To Infinity and Beyond

Scientists are discussing, again, the possibility of solar arrays in space.


The complexity of such a project would be like the International Space Station and the Pyramids, combined. Nevertheless, engineers agree that it is technically feasible, albeit a few decades away from reaching fruition. The problem is the logistics, and the economics.

Now, I’m hardly one to dissuade people from making sci-fi come alive. We built the Hubble Telescope just so that we could behold awesomeness from billions of light years away, which we had no chance of seeing from the earth’s dusty surface. But solar power? Even here on the ground floor, we’ve already got enough sunlight hitting the Sahara to power the whole planet.

The primary customers for space solar power would be isolated regions who pay outrageous fees to import energy, or whose capacity to generate their own renewable energy is somewhat limited. There’s been some rumblings as of late about, of all places, the island nation of Palau becoming the first recipient of an orbital solar station. A company by the name of Welsom Space Power is negotiating with the government as we speak about having a 1.2 megawatt satellite in orbit by 2010, and an eight-megawatt orbiting power station by 2012.

The real appealing impetus here is to have an ambitious final goal, for which you develop amazing new technology. This dream may never quite see the light of day, and the resources spent just getting things up there would be colossal. But maybe we learn a few things in the process.

But what about all the creatures who’ll be cooked flying, unwitting, through the invisible microwave/laser beam that’ll likely be needed to get all this wonderful power down to the ground?

Hello,

These are low level ambient microwave fields at 10 Watts/m2(meter square) and 50 Watts/m2. Hardly enough to cook anything and in fact below the approved limit for leakage of microwave from your home microwave oven in the former case.

Microwave creates heat as energy loss from inefficiency of transmission and this is done on purpose in a microwave oven for cooking and not in WPT (Wireless Power Transmission) systems which can be over 90% efficient in converting microwave to DC pwoer. Your cell phone receives data from microwave fields very similar to those we use to recharge WPT enabled end user devices.

The sun at noontime radiates 1050 Watts/m2 so we are making microwave fields that are far below this level for both end user WPT devices and grid connected SBSP rectenna arrays. Some medical treatments for eye disease directly radiate over 100 Watts/m2 of microwave directly into the eye with no ill effects.

The systems we propose are for low energy level recharge of end user products in metropolitan areas. These WPT enabled end user products include WPT Rechargeable cell phones, WPT Rechargeable laptop computers and WPT Rechargeable Hybrid autos that require no plug in recharge or fuel in metropolitan beam down areas.

We are to begin discussion with Palau as such systems are very beneficial to remote areas and Palau provides a very good place for safety testing of Space-Based Solar Power (SBSP) WPT systems where the power can be put to good use in Coral Reef Restoration using BioRock Sea Water Accretion Process. We also seek to demonstrate environmentally compatible, new BioRock systems to make low cost building materials and hydrogen gas from the sea water electrolytic BioRock Accretion process.

We are also suggesting that the 1.2 MW Space Solar Array for Early Commercial Demonstration of Space-Based Solar Power also be tested with Laser + PV (Photovoltaic) WPT systems at the Victorian 154 MW Heliostat Photovoltaic Concentrator Power Station, Victoria, Australia. SBSP Laser +PV systems can augment the Victorian 154 MW Station during peak daytime energy consumption periods and also provide nighttime operation of the Victorian Heliostat using Laser from SBSP to run the power station at night.

No birds will get cooked I promise!

Happy Holidays,
