Answer
Advanced technology has made technically ever more sophisticated equipment available to us and the trend can be expected to continue. in many ways the goods are improving, sometimes dramatically (TV) but they mostly have a lifetime (with reasonably careful use) of around 4 to 7 years; then you need some service.
Sadly technology has also led to the virtual extinction of service notwithstanding that companies have telephone numbers for their service departments. If you try to actually obtain service from most suppliers or manufacturers (those for cars are a rare, surviving exception) you will be encounter so much difficulty that you will sooner or later give up and replace the whole product, which is actually the idea. You cannot even do the service yourself because technology has so sealed up or encapsulated the defective device that it is totally inaccessible and will be destroyed by any attempt to open it. Thus you will have to throw out a perfectly good razor only because the charger has failed!
For example - today's standard service - you try to contact the service department of a company! You will either get no answer, a little girl (she may be quite tall but sounds little) will promise to call you back but won't or you will be received by a recorded voice which asks you interminable questions and conducts you through a maze of criteria in which you make entries and choices by pushing numbers, and finally either leaves you hanging with some music (if you're lucky) or simply cuts you off so that you can start again. In such cases there is in fact no service at all, only the machine or the little girl who knows nothing about the company or any of its products.
Another (only a little less common) variant is the outsourced service. For some reason a company thinks it must offer some show of support (e.g. for software) so it sets up a telephone answering and technical support team in India (they seem to speak English and are very cheap). The staff will answer even your local call and they will be excessively polite and "helpful" to the point of complete frustration but in the end are totally incompetent. You will be led round different kinds of loop, e.g. trying to make direct contact into your PC, which after a half hour of fruitless tries has to be given up like all further attempts to understand, diagnose or fix your problem.
This is modern service - none at all! Ask for a service demo. before you buy anything expensive!

Does anyone have info about solar water distillers?
I see you
Is there a way to purify water using the sun's energy? An affordable method everyone could have?
Thanks you guys, I'd like to make a miniature one for ALL people to be able to collect rainwater, then purify it. I'll be researching your ideas.
Yse, Jim, I was trying to open a dialog where someone could come up with a way for peoples around the world to have access to their own drinking water derived from rain water. thank you all who responded, I "lerned" something already. Anyone else want to answer before Jim get 10 points?
Sorry about the spelling errors, everyone.
Answer
Water has the highest specific heat of any liquid below the molecular weight of 100 - it really takes a lot of energy to boil water!!! Using solar energy to boil water is certainly possible, but are you really interested in creating drinking water, or distilling water?
Someone in India needed an affordable way to make lots of drinking water inexpensively (I saw this on TV). What they came up with was a "germicidal" UV lamp and a shallow aluminum tray for the water to pass under the lamp, thereby "purifying" the water to drinking water quality by killing all the bacteria.
The germicidal lamp fits in an ordinary fluorescent fixture, and is very efficient on power. His task was to design the parts that would certify that all the bacteria was killed. The design will treat LARGE volumes of water economically; something a distiller won't do.
One more important point to consider: a true steam distillation process is intended to remove the minerals from the water as well as everything else. You need to think this through very carefully and research what happens when people drink (only) distilled water.
Because of difference between salinity in people's body and the distilled water, the distilled water will strip the electrolytes (minerals) from your body. This is not a good thing! If you distill the water, you'll have to add some minerals back before it would be drinking water quality.
This is why the bottled water at the store offers both drinking water (water with small amounts of minerals) and steam distilled water (for your steam iron, where you don't want any minerals)
One other person in Yahoo! Answers wanted to purify water using UV LED technology - UV LEDs operate at even lower power that UV germicidal bulbs, and could be driven by solar cell/battery combinations. UV LEDs are just now becoming available, and will soon be affordable.
This is assuming that the water you have is drinkable but just needs to be affordably cleaned of bacteria.
Water that is brackish or saline would need to be steam distilled, but that is expensive due to the energy required. There are other water treatments available (osmosis, filtering, dissolved mineral removal such as iron, hard water treatment, etc), but these cost money.
