No, I guess I was heading more along the lines of backup power, subsidies and subsequent effects. Whether or not there are actually advantages in the big picture...

See points I-1 & I-2 here and associated links.

That being said, the links you provided are interesting upgrades from a design standpoint.

FeXL, one thing that has shown on a site somewhere is the measurement of infrasonics, low frequency sound waves, with wind mills. This is a known health problem. There are areas where what are known as "Ill Winds" blow, the Mistral being one of them. People have headaches and other affects from them. The cause was found to be infrasonics set up as the winds came through mountain valleys.

However, as CubaMark pointed out, these are design problems. Once the problem is fully recognized, it can be designed around.

I think most of the other things could be classed as NIMBY

Sadly, the wind in parts of NL are too strong for wind turbines, the ocean currents too violent and there is a lack of sun for most of our province.

Almost Genius: Philippe Starck's New Wind Turbine



Quote:
The Revolution Air, manufactured by Pramac, touts itself as a compact home turbine. With two or three blades, it's designed to spin no matter what direction the wind is coming from. (That's a novel, but not unheralded innovation; several companies have produced similar designs.) Prices will start at $3,500--cheap for a turbine
Quote:
Wind might certainly help as a renewable resource--but it's also almost useless in cities and suburbs. There simply isn't enough wind to justify the expense of a wind turbine. It might be un-sexy, but you if live on anything less than a couple acres on a vast plain, you could make a far greener impact by simply weatherproofing your home. (Some have even dubbed doodads like wind turbines as "eco-bling"--the green equivalent of a gold-and-diamond "E.G.O.T." pendant.)

How are you for Geothermal?

My neighbor's just put in geothermal and it is great. Since they will be living in the house another 20 years, it will more than pay for itself. We are considering moving in the next 4-5 years, and so, I just try to keep our oil bill down under $1000 a year by conserving.

Maxwell and the Promise of Ultracapacitors



Quote:
One of the promises of ultracapacitors is their potential to reduce the size -- and therefore the cost -- of hybrid vehicle batteries. The ultracap provides a way to extend the life of and quickly charge a hybrid vehicle's power unit. Ultracaps offer similar advantages for fuel cell vehicles. However, the tandem use of ultracapacitors and batteries does require additional power electronics, which can increase the cost of the vehicle.

Using ultracapacitors for regenerative braking improves fuel efficiency in urban driving conditions, as ultracapacitors capture and store electrical energy (generated by braking) and release it quickly for acceleration.

Compared to lithium-ion batteries, which gradually lose their capability to hold a charge after a few hundred charge/discharge cycles, ultracapacitors can withstand hundreds of thousands of charge/discharge cycles. What's more, ultracaps work well at temperature extremes that hamper battery performance.

The quick energy jump from ultracapacitors is suited for peak power applications such as elevators, forklifts, consumer electronics and back-up power applications.

ZENN needs to get back in the game and soon, before people lose all faith in their company. We shall see.

Actually Dr. G. your faith in Zenn goes way beyond what should normally be expected. They, like our illustrious prez-eye-dent, have reached the point where press releases are useless, only doing something will have any effect at all.
