Wave Energy: Latest Systems Improved
MIT researchers are working with Portuguese colleagues to design a pilot-scale device that will capture significantly more of the energy in ocean waves than existing systems, and use it to power an electricity-generating turbine.
Best to Worst Energy Sources
A recent study by Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford finds that Wind, Water and Sun Beat Biofuels, Nuclear and Coal.
A Green Snowblower
To continue my migration to all things green, my big, heavy, smokey snowblower has find it’s new home under my deck. Yes, I might have to get some exercise this winter.
Here in New England we expect anywhere from 75 to 120 inches of snow each year, and it needs to be removed from driveways and sidewalks. In true American style, we have built some monster snowblowers, to do the heavy lifting for us. Gas powered, noisy, newspaper eating, propellors throwing the snow 30 feet in the air. Fun, yes. Green, no.
Clean Coal ?
Please stop talking about Clean Coal as some kind of solution for energy independence and/or global warming issues. It can not do either of these. Let’s use some common sense. Coal to replace gasoline ? Coal to replace home heating oil? We could build more coal fired electricity generating plants, but that does not reduce our dependency on foreign oil for the other two needs.
Residential Geothermal – Here now. Is it Cost Effective?
The idea, which is being proven effective every day by companies like Climatemaster and Waterfurnace is a real choice for new construction, public buildings and upgrading your home system.
The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50°F to 70°F depending on geographic location. Working with an [...]
Battery Powered Lawnmower
My next investment is a battery powered lawnmower from a company in Vermont, called Neuton Power Equipment. I am awaiting arrival of the 19″ mower. This is a new model, most to date, have been smaller in width, 16″ and under powered. This makes it more work to mow the lawn, more passes across the lawn, even more frequent cutting because it can not handle the longer grass. I hope this model can fill the bill.
Reduce gasoline consumption by %50 – NOW!
The study below says if all cars in the US were plug-in fuel cell hybrids we would reduce our gasoline consumption by %50. This is with existing technology and would be about one thousand more on top of the currently available hybrid technology (for the fuel cell piece). A lot of research went into this [...]
