New miniserver incoming

This isn’t really EV stuff but it’s a bit ECO-friendly. I’m building a mini server for some home use, based on the INTEL D945GSEJT AtomN270 mini-ITX motherboard which has a estimated power consumption as low as 20W with a ordinary hard drive. I’m going for a completely silent system with no moving parts, therefor the harddrive is switched out for a 16Gb CF card. More when the motherboard arrives!

Ps. a 60W power supply and the CF-to-SATA-adapter is on it’s way from china…

Homemade Electric Bike

A friend of mine told me he has something to show me, and later arrived on his…

Homemade electric bike! A really impressive build with it’s 1000W (yes three zeros) motor and regenerative braking. Currently powered with lead acid batteries but LiPO might be on the way in!

Check out his blog here and the bike here.

Local library goes solar power

Saturday, May 16th, 2009

Read a notice in the newspaper a while ago that my local library was going to install solar panels on their roof. No numbers was mentioned else than the calculated power generated in a year would be enough to power 5 villas just as long…

Then I visited the library when I worked (furniture delivery) and saw this sign, displaying current generated watts, total kWh today and MWh since installation. When I took this image it was cloudy with a fine rain and they still generated over 8kW!

ECO Power, taxes spent well.

Eva Håkansson - The AmericaSwede with a EV MC!

Saturday, January 24th, 2009

Since I started looking at ways to add range to electric cars by optimizing air flow, weight and drivetrain, the main idea has been to keep it simple, small and light. Then it struck me, a motorcycle would be perfect for this! And since it’s smaller the cost is lower to!

But someone has always been there before and in this case it’s Eva Håkansson. She’s currently involved in building the worlds fastest motorcycle and she has built an EV motorcycle with her father. This EVMC goes about 80 km (50 miles) at 70 km/h (44 mph) per charge.

The Solartaxi adventure

Sunday, January 11th, 2009

Wow, the solartaxi is a really nice little thing.

Going 100km per day on the charge from the onboard solar panels and a lot more when charged from the grid. To be fully solar powered the team behind the solartaxi built a solar power plant in Switzerland that feeds electricity to the grid, so that the charging of the solartaxi doesn’t affect the need for coal powered power plants…

Read more at the solartaxi website.

I would like to build a similar thing like this, but more like a streched minivan that two can live in and then travel around the world in a green way.
