What then?

PHEVs perhaps but the 40% efficient auto diesel is on the way. Plus it
can provide spare heat for cabin heating 'for free' in the important
European, Japanese and N American markets.

Sea going diesels with co-gen are right up in the 70% efficiency
category now which is at least twice as good as the efficiency of
GENERATING electricity for the grid, never mind the losses in battery
storage etc.

So you do not follow the CSIRO vision where your roof is covered in
plastic upon which is printed a solar panel charging up your electric car
batteries?

And of course your car could be covered with them as well. What's also
missing atm however are suitable batteries.

Yep, great choice, lead acid or expensive flights of fancy for impulse
power.

Lead acid batteries weight a collosal amount for the energy they store. And
you have to drag that weight around. They also don't last very long.

blink, how is your foot?
No battery lasts long if you abuse it, but LA batteries properly used can
be ancient.

The real problem is that they are so ubiquitous and installed in
inappropriate application.

OTOH, modern batteries are basically flash in the pans.

So why is almost no-one using lead-acid ?

Graham

for mobile vehicle?  weight?
For ups's and independent power system? Obvious choice.

the place for lead acid batteries is stationary locations where power
drains are continuous and only vary slightly. up until now, there hasn't
been many generally viable, economical alternatives. there is a lot of
work in the instant power area, probably because if has the least
competition from lead acid.

Silicon isn't flexible. So you can can have a crahworthy deficient 'box'
vehicle you can mount PV panels on or get real.

I suggest you look at insolation maps and the futile amount of energy you'd
harvest too. It's BONKERS, expensive and plain ridiculous.

A totally loony idea. The sun shines when the car isn't there. Besides, few
roofs are properly inclined for good generation and the efficiency of solar
panels is a sad joke.

~ 15% for expensive silicon crystal types and ~ 7% for thin film whose
durability is unknown. Don't believe newspaper articles, read the science.

I suspect there would be a reasonable market size where the car is there;
retired, house parent, home office, houses now professional offices, etc.

The argument was futuristic, a cheap coating applied over a mass area was
cheaper than the high efficent PV over a small area.

Of course, no one is willing to discuss futuristic improvements in PV.

How much energy per day can be captured from the surface of a car?
Incident sunlight at midday is in round figures about 1kW per square
metre, but of course solar cells are not 100% efficient. Indeed, they're
nowhere near.

http://en.wikipedia.org/wiki/Tesla_Motors

"Tesla Motors' first production vehicle, the Tesla Roadster, is an
all-electric sports car. According to test results from an EPA
certified laboratory, the car has a range of 221 miles (356 km). The
company and reviewers state that the Tesla Roadster accelerates from
zero to 60 mph (100 km/h) in less than four seconds, and has a top
speed of 125 mph (201 km/h) (limited for safety). The cost of powering
the vehicle is estimated at US$0.02 per mile."

And if you have a spare $130K you can have one.
Most of the cost is the batteries.


Re: Electric Vehicle Seminar - Sydney

That's the killer, plus the cost of replacing them.

Graham

Plus the wider cost of millions of tons of electrochemical waste, once the
batteries start to wear out across the globe.
