A evil tainted favour leads to a renewable energy mess


To illustrate what a mess we are currently in. Solar power over the last 10 years has plummeted in cost and crept up in efficacy, leading to a shift to sustainable energy in many western country’s. This decrease in cost had nothing to do do with western entrepreneur and the capitalist path. The funding (huge subsidy) was paid by the Chinese government (and the people it taxes). It was a state planed and funded attempt by the chines communist party to gain dominance in this new era, they did this by top down building of huge solar power factory and infrastructure, the plan was to bankrupt the western producers by swamping them with cheap products and then profit from cornering this global future industry.

This seceded up to a point but they over steeped the production so were caught in a spiralling decrease in price that easily swept away the nebulous western solar industry. But also run away and undermined their own economic base, central planing in a “capitalistic” hybrid system is hard to control. So, we have a moment of hugely under priced solar flooding the world market. This has been proven to be very challenging to our existing energy monopoly’s. With no indigenous solar industry left the is nobody to lobby our legislators any more to keep the market open. Our monopolist are putting legislative blocks on solar roll-out in place to prop up their old industry’s and apart from some green’s the is little standing in their way.

China inadvertently doing evil dose the would a huge favour, but the “evil” in the end taints the “favour”. Its clearly a mess and if we still had a grown up politics maybe we could do something to mediate this mess.


Wind Turbine full of water

Charge controller looks fine

Smartphone Solar Charging

Am thinking of running a workshop on small scale solar power.

Here is an example of a cheap set-up that will run your large smart phone (and charge a tablet)

This a Samsung Note phone to give you an idea of the size.

The panel is rate at 1amp were the 6000mAh pass through USB battery is rated at 2.1amp's

Thus the set-up will charge your phone as fast as if it was plugged into the wall, using the battery as a reserve of power to achieve this.

This is a light weight and cheap solution costing less than £40 a realy usefull travel and adventure tool.

Mobile Solar power for a laptop

Am thinking about running a workshop on portable solar power.

This is 32w folding solar panel with a battery pass through DC to DC transformer and 13' video editing laptop running adobe CS.

All Folds up and fits in a laptop bag.

The solar costs £200-250 and you need a relatively expensive ultra book with 3D graphics card to do CS editing. Portable solar will struggle to power a full sized editing laptop. Total cost just over £1000

Chargeing your Laptop form solar power

12V Macbook Magsafe2 Laptop Charger, rather than running an inverter and then your standard charger this will allow you to charge directly from your 12V batteries being more effecient and saving you power. Link

12V Universal Laptop Charger, rather than running an inverter and then your standard charger this will allow you to charge directly from your 12V batteries being more effecient and saving you power.

Adjustable output voltage at 15V, 16V, 18V, 19V, 20V, 22V 24V
Support most of the Notebook for HP IBM COMPAQ and SONY (With circle plug) LINK



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.

DIY solar power to far

Many of the times I tell people how easy it is to build a small solar power set-up, I am given a dismissive and superior reply that I should be making my own panels not advising people to buy ones. This like many insecure replies is both wrong, dis-empowering and could be dangerous. Here is an article on the subject http://solarelectricityhandbook.com/Solar-Articles/build-your-own-solar-panels.html the article highlights its not a bad thing to actually make your own solar panel, just don’t do it as a serious way of generating DIY power.

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.

Light portable solar laptop power

This might be a good portable low powered laptop charging system.

Mercury27 Portable & Foldable 27 Watts Solar Battery Charger. I haven’t tested this and it gets mixed reviews but for bang for the buck this is a very good deal if it works. Get it here

MP3450E-60 27,000 mAh Dual External Battery Pack. For a more portable set-up you could use a single battery.

If anyone is doing a trip to the USA I would be up up for ordering one if they could brining it back to test.
