There is also the volume a DVD drive takes up. And it is powered. With a cable that takes up space and might be needed for a different device (like an SSD).

All of these are factors on desktops as well. Lately, when I open up a machine I disconnect and remove the DVD drive. Better air flow, less power draw and less phantom drive openings (happens on two of my machines).

It simply makes no sense to present most information the same way in browser running on a desktop machine with a panoramic screen the same way it is on a phone screen the user is holding in a portrait orientation.

Especially when the smartphone has a 4K display. Such smartphones could display two or three times as much information as my desktop. So no wonder the new "designed for smartphones" spec. insists on making fonts several times larger to earn the "approved for mobile" rating. Wait, what?

To properly handle something like rainwater takes upfront design. Some kind of roof tank that can gravity-feed all house toilets, and outdoor hoses would be nice.

As to crops, why don't they put down thick black plastic over the entire field. Then capture that water to a swimming pool sized holding tank, and pump it back out via drip/sprinkler systems to water their plants as needed.

As to thinking the consumer should pay for water recycling costs, I'm not suggesting that. But water use reduction and recycling does have to be forced, one way or another -- whether that is a cost per gallon causing prudent use, or even/odd watering days, or "no lawns allowed in AZ". So you offer incentives to those who capture...much like the solar energy people are doing today. The point is we all pay, whether the cost is direct or indirect.

As to road water usage, I found my error -- 68B gallons is the amount used daily, road water amount was for the year. Mea culpa.

The Colorado river is almost totally used by man. Google says the Colorado flow rate is 17,660 cubic feet per second. This works out to about 4 trillion gallons a year...entirely controlled by man. That works out to over 60 times the amount of water that lands on California roads each year. So if road water harvesting is a Dune, the Colorado river system alone is 60 Dunes. We seem to be surviving...

Also, if you recycled roof or road water, the cheapest way to use it -- i.e. zero processing required -- would be to water things. So the same water would end up back in the environment. There is no bank account accumulating funds here.

Average SF home is over 2,000 sq. ft. Assume a roof size, conservatively, of 1,000 sq. ft.

10 inches of rain on 1,000 sq. ft. is around 6,000 gallons available per household per year.

Coastal usage per person is around 145 gallons per day.

You could provide for 12% of residential water needs just by people not sending their roof water to the sewer system.

Imagine if we reused the water that lands on roadways...172,000 miles of highway, average width of ~10 feet...68 billion gallons of water wasted each year...almost what the entire state uses in a year.

You are one of the few mentioning rainwater collection. Well done.

Average rainfall is California is around 10 inches per year. Google says California has 163,696 square miles of area.

1 furlong per fortnight = 0.000166309524 m/s. Carry the naught. [This is to appease Europeans, and hillbillies, alike]

3,800,000,000,000 cubic feet of water fall on California each year. 7.5 US gallons per cubic foot. 28 trillion gallons in total.

Total water usage, average to a per capita is around 2,000 gallons per person.

California population is around 37M.

28 T / (37M * 2K) = 425.

One year's California rainfall could service the entire state's water needs for 425 years.
Recovering one-quarter of one percent of the rain that falls on the state each year would provide enough water for everyone for the entire year.

Here is what you are missing -- helping others.

Most of the activities of my life have been trivially easy for decades. Helping others remains challenging.

If you really are "so smart", you are able to see what a disaster this world is today. Well, get busy changing it. You will be up against the most powerful, greedy, selfish & moneyed people on the face of the Earth. Challenge enough for me. What about you?

Aside from leakage of He/H through the balloon, one tweak would be to start with Helium and replenish with Hydrogen. That way it is inherently less flammable, at least until it has been in the air for a while. Then guys with weaponized drones can use them for cool target practice.

I can't even begin to imagine what usage advantage is to be gained from some of these over the more traditional SATA SSDs outside of very marginal activities, except for benchmark chasers.

Saving & loading very large files -- example: video or audio. Personally I work with 1GB audio files, regularly saving and loading them. I would like an SSD faster than the one I have currently.

With SSDs it is more like: Fast / Cheap / Reliable (pick two).

Samsung delivers the best reliability (for sample size of one anyway) and is acceptably priced. It also appeared to be one of the fastest but this bug has proved it otherwise.

So, if they can fix this performance bug they might just be all three.
