[MNN] Japanese 'wind lens' will make wind power cheaper than nuclear - Page 3

post #21 of 45
So the third largest country int he world has the third largest windfarmable area and all it takes is 2,640,000 turbines yep seems feasible to me. If the blades are covered with solar panels the energy gain would null the investment cost. But it's still not as good as installing a "third rail" on highways and windturbines on cars................................ Ont he mother nature network science trolls you the you troll science. (not all green iniatives are stupid, just the ones that are.)

With the disaster in Japan I'm sure there going to be on the cutting edge of this technology and will end up setting an example for the world to follow.

They have been trying for the last 10 + years to build and get approved The Cape wind project. But of course all the people that live by the ocean are fighting it tooth and nail. Even tho there all the rich people that are only here for 3-4 month out of the year and can afford the sky rocketing electric bills. Problem with this kinda wind fans is no one wants it in there back yard even if it's gonna save them money in the long run.

The toughest part about Wind Energy is, it's not consistent, I mean the wind doesn't blow 24/7 you know.. biggrin.gif
One day we will find a solution to the energy crysis, maybe before it's far too late...
This looks like a good start though.. biggrin.gif
Entire towns are being run on Wind Power now though, which is great, they buy all the stuff they need and separate themselves from the power grid. biggrin.gif

In addition power is lost over distance through wire, so you can't have a wind farm in Kansas provide power to Maine unless significant breakthroughs occur in transmission. Thus comparing the US to Saudi Arabia is kind of crazy (oil can be barreled and shipped, power cannot).

Still neat concept. Now to make them small enough to make them usable in communities and houses, rather then a few specialized places that compete with wildlife conservation interests.

Batteries have come a long way in the last 10 years. As cars move more towards electric they will go much, much further. In fact I'd be willing to bet that 'shipping power' via batteries becomes a reality before wind farms capable of powering the whole US do.

I still can't see either one in the near future, but interested article and a good idea. I just wonder how much the 'shroud' adds to the cost of an already very expensive wind turbine.

Batteries are terrible storage devices for electricity. Besides, you'd waste more energy charging, packing, and shipping batteries of any significant capacity than you would lose if you tried to channel it across the country via power lines.

Geographically-centralized power generation will be practical (economical?) for the immediate surrounding geographical regions. As soon as you start talking about delivering the power to somewhere a thousand miles away, the benefits are more difficult to see.

So it is like a Dyson wind turbine.

Even if there was only a 0.01 % Chance that everyone in my community could die from a meltdown, I'd still take Wind Power even if it was 2 X More Expensive...

Nevertheless, even the older Wind Power is less expensive than Nuclear, because with Nuclear you have to pay to monitor & upkeep it every day, where as Wind Power you don't have to pay for much else other than Maintenance and minor stuff.

It's good to hear they are still working on new technology, and with as much unused space we have in America, I'd dare say, there is no excuse why we don't have millions of these Wind Generators up by now...

Because they're prohibitively expensive for both the turbines themselves (per the amount of energy they generate) as well as the cost of adding power distribution to get it where it needs to go.

Open Hydro already has a similar design that they are using in a few places http://www.openhydro.com/technology.html, I wonder if it is just a matter of incorporating this design on the existing structure thinking.gif
