"The efficiencies of good modern Otto-cycle engines range between 20 and 25 percent (in other words, only this percentage of the heat energy of the fuel is transformed into mechanical energy). "75 to 80 percent of the gasoline we buy is wasted due to the inefficiencies of the internal combustion engine. The heat energy generated by our brakes is also wasted. If our cars could use that brake energy we could cut our gas consumption dramatically, especially in city driving(this is why hybrids get better mileage in cities). The only energy loss would be from rolling resistance from our tires and from wind resistance.
"Electricity ranges from about 5 - 10 cents per kW, so a gallon of gas (more than $2) has as much energy as $1.65 - $3.30 of electricity."At first glance it looks like gas power and wall power are the same price but gas engines are only 20% efficient so using a plug from the side of your house would be 5 times cheaper.
On tombe parfois sur des commentaires amusants sur les blogs remarquant avec consternation que Bill est tombé sur la tête. Un exemple :
Il y a une vieille histoire qui dit que le gamin qui casse des fenêtres de voitures la nuit pendant que ses voisins dorment est une bonne chose pour l'économie. Les fabricants de vitres de voitures font des affaires, des emplois sont créés, le PNB augmente, donc tout le monde y gagne, non ? Ca n'est bien sûr pas le cas, mais on dirait que c'est la logique que Gates utilise. Et pour cause, ça fait bientôt 20 ans qu'il casse

One falls sometimes on comments amusing on the blogs noticing with consternation that Bill fell on the head. An example :
There is an old history which says that the kid who breaks windows of cars the night while its neighbors sleep is a good thing for the economy. Do the manufacturers of panes of cars make deals, employment are created, the GNP increases, therefore everyone gains there, not ? Ca is not of course step the case, but it would be said that it is logic that Gates uses. And due, that made soon 20 years that it breaks
Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates:If you skipped over the techno speak it just means that you don't have to wait for things to finish before continuing to navigate the site. The result is things like the new Google Maps project. This link shows a map of my cross street. The neat thing here is that you can drag the map around like you can a window on your desktop. I used to refer to this as Open Source Middleware but it's bigger than that. It's the end result of digital technology and standards. Standards are finally coming together enough to see it happen.
