Any electricians on here? Question about wiring my house to run on batteries.....

I have just sat and read this entire thread, the iceing on the cake has to be £100 duvey cover. for someone who spends that amount on folding, pcs, servers etc and earns £10k a year?!!

I'm out

Sorry guys :p

I could not live comfortably on 10k let alone thinking about wazzing the lot on expensive bills

Don't forget internal resistance of your batteries also, at higher currents they will produce a fair bit of heat.

Do you have the spec sheet for the batteries you are going to buy?

A123 may be worth looking into as these have a low internal resistance.
 
Are we as citizens allowed our own nuclear reactors as power? Say a nuke sub gets decommissioned by Dave, could I buy that and run my house on the reactor, or would it be completely illegal?

There was a case a while a go about some guy being arrested for trying to make a nuclear reactor in his basement, and documenting it on his blog....

Can you convert 240 volt DC to AC, like a 1:1 inverter? I imagine that would be very efficient.

Well 1:1 isn't very efficient it is the very definition of perfect efficiency, which is why it's impossible. Reading your post again 240Volts DC would just mean lots and lots of batteries, more heat, more resistance even less efficiency.
 
You know you can get financial help with bills etc if there are medical reasons behind high electricity usage? With regards to the washing anyway, not the pc madness :)

There is a slight increase in efficiency from using a higher input voltage to an invertor, but the electronics are mostly on the DC side so the component cost would increase as they would need to run at a higher volage. Something around 48v is commercially available and so cheap to buy.

That video is bogus, I worked out the runtime for a similar setup a while back, no way is he running anything for two days. Even with what looks like two 6v Rolls batteries he is looking at only hours of backup.
 
A mate of mine has been researching making a small wind turbiney thingy in his garden connected to a car alternator and a few car batteries to run his 12v house lighting system.

Not sure how far he got though
 
Probably not very far as you need some serious speed at the alternator end to produce anything useable, when to try to gear them up you make massive drag.
I nearly made my own from scratch ( permenent magnet motor) and carved wooden blades but wind speed in my valley is too low :(
