Until now, acoustic or sound energy has not been used effectively to impose thrust or force on an object for purposes of providing useful work.
If you want to make a simple, quick change right now that will lighten the load on the earth and save you money, you can focus on just one thing: lighting. According to the International Energy Agency (IEA), 19% of global electricity generation is taken for lighting.
Dimming lights by 25% reduces electricity consumption by 20% and quadruples the life of light bulbs.
Small business qualify for the 30% solar and fuel cell investment tax credit, and receive 5-year accelerated depreciation, incentives for 50% lighting reductions, use of combined heat and power are now part of the House and Senate bills.
The new century oil and coal companies will "Grow" their carbon fuels in bioreactors using safe and cost-effective biotechnology.
Categorizing products as environmentally-friendly by sticking a symbol-type label on its packaging, insults consumers' intelligence.
So now you have a very simple device to guide people in making good parabolic basins for making solar ovens! I believe this type of simple device will help a lot of people to improve their lives.
It would take nothing short of a sea change to overcome Congressional inertia and recover the ground lost in the last 25 years or so. But though the prospects for a truly coherent national energy policy are improving -- and the need has never been greater -- both the citizenry and the current Congress are far too complacent to entertain changes that might involve belt-tightening and discipline.
Why not combine a flexible thin film photovoltaic module with a high performance coating, in effect creating a monolithic membrane system consisting of the coating and the photovoltaic both waterproofing the roof and generating renewable energy.
Just back from a whirlwind day at Solar 2007 in Long Beach and I gotta say ... this industry is on fire ... finally. On the show floor you literally had to elbow your way down the aisles.
Replace oil? How can something so monumental be accomplished? Preempt waste, start small, provide better service at lower cost and think better.
Using fuel cells in recreational applications means no more smoky emissions and loud operating noises from standard generators, as well as longer lasting power and easier refueling than today's batteries. That should make everyone breathe a little easier.
What strikes me most as a leap forward in terms of innovative, even disruptive, business concepts, is the installing of a waste-to-energy plant at the site of a power-customer itself.
The awareness of travel consumers is rising that our environment is worth considering. If the travel industry does not answer the call, voices will arise to discourage people to go to such idyllic places as the Caribbean.
Take electricity from the sun, run it through a charge controller and into a large battery bank. Have an inverter pull that power out of the batteries (when needed) and make it available as pure sinewave current. The trick: do all this inside of an enclosed trailer.

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
