California Department of Public Health Issues New Warnings about Cellphone Radiation Exposure. Again.

I’ve written before about the potential dangers of exposure to cellphone radiation. Considering our collective addiction to cellphones and the known levels of radiation emissions coming from cellphones, I’ll likely write more about this topic again in the future, unless somethings change about both the ways in which we use our cellphones and the way manufacturers protect consumers from known levels of cellphone radiation emmission. Now the state of California Department of Public Health has reissued warnings and suggested guidelines for safe useage of these radioactive devices.

These new warnings from the CDPH are far from the first round of dire warnings that the state of California has issued about the dangers of cellphone radiation exposure. Far from it. It’s just the most recent in a long line of warnings that the California Department of Public Health has issued about our collective and continued exposure to cellphone radiation.

Now, it’s worth mentioning that despite California’s warnings, there are other scientific studies that do not reach the same conclusions that the state of California has. Nonetheless, it would seem to me that exercising an abundance of caution when dealing with potentially carcinogenic radiation is both wise and prudent, especially if you have children who use these devices, since they are more susceptible to the harmful effects of close range radiation exposure over time. Not to mention, even if you scoff at the warnings and guidelines issued by the state of California, it’s worth keeping in mind that despite the fact that Apple (and the other smartphone manufacturers) have their own clear and concise warnings and cautions when it comes to usage of their devices, relatively few of us follow even those minimal precautions.

For instance according to the manufacturers, cellphone radiation isn’t safe when you carry said radioactive device in your pocket or hold said radioactive device up against your skull, or let your children hold it against their significantly thinner skulls. And yet, most of us persist, as if oblivious to the manufacture’s own warnings that come with the devices in question.

The recent California state warnings about cellphone radiation exposure include taking the following precautions:

  • Keeping the phone away from the body.
  • Reducing cell phone use when the signal is weak.
  • Reducing the use of cell phones to stream audio or video, or to download or upload large files.
  • Keeping the phone away from the bed at night.
  • Removing headsets when not on a call.
  • Avoiding products that claim to block radio frequency energy. These products may actually increase your exposure.

When all is said and done, it’s up to each of us to decide how we choose to use our technological devices, just like it’s up to each of us to decide whether or not to smoke cigarettes, or spend hours on end in the summer sun without sunscreen. Personally I’ll choose to listen to the science and words of warning coming out of California, and err on the side of caution.

A Tesla Semi Prototype Spotted in California is Swift, Sleek, and Silent

Swift and Silent

Tesla’s electric semi-truck is not only more environmentally friendly than its competitors, but it is also quieter than the typical diesel-powered truck that barrels down the street. An eight-second YouTube video, first revealed by Inverse, shows a sleek Tesla Semi prototype gliding swiftly and almost silently through an intersection in Sunnyvale, California, near the company’s Palo Alto headquarters. Watch it below.

The prototype features impact-resistant glass, a streamlined cabin design, and the ability to accelerate from zero to 97 km/h (60 mph) in five seconds when not carrying cargo. After pushing back the unveiling date twice due to Tesla’s Model 3 production delays and the company’s humanitarian efforts in Puerto Rico, CEO Elon Musk finally unveiled the much-anticipated Tesla Semi prototype in November 2017.

Revolutionizing Hauling

Though the lowest-priced model costs a cool $ 150,000, the truck is supposed to travel 483 km (300 miles) on a single charge. The more expensive $ 180,000-model can go even farther, with a range of 805 km (500 miles). While those costs were higher than some analysts anticipated, Musk asserted that the electric semi costs less to operate than typical diesel rigs by about $ 0.16 per km ($ 0.25 per mile).

Though the vehicle isn’t scheduled for production until 2019, companies are already buying into Musk’s sales pitch of a cheaper, greener truck en masse. By the end of 2017, 18 companies — including Walmart and Pepsi Co. — had pre-ordered at least one truck. UPS topped the list, reserving 125 vehicles.

