Not your normal umbrella, the sensing umbrella will respond to the level of air pollution in the area with a series of LED lights while helping track air quality. The Arduino-equipped sensing umbrella will be able to gather pollution data and upload it to pollution databases, making it possible to generate local pollution indicator maps for smaller regions. The umbrella's LED lights will also provide a more immediate source of information as they will flash and change color...

Although I'm a true fan of recycling, I hate glass containers. There's one in my back yard, and every time someone throws in a bottle, I can hear it in my entire flat. Even worse, there's a bar on the same block where I live, and every morning they dump last night's bottles into the container, I simply fall out of bed. I've spoken to the local trash authorities about this problem, but they say they have experimented with silent glass containers in the past, and that it can't be done. I...

Take advantage of excess electrical production capacity during night-time hours by equipping homes and businesses with large battery systems. This approach has been suggested for electrical cars where the disadvantage is the size of the battery system, but this would be much less of an issue for homes and businesses. Power companies would need to provide a cost incentive to encourage the use of these and the energy storage mode would be best controlled remotely by centralized operation at...

The reservoir in your toilet is much too large for the quantity of water needed to flush out the contents after use. Suppose if everybody put a red brick in the bottom of their reservoir how much water that would save!

There's many people that think CO2 is bad, but what they don't know is that there are things in nature that have to have CO2 to survive. Did you know that algae consumes more CO2 than trees and the toxins let off by coal burning factories are nutrients to some algae's? The nutrients that the algae then produces can fight and prevent malnutrition and when dried, the algae becomes biomass and can be burned like coal for energy with no emissions. I propose that all coal burning factories, by...

I was reading how in certain places if two tall buildings are built close together they trap wind and send it rushing through the passage between them. My idea is not to build turbines between skyscrapers as is often suggested but to build structures outside cities whose sole purpose is to trap wind and send it rushing through a narrow passage in which there are numerous turbines. The turbines can be built into the structure so only the actual turbine bit sticks out. Given how much...

A hydro turbine parallel to the Panama canal is feasable if there is a significant difference in height between the 2 ends.

The SolarTech is a solar satellite aimed at the sun 24/7 much like a tv or radio satellite. It works by sending radio signals to a receiver. It picks up the signal and makes the (car, house, computer, ANYTHING WITH THE RECIEVER WORK). And could take over gas, electric, nuclear, batteries, etc. And nobody would ever need those things again

This one's especially for California - I have had this idea for years: As the waste water approaches the treatment plant, have it hit by a ring of laser beams. This will create steam which will turn the turbines to make the electricity. What remains will be germ free but good for topsoil, making soccer fields etc...

You could, potentially, run anything from a car to an air plane with this. Any toy could use it and it would be environmentally safe and safe to eat. You could use it anywhere, at any time much like making beer but, with an immediate reaction. You can use baking soad and vinigar but, you don't get hours of energy from that. A very easy, inexpensive, all purpose energy source for any, possible, imaginable use, within reason.
