Free electricity?

If you get solar installed (panels and a inverter), and you have an old analog meter- the one with the dial spinning in the center- you can be connected immediately, but if you have a digital meter you must get a 'smart' meter installed b4 they'll turn it on, and that can take a month or two.

There was a story in Sydney in the 1950's about Levenson's Radio lighting their display windows for free by hooking up fluroescent tubes to a tuned antenna. The shop was about 50 metres from the AWA 2CH transmitting tower. They were prosecuted for stealing power, but successfully defended by producing a Broadcast Listeners License in Court. The license permitted the holder to receive broadcast power without restrictions.

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

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.

Put it this way - if there was heaps of free electricity available, would the electricity companies go to the hassle of burning expensive coal or fusing expensive uranium etc to make power?

And *still* noone seems to be prepared to raise the matter of lifetime of these PV systems. There may be a subsidy now, but after the rain gets in and the setup fails, that subsidy may be gone. For the sorts of payback periods I'm seeing reported, these things would have to last many years for the deal to be viable across multiple replacement cycles.

The lifetime figures I see quoted for PV cells are all based on a dry, clean environment. A rooftop is a much harsher deal.

You could do that just the same for a vehicle that was petrol driven. It's a separate issue.

Mind you, weight is only part of the issue. Wind resistance is very important at high speed.

Minus the interest on the money used to buy the panels, whether it's interest paid on money borrowed, or interest forgone on money that could have been put on deposit.

Don't forget that once electric vehicles become popular, a distance tax will be imposed to recover the petrol excise that's not being paid.

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.

Sylvia.

Yes if the technology couldn't produce the wattage required.

That is not self evidently true. Reducing the maximum speed reduces the size of the engine, and drive train, providing a saving in weight, and hence some improvement in economy. But otherwise the link between an engine's size and its efficiency at some particular power is not so obvious. Certainly the Carnot cycle has nothing to say on the matter.

Sylvia.

Of course, those prices do not include installation, regulators and other bits and pieces. However, in a few years, the cost of the panels will be an insignificant cost item. Figure on the cost of amorphous type cells to fall to around 10% of the present price within a few years.

I'm not clear how that's relevant.

I wouldn't want to be so sure about the zero fatality figure, but I'll concede that the fatility rate is probably very low. I have this vague notion that this might be because dodgem cars don't move very quickly, which would make them next to useless as a practical form of transport.

I'm sure such a vehicle would easily go fast enough to allow fatal crashes.
