Imagine that you can install curtains in your house that will absorb the sun's light and convert it into energy. This is not science fiction; it is a prototype of the "Soft House," a concept in energy production designed by Sheila Kennedy, an expert in the integration of solar cell technology in architecture.
The "energy harvesting textiles" can generate 16,000 watt-hours of energy, about half of a compact home's daily needs. This has incredible applications in any number of structure where curtains can be used. Its cost is currently prohibitive, but as we all know, these things lead to more innovation. Remember when the average computer needed a whole room? Those ancient dinosaurs didn't even have 0.00001% of the RAM present in today's average PCs. Now cellphones are thousands of times more powerful than the early computers.
