Fuel Cell Safety

I remember being taught many years ago that "risk" can be measured as a product of: Probability - ie the likelihood of an adverse event happening Impact - ie the effect that the adverse event would have on people/systems Later on, I did a course on the medical effects of nuclear warfare which includ...

Green Car Innovation Fund

That gets to the problem that gets brought up about renewables that they aren't base load, ie when everyone turns on thier air conditioner the power company can't ask the sun to shine over thier solar panels Maybe it's different in other states, but an interesting thing I've noticed here in Perth i...

Smart car conversion

I've occasionally wondered about the Smart as an EV but it'd be an expensive donor. I notice they're jumping on the green wagon - now have a micro-hybrid drive . Methinks the "micro" refers to the amount of "hybridity". AFAICT, all it does is turn off the motor when you slow down below 9kph and turn...

new newbie section??

I like the wiki idea :-) Is there some nice free open software for doing circuit diagrams etc so people can document their working vehicles/ideas? (Picture tells a thousand words and all that) Have you tried Dia? It's an open source program (ie free, as in beer) that is "is roughly inspired by the ...

The dear and best-vs-good and cheap Batteries

There's been a lot of excellent information about batteries on this forum, but this superb summary takes first prize IMHO. It belongs on a FAQ "Which battery technology should I choose for my EV?"

Hi Ian, From the slide show, it seems to me like it was a great talk. To the point, punchy and pushing all the right buttons. How did you feel it went down?

Something like this maybe? I suspect they'd not post it to Oz though Image and it probably wouldn't have the range to cross to the Panama Canal, let alone the Pacific after that!

Hi All, I've been doing quite a bit of research on this. I actually killed the ICE in my yacht about 6 years ago, but at the time knew nothing about marine electric motors so replaced it with another ICE http://forums.aeva.asn.au/smileys/smiley19.gif .

I spent 13 years in the Navy and I enjoyed most of it, but have a few tips. Firstly, any promise made to you that's important to you, get in writing. I know of many people who were made promises by recruiters that simply never eventuated. Secondly, anticipate being away from home a lot. If you have ...

Hi lithbattboss,

It wasn't me actually, it was "The Doctor" (see page 2 of this thread) who was interested, though I may well be contacting you in the near future anyway.

Heater-- Demister

Hmmm, I wonder if it has a pump included, or if it relies on convection flow? If the latter, would convection flow be enough for effective use as a car heater or would one have to add a water pump as well? I suspect a water pump would be needed for maximum efficiency.

Cheers,

Hi Steve, 2kW, wow! If it were me, I'd be trying to find out the actual output from an auto A/C compressor and seeing if there was a 12V one that produced the same output. Alternatively, heat pump technology is touted as being very efficient, maybe there's an option there? Interestingly, this Wikipe...

Air Con and Power Steering

Hi guys, I know little about refrigeration, but on my yacht I have an extremely efficient fridge. It uses a 12V Danfoss compressor and a tiny condenser. When running, it pulls a maximum of 4A. As my fridge has very thick foam insulation, I easily run this fridge day-in-day-out off a couple of 18W so...

I cycle to the local shops (about a km away) so I'd not use electric assist for that, but currently, I use the ICE to commute to the station each morning and I'd probably be interested in it for that. That trip only has one "hill" - an overpass actually, not too steep. Sorry to hear you have health ...

Mind you, it's a bit hard to find anything about them on the Avanti site ATM so maybe they're not doing them anymor...
