Hot water that never runs out & costs less — interested?

Heating water consumes a huge proportion of the energy used in most households.  Much of this energy is wasted because the water is heated & then stored until needed.  While it is stored, heat escapes, water cools & has to be heated again.

More energy is wasted because water is required at a range of temperatures.  Washing the dishes in a dishwasher requires hotter water than a shower.  Existing solutions heat water to a temperature too high for most purposes (wasting energy) & then mix with cold as necessary.

One solution is instant hot water.  I.e. heat the water only when it is required, eliminating heat loss from stored water.  Problem with previous systems which used this method was the huge power demand when the water was actually heated.

Solution: heat water, only when required, using microwaves.  Losses due to inefficient resistance heaters & hot water storage are eliminated.  Further energy is saved by heating water only to the temperature required.

Wind turbine disease fails to garner support from scientists

Vibroacoustic disease is an illness attributed to large amounts of low frequency noise claimed to be emitted by wind turbines.  Originally, the name was applied to a condition in aircraft engineers.

Claimed symptoms of vibroacoustic disease include psychological effects which vary from mild mood swings to psychiatric disturbances and digestive tract effects ranging from indigestion to duodenal ulcers.

Recently, a study of the existing literature failed to find any credible evidence to support existence of Vibroacoustic disease.  Hopefully, this is problem solved.

Samsung I9500 Galaxy S4 vs Samsung I9505 Galaxy S4: Double or nothing

Credit: GSMARENA

Samsung's Galaxy S4 is available with 2 different CPUs:

• GT-I9505 with quad-core Snapdragon 600 chipset; &
• GT-I9500 with Samsung's own Exynos 5 Octa chipset.

As has been reported previously on these pages, the Exynos 5 Octa has 8 cores in 2 sets of 4, one high processing power & battery consumption, the other low power & battery.  Only one set can be active at a time.  Idea is that, by selecting the best core set for each task, both processing speed & run time can be optimized.

In light of the above, why use the more conventional Snapdragon processor at all?  You may have read that the Exynos 5 Octa is incompatible with LTE (4G), so the Snapdragon would be fitted to Galaxy S4s in North America.

In the linked article, GSMARENA claims that:

• Snapdragon processors are being fitted in most markets around the world;
• both processors are compatible with LTE;
• production difficulties with Exynos 5 Octa processors is limiting their use;
• difference in benchmarked performance between the two processors is small;
• better battery performance makes the GT-I9505 model (Snapdragon) the better option; &
• talk time is much reduced in the GT-I9500 model (Exynos 5 Octa processor).
