Solar Roadways Light Up The Future –

Solar roadways interstate at dusk

Yes, no snow shoveling or plowing. And the LED lights can be programmed for traffic lines, construction detours, warning sensors–any type of road indicator, so if a pedestrian was crossing a crosswalk, it could light up; if there an accident up ahead, the road could tell you; if you had to refigure a parking lot for a big event, you could reprogram the lines. And they could provide light at night. In the first phase of testing, Brusaw found that low beam headlights aimed at the solar roadway at night could generate energy in the solar cells. In addition to that, it can pay for itself by producing three times more energy than we use as a country? Most moon shots are hard to believe. In the very beginning, half the people thought we were geniuses, Brusaw says in a Focus/Forward short film by Michele Ohayan.

This Solar Breakthrough Could Make You Forget About Oil – Yahoo Finance

Some of the juice created by solar power (and wind, geothermal and micro-turbines) will be fed back into the grid, especially where two-way power meters are installed, but much of the excess power we generate will simply be uncaptured and frittered away. That’s why engineers continue to work hard to develop new ways to store energy, tinkering with virtually every kind of known battery chemistryand coming up with unusual ways to bottle up power for future use. [More from How To Profit From The $630 Billion Buyback Frenzy ] How bad is the problem? When clean energy sources such as solar or wind are producing peak power, they can create too much supply for grid operators, who essentially must give away electricity to shed loads. Storing that excess energy is the clear fix. “If that excess energy could be stored, not only would it not be wasted, but we could also protect the load factor and hence the economics of conventional (power) plants,” note analysts at Citigroup, who call energy storage one of the “Top 10 Disruptive Innovations of 2014.” These analysts speculate on a futuristic scenario that is a lot closer than you may think. They envision a home generating solar power, an electric vehicle in the driveway (with its own hefty energy storage device under the hood) and software that manages home loads. Your dishwasher would turn on when the car battery is full, but stay dormant while the battery is not at full charge. Many other examples of energy efficiency gains deriving from energy storage can be found at Sandia National Labs , including an interesting review of various new battery chemistries that show a great deal of promise in science labs. Energy storage has historically entailed high costs, but like solar, prices are dropping fast. For example, the cost of lithium-ion batteries has fallen nearly 90% since 2005, according to Citigroup, and they are likely to fall by half again by 2020.
