Ways to Save Earth: Pulling CO2 From the Air to Make Gasoline

I hear a lot of dismay out there about the environment, but I believe there is still hope for the planet Earth, that we might even reverse the ongoing Holocene extinction if we humans stop squabbling and really get our act together. As one great example, it is said to be possible to undo the greenhouse effect we have created by extracting CO2 from the air in order to reverse climate change. The technology already exists, in fact, it just needs to be scaled up. From its pilot plant in Squamish, British Columbia, Carbon Engineering has successfully developed and demonstrated … Continue reading Ways to Save Earth: Pulling CO2 From the Air to Make Gasoline

Flexible Sweat-Powered Biofuel Cells

True Strange News: Have you ever thought of human perspiration as a biofuel? A stretchable sweat-powered biofuel cell can now run an LED light. Bioelectrochemists from France collaborated with a University of San Diego team in California who are experts in nanomachines, biosensors, and nano-bioelectronics. Together they developed a flexible conductive material consisting of carbon nanotubes, crosslinked polymers, and enzymes joined by stretchable connectors that are directly printed onto the material through screen-printing. Issue 43 of the Journal of Materials Chemistry shows that this work has been ongoing. “Wearable textile biofuel cells for powering electronics” was published in 2014 includes … Continue reading Flexible Sweat-Powered Biofuel Cells

NASA: A Nuclear Reactor To Replace Your Water Heater

In the future you may have a safe low energy nuclear reactor to power your home, or at least to heat your water. This is one suggestion by a NASA scientist several years back. Nothing came of it so far on the consumer market, but it is a strange idea still worth considering. NASA scientist Joseph Zawodny with a device used to test low-energy nuclear reactors (NASA) This reactor does not use fission, the process of splitting atoms into smaller elements employed by every commercial power reactor currently operating on earth. And it does not use hot fusion, the union … Continue reading NASA: A Nuclear Reactor To Replace Your Water Heater

Unlimited Pollution Free Energy with Graphene Wires?

It is strange that we still pay others for the energy we need to cook, to stay warm and to power our vehicles. Is a clean solution to our energy problems right under our feet? An amazing property of graphene wire is that it transmits heat quickly, even for miles, ten times better than copper. It is also 200 times stronger than steel and six times lighter. Theoretically, graphene wires sunk miles into the earth could safely bring up geothermic heat for all of our energy needs, pollution free. This video has this pitch and a few more including tidal … Continue reading Unlimited Pollution Free Energy with Graphene Wires?

Video: Energy Generation From Nitinol “Alien” Memory Metal

“It almost looks like perpetual motion.” – Quote about a working Nitinol Engine. One of the memorable things reported at the famous crash in Roswell, New Mexico in 1947 of, supposedly, one or more flying disks, was a super light weight very strong material that returned to its original shape when bent. Major Jesse Marcel, who everyone – believers and doubters – acknowledges was at the crash site, said decades later: “I saw a lot of wreckage but no complete machine. It had disintegrated before it hit the ground. The wreckage was scattered over an area about three quarters of … Continue reading Video: Energy Generation From Nitinol “Alien” Memory Metal

Invented: Urine Power that Kills Bacteria

Here are two practical ideas implemented in one human waste processing system: Researchers have developed a system which can generate electricity from urine — enough to charge a mobile phone — and also kill bacteria harmful to humans, an advance that could be harnessed to treat wastewater. In this process, wastewater flows through a series of cells filled with electroactive microbes that attack and destroy pathogens. The researchers believe that the microbial fuel cell (MFC) technology could one day be used in developing countries in areas lacking sanitation or installed in homes to help clean waste before it flows into … Continue reading Invented: Urine Power that Kills Bacteria

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

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 the Ant Man trailer; it makes a hole in you, splats on you and stings, or bounces off. I have that same feeling with this bladeless windmill, making the motions it does and supposedly generating meaningful energy.  VortexBladeless has collected over a million dollars and Ant Man … Continue reading The $1m electric asparagus  generator, hope or nope?

Wind power without blades

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.  How big a structure would you need for that amount of power with this technology if you had a sufficiently windy space? Here are some numbers: … This project proposes to put panels of about 250 four-inch oscillators per square meter on the sides of … Continue reading Wind power without blades

Peer-to-peer energy trading networks are growing

Here’s a great idea that is spreading, power to the people, from the people.  … In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door. The project is still in its early stages — it has just 50 participants thus far — but … Continue reading Peer-to-peer energy trading networks are growing
