Yes, of course, this is in the early stages, Mydesign. You might want to check out the message boards on this story--there is a lively debate going on! I am sure you would have something interesting to add.

Elizabeth, wait and see to know how much it practical and economical.

Hi, Mydesign, well, yes it seems very complicated, but a Navy engineer is working on it and he has already built a prototype for this type of thing. Here's the article I wrote: http://www.designnews.com/author.asp?section_id=1386&doc_id=272395


I would be really interested to know what you think.

"So perhaps it's not so far off that they can use solar panels in space to beam electricity to earth. The Navy wants to convert the solar energy to radio waves and then beam it via antennas on satellite modules. I think it could work!"

Elizabeth, am not sure about transmitting electricity from space station to earth through atmosphere. Lots of hurdles are associated with this type of conversion and transmission. It won't be economical too.

I wasn't aware of that, Mydesign, that's really interesting. So perhaps it's not so far off that they can use solar panels in space to beam electricity to earth. The Navy wants to convert the solar energy to radio waves and then beam it via antennas on satellite modules. I think it could work!

"actually today I am writing a blog post about how the U.S. Navy wants to build a space satellite with solar panels to beam solar energy from space, solving the availability/dependability problem. So stay tuned for that! Clever stuff."

Elizabeth, most of the satellites are equipped with solar panels & energy storing device for powering transponders. During day light they convert sun light to solar energy and stores in batteries for night usage.

Good points, Mydesign, and actually today I am writing a blog post about how the U.S. Navy wants to build a space satellite with solar panels to beam solar energy from space, solving the availability/dependability problem. So stay tuned for that! Clever stuff.

"Thanks for your comment, Al Klu. Actually the government is doing research and investing in solar and other alternative energies, and I agree that you're right they should be taking the initiative here."

Elizabeth, in most of the countries there are energy crisis and governments are always looking for alternate source of energy. Solar and wind are not always dependable because they are seasonal in most of the countries. In some countries they had developed hybrid systems, a combination of wind, solar, rain etc; so that energy can be produced throughout the year depends up on the available energy sources.

Al Klu, first am a non US citizen, I mean am residing in one of the Asian countries. For 3 KVA systems, all together the total cost is approximately $6000 and in that I got a subsidy of 60% (30% from State and another 30% from Federal government). As of now my total electricity bill comes to ¼ of the previous bills and I have the option to sell my extra power to grid. I hadn't connected AC and Pump motor to this system and hence paying these charges to the power supplying company.
