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.
