Unethical to send people on a lonely, hazardous journey? That may be, but to send a solitary craft with a small number of explorers borders on simply bad planning. It is a plan which does not include redundancy. Sending a small flotilla, with multiple crews, capacity to transfer personnel between ships, and capacity for each ship to carry the whole expedition human crew, would provide redundancy in the event of a ship or ships becoming unserviceable. It would mitigate the boredom/loneliness problem, and increase the probability of the whole crew being able to return safely. Space is dangerous and things go wrong. The Apollo series demonstrated that. Early explorers learned to take several ships to increase their chances of survival.

So PV more expensive to maintain than thermal or hydro power stations? Point me to your facts. when a thermal station goes down, that's a whole lot of adjustment the whole grid has to make. A PV cell or panel? Give me a break...

Water pumping is slow. Hydrogen is fast, esp when it is being used dynamically at the receiving end. I would suggest that hydrogen does not need to be stored at the receiver the way water is currently for potential energy. And it is potential energy that we are talking about. The problem becomes a much more dynamic one.

rethink your costs. you do not need to store water and pump it uphill. You store hydrogen close to the coast where it is made, and pump it uphill at much lower cost than pumping water, to the existing power stations and their existing power distribution grid feed points. Then use fuel cells/gas turbines to generate, 24 hours per day. Countries like Denmark with low sunlight flux can import bulk hydrogen from countries closer to equator with low cloud cover fraction.

The last time I measured it, sunlight was $0 per. What are you talking about?

What is the evidence that the process which produces the neutrino flux is contemporaneous with the process which produces the light burst in a collapsing star?

Indeed sadness comes with the passing of a courageous writer. Courageous because he attempted the difficult feat of overtly connecting the strange erotic and violent internal world of unconcious (and not so unconscious) fantasy with patterns in and products of human civilisation. His more surreal and difficult work sometimes proposed that the human condition, if not genetics, were somehow pre-ordinately composed with information which could be expressed biologically, in not always adaptive ways, to socially or environmentally bizarre changes and crises. His melding of the more basic human urges with technological sophistication drew a range of extreme responses amongst avid readers and critics, which perhaps suppressed a wider appreciation of some of his predictive ability and linguistic adeptness. It could be argued that a proportion of his surreal writing was a product of the horrors he witnessed in concentration camps as a child, but if so, he took a long time to tell his story in direct terms - in 'The Empire of the Sun'. But even if so, we have been enriched by his foretelling of perspectives on humanity in allegory which few others have attempted. Vale, to a generous story-teller.

Still 10 billion shipments behind ARM.

"Edison's Pearl River Power Station started up its generator on September 4, 1882, in New York City. About 85 customers in lower Manhattan received enough power to light 5,000 lamps. His customers paid a lot for their electricity. In today's dollars, the electricity cost $5 per kilowatt-hour!"
