แข่งขันลดปริมาณ CO2 ชิงเงินรางวัลกว่า 25ล้าน$

$25 Million CO2 Removal Challenge

• And in some new CO2 news, Branson and the Virgin Group are offering a 25 million dollar scientific challenge for the first person or team who can come up with the answer to the challenge of how to remove 1 billion tons of CO2 from the atmosphere a year, for ten years.
• 
  "The Virgin Earth Challenge is a prize of $25m for whoever can demonstrate to the judges' satisfaction a commercially viable design which results in the removal of anthropogenic, atmospheric greenhouse gases so as to contribute materially to the stability of Earth’s climate."..and more there at the (Flash heavy) link including contest details, who the judges are and how it will be judged, etc.

  Basically, you have transportation with liquid petroleum based fuels and centralized electricty production using coal. It wouldn't work everywhere, but a variation on the California "million solar rooftops" globally would go a long way to drop the need for so much coal burning, especially as AC demand is exactly at the same time as mid day solar maximum with PV panels, which works out nicely. With transportation, again, they can build electric commuter cars now (pick any few proposed car plants they want to close and just retool to make electric cars as a percentage of their entire corporate fleet sales to force the issue, not conventional hybrids, pure electrics or plug in hybrids with a 50 mile range) that are perfectly adequate for millions and millions of commuters, and those vehicles can be alternative energy-carbon neutral recharged to a great extent, especially if they are combined with the "million solar garage roof" concept. A package deal in other words..
  
  The way to reduce man made CO2 is to not remove it, it is to not put it there in the first place. We can also free up so much demand from coal fired electricity by mandating much tougher insulation and building code specs, even to the point of mandated retrofitting between owners and making it a condition of new permits and mortgages. Want to flip properties every other week? OK, no probs, go for it, but first they have to be brought up to the new stricter codes. sorry, but three inches in crappy thin walls with leaks all over is not any sort of long term "good cents". The concept and practice of "superinsulation" works so amazingly well it just isn't debatable much more. The most cost effective energy solution out there isn't producing more energy, just using what we do produce more efficiently. At this time I would call that true facts, and is much easier to pull off then Mr. fusion ITER reactor and switching everything to hydrogen boondoggles which would require completely rebuilding the entire transportation stack, a hugemongous proposition.. We have *practical* fusion power right now going begging, it is called the Sun. We have carbon sinks called plants. We can gradually go to better biofuels with only minor modifications to existing vehicles as they are produced, the flex fuel concept, which all new vehicles should be capable of, all the way to 100% biofuel..
  
  If I hadn't participated with some superinsulation builds and seen it with my own peepers I might want to argue about it or be a little skeptical, but really can't, not when I saw just dramatic drops in furnaces coming on or ACs kicking in. It falls into the "amazing" category really, something that ANY construction crew can adapt to easily.. It's like the diff of keeping your cold drinks in a paper bag on your picnic or in a well built cooler. and if I hadn't lived for four years with whole house solar I might be skeptical as well, but saw it work, even through back to back cloudy days.
  
  Anyway, ya I know this does nothing about the 25 million buck challenge of removing the extra gases. All I can say is green the planet back up. Big trees work, a healthy ocean works, dark shingles on roofs provide zero electricity. Man made heat sink and concentrated pollution islands called major urban areas might also need to be readdressed in how they are designed and built as just being massive energy users and not producers. We need to put production close to demand to gain efficiency, and to drop demand with better engineering.
