The Thermo Acoustic Engine

Thermoacoustic experimenters have known for about ten years that as a stack (like the stainless wool) in a tube is heated at one end, it begins to sing because of the temperature gradient (hot to cold).

A Few Free Energy Devices that Work

A 7 year study of "free energy" devices, sometimes called "over unity" devices, was done to determine if any of these devices generated power by transferring energy from unknown sources and if so to determine where the energy was coming from.

Safer Backup Power With Solar - Using The Sun For Emergency Preparedness

With a little thought and preparation, you can solve many of your electrical needs safely in the event of an extended power outage. The do-it-yourselfer might want to make their own portable solar power supply, or put a 12 volt motor in a small swamp cooler to solve those electrical needs.

The Future For Solar PV (Photovoltaic) Energy

Solar energy is part of the solution and is a key to America's long-term energy supply. After all, fossil fuels have a long history of issues with respect to stability of supply and cost.

The Pulser Pump

Pulser pumps obey all the principles of E F Schumachers book Small is Beautiful. They foster independence and can help develop local pride and local infrastructure. They do not need outside tech support if they break down.

The Sun Doesn't Go Out

All the world really needs is a power supply that has no fuel costs, no pollution, and is available to everyone, everywhere, and relatively all at once. There is a technology which makes this possible today.

Advantages Of Electric Cars And Plug-In Electric-Biodiesel Cars

If the vehicle is a Grid Rechargeable (plug-in) capable hybrid electric-biodiesel (or diesel or gasoline) automobile, the car has all of electric automobile advantages for short trips plus the range & fast refueling advantages of internal combustion engine automobiles!

Automated Interior Plant Care And The Environmental Aspects Of Home Technologies

APM systems were developed primarily for container plants in furnished interiors, but can be used for many bedded installations as well. Large plants, small plants, dry-loving plants and moisture-loving plants can be serviced by the same system.

Electric Vehicle Recharging Network

You don't have to own an electric vehicle of any kind to be a part of the network. All you have to do is be willing to let others use the electric outlet of your home. Even if you are an apartment renter, as I am, you still might be able to let EV owners plug into an outlet of your apartment.

Event Preview - 'The Connected Home'

The Connected Home' event on 24-25 September, London, will offer a practical focused two-day conference on the real implications, strategies and technology challenges for the profitable implementation of the connected home.

Heat From The Earth

"Every time an expert tells me it can't be done, I sit back, peel one of my oranges, and marvel at my ability to eat something that is impossible to grow in Nebraska."

How To 'Make A Difference'

"if you ever thought you are too small to make a difference in this world try going to bed with a mosquito" - Anita Roddick (founder of the Body Shop)

Impact of Power Consumption On Consumer Electronics

Consumers are demanding - and advances in semiconductor technology have enabled -- bigger and better color screens, more intuitive user interfaces, faster performance, more wireless interconnectivity, and smaller and more portable form factors. This means that for the same battery size and battery lifespan, all types of electronic products must take advantage of low power semiconductor devices in order to incorporate more features while consuming less power.

Product Review - Touchscreen Wireless Weather Station

The system keeps track of indoor and outdoor temperature and humidity, wind direction and velocity, solar intensity and rainfall. All of these variables are displayed on a very elegant touchscreen panel that can be wall mounted or set on a table. The display also shows the time and date and has a graphing feature that lets you view the history (last 24 hours or last 8 days) of any of the variables at the touch of a finger.

Safer Water With Solar

When I give seminars to school age children on solar cooking I usually see a student with a clear bottle of water and I ask them, "did you have to get that water out of a river running behind your house? Did you have to dig a hole in your yard to find that water?" They laugh. Millions around the world have to get their drinking water every day that way.
