Comment Summer Fridays (Score 1) 87

This year, the company I work for came up with the idea of Summer Fridays. Basically, we were given the option to finish work at lunchtime on Friday throughout July and August. Great, means you get to start your weekends a bit early, right? Except our client base were still working Friday afternoons, so those of us in client-facing roles didn't get the full benefit; we could have a half-day elsewhere in the week, but it didn't feel as special. Nearly all internal departments buggered off completely on those Friday afternoons, which was annoying if you needed to contact them.

Comment The Ultimate Expensive Bottled Water! (Score 2) 104

There we go. Heavy water, the ultimate in pricey bottled water.

Move over, Perrier. This one's got kick!

It's neat that we can taste the difference, and if bottled water suppliers can mass produce it as a beverage it will surely reduce the operating costs of some types of nuclear reactors.

Knowing the local time for any location around the world is a solved problem. I can add desktop/smartphone widgets that display the time for any location I am in contact with or any new location. I can then tell at a glance what their local time is and roughly what point in their day they are at. Most people around the globe follow the pattern of sleeping when it's night-time and active during the daytime. If everyone globally was using UTC, how do I know what 10:00 UTC means for them? I'm in the UK, so that's mid-morning for me. For a New Yorker, it's early morning. Someone in India? No idea. You also have the issue of the date changing during the working day for many people around the world. Also, the other problems of how you're going to convince 180-ish countries and about 7bn people to suddenly change their perception of time of the day.

No, it's a stupid idea. New York is five hours behind London. If it's 10am in London and I know the local time in NYC is 5am, then there won't be much point trying to contact anyone in the NY office because I can infer they'll be in bed. Under your scheme, I'd have to try and work out where someone in NY would be in their daily schedule for 10:00 UTC.

Comment Gravity-Fed Toilets (Score 4, Informative) 136

it's that there's not enough pressure. There are flushing systems that can produce a lot more pressure even when only using a small amount of water, but I don't think I've ever seen one in a home in the US.

Our toilets are much the same here in Canada - residential use toilets are gravity-fed with typically 6L per flush from a "close-coupled" tank which is mounted directly on top of the bowl. The tank is filled from municipal or well supply, which is typically at 50PSI or so, but the fill valve is the only part of the system under pressure.

They operate by momentum, not by pressure. m1*v1 = m2*v2. The pressure would be limited by the head, which is typically only 2 feet or so. The secret to their effectiveness is allowing 6 kilograms of water to accelerate as quickly as possible in the height allowed by the design and have it collide with the ...dark matter... to drive it away.

Most residential plumbing systems use 1/2" ID supply pipe which would simply not allow a pressurized flush like a commercial toilet to be effective. There are exceptions which use bladder systems to attempt to leverage the standing water pressure of the municipal water supply to drive the flush water down to the bowl as quickly as possible. These systems tend to be expensive, unreliable, and loud, although one day these issues may be resolved.

Improvements to the existing system will require very carefully designed bowls and trapways and exceptionally well-installed plumbing with regard to soil pipe slope and venting. My own home is outfitted with 3L per flush toilets which do an admirable job - I have yet to clog them, even after a visit to a buffet restaurant - despite being purely momentum-based close-coupled toilets without the additional complexity and failure-prone seals in dual-flush mechanisms.

Adding technology is not the answer to this problem. Keeping it as simple as possible but doing the basics really well is key.
