Hurricane Dorian is now a “catastrophic Category 5” storm and the strongest on modern record as it approaches the northwestern Bahamas in the Caribbean, according to a National Hurricane Center update today (Sept. 1).
As of 11 a.m. EDT (1300 GMT), Dorian has maximum wind speeds of 180 mph (285 km/h) as the storm churns about 20 miles (30 km) east of Great Abaco Island, the NHC wrote in the update. The storm is about 205 miles (330 km) east of West Palm Beach, Florida.
“Devastating hurricane conditions are expected in the Abacos Islands very soon and these conditions will spread across Grand Bahama Island later today,” NASA officials said today in a morning update.
As destructive natural phenomena go, hurricanes are among the heavyweights. If not for the gale-force winds and resulting projectile debris, then for the massive flooding that results when one makes landfall and stalls out, a hurricane is a nasty piece of work. Just ask the residents of the coastal Carolinas and Georgia this week as they wring themselves out from Hurricane Matthew’s weekend deluge.
If you’re looking to build a new home on coastal waters where hurricanes are known to roam, you might want to skip the two-by-fours and cement and instead start drinking bottled soda. A Canadian company has recently completed construction of a home with exterior walls made from recycled plastic, and it’s claimed to be able to withstand winds gusting at over 300 miles per hour.
Built by JD Composites, the three bedroom home is situated near the Meteghan River in Nova Scotia. Aside from a distinct lack of trees, gardens, and neighbors, the house looks like any other dwelling with a clean modern design and a minimalist facade. Inside it’s fully furnished and finished with drywall covered lumber walls, but the exterior is what makes the house appealing as a new, and seemingly much improved, approach to construction.
Over-conservative climate scenarios mean we could face ‘world of outright chaos’, says analysis authored by former fossil fuel executive and backed by former head of Australia’s military.
While solar and wind power are rapidly becoming cost-competitive with fossil fuels in areas with lots of sun and wind, they still can’t provide the 24/7 power we’ve become used to. At present, that’s not big a problem because the grid still features plenty of fossil fuel plants that can provide constant baseload or ramp up to meet surges in demand.
But there’s broad agreement that we need to dramatically decarbonize our energy supplies if we’re going to avoid irreversible damage to the climate. That will mean getting rid of the bulk of on-demand, carbon-intensive power plants we currently rely on to manage our grid.
Alternatives include expanding transmission infrastructure to shuttle power from areas where the wind is blowing to areas where it isn’t, or managing demand using financial incentive to get people to use less energy during peak hours. But most promising is pairing renewable energy with energy storage to build up reserves for when the sun stops shining.

If 150,000 volt stun guns aren’t enough to deter criminals, law enforcement might want to give Rob Flickenger a buzz.
The IT expert, who also has a bit of a reputation as a DIY mad-scientist, has a shocking new invention: a real-life lightning gun. Built over a period of at least 10 months, the zapper is the end result of combining the aim-and-shoot functionality of an aluminum-encased Nerf gun with the electrical power supplied by an 18V drill battery.

There’s no way to store toxic coal waste that’s completely safe. There’s also no way to mine and burn coal that doesn’t threaten communities, our waterways and our climate. Duke needs to stop burning coal, clean up its toxic mess, and invest in abundant, affordable clean energy sources like solar and wind. #2048istoolate #BeyondCoal #YEARSproject with Sierra Club.

Can bacteria generate radio waves?
On the face of it, this seems an unlikely proposition. Natural sources of radio waves include lightning, stars and pulsars while artificial sources include radar, mobile phones and computers. This is a diverse list. So it’s hard to see what these things might have in common with bacteria that could be responsible for making radio waves.
