Solar scheme gone wrong

Thought I'd post to correct some of the well-intentioned, but erroneous information about domestic solar systems. I've had a 5KW system on my home in Waikiki, Western Australia since May 2010. I have tracked the power generated since the beginning via PVOutput , so you can see all the detail there. ...

iMEV price drops to $20000

After registering online my interest in the iMiEV near enough to 2 years ago, I've just had an email and a couple of phone calls from Mitsubishi about the car. Apparently the Osborne Park MMC dealer here in WA will be handling local enquiries and is due to get a demonstrator early next month. In res...

Ebike Power limits, proposed legislation

Hmmm, hadn't seen Steve's post above when I posted mine. I guess that's one person my arguments won't reach. I should say that I have a medical background and I've seen the smashed up bodies in ED and the months and months of rehabilitation afterwards. While the victim suffers physically and emotion...

Ebike Power limits, proposed legislation

When doing the numbers on things like this, you also have to look at Safety, because that is one thing the "Powers that Be" will be scrutinising closely. Vehicle-related injuries cost our society dearly and those of us who pay tax, pay this cost. So, if electric bicycle power is increased, that woul...

Emergency 100A DC fuse

BTW, my mate will be in Kupang by 30 May and I expect he'll do his darndest to source 2 or 3 replacement 100A Circuit Breakers there. I was in Kupang last month and it's amazing the range of gear you can buy there, just so long as you can find someone who understands what you're looking for, or else...

Emergency 100A DC fuse

Hi guys, Thanks for the information. The guy is an ex-RAN submariner who serviced and maintained the diesel-electric systems so he's got a reasonable tech background and understands the issues pretty well I think. I suspect that, like me, he understands the fundamentals, but doesn't have the detail ...

Hi Johnny, thanks for the reply. I've swapped a few SMS with him and have a bit more detail. He actually had a 100A circuit breaker in place, but it blew up because of "operator error" - the anchor control has separate buttons for up and down and someone pressed both together http://forums.aeva.asn....

Outboard Motor conversion

I agree that unless you're keen to spend more money building something that probably won't work as well as an off-the-shelf unit, I'd not go down that path. WRT cooling, most OTS units are direct drive, with the motor under water which makes cooling a non-issue. Lithbattboss, are you referring to a ...

I believe it blows down onto the fins but wouldn't really mattter as it would have quite a decent amount of passing air blowing on the controller fins.

electric 40ft yacht - discussion and advice

Do you carry the 400L of diesel in case you need it for one long stretch due to sail failure? Actually, rig failure is more likely than sail failure - most cruising yachts have more than one set of sails on board. However, if your stick comes down you're a bit stuffed! And Murphy ensures it will ha...

electric 40ft yacht - discussion and advice

How much diesel would you need to carry in a 40ft'r. I would think that your 7-8 Hours on prop drive is at 1/2 power, is that fair enough? So if it consumes 10 litres of diesel in 1 hour you have a measurement of how much energy it takes to power the yacht by prop at cruising speed. Sorry, you'll n...

Ha! The sort of wind generator I was thinking of would do 22 kW in 10 knots of breeze, hence the 40K price tag. With a mast about 18m high you could carry a turbine blade dia of about 14m. Push the thing along at hull speed in any sort of breeze! Then you wouldn't need a genset or solar panels. Sou...
