Love it, indeed
Really good solution

This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

US Navy Explores Beaming Solar Power From Space

RATE THIS! +31
Posted in Science on 27th Mar, 2014 01:26 AM by AlexMuller

A major complaint about renewable energy sources, including solar power, is that they don’t generate energy all the time. At night or during cloudy weather, solar arrays don’t produce electricity. But it’s never nighttime or cloudy in space, and the U.S. military is taking steps toward creating a solar array larger than the International Space Station to orbit the Earth.

 

The Naval Research Laboratory has built a compact solar module capable of capturing and transmitting solar power from space. One side of the tile-shaped satellite features a photovoltaic panel. Inside the tile are the electronics that convert the resulting direct current to a radio frequency for transmission, and the other side supports an antenna to beam the power to Earth.
 
The panels performed well when tested under space-like conditions.
 
But they are just the building blocks of a much larger plan. Enough panels to stretch 9 football fields would be launched into space and assembled and attached by robots. Supported by a module to collect and reflect sunlight, the array would convert direct current into a radio frequency and send it to massive receivers on the ground.

Energy resources remain number one problem and a big factor in any consideration what the future could bring. This seems to be a very good idea and I hope could be made feasible

Indeed, the biggest problem is the cost. The main cost is related to getting things to space. "That’s why NRL has honed in on modular tiles that could be assembled by robots once in orbit." Reply

Some believe that we should build this solar energy generator here on Earth. It is suggested that it would be feasible and even cost-effective to do so. Reply

This is a very good news for all supporting efforts to protect the environment. With cleaner energy sources, climate change would be attenuated! Reply

I did not get the flu shot. I have only gotten it once in my life I think. I would say that I don't nolrlmay get the flu very often, but I realize that that means I could still carry it. I know that a colleague once told me that the reason we no longer die from the common flu like people used to in the 1800 s is because enough people get vaccinated now that it has controlled the virus. Therefore, if everyone suddenly decided not to get it, it could become a much more serious virus like it used to be. I know this means that I should do my part and get it too, but I don't like the idea of injecting something foreign into my body. I might consider getting it next year now though after thinking about this again. Thanks for the info, it was insightful! Reply
