   For one, this could reduce maintenance costs for solar panels substantiality.

   For a notebook you still want to reduce energy usage. All that heat has to go somewhere and a hot device and loud fan are very annoying. Apart from that, I agree. Any of this new battery types will first be used in small, high priced device

   I agree, though, zero sales tax certainly plaid a role, too.

   Good point, but if you don't need to handle unstructured terrain, you might just as well put the robot on wheels. The humanoids robot Justin from DLR [1] for instance has an omnidirectional wheeled platform that even allows for adaptive foo

   Boston Dynamics robots like Big Dog use hydraulic actuators [1] which act somewhat like a spring and are hence very robust towards perturbations. They also have more power (= force*velocity). ASIMO in contrast uses an electric motor with a

    The reason for this, is their control algorithm. It uses a inverse kinematic to compute the desired motor commands in the joints. When the legs are stretched out, it is in a singular position where the resulting motor gains would be infinit

    I agree. Usually, on HN the title shouldn't be changed but here I should have made an exception.

    If this is open source, where can I find the source?

    Nice, but what really remarkable about the German project is, that it is completely electric and battery powered. This should be the first battery powered non fixed wing human flight ever, no?

    Do you also have the necessary capital behind it? Hardware companies need a lot more financial investment.

    Do you have a source for this? I find this weird. Wouldn't more food for Anopheles increase their population and hence the risk for humans to get bitten?

    I've been wanting to build a company out of this idea for over 6 years now. Problem is you need a lot of capital from the very beginning.

    Removing the cost of the driver will have an tremendous effect. It will bring down the cost of a taxi ride near to the cost of driving with your own car (plus the way the car had to drive to get to you). I have big hopes, that this technol

    As far as I understand, unless we develop reliable fast breeders, there is hardly enough fuel for that many nuclear plants. I thought the Japanese were on a good way to build an energy economy based on breeders. Now, these efforts might be

    So how much forestation would be required to reverse a significant part of the effect of the industrial revolution? Lets say the CO2 emitted in the last 30 years. Would there be enough vacant area on earth to handle such an amount of forest

    You got banned after changing your last name? Are those bans done by hand? I know, that they have a real name policy but so has Facebook. A lot of my friends and family changed there real names into fake names on Fb. Nobody got ever baned.

    I would be interested in the history of that. Homeownership seems very American to me, but subsidizes not so much [1]. And books or links, that you can recommend? [1] I'm aware there are many subsidizes in the US, for instance in agricultu
