GOOD: Mini Wind Turbines

www.good.is/ecosystem Our planet is a fragile ecosystem. To keep it in balance, well have to figure out how to harness nature to generate clean, affordable energy. Catapult Design in San Francisco has one answer. Their turbines are cheap and practical, and can power a light or charge a cell phone in villages that are off the grid.
wow i cant believe this ! all those bad comment … terrible ! those ppl are trying to help those in need what is worn whit you ppl ?
Great Job on that wind turbine ! keep up the good work. those who put the complaint are usually those who are making money off the back of those poor ppl.
they might even work for the government to over there. i man from affrica once told me : The best help is the one coming directly there … dentist going over to help … all the rest is kept by the rich
i will invent a working device that will generate free energy…
@91lilfrozone23 Ok you got me there. I was thinking about some more remote places I have been to.
@91lilfrozone23
the government on third world countries steal a lot of money, they could care less about building the infrastructure necessary so all towns get electricity. makes you realize how little you know about the life-style in third world countries and makes you realize how much you take for granted this simple commodities you and i share in our daily chores.
please educate yourself before acting cocky and writing comments filled with ignorance.
peace from guatemala
@MegaMaxemus
no way, for example: i live in guatemala, i own a huge farm (it’s around 10 square kilometers). the farm itself is located around 3 kms away from the main road. there are little towns located inside my property and inside adjacent farms. there was no electricity access until 5 years ago when my dad decided to build the infrastructure so we would have electricity on our farm. this is a brilliant idea, not every one with cellphone service will have electricity.
@91lilfrozone23 yes but there is regular electricity access where there is cell phone service.
@MegaMaxemus
don’t be so ignorant… a lot of people in latin america own cellphones because they are extremely cheap. they just don’t have access to electricity, that’s all.
@CITV08
a cheap cellphone over here is only like 13 bucks, and you can talk around 10 mins for 1 dollar. and to top it all you have an option of just buying the amount of minutes you want to talk, so you can spend as much as 3-6 bucks per month to talk 30-60 minutes.
and pardon my grammar.. it’s 2am so it’s not at its best.
@CITV08
you’re wrong, cellphones over here are EXTREMELY CHEAP. nearly every family owns a very cheap cellphone with the most basic plan. the problem is that when this people live in towns that are deep into the jungle/mountains/etc the asshole governments just won’t give a fuck and they won’t build the infra-structure to deliver electricity to this towns, this is an innovative way in that towns CAN afford to get electricity delivered to their communities.
i’m from Guatemala, i know this stuff
And the guy said to power a cellphone….if they can’t afford electricity they won’t be able to afford a cellphone…..otherwise, great seeing female engineers.
@onthe3dge95 go to windstuffnowDOTcom – it’s Ed Lenz’s design. i wish they had paid him the respect of some credit. Also, check VAWTSdotNET
That’s Ed Lenz’s design – could you please credit him?
No wind. No power.
Charge a cellphone. HA Ha Ha Ha Ha Ha Ha Ha HA Ha Ha Ha Ha Ha Ha Ha HA Ha Ha Ha Ha Ha Ha Ha. I have been to Nepal in the areas that get no electricity. They also get no Cellphone, TV, and radio service to access with these devices. Lights, Water pumps ect.. on the other hand would be useful.
BAD: mini wind turbines
I definitely love the idea ;o) Keep it up!
@blnami
VAWT are connected star connection (3phases) witch gives them more power at low rpm… they are design to start at very low and turbulent wind speed while keeping at low rpm in case of strong wind 350 rpm max… on the other hand HAWT are usually connected in delta connection witch gives them more power at high rpm (800 rpm at max for most of the small ones) In this case these horizontal axis need constant wind speed to be able to start generating. both need a special environment…
GREAT
there are too many stresses on these types of turbines…very high winds could damage them and the bearings have a lot of tension on them…they might look nice but conventional turbines are are better long term bet and can reach a higher rpm
In hot countries (it looked hot and sunny to me) photovoltaic is probably a better bet. Although I live in windy North Cornwall it is surprising how often there is no wind. In particular there is often no wind at night because the cooling land creates a wind pressure that opposes the usual sea-to-land wind. Winter is different! You may have to hang on to your hat and walk at an angle of 45 degrees! Megawatts, Gigawatts going to waste!
@ 29, that is so sad that little village is right under the golden gate bridge, so close to all the wealth of SF. I never noticed them thatch huts down there b-4…
can we get a copy of the design from anywhere?
@Freshbott2 it doesn’t mean they have to be sitting next to the turbine with a fan, they might be inside their home.
tree huggers!
can you please send the design of the wings?
