A river that needs crossing political and tech blogs - On the political side, there is arrogance and ignorance, on the geek side there is naivety and over- complexity

Puting up the wind mill

My test wind mill, works, made from PVC piping a a small electric motor and a quadcopter blade for the rotor. Puts out 2-3v in a small wind.

Testing the aluminium scaffolding pole tower with rope, 3m in hight, with the boat hight thats just less than 5m.

Cutting notches in the fencing post holder to anchor it in place.

Happy volunteer helper.

The windmill is up with some more help, still using a rope as a break till am happy it will stay up for the night.

Using cheap ratchet straps to hold it in place, I dont think these will survive the sun come spring so will have to be replaced with wire.

Testing on Walthamstow Marshes.

Importing goods from China


Am thinking about seting up an import and installation business for small wind turbines from China to put onto boats and power protest camps. At the moment the majority of small scale power generation is from fossil fuels, this is both unpleasant and needless. Solar power in the summer being very viable, this leaves 3-4 month of the year with limited power - thus diversifying into solar/wind set-ups.

To buy small wind turbines in the UK the expense is to high so am trying importing them directly from China - the minimum order when shipping is taken into account is 3 so have sent over $1K to a pretty random paypal account to buy them.

For some background on how to go about importing http://importcrashcourse.com/pay-importing-china/

To get an idea if a company is relabel its good to do as much searching as possible - from the pretty random paypal gmail account they sent me I found out this information https://whoisology.com/archive_6/chinaalps.com that they actually own 4 company’s and are the registry email of the Domain of the company I am buying the goods from. This is a good start.

Then the is the issue of VAT/duty to be paid http://www.dutycalculator.com/

Update: the goods arrived and seem to be of good quality, the issue of installing a tower is the subject of my next post.

Boat Life - Battery power

Need at least 4 big battery’s http://www.alpha-batteries.co.uk/boat-batteries/225-ah-xplorer-leisure-battery/ could have more depending on space under the floor. Then cabling to put them all in series and charging for solar arrays and wind turbine, would need a selection of charge controllers and heavy-duty cabling – then lighter cabling around the boat for LED lighting

The battery’s will need to be put into a battery box with external ventilation.

Looking at wind turbines as little sun in winter

Anyone had any expirence? was looking at this one http://www.leturbines.com/products/le-300-wind-turbine/

With solar and battery’s to buffer (with engine final backup) I should be able to get reasonable reliable power for my boat http://en.wikipedia.org/wiki/Intermittent_energy_source
