Default light up the earth, to save energy and increase safety

No thanks, I enjoy my rural night sky which on clear moonless nights can

it would save oil, make night driving safer, and could end at say
10PM, so night sky lovers would be accomidated.....


B.S. assertion. You're going to save a bit of money on lighting. This
will do nothing to reduce big users of energy (factories, air
conditioning, etc.) at night.

Besides, both oil and natural gas production in the US is actually
*increasing*. There is no need to reduce electricity usage at night.
That's a lower demand time of day anyway.

say create daylight savings time year round of the longest day of the
year

paid for by savings on oil


You're full of b.s. Where is your study which shows how much this will
"save"? It's got to be minimal. Sure, pictures taken from LEO of
cities lit up at night are pretty, but that does not prove that
streetlights are energy hogs.

Which is exactly why you should be asking Bob for the risk assessment
portion of his environmental impact statement for this project.

Bob you are prepared to write one? Right?

Dave




so exactly what are the risks? in detail please..........



normal night would be around 10 pm till 5 am, but in a emergency

daylight could be extended to even all night....



for true disasters like hurricanes etc. the daylight could help find

people etc


How is your mirror going to shine through the clouds of a hurricane, Bob?

More importantly, how is he going to get it up there and how is he
going to keep it oriented properly?

falcon or other commercial launcer, onboard solar panels would provide

So more handwaving and miracle robotic b.s. then? I suppose you think
these things will be "mass produced" unmanned toasters in orbit around
earth?

This has got to be the dumbest and most expensive "project" you've
"proposed" yet.

It would be far cheaper to invest in terrestrial based LED lighting for
street lights. The cost would be less, payoffs would be far faster (if
there is any payoff for mirrors in space) and the perceived risk would
be far less. Our town already switched to LED's for traffic lights.
They use less energy, last longer, and serve the same function. It
would be far cheaper to scale that up a bit to street light intensity
and start retrofitting street lights.

plants peak growing season are when the sun shines the longest and
britest. this could increase farm yield.

did you know many chicken and egg producers keep the lights on 23
hours a day so the chickens produce more...... the one hour of
darkness prevents them from freaking out during a power failure, and
dark is used to settle them at the poultry processing plant
immediately before they are killed
