 Post subject: How to Lighten alternator load
PostPosted: Thu Jun 07, 2018 2:30 pm 
Hello to all
I would like to know how can I lighten a car alternator load.
I am trying to charge 3 car battery of 12 volt 45 amps with an alternator of 12 volt 45 amp in my garage.
The alternator run with a small petrol motor but it became "heavy" if I connect more battery to it.
I know there is a cheap way to make it lighter but I don't remember where ...

 Post subject: How to reduce energy loss!
PostPosted: Mon Mar 05, 2018 12:15 am 
This time of year all energy used in a house in the end adds to the heating, it does not matter if 100W is used in the TV the lights, or a simple heater, unless it is allowed to escape, then it heats the house.

So saving energy equals stopping it escaping, so there are a number of ways for heat to leave the house.
1 hot water down the drain not much we can ...

 Post subject: Gas Consumption - Vaillant ecotec combi boiler 831
PostPosted: Sun Jan 21, 2018 4:56 pm 
I do believe my combi boiler is economical but I am curious as to how much gas it consumes and the best way to use the boiler.

What I am after finding out is - how much gas does the boiler initially use when I switch the heating on when it has to heat up the water in the expansion tank (correct me if I am wrong). At that start point, does the boiler use ...

 Post subject: How to work out energy used?
PostPosted: Wed Dec 27, 2017 12:57 pm 
It seems easy until you place items in your house. So tumble drier, put an energy meter on the plug and you can measure the electric used. I can also use the washer/drier and also measure electric used. however with the tumble drier I am pumping air heated by the central heating out side as well.

This is just an example, there are many more where some part can't be easy measured. Be it a ...

 Post subject: SAVING LOTS WITH PC POWER SUPPLIES
PostPosted: Thu Nov 16, 2017 11:28 pm 
I have been working on diy projects for a while. Thought about saving energy etc. and i got an idea. Most of our a/v appliances have tranformers to give dc power to the circuit boards . so i thought about saving energy by hacking my tv to test my idea. I found the main power supply and tested the dc output and found it to be 12vdc. So i took apart a pc power supply. ...

 Post subject: Cavity wall insulation when building blocks are insulated?
PostPosted: Thu Jul 13, 2017 9:03 am 
Hello :-)

Just a quick one...

I live in a private 3-storey apartment block and the managing agents are in the process of arranging cavity wall insulation. Presumably, the cost of this will eventually be passed onto the residents.

According to the NHBC Home Owners Information Card still in my possession, the type of wall insulation used was 'Thermal bond block' when Tay Homes built the place ...

 Post subject: Sunamp Blogger Asking Some Questions
PostPosted: Tue Jun 20, 2017 9:39 am 
Hey there,

I am new to this forum and was hoping to ask a few questions.

I am student on an internship at the company Sunamp, a company who produces heat batteries which are similar in concept to the Tesla electrical storage device but instead stores heat instead of electricity.

They are a growing small and medium sized enterprise (SME) and are growing in size. They have taken me on board to promote the company ...

 Post subject: REAL Green Energy?
PostPosted: Sun Jun 11, 2017 7:19 pm 
Green/Renewable energy is becoming more widespread and I don't want to debate whether that is good or bad and the reasons behind it. What I'd like to hear thoughts on is what I call REAL green energy, which to me is alternative energy sources that are actually useful but also cost effective.
For instance, you can cover your house in solar panels if you want, but the actual payback period on that is so long ...

 Post subject: Wind turbine
PostPosted: Sun Jun 11, 2017 10:56 am 
Just wondering, have any of you (or folk you know) got a "wind turbine"
If you have, which one any good etc?

I was thinking of getting one just to see what they are like, I also know that despite what you may think they do need a fair bit of wind to make electricity, and this wind needs to be constant if its to be of any use, so all I was going to ...