Hopefully, Tesla’s production team will be able to keep to Musk’s scheduling promises. But the odds could be slim, given that the company’s Model 3 electric car production fell well short of Musk’s 2017 goals. Delayed production or not, however, this new YouTube footage reveals that the new truck will be making our streets quieter whenever it does finally hit the road.

Greenlots joins PG&E program to roll out EV chargers in California

Greenlots joins PG&E program to roll out EV chargers in California

Electric car charging specialist Greenlots is to take part in Californian utility PG&E’s EV Charge Network as a services provider.

Electric vehicles (EV) sales are rising fast – but in order to make the leap, would-be owners need to feel confident that they will be able to reach a charging station whenever they need to power up their car.

In California, EV charging specialist Greenlots has announced plans to participate in the new EV Charge Network program from Californian utility Pacific Gas & Electric Company (PG&E), providing installation and management of EV chargers, site recruitment, and delivery of software solutions.

With its programme, PG&E has committed to installing 7,500 chargers at workplaces in Northern and Central California over a three-year period.

Greenlots executives, meanwhile, say they are working to “empower utilities”, so that they can meet the demands of this major market shift in a sustainable way.

Putting customers first

Greenlots plans to fit businesses, apartment buildings, condominiums and universities with its charging equipment. The company will be just one of a list of pre-vetted vendors, tested for quality and safety standards, from which customer sites can choose.

Participating organisations can call on Greenlots to deliver turnkey charging solutions. And to give them broad choice, the company will partner with Delta, SemaConnect, AeroVironment and EVBox.

Greenlots executives said that its announcement comes at a time when its “network size and charger utilisation rate continue to grow rapidly”, particularly in California. On average, they claim, Greenlot’s charging-station footprint in California is growing at a rate of around 16 percent per quarter and its network utilisation rate at 19 percent per quarter. 

Electronic vehicle charging programmes have been a huge success in California since, in 2012, Governor Jerry Brown signed an executive order demanding 1.5 million zero-emission vehicles on the roads by 2025.

Brett Hauser, CEO of Greenlots, said: “With over a quarter of US EV drivers located in PG&E’s service area, it is critical that we ensure charging infrastructure is both reliable and broadly accessible. By participating in this program, Greenlots continues to chart a path towards a clean, electrified transportation future.”

California Is Officially Planning to Ban Polluting Cars by 2040

Pollution phase-out

Efforts to free California from polluting vehicles once and for all are finally taking shape, as a bill that would ban fossil fuel-powered cars by 2040 has been officially put on the table by California Assemblymember Phil Ting.

Ting has delivered on the idea he had introduced last month, and now the bill is up for approval.

While the state is already on track to meet its renewable energy goals a staggering 10 years ahead of schedule, this bill, called the Clean Cars 2040 Act, could drastically cut emissions and make California a real pioneer in the fight against climate change.

Now, this bill wouldn’t pull all polluting vehicles from the road,  but it would prohibit the sale of any new car or truck running on fossil fuels. All new passenger vehicles sold in California would have to be “zero-emissions vehicles” like battery-electric or hydrogen fuel cell cars. Speaking about the importance of the new bill, Ting said: “we’re at an inflection point: we’ve got to address the harmful emissions that cause climate change.”

A Zero-Emissions Future

As many work to reduce emissions, especially in the state of California, some might suggest that setting such a rigid timeline is drastic or unnecessary. But Ting explained observed that “until you set a deadline, nothing gets done.”

While emissions come from a variety of sources other than cars, in his speech Ting reminded that “vehicles [that] run on fossil fuels are responsible for nearly 40 percent of California’s greenhouse gas emissions.”

Not only the new measure could deliver important environmental benefits, but it also makes business sense. The fact sheet accompanying the bill makes a case for staying ahead of the green trend: “Great Britain, France, China, India, and other countries are phasing out gas and diesel-powered vehicles, and requiring new vehicles to be zero emissions,” the document states.

It notes that the four countries account for over 35 million new vehicle sales per year, and the global automobile industry will have to meet the new needs with a full range of zero emission vehicle options. “By aligning its 2040 requirement with these and other countries,” the note adds, “California can keep pace with the world and take advantage of this coming market shift.”
