Not only will this improve your aerobic fitness, but all your "journeys in and out of the UK" could help overload this stupid system
Can you come up with a protocol that will not allow a zombie box to, as you say, authenticate properly?
Yes. ISPs should ask for an additional fee to provide email access. Most people use free GMail/Hotmail/other Webmail and will never bother to enable local email, therefore most zombie boxen will not be able to authenticate properly and send.
Aren't some solar panels made with GaN as well? Will this help them too?
Looks likely. Cambridge are researching that too, e.g. both fields are covered by the following grant application.
The other approach to solar cells we will pursue is high-efficiency inorganic multilayer solar cells. The basic idea is that by stacking layers in the order of their bandgap, with the layer with the largest bandgap at the top, light is converted into electricity in the most efficient way. We propose to build an innovative multi-layer solar cell based on GaN/InGaN/Si. The GaN layer will absorb the UV part of the solar spectrum, the InGaN layer the blue and green parts and the Si layer the yellow, red and near-IR parts. The theoretical efficiency is above 60%. Such a cell would be too expensive for large-area applications, but would be designed to be used at the focus of mirrors that concentrate the solar light, which will make the technology competitive.
GaN-based white lighting is extremely efficient and if used in our homes and offices it could save 15% of the electricity generated at power stations, 15% of the fuel used, and reduce carbon emissions by 15%. However for GaN-based white lighting to become widely used in homes and offices we have to increase the efficiency still further and reduce the cost. We will research various ways to increase the efficiency. To reduce the cost we will grow GaN-based LED structures on 150mm (six-inch) silicon wafers instead of the current growth on two-inch sapphire wafers. This would reduce the LED cost by a factor of ten. Cambridge will grow such LED structures and UCSB will process them into LED lamps.
So from what I can tell, reducing consumption (and waste) of a commodity is good for the economy, but not necessarily for the environment. However, switching to an alternative "cleaner" commodity that costs the same *is* good for the environment, but neutral to the economy.
Yes, and unfortunately No. "Switching to an alternative "cleaner" commodity that costs the same" increases demand for the clean commodity and hence slightly increases its price, while slightly decreasing demand for the dirty commodity and hence decreases its price. Basically whenever you do something green, the incentives shift slightly to encourage your neighbor to pollute more.
One example is that I ride a bike, so I don't need my resident's parking place. But it doesn't stay empty. What happens is that the slightly easier availability of local parking just tips the decision in favor of one of my neighbor's buying an additional car, and there is always someone else's car filling my "un-needed" parking space. Worse, because this other car buyer is less "green" than me, the car in front of my house is more polluting than any I would have bought and parked there. So my "green" buying decision is bad for the environment.
The problem with using a single number is simple: It is easily gamed and there's lots of incentive to do so
Exactly. And one easy way to game the system is to bet that the authorities will always act to keep markets stable, which you can do by taking risks that would otherwise be stupid. In other words, traders are incentivized to leech off the taxpayer. I'm surprised the crash took so long.
There are many times I repeat the exact same many-step procedure in Office. Why doesn't Office notice and offer to make a macro or menu item out of what I'm doing?
Because that would be a big disincentive to upgrade. If Office N has created a lot of custom macros for you, you're unlikely to buy Office N+1 and risk them not working.
"no one should be killed or injured in a Volvo car."
Actually this laudable goal is very easy to achieve. Simply kill the driver and passengers before they get into the Volvo car. For example use a huge blender, then pour them through a window. Not so "stupidly ignorant" after all, Mr Reality Master!
Mr Brown said nurse sharks and other species of carpet shark which spend most of their time lying on the bed of the tanks, could be the best barometers for the impact of those pop tunes. Their reactions will tell the researchers whether the sharks are enjoying the music or whether it turns them off.
Everyone knows sharks must swim or die and, when the alternative was Christmas pop songs, they've made their choice.
