Clearly, EREBUS has asserted that we would be better off without half the population of California. Perhaps that is not his photo.

Clearly, EREBUS has asserted that we would be better off without half the population of California. While it is true that a lot of them seem to have stayed out in the sun way too long, that is a socially and politically incorrect assertion. OH WELL!

An extraordinary thinking in the year 1966. Based on this many other novel ideas can be arrived at.

Enough rain falls every day to supply the worlds need of water for a year. If people are too stupid to live where rain does not fall, I think we are better off without them in the gene pool. There are many ways to conserve and reuse water. The key is to adapt your use to your supply. If you exceed what you have, then you are not paying attention. Just my opinion.

Reads like another perpetual motion machine to me ;-) Nothing is as simple as it seems, putting the temperature concern aside, frozen pure water may offer some benefits, but the problem is that water in its natural form, contains a level of mineral content, that generates all kinds of deposits with time, has anyone had to replace home plumbing, or had to clean up the shower head?, and noticed the mineral deposits built with time. Good intentions but many other methods are been explored, from filtering salt water to better filtration mechanisms at a more local level.

Well actually he did. He claims that the energy required is considerable and that because he is using natural forces (gravity, earth spin etc) he would need little to no energy input. However, it seems to be that he assumes the ice balls will not melt plus I think there are a number of other issues with his calculations.

The energy required to transport the water would be better employed in desalination of local water. Didn't think of that, did he?

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
