And not based on their own personal choice?

No, because most people are grossly uninformed, and unable to grasp statistical risks. If their actions only affected themselves it would be fine, but an unvaccinated population endangers others.

Seriously, why do we have such an issue following the advice of peer reviewed experts these days?

Comment Re:saturation (Score 2) 30

In Australia it's because of two main issues:

1) Electricity providers charge both flat rate access fees, and per kWH usage, but the access fees don't truly cover the cost of the network. When usage goes down they are left short.

2) Many electricity providers took advantage of a government scheme to build excess capacity in to the network, and charge users for it. In some cases whole substations were built and sat around unused. Now that people are using less or going off grid, they are left with expensive underutilised capital.

The funny thing is, the more they try to claw back and/or raise fees, the easier it is to economically justify going off grid. They are shooting themselves in the foot.

What's rarely mentioned in the media summaries is that when the EmDrive moves, the field in the microwave cavity gets consumed and you have to spend energy to replenish it. This makes it ideal for station keeping (or hover cars) where you just need to provide a balancing force.

Anyway, there is no free lunch here and energy is still being conserved. It's only momentum that is in question.

The main textural components in chocolate come from the cocoa mass and cocoa butter.

Creaminess comes from particle size, and the cocoa mass (and sugar) spends hours and hours in conching mills to get it around 20-30 micron. The mixed chocolate then spends a long time in tempering circuits to promote the right crystal size in cocoa butter fatty acids.

Super/Ultra capacitors are not so simple, and share things in common with batteries.

Their total capacitance comes though a combination of
1) Double layer Capacitance - separation of charge in a Helmholtz double layer between the plate surface and the liquid electrolyte, and
2) Pseudocapacitance - electrochemical storage by redox reactions at the electrode surface. This is very battery like.

solar cells are only useful on south-facing slopes

That's old school thinking when panels were ultra expensive.

East and west facing panels can still generate 70 to 80% of the power of south facing panels, but they shift their peak production into the morning/afternoon - which happens to match residential demands well. By having all three - east, south and west, you get a longer generation profile and reduced battery requirements which is a great financial benefit.

Even north facing panels arent terrible and can generate 40 to 60% of a south facing panel in full sun, and this margin reduces on cloudy days where they receive scattered light.. The economics are marginal though and it's probably only viable with the cheapest of panels.

non-matching tiles on the north-facing slope of the roof

SolarCity & Tesla have already though of this and offer pattern matched non-solar tiles.

Maybe you don't like it but I sure as hell do.

I leave my phone near the bed and use it as an alarm. It sits on a phone stand so that I can read it, so replacing that with a wireless Qi charging base takes up no more space. It's super freaking convenient and works great.

Better yet, I'm not wearing out the USB plug with hundreds of matings.

The car is not compliant, that's why they are offering returns & payouts. It makes no difference if people care about compliance or not, it is legally required to be compliant in order to be on the road, period.

Then, if people choose to get a fix they will be left with a car that is less powerful, because that's how the cheat mode worked. People will end up with a worse car than they bought, and that's why they are offering compensation payments.

But don't let the facts get in the way of a whinge!

Comment More to home automation that ordering milk. (Score 1) 91

Not really convinced this is a "serious" platform for home automation - turning on Hue lights or playing music via voice command is hipster cool, but where is the deep support for real physical infrastructure:

- X10 and Zwave lighting
- Thermostats of all varieties, including the dumb kind
- Infrared, with support for both regular home theatre gear AND wall mounted air conditioners.
- Curtain / blind controllers and aircon zone controllers
- Relay contact outputs
- Energy monitoring and trending

Then, what about all of the rules that make Home Automation automated?
