Wind power is one of the few green energy sources that has really caught on, but most wind generators simply dump their power into the existing electricity grid. But what if you want power in a place that's off the grid? This concept called the Portable Power Center from Uprise Energy could provide the answer.
Wind energy is some of the cleanest energy there is. It's relatively cheap to produce and easy to install, and produces power fairly reliably. So, but what happens if we transition to nothing but wind power? As dumb as it sounds, will we run out of wind? The answer seems to be "probably not," but there will be consequences.
Just how big is massive? The latest wind turbine blades being built for offshore use are gigantic — roughly the total wingspan of an Airbus A380. They are the longest wind turbine blades being built, and here's how they do it.
I'll bet you didn't know that aluminum (the same stuff that keeps your soda in the shape of a can) has more than twice the energy density of gasoline. Combine powdered aluminum with water at high temperatures, and you'll get heat, hydrogen and aluminum oxide. In other words, you get enough clean car fuel to take you 1,500 miles per tank.
Architects Joshua Bolchover and John Lin's Rural Urban Framework (RUFWORK) project seeks to "engage in the rural-urban transformation of China." The team constructed a self-sufficient rural farm house that has been designed to provide natural ventilation, collect rain water, and create power from pig feces.
Every year the Shell Eco-marathon presents a global competition for student teams to create novel vehicles that "travel the furthest on the least amount of energy." One entry from Aston University has taken the renewable vehicle concept to another level of wacky, forward-looking green design.
Engineers have long known that a double-sided solar cell design would increase cells' overall harnessing power. The main barrier to creating such a double-cells was an economic one. However, one solar startup claims they have figured out a way to tweak the production process to make "bifacial" designs economically feasible.
A few years ago, a 10 million watt wind turbine was built in Norway. Now, heading in the complete opposite direction, Scotland installed a 100-food 1-megawatt turbine under water, off the coast of Orkney.
Back in March, we posted about how this could be the year where the National Ignition Facility breaks even with laser fusion, reaching the point where as much power is generated as is input. This doesn't mean we've got a fusion power plant around the corner, though, and researchers have come clean about what the hold-up is.
Here's an attractive solution to the problem of gathering energy offshore: Harness both wind and wave power at the same time. A company named Floating Power Plant plans to build Poseidon 37, a 754-foot-long floating power generation station that can...
