A DIY E-bike Conversion on the Cheap

Cars That Think

Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load. With the power setting fixed, the wheel would spin increasingly fast and the amperage drawn from the battery would steadily increase.

Build a Passive Radar With Software-Defined Radio

Cars That Think

But it was the KrakenSDR’s ability to do passive radar that really caught my eye as a new capability in lowish-cost radio tech , so I plonked down the money. This was in a bid to shield the antenna from the reference signal and myself from the wind. The next step was to get suitable antennas.

MIT Battery Breakthrough Could Revolutionize Electric Cars : Gas 2.0

Tony Karrer Delicious EVdriven

7 Uncle B said on April 14th, 2009 at 10:17 am This battery is going to absorb peaks from wind-turbines, hitherto dumped to prevent damage to lines! A really significant efficiency increase will be realized, and in combination with the new “variable&# alternators from Vancouver, Canada, major wind power efficiencies can be anticipated!

Best speakers ever

Electric Auto Association

Electric Auto Association Silicon Valley (EAASV), established in 1967 as the original Electric Auto (now Vehicle) Association, has a long history of attracting members and presenting speakers who have gone on to become tech and transportation luminaries. More recently, Gage became the CEO of EVGrid , working on Vehicle-to-grid (V2G) tech.

Dodge Circuit EV First Drive: electric car makes grand promises on Earth Day

Tony Karrer Delicious EVdriven

Well need to spend some more time with the car to find out how it holds up over longer drives, but the powertrain tech obviously works. In California, 20% of our electricity comes from zero CO2 renewables (sun, wind, geothermal), another 20% from zero CO2 hydro, and only 20.1% to decide if we ever get to see these promises fulfilled.
