements for more sustainable products, be in the automotive space or elsewhere. I think there are a variety of different flavors and angles to sustainability in terms of design work, but they will all be a factor.

I think so much of it falls on the head of the consumer.  Consumer's have been conditioned to believe that their station in society is measured by having the latest, trendy gadget.  Certainly, it's not true of every consumer, nor is it true that every consumer device is designed to fall apart after a couple of years.  I have a cell phone that's five years old (I keep it in my pocket so no one can see it), and except for a little chipped fake chrome, the device is still holding up.
 
Sustainability is an important attribute to every design and is typically specified in the product requirement.  Why buy memory that can withstand a million cycles if the product will only be in the field long enough for a thousand cycles?  I have a friend of mine that has a WWII war bird.  He says one of the issues with his aircraft is that nothing on it was designed to last more than a couple of years for sad, but obvious reasons.  The aircraft simply wasn't specified beyond that lifetime.

Warren do you happen to know what the current state is of technology for wave energy-harvesting efforts?

I am no expert or novice.  I just notice things that interest me from an engineering standpoint .  If you look at http://ocsenergy.anl.gov/guide/wave/index.cfm there is an intersting rundown on methods and potentials.  But I haven't seen any off the coasts I go by.  But I wish I could, although, as a former surfer, I might not be so happy hanging 10 with half a gigawatt!
