Technology increasingly impacts the way we live. We’re not talking about the WiFi devices that allow you to control your home from wherever you are, or a personal camera-toting drone – those are already on the market for under $200. Here are three technological developments which seem fated to have the same level of impact on our lives as the personal computer.

A group of Australian students and their new electric car prototype might give Elon Musk’s Tesla S a run for its money.
The Sunswift eVe went 310 miles on a single battery charge in a July test run. In contrast, the Tesla Model S can drive anywhere from 244 to 306 miles on a full charge.
And, it’s fast, too.

Car-pooling is great, if your co-poolers don't drive you crazy ... but pooling has rolled down that long lonesome road to a new stage of evolution: car-sharing.

Good green policies like bike-ways, pedestrian friendly streets, increased transit, decreased freeways and car use, composting and recycling, urban food production, stream rehabilitation and green space protection can make all our lives better.

I had just read an on-line opinion article with my morning coffee entitled “Greenest city moniker an Orwellian nightmare” written by Harvey Enchin, and published in the Vancouver Sun.
Mr. Enchin had started his article with the statement that “… Green economies don’t create wealth, but dissipate it, which should send a shudder down the spine of every person in Vancouver” What on Earth had sparked Mr. Enchin’s ire, I wondered?

How about harnessing gravity to drive electric trains? What if every axle on the train was equipped with a generator that automatically engaged only on the down grades, assisting in braking, while producing electricity? Trains already have axle powered generators producing far more electricity than is required throughout the train, maybe the

In choosing an electric bike there are several important considerations. First, decide how far you would like to go before the battery needs to be re-charged, how much you want to contribute with pedaling, how much you will save on car mileage and parking, and thus how much you are willing to invest.
