Yes you can but keep in mind that it is AC power

Assuming it's a real dynamo then it will be DC, if it's an alternator it will be AC

You're right but the ones i know (I never saw other types on a bicycle) are all AC alternators

Hi Trevors
Fancy meeting a fellow South African here!

I believe every country should explore every possible means of alternative energy, if they can have hydro, wind, solar all together, it's a go.
I like all of the possibilities, but I'm still put off by the price of these. It's sometimes only the real rich who can afford these type of systems in their homes, but for the wrong reasons, they want to prove themselves better that others.

Furthermore these systems take a lot to pay themselves back, especially for the man in the street who can barely afford it.
But it does not end in our homes, I believe the biggest battle lies in the vehicles we drive. I see forums where people in America convert their cars to electric units, hydrogen, etc. That's exciting. We're facing another petrol increase of 81 cents on July 1, 60-something for diesel.

Eishkom also wants to increase their tariffs between 50 and 60%. Wish I could convert my 2002 Ikon to be fully electric, yet self sustained, mmmmm..... what a dream.

If I could afford it, my house's whole roof would be solar panels, even if it yields only 35%. Step in the right direction.
I also do not trust new tech, and think those guys boosting their ultra efficient panels are out to make some bucks of someone else's back. I'll wait for them to put their hand flat on the deck before picking sides. Too many scheisters out there.
Regards

solar panels do work but they are not miracle workers as are no other alternative form, what the layman needs to look at now is how much will power cost in 5 years time with talks of petrol going to 2.3 £/l next year I can't help but think that electric and gas prices could even rise to 10 X what they used to be, if all the power company's can get up one day and say we are increasing prices by 15 % and then wack them up by 45 and our stupid gov sits there and lets them do it who knows what we will be charged in the future.

arrie · 27th June 2008, 08:03 PM

You're absolutely right.
That is why I want to inform myself as much as possible. I can see the day when you have two options, 1 - being ripped off so someone else can become rich, 2 - see to yourself.
That is why I take a serious interest in alternative energy, all forms.
I have two cars, but see it's time to sell the more expensive one, except if I can make it run much cheaper.
In SA petrol will next week be more than R10/l and diesel around R12/l.
We pay about 51cent/unit of power (kWh), what will 60% increase do to that.

We will have to become self sufficient to some extent, like old times, or sink.

Thunderchild · 27th June 2008, 08:11 PM

well try jaycar in australia I've never seemcheaper panels than those but i don't know about customs duty... still 2.6 £/W is a VERY interesting price if you have 500 £ to spend on a single 175 W panel preferably get two at 450 £ each ! if your in south africa you will get near what the manufacturer states in power as you are near the equator at least more than in the uk

I can't access your website at the moment

Oh and I live half a mile closer to them than you do

I've got to admit, every time I drive past them I have to admire them.

Heck - I even come back down the A6 / Finedon way sometimes just so I can get a bit closer to them

arrie · 27th June 2008, 08:35 PM

The going rate for solar panels in SA is around R12 000 for 200W.
So I think you'll be hard stretched get your house running solar for anything less than R180 000, and that's basic needs.
The panels alone will set you back around R80 000.
Shiiiiiiit, that's a whole lot of bucks.
Like I said, only the ubber rich can employ such systems in their homes.
I'll be looking elsewhere.
I still believe in some form of generator from renewable source, but have to prove some theories in my thinking. I also have to build my monster, that costs money, lots of it.
At least I've started tinkering.
What is positive is that I see a lot of people around the world doing exactly that. Tinkering with things that provide energy in some form. That is all we need. Somewhere, some genius is born, and may provide a big enough breakthrough regarding this topic.

Could by my machine/ISP but it won't even attempt to connect to the site.

Just had a mate try it and his works fine so it appears to be a problem with the Eclipse DNS servers I use.

Thunderchild · 27th June 2008, 09:11 PM

works for me in a flash

picbits · 27th June 2008, 09:15 PM

Just added an opendns server in my network properties and its fine now.

There is a company called Bloo Solar that is working on making more efficient thin solar cells, here's a link to their site.
