Another new aircraft design has been introduced by a joint team of researchers
from MIT and Cambridge (UK) University. The plane incorporates several innovations. First the engines on top of the craft, rather than
under the wings, as is currently the norm. This helps make the www.aumm.nl
3000 times more quiet than a conventional passenger jet.
This craft, dubbed the SAX-40 design is
also "35% more fuel efficient than any airliner currently flying."
The design is a radical departure
from current aircraft. The new craft is http://seyonic.com/buy-real-viagra-online-without-prescription wedge shaped, rather than the
familiar tube configuration of current airliners, with the wings extending
from that shape. This contributes to canadian pharmacies online cialis the efficiency of the craft, however
this also makes it more difficult for aircraft manufacturers to build
shorter or longer versions of the same plane without redesigning the
entire vehicle. Maintenance would also be more difficult because the
engines would be less accessible to ground-crews.
Even if these obstacles can be overcome, the earliest this airplane might
come into service is expected to be around 2030. By then, hopefully the things will run on hydrogen, and we won't have to worry so much about fuel economy.

When we first saw them we thought they were cool, but now that we've seen a review (at TrustedReviews.com
) we're definitely getting some USBCell Batteries
for ourselves. They are amazingly convenient, requiring no charger, just a USB
port. They hold their charge well, charge quickly, and have enough stamina to take over 500 digital pictures with a Fuji Finepix
I should remind everyone that you get better efficiency out of a wall
charger, because the current doesn't have to go through the
inefficiency of enter site levitra uk
your computer's power supply, but it also doesn't suck
power from your wall when there's no batteries plugged in. At $24 for a
pair of AAs
, it's a bit expensive, but well worth the price if you ask me.
Dell is now recycling everything Dell makes
...for free...no matter
what. You don't have to buy a new Dell, you don't have to pay for
shipping. You just send it to i recommend viagra online usa
them, and they re-use or recycle it. The best part is that a lot of the materials, if not the
components themselves, will be immediately re-used, not just recycled.
The effort that Dell is putting into ensuring that it's production
cycle is circular, and not just a straight line from the cialis online shop uk
mine to the
dump, is extremely important. Frankly, they're making every other big
electronics company look pretty darned bad.

EnOcean is developing micro-power sources that derive energy from
ambient conditions including light, vibrations, and temperature
differentials. These little power sources should be enough to power
peel-and-stick electronic devices including RF transmitters, sensors
and switches. Deriving power from ambient light or heat could allow a
house to be retrofitted with new light-switches, volume nobs,
information displays and theglobalobservatory.org
sensors without re-wiring anything. There
could be one RF transmitter in a lightswitch, and a receiver in the
light fixture, and they would be linked wirelessly.
Additional applications could tie in your house's sound system, climate
control, and energy monitoring, again, without any new wires, and
without pulling in excess energy. Right now, EnOcean products are used
mostly in industrial applications, monitoring warehouses and the like.
But with a few years of research, programmable houses might be a matter
of simply picking up a few things at WalMart.
We talk about all kinds of new fuels and how they will alleviate our
dependence on oil. But why don't we just make an engine that can run
on anything? Well, Russell Henning, a student at San Jose University
did just that. The Grasshopper, shown here, is a walk behind tractor
that has an engine that will run on anything
. Slash from a field, hay,
coconut shells, dried food waste, anything, as long as it's organic
and dry, can but put into the Grasshopper and the thing will run.
This is the first run-on-anything engine I've ever seen. Not only does
it find a use for all that trash, it's also a simple and inexpensive
machine that can increase productivity of farmers across the world.
This doesn't prevent CO2 emission, but it does lessen the amount of
mining and drilling needed to run a tractor.
