  • I ride an ebike to work and to the grocery store when I feel like it and I think it’s great.

    I got a ride1up Turris. It tops out at 28 mph, which feels like a good pace on a bicycle. When the weather is nice, I use it to commute about 15 miles round trip to work, which requires about 0.4 kWh of electricity and a little over 20 minutes each way. This is compared to about 0.7 gallons of gas and about 15 minutes each way in my 20 year old truck.

    So, if I charge the battery half at home and half at work, I pay about 10 cents a day for energy for the bike vs about $3 a day for the truck.

    I hope lots of people start commuting on ebikes, given their decreasing cost. it would be a great way to reduce our carbon footprint and get a little exercise. It’s just the right amount of exertion where I feel like I get my blood flowing but don’t get to work all sweaty and gross.

















  • These antigens are mainly significant in regards to blood transfusions.

    People generally don’t create antibodies against antigens that they have on their own cells.

    If someone receives blood containing an antigen that isn’t present on their own cells, and their body has already created antibodies against this “foregin” antigen, this can cause a hemolytic transfusion reaction (the transfused blood cells will rupture in the recipient), which can be fatal.
