My idea is based on a simple observation : so many people use good computers to only surf the web or to write on office! So the idea, linked to using computers to dig bitcoins, we could maybe assemble personal computers via a web platform so that all toghether form a supercalculator! The principle for a user would be simple : connect your computer to the dedicated website, it will be used by this website to calculate the weather evolution for instance, and you get some money for the use of...

These days the weather is getting hotter and hotter, and sun exposed cars are getting sizzling hot! What about using that heat to actually cool down the car (heat it in winter) ? That could be possible with a heat pump, any other ideas?

Are you found of skiing? Mountain bike? Runing? My idea is both to measure how much you moved, how intense your sports session was, comparing to friends, and so on, and to be able whenever you want to charge let's say your iPhone or your GoPro! How? For once this is not about piezzo (by the ways piezzo cost a lot of energy to produce and are very difficult to recycle), but a simple rotating device coupled with a dynamo just as the pendulum used in mechanic watches but bigger. Every...

The cellphone market has nowadays exploded, they are every year more performant, and also.. more demanding in energy. Knowing that we change of cellphone every 2 years in average, and that the cellphone battery is not obviousely the broken component (if there is one!), that is a lot of high tech batteries thrown away! My idea is to enforce renewable energy and their storage issues by storing the power into cellphones batteries.

Every year each person uses around 13'000 L of clean drinkable water only for the toilets! My idea is to promote he fact to reuse washing water fot the consumption of the toilets and save this way a lot of water.

Drinkable tap water before arriving to your kitchen goes to lots of pipes, and there 1/3 of this actual water leaks to the ground! 1/3 !! By changing the water network maintenance habits, we can drastically reduce this loss of water! For more details cf. the movie "water makes money"

When I hear about renewable energy, I always hear about solar panels, hydroelectric dam, wind power, bioethanol and so on but.. where hase gone the geothermal energy? This energy is the only renewable energy that is totaly constant through time, permits to save up to 75% of one's heating cost, has a fantastic potential, produces less than 15g of CO2 per kWh (ridiculous!). There is still technological barriers for the biggest installation, but more modest installation are totally...

Most of the houses and appartements still use fossil energies to heating, thermodynamically speaking and as a consequence for the environnement, this is a catastrophy! First of all, if possible, isolating the building (double windows, roof isolation) is the first big step to stop losing energy in building heating. Then, fossil and wood heaters are really not efficient as for electric heaters, a way to make the energy consumption for heating drop is to use heat pumps, geothermal energy...

Use the difference of temperature between day and night to produce energy, heat the house at night and cool it in the hot days!
