What is a green technology that you would like to see invented?

It has to be green and can't exist already. You can upgrade an existing technology though.What is a green technology that you would like to see invented?
Well I forget what it's called but they found a living cell organism that uses sunlight to basically fuel itself. These solar panels are on their skin but they are so tiny (microscopic). We're finding a way to get their skins and use billions of them to actually use it like a solar panel. If we can keep doing that (while still not endangering that cell species of course, because then if they went extinct we wouldn't be able to use them anymore) then that would be a good way to harvest the sun's energy to use to light up homes.



(maybe it's not very effective [just lighting up that home] but still, it's easy to get, and if it's easy, well, we'll use it more.)What is a green technology that you would like to see invented?
More efficient engines are theoretically possible to build, it's just that no one has yet.

If it doesn't have to follow the laws of physics, how about a heat pump that takes in energy from the environment, concentrates it and runs it through a stirling engine to produce more power than it takes to run the heat pump in the first place?What is a green technology that you would like to see invented?
What a great question!



I think the most useful invention would be a fashionable and attractive electric car. At the moment electric cars are cost effective and sustainable but they just don't look the part.



I have heard about the Tessla electric supercar at, but I am yet to see one or hear of anyone actually buying one.



We have some cool vans, but had to change them considerably from their original state to make them attractive (and make them stand out for the nature of our business).



The other thing I would like to see invented would be an exercise generating mp3 player- the harder you train the more tunes you get to listen too! Not only completely green but a use of your energy and an incentive to stay healthy!
