Re: Wind and Solar vs Coal, Gasoline, Nuclear

So it sounds like they are pretty knowledgeable in their field then :? . As part of my day job, I collated all of the references cited within this report and examined them pretty thoroughly. It checks out - they aren't making this stuff up. They cite all the best automotive, mineral processing and e...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

sigh.JPG This is the 20% to 30% more emissions I was referring to. As in, an EV's manufacture results in 20 to 30% more CO2e than an ICE car. Both ICE and EVs emit greenhouse gases at manufacture - indeed EVs result in more. Yes, the graph looks at life cycle emissions, but tell me, once it rolls o...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

We've already hit peak car. In fact the number of private vehicles in the global fleet is dropping, and will continue to. So when we start replacing ICE vehicles with half as many EVs, year on year, we will end up in a better position than business as usual. EVs have an emissions hit at manufacture ...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

So a CO2 goes from 300 ppm to 400 ppm. That is, every cubic metre of atmosphere now has 1.5 times as many CO2 molecules as it used to have. And you're telling me that is the same as a 0.015% increase... You have a very unique way of trolling - by demonstrating a lack of understanding of mathematics ...

Glass recycling is another example where once it's traded on the open market as a commodity, its value plummets and nobody cares about it. At least you can add it to cement / road base / artificial reefs and it doesn't have any further ill effect on the environment. Or you can re-cycle it, but it's ...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Bollocks. Solar panels are being replaced after 8 or 9 years because installers don't want to (or the CEC says they can't) add to existing systems - rather they are advised to replace all of the old panels with higher powered new panels. At $155 per panel, it's cheap enough to do this. The 8 or 9 ye...

Re: More info about the new lightening motor cycle

Will be interesting to see how it goes considering it will be completely manufactured in China.

I notice it's taken a big power hit compared to the LS218 - Only way to get respectable range is to replace motor volume with battery volume I guess.

I believe that you need in general about 1000% wind/solar installed to have a clear shot and running truly on renewables 1000%. Really? As in, building 10 times the nameplate rating of the equipment? Or 10 times the nominal generation rating? 10 times the nameplate is very generous - I would have s...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

My prediction for 2050: Australia will have a HVDC power line crossing the Nullarbor so that West Australian solar energy can be exported to the east coast during periods of high demand. Similarly, East coast solar power can prime WA with energy first thing in the morning. We may even be exporting r...

Re: jonescg's NEW electric racebike BUILD thread!

Well the 800 V to 48 V unit costs $800 or so. And then the 48 to 12 is only about $80. The first stage is capable of 1.3 kW, but the second stage is only good for 320 W... I guess you can parallel several of them if you needed more power, but 30 amps at 12 V is heaps for a bike.

Indeed the cheapest watt is the one you don't need. The way homes are built in Australia is an embarrassment.

Re: jonescg's NEW electric racebike BUILD thread!

Sevcon do a 1.5 kW DC/DC converter which takes up to 800 V DC and steps it down to 12 V. But that's about 4-5 times more powerful than it needs to be.

Re: Assembled Hi-Power LiPo battery packs - any interest?

I figure it's about time I shared the Prelude battery pack. This battery pack sits in the fuel tank space and has six 12s10p liquid-cooled modules in series. The conversion needs two more modules up the front to make a standard 355 V nominal pack with 24 kWh of useful energy. This rear battery store...
