Won't that weaken our magnetic field and maybe screw us up completely?



Re: Free electricity?

probably just extract energy from the earths spin (by deforming its
magnetic field and causing drag vs the solar wind).  There's an awful
lot of energy there, it's been powering the tides and lifting the moon
for billions of years

if the earth stops spinning we're probably screwed

Generators don't use up their magnetic field.

But the Earth's magnetic field appears to flip from time to time, over a
period that's uncertain. If Earth's population started depending on the
field for generating power, it could find itself up a creek without a
paddle.

I heard about someone in the mid-80's who'd erected a large complex antenna
to harness radio signals, and then modulated them down to 240V 50Hz to power
his house.  Apprently he was caught because no-one beyond his house could
pick up 2WS.

I don't know if the story is true but it's technically feasible.  It's just
like a transformer except the secondary winding is some distance from the
primary winding.  That's pretty much how a radio works anyway...

It seems highly implausible. He'd have to be capturing a significant
proportion of the total transmitter output. It's certainly an urban myth
created by someone with some knowledge, but not enough.

Agree. If this worked, it would be a well known method for radio

You might have a shot with stringing a wire under high voltage power
lines and tapping off it.

Holding a 40w tube in the air under 330kv lines with the other end
grounded will light it dimly,
so you might be able to light a fluro tube if you go high/long enough
and ground the other end.

Likely very illegal and very noticeable unless you use very thin wire,
and probably dangerous.



Re: Free electricity?
Quoted text here. Click to load it
What you are actually picking up there is the electric
charge across the air. There is a large potential difference
between the ground, and the end of the tube 3m off the
ground. Because the air has a very high resistance, the
current flow is very small, but sufficient to light the lamp.

I've heard of cases where farmers have run coils of wire
under power lines across their property and got usable
amounts of power.

They've been found out though, because the power co's can
detect if there is a drain on the system.

As for the video in the OP, I believe that he genuinely is
charging his phone - ie the video isn't faked. But it
doesn't work for the reason he thinks it does, and the power
isn't free. He is using his house wiring as the primary of a
transformer and the antenna as the secondary. Consequently
his load (although miniscule) would be registered by the
power meter on his house.  I can guarantee his mobile phone
charger would stop working if he walked outside, or turned
most of his other appliances off.

Because seppo-land house wiring is lower voltage, and hence
higher current than here in Aus, the EM field is stronger.
Consequently it will develop more power than it would in the
same scenario in Aus.

Plenty of people listen to crystal radios, we built ones with a single component

Jaycar or Leisuretronics had a solar powered hydrogen generator kit.  I wondered
if it would scale up for practical fueling purposes, apparently it does.

"which would lower CO2 emissions by using less expensive off-peak
electrical power."

It only lowers CO2 emissions if that off-peak power comes from nuclear
power plants. Otherwise it will usually come from coal.

"During daytime peak power times, the Solar Hydrogen Station can export
renewable electricity to the grid, providing a cost benefit to the
customer, while remaining energy neutral."

Now, while possibly true, that's just plain dishonest. Energy neutrality
is one thing. Carbon neutrality is another. If you're using colar fire
generation at night, and then displacing gas fired generation
(typically) using solar power during the day, then you may be energy
neutral, but there will still be a significant net CO2 production,
because coal fired generation produces more CO2 per unit energy output
than does gas fired generation.

0.5kg of hydrogen is 500 grammes, so 500 * 6 * 10^23 atoms.

Splitting water requires one electron for each hydrogen atom, so that's

500 * 6 * 10^23 * 1.6 * 10^-19 columbs.

It requires a potential of 1.23 volts, so the total energy requirement is

500 * 6 * 10^23 * 1.6 * 10^-19 * 1.23 Joules.

which comes out 590.4 MJ, or 16.4kWh.

So if the electrolysis is 100% efficient, and you have 8 hours of
daylight per day, you'll need 2kW from your solar panels.

Show me a 2kW system that costs only a few thousand dollars.

They're subsidised. Those figures are merely what the consumer has to

Jaycar has 175Watt for $900.  So about $10K from your local hobby shop.

But solar panels haven't entered large mass production yet, who uses them?

Plus you could halve the weight of the car with a smaller engine and carbon
fibre, etc. etc.

For 350km a week you'd save $50 per week in fuel, that's $2500 per year.

Plus the ton of CO2 you'd not pollute each year.

It's clearly in the practical range.  Bottled energy from the sun by sticking 2
electrodes in rain water!  PERFECT!

Unless electroloysis is only 10% efficient, I doubt 90% goes into heat.

Between 50% and 94% depending on who you believe. Getting the maximum
efficiency probably requires that it be done slowly. If you increase the
voltage above the minimum required to produce electrolysis, then the
extra voltage times the current is energy that is being wasted.
