Not hot enough. Basically the same as my black pool.

But thanks for another site to for research.

Did you see the size of the tomato's?

Huge like a child's head.

yah I agree. Seems a bit high.

The are using desal water from evaporation. Very low in Salts. If not zero. They are also in a green house not open field. If the soil gets contaminated with salt they can simply dump it into the sea. Which would not be a bad way of sinking some carbon come to think of it.

In Australia water the desert just results in evaporation of the water. Which leaves behind salt on the land. It was not well thought out.

Clearly different methods of bring green to the sand.

It was sponsored by a fertiliser company.

I have considered the trough. But there is so much lost solar radiation this way if you don't have some tracking in place.

Basically I get more solar heat transfer if I just have a glass cover over a shallow pond that is painted black. I just don't get the temperature high enough to create a more efficient evaporation. It's just ends up being slower at a lower temp. Which then results in more biomass growth. I'd like to have close to boiling to hinder algae and such in the solar collector system.

So I'm stuck with a lot of labour with either method. However the construction costs are much lower with the black pond method.

I have been tossing around some ideas on how to automatically adjust the angle using struts that expand and contract with heat. Just need to find the right balance of expansion and contraction I hope to cause the system to angle itself as the sun passes overhead. My current thinking is something like a shock absorber filled with gas. A gas shock could cause contraction or expansion of a joint when cooled. So somehow tying the heated sea water into the system to control it's own angle.

It's really good to see some one follow through on this. This is excellent.

I've been toying and drawing up plans for very low maintenance solar desal for years. All the same basic components as this. But they have taken a few steps further than I was thinking. I had not worked in humid air as a means of watering plants. It really solves a lot of issues with condensing the water.

Problems like biomass build ups and the effort to clean it. Now that effort is productive as it is harvesting food not just cleaning sludge off the walls.

I really like it.

I had wind to pump salt and fresh water up hill. So that I would have a reserve of each at all times. That way wind could be used to build kinetic energy and store it as raise water mass. Salt water of course to feed the evaporators and to flush waste back out to sea. Fresh for obvious uses.

Something I have struggled with is a solar tracker that would allow a mirror to stayed focused on a water pipe to heat it to near steam to accelerate the evaporation. Something that does not actually require elctro-mechanical input.

It has to be commercially viable. So choose stuff people want.

This is about growing food people will consume. If in the same shoes I would choose the same crops. Not because they are the most efficient, not because they are the best for you. But because it's the income that will allow the plant to continue to grow food. Local food.

And it's that last two words that matter most. Local food. As in the amount of oil used to transport the food from a far off land is drastically reduced.

Even if the crops are not the best source of nutrition they are still better for you in the long run. Simply because the cost in carbon and energy is so low.

And to top it off this is only the start. In the future when the tech becomes cheaper and easier to implement the market is easier for people like your self to grow a radish or 6.

I should have included this article which puts things in better perspective.

US broadband is more expensive than a few countries.

Also the available speeds vary widely as well. The US has a decent speed overall. Given that a significant amount of content is available in the US. The real world speed in the US is significantly better than other locations around the world. See: http://www.netindex.com/

Lets also factor in region locking of content. The US generally does not suffer from the issue. Other regions around the world are simple blocked from content due to the region they are in. Again the US is at a significant advantage here.

There are a lot of other countries that are a hell of a lot more expensive than the US. Case in point a first world country Australia.

Overall the Internet experience in my humble opinion in the US is vastly superior to most other locations around the planet.

Now lets also factor in penetration of broadband and average household income. The US fairs very well indeed when you start to think about these factors. However the US is still behind some notables. Korea for some time still be the bench mark that other countries try to achieve on all fronts. Other countries are embarking on plans to significantly improve speed, bandwidth, and costs.

This article should have been about. If the US doesn't do anything to upgrade it's aging internet infrastructure it will soon be one the the most expensive and poorest performing broadband countries in the world.

Finally a reader that realized that the electrocution from the charger has nothing do with the cables. The charger and the cable are separate things.

People the cable is a separate thing from the charger. If you used one of the dodgy chargers with a genuine apple cable you are still as likely to be electrocuted.

Other readers please stop spreading the FUD that it's about safety. It's not.

And guess what Lightning is not an international standard. It is a variation on a standard. And Apple can do anything they want with it. It's called a proprietary connector. There is nothing at all illegal about what Apple is doing. It's entirely self defeating.

Is it greedy? Yes
Does it have anything to do with safety? No
Is Apple doing the right thing for it's customers? No

Actually the Android game is very very tight on margin.

Samsung makes money only because the basically build the entire supply chain from essentially raw materials. HTC is loosing money badly. LG I don't know. Motorola well they are now google so those books will be cooked.

I love Android it's just a game that Nokia would never have been able to profit. I thought they should have gone with Android myself back a few years ago. But clearly that was a bad idea in hind sight.

Nokia was caught with their pants down. The worst thing was they didn't even know it for 3 more years. By then they lost the market they owned. They simply could not grasp touch screens. The N95 was a phone that should have opened the eyes at Nokia. Here was a popular device that did pretty much every thing. It had a huge screen for the day. Did it really have a successor. Did they try to innovate after it? Nope. They just rehashed the same format a few more times.

The next device needed to be touch. And it needed to be good. They didn't even try. They put out what was it 4 rev's of the same format? Then they basically collapsed, living off the life support of a HUGE cash balance. Which is now long gone.

In the end the only option was sell to MS.

Qantas has had a form of spyware for years. Over 7 years ago I saw it's first version. It was a horrible crash prone mess. It was a flight search bar with other value add addons. And yes it reported to the mother ship.

A lot of airlines did the same. So did package delivery companies.

I work rather closely with large companies that are deploying or have deployed improved analytics tools to track your every click. Big brother exists. An issue is it's not just one big brother.

Face book for example. Almost every single app is mining your account for information. Very use any of the facebook apps if you must use facebook. Only ever give the minimal amount of information. Remember you are the product.

If you are dumb enough to ever install a "toolbar" then you get what you asked for. There is no such thing as a free value addon. They will all cost you dearly.

Seriously, Filing court documents so they can destroy documents. The lawyers are simply bleeding the corpse dry. Anyone with a claim is just being stolen from now. OK well continue to be stolen from.

It makes me ill to think how much of a complete and total waste this whole battle was.

There should be a new category of crime. Like War crime. Lets call it Corporate Crime. The instigators and the abusers should be brought to very public tribunal grilled and if found guilty convicted and sent for hard time. These legal blood sucking crooks could be viewed as looters, pillagers, atrocity co-conspirators.

If this were to happen I would think that litigation in the US and across the globe would suddenly drop. Hopefully leaving behind legitimate legal cases.

Check the site at least and you will understand.

I've used PacSafe stuff many times. Basically all of my paranoia is gone when I go way over the top some times. I often use them to hold bags on motorcycles and when I just want to leave my heavy bag somewhere and keep it safe so I can do something more casual.

You can't use them for checked or carry on on a plane. TSA freaks out. You have to pack the packsafe stuff in a normal bag when on a plane.

I have no affiliation with pacsafe what so ever. I'm just a happy customer.
