As our dependence on fossil fuels will be reduced, we will need new ways of harnessing renewable energies. Actually, there are lots of ways to get energy - wind, solar, wave and tidal will replace oil in the future. The problem is that we have to find efficient and cheaper options to get power from the sun or from the wind.
Home Energy is a Swedish company which has designed a new wind turbine that is very silent and it’s based on six curved rotor blades attached to a rotor hub at both ends. The new and futuristic wind turbine is called Energy Ball and when it rotates it looks like a sphere and it creates a wind flow which resembles the rapids of a river - this wind flow pattern is called the Venturi effect.
Thanks to the Venturi Effect, the Energy Ball is more efficient aerodynamically as it also catches low-winds to generate electricity. Although the costs seem to be cheaper than for a conventional wind turbine, for the moment we don’t know when Home Energy will start manufacturing and when they will deliver the first Energy Ball wind turbines.
Great idea. The problem is constancy of current. Very few (probably none) devices can run on such variability in power supply. So we then need a battery technology to store the energy converted by the wind generator–but current battery technology doesn’t allow for the type of storage needed to power our daily lives. As a supplement to the constant power supplied by our current electrical generation systems–I hope it helps reduce dependence upon fossil fuels and nuclear steam generation plants. I bet these things are fun too!
Cool!! how can I get one?

Really cool device. I live in the Mid-West where wind turbine “farms” are starting to become more popular because of the amount of wind we get. However, the only problem for us is the infrastructure needed to transport the electricity isn’t available.
A more inexpensive device like this might make it easily available for rural areas, like farmers, and also allow more funds to be allocated to creating a electricity transport infrastructure.
how about fixing a large cone at the venturi entrance??
who’s devising this windmill,,could you please provide me their name and address?
I would like to share some of my thoughts and (experience) with them

there is such a battery, the power grid. Sell the energy back on the power grid when you are not using it and use the power grid when you need it.
jjjj
Awsome!! This looks so cool. I’ll show this to my son that’s 11 he will love this He very into this kind of stuff always thinging of way’s to make this a better place. I would love more infomation on this Thanks Kim kim@hugamonkey.com
Sounds efficient however will it work in a city like Detroit.
I get really excited when I see inexpensive and efficient renewable energy technology. I can’t wait until someone brings that to market.
“Energy Ball är av plug-in typ. Med direkt nätanslutning är det bara att sticka in kontakten i ett vanligt eluttag och all producerad ström kommer till direkt nytta. Enklare kan det inte vara.”
According to the this, the “Ball” is really easy to use, just plug it into your houses network with a normal outlet. So, I gues it delivers some electricity to your house, while you’d get what more you need from the main power grid.
Only problem with this is that you won’t be able to store the energy, but if you’ve only got one of them it won’t give you nearly enough electricity for the “normal house”.
They also stated that the biggest version (210cm diameter) will at most give around 50% of what you need for the normal house, but I gues that number will be way less with little wind.
How efficient is it in a place like Atlanta where the wind doesn’t blow very much? Will I have high storage costs with inefficient batteries? I can certainly partly go back to the energy matrix of two centuries ago, but items like this will appear on an internet that I won’t have the energy to run.What are the repair costs? I lived for 3 years near Banning California which has had wind turbines for over 30 years and about 25% are off line continuously.

I find the Energy Ball a very briliant invetion, I would like to use this oppotunity
to ask for a donation of the equipment. for an orphanage home in Lusaka Zambia.with your donation you will be giving chance to 40 children.
Sir If you made this request possible, you would be Helping and giving chance to 40 orphans for a better life and future.
your responce shall be hihly apreciated.
Yours faithfully,
Edwell Sichone
The thing about it is that you don’t really have to store the electricity. If you have it running through your house, it will power what it can. However, if you’re running less wattage than the ball is producing, the excess electricity goes into the local power grid and is distributed elsewhere. If you have enough excess, the power company will pay you instead. Same thing happens with solar panels.
the ggood thing is it got me an a on my project!!!!!!!
I know this is a horizontal axis, please bear with me, can these be stacked vertically instead?????large masts are expensive and commercial size units would be better multiple….Won’t work on its end??????
Wind lens technology is another promising technology that makes wind turbines up to 6 times more eficient. It may be used for these too.
People should be able to finance these with payments aproximately equal to what they save in energy each month, so their would be no real extra cost and when its paid off their would be real savings. I suggest a Sustainable Energy Credit union able to fund billioins in loans.
nice.. how can a start selling and installing them
nice share
Before you go out and buy one of these, take a look at these testsresults: http://www.lowtechmagazine.com/2009/04/small-windmills-test-results.html
Very interesting (but not earth-shattering) bit of information there Rasmus, many thx for the link.
As a LONG-time aficionado of alternative energies and eco-friendly building techniques, and a now retired Architect, the fact that you cannot yet produce sufficient power to run an entire household off of a smaller diameter wind turbine should be fairly easy to understand the reasons behind that limitation.
But wind power has to inherent advantages to bring to the ‘table’…and those put simply are; When the sun is NOT shining, it is usually because of inclement weather which invariably brings with it increased winds. Also, the OTHER time the sun does not shine is at NIGHT {I don’t mean any intellectual offense}, also when the wind generally blows a little harder. Hence, until more sophisticated technologies emerge in regards to producing power via the physical properties of wind {kinetic}, wind power’s value lies in it’s being combined with solar power by ‘filling in the gaps’.
I have lived this very principle for many years on my horse ranch in the White Mountains of Arizona where I have a dual system of both solar and wind. The solar power generated during the day runs the entire house for the rest of the evening when I get home. And the additional ‘bump’ by the wind portion of my system not only adds to the generated power as a whole, but provides ‘peace of mind’ if I decide to stay up till the wee hours of the morning watching an old movie on TMC ; - )
But then, the above is just MHO…..
Regards.
“Made in Sweden”. More evidence that the USA is falling further behind in technology and science. Thank you so much neo-cons and the religious reich. When the history of the defunct USA is written, you will get full credit for the “dumbing down of America” and the fall of the American Empire.
The sad truth about small/urban wind turbines is that they’re not cost effective or that good at producing energy. The energy output for a wind turbine decreases exponentially as you scale down blade radius and average wind speeds in urban areas and at low heights just aren’t enough to power homes. Spend your money on solar panels instead, or see if your community is willing to pool money for a shared large turbine.
