In this process, wastewater flows through a series […]

The $1m electric asparagus  generator, hope or nope?

March 25, 2017


This turbine free wind generator sounded awesome, but will it work? Let’s play “Hope” or “Nope.”  Remember the fairly recent movie Ant Man? I refused to see it because it defied the laws of physics in an annoying way. Something very small that hits you fast doesn’t knock your whole body across the room as shown in […]

Wind power without blades

March 24, 2017


The piezoelectric effect turns physical motion into electricity. It doesn’t generate much, (apparently about 0.2 watts per unit,) but if you scaled it to cover the entire side of a large building, you could generate useful power.  To power a single home most would be self-sufficient (plus some to sell back) with 6 kW generator.  […]

Wind power can cover America’s total energy needs

December 17, 2016


In 1999, the US used 97 quadrillion BTUs, or about 18 percent of world’s total energy consumption. Sixteen years later in 2015, total U.S. primary energy consumption was about 97.7 quadrillion BTUs.  Unfortunately, the US lags behind Asia and Europe in renewable energy, with 90% of the energy the country consumes coming from non-renewable, unsustainable sources.  […]

Lightning is more powerful than we thought

December 12, 2016


Florida, for some reason, has more lightning strikes then any other US state. When lightning strikes sand, it creates rock formations that Matthew Pasek, Associate Professor of Geosciences, University of South Florida has used to measure the energy in  lightning bolts. One discovery from examining these fulgurites was that there are mega bolts. A big lightning strike […]

France decrees new rooftops must be covered in plants or solar panels

March 21, 2015


Rooftops on new buildings built in commercial zones in France must either be partially covered in plants or solar panels, under a law approved on Thursday. Green roofs have an isolating effect, helping reduce the amount of energy needed to heat a building in winter and cool it in summer. They also retain rainwater, thus […]

A map of human problems

June 21, 2014


I want something I can’t find on the net: a visual interactive map of human problems and where we are along the various paths to solutions. I want everyone to be able to interact with it, add to it, vote on it! We have all this information, so organize it! Who can help? Google? I […]

Solar Freakin’ Roadways

June 21, 2014


Not a good idea from an engineering point of view, but fun! For practical reasons we would be much better off building huge solar arrays across the Sahara desert, not to mention harnessing the tides. Tides are more predictable than wind energy and solar power. Among sources of renewable energy, tidal power has traditionally suffered […]

13-year-old builds working nuclear fusion reactor

March 8, 2014


Not many 13-year-olds would describe themselves as an “amateur nuclear scientist.” That’s precisely what Jamie Edwards calls himself. When most kids his age are off playing video games, Edwards stays late after school to work on a control panel for a nuclear fusion reactor. He just reached his goal of becoming the youngest “fusioneer” in […]

Clue to earthquake lightning mystery

March 7, 2014


Mysterious lightning flashes that appear to precede earthquakes could be sparked by movements in the ground below, US scientists say. Unidentified glowing objects were spotted moments before major quakes in China and Italy recently. These flickers could be triggered by shifting soil layers which generate huge electrical charge, say scientists. Using a tub of plain […]

Drilling surprise opens door to magma-powered electricity

February 8, 2014


… Can enormous heat deep in the Earth be harnessed to provide energy for us on the surface? A promising report from a geothermal borehole project that accidentally struck magma—the same fiery, molten rock that spews from volcanoes—suggests it could. The Icelandic Deep Drilling Project, IDDP, has been drilling shafts up to 5km deep in […]

Every Streetlight in NYC to go LED

October 30, 2013


When many people think of New York City, beyond the crowds their image of the city is the lights. Soon, the lit-up skyline will be much whiter because all 250,000 street lights are being switched to LEDs in the biggest retrofit project in the nation. The switch-over is part of PlaNYC, the city’s climate change […]

“Continuous” nuclear fusion comes one step closer

October 9, 2013


Researchers at a California lab have got one step closer in achieving self-sustaining nuclear fusion.
